A Virtual Private Server (VPS) is a type of hosting service that provides dedicated virtualized server space on a physical server. Essentially, a VPS mimics a dedicated server environment within a shared server.
This setup is made possible by using virtualization technology, which splits a single physical server into multiple smaller virtual servers. Each VPS has its own operating system, storage and bandwidth, which are isolated from other servers on the same physical machine.
Think of a VPS as an apartment in a high-rise building. While all the apartments share the same infrastructure (building, elevators, utilities), each unit is separate and offers privacy and control to its occupant. Similarly, a VPS offers users their own private space to run applications and websites independently, without interference from others using the same physical server.
Imagine a homeowner with a nice yard pays a landscaping crew to take care of their lawn and garden. While the homeowner is physically able to do these tasks on his own, he may not have the time needed or the skills to make his garden perfect like a professional crew. Additionally, he probably doesn’t have the tools to get the job done to professional standards and he has his own full time job to worry about. For all these reasons it becomes sensible to pay for an ongoing service that specializes in gardening.
Why are VPS Important in Decentralized Ecosystems?
Virtual Private Servers are crucial in the context of web3 and decentralized networks due to their flexibility, cost-effectiveness and scalability. They provide an ideal solution for running nodes, decentralized applications (dApps), and other blockchain-related services without the high cost associated with dedicated physical hardware.
Cost-Effectiveness: For those who want the power of a dedicated server but at a fraction of the cost, a VPS is a perfect choice. This makes it more accessible for developers and node operators to get involved in decentralized projects.
Scalability: VPS instances can be easily scaled up or down depending on the needs of the network or application. This is especially useful in blockchain environments where usage patterns can fluctuate greatly.
Flexibility: VPS users have root access to their servers, allowing for a high degree of customization. This means they can install and configure any software required to run their specific decentralized application or node.
VPS in the Gala Ecosystem
Gala Founder’s Node operators often utilize Virtual Private Servers to run multiple nodes efficiently. Running nodes on a VPS allows operators to avoid the logistical challenges and high costs of maintaining multiple physical machines. By using VPS, node operators can ensure that they have enough memory, processing power and bandwidth to support their nodes without the need for additional hardware.
The Gala Founder’s Node ecosystem is made up of dedicated community members who wish to power a portion of the network in exchange for some computing power. If a community member wishes to run 5 nodes, for example, they can either scale up their hardware and internet service to accommodate their workloads, or they can simply operate their nodes on a virtual private server, using one of many trusted VPS services available to them.
Benefits of Using VPS for Node Operations
Resource Optimization: A VPS can be customized to allocate the exact amount of CPU, RAM, and storage needed to run multiple nodes. This avoids the over- or under-utilization of resources that can occur with physical servers.
Easy Maintenance and Management: With a VPS, operators can remotely access and manage their nodes from anywhere in the world. This remote management capability simplifies the process of maintaining and upgrading nodes.
Reliability and Uptime: Reputable VPS providers offer high uptime guarantees and automated backups, ensuring that nodes remain online and functional even in the case of unexpected issues.
Security: VPS environments are typically more secure than shared hosting services because they offer isolated instances. This isolation means that security vulnerabilities in one VPS do not affect others on the same server.
Why VPS is an Ideal Solution for Decentralized Networks
In the context of decentralized networks and web3 projects, VPS instances provide a stable and reliable way to run nodes and other network services. Some of the reasons why VPS is particularly suitable for this use case include:
Decentralization Without High Costs: VPS allows individuals to participate in decentralized networks without the prohibitive costs of physical servers. This aligns well with the ethos of decentralization by lowering the entry barrier for participation.
Geographic Distribution: VPS can be deployed in data centers around the world, contributing to the geographic decentralization of the network. This ensures that the network remains robust and resistant to localized disruptions or attacks.
Flexibility for Different Roles: VPS can be used to run different types of nodes—validator nodes, storage nodes, and more—allowing operators to contribute in various ways depending on the network’s needs.
The Future of VPS in Web3
As web3 continues to grow, the demand for decentralized infrastructure solutions will only increase. Virtual Private Servers will continue to play a crucial role by providing a bridge between the scalability needs of large networks and the accessibility required by smaller operators. As projects like GalaChain and others evolve, the ability to quickly deploy, scale, and manage nodes using VPS will become a fundamental part of ensuring that decentralized networks remain performant and resilient.
Welcome back to another edition of DevSpeak! In this series, we’re all about filling you in on the basics of terms you’ve probably heard tossed around in tech circles without fully understanding what they mean. Today, we’re diving into one that’s been around a while but is still causing its fair share of confusion – cloud computing!
Imagine you’re organizing a huge event. You could either buy everything yourself—chairs, tents, catering equipment—or you could rent all of these items for the day, using them only as long as you need, and then return them. This is more or less how cloud computing works for businesses and individuals in today’s world.
Cloud Computing, Defined
At its core, cloud computing is the delivery of computing services such as storage, processing power, databases, and software over a shared connection, often referred to as “the cloud.” Instead of owning physical hardware or software on your premises, you access and use these resources online, typically through a service provider like Amazon Web Services (AWS), Microsoft Azure or Google Cloud.
Think of cloud computing like using electricity. You don’t need to own a power plant to run your lights, fans, or electronic gadgets. You simply plug into an outlet and pay for the amount of electricity you consume. Similarly, cloud computing lets you “plug into” vast computational resources and only pay for what you use without owning any of the underlying infrastructure.
While this cloud connection typically happens over a standard internet connection, providers typically create permissioned and secure ways to access resources.
The Silver Linings of the Cloud
There’s lots of ways that the idea of the cloud has been amazingly beneficial in people’s lives. We often don’t even think about all the ways we interact with cloud services today, even though many things we do are facilitated by cloud computing under the hood.
Cost Efficiency
Using the cloud means you may not have to buy expensive hardware or software upfront.
Imagine a startup needing 100 powerful servers for just one week to run some tests. Buying 100 servers would be incredibly expensive, and those servers might sit unused afterward. Instead, they can rent these servers in the cloud for the short time they need them and save a lot of money.
Scalability
Let’s go back to our party example. Oh no! More guests showed up than expected! You’ll have to scramble for more chairs, tables, and food.
In traditional computing, if your website traffic unexpectedly spikes, you’d need to buy more servers – expensive and time consuming. With cloud computing, however, resources can scale automatically. If your needs grow, you can instantly be allocated more computing power or storage from the cloud. Similarly, if traffic drops, you only pay for the reduced amount of resources used without having bought extra servers you don’t need anymore.
Flexibility
When all the tools are yours, your flexibility is limited to your toolkit.
Cloud computing allows businesses to be flexible in how they use their resources. If your project requires more computational power for a short period, you can ramp up easily without complicated logistics. If you need less, you can scale back. No long-term commitments are required, and there are enough cloud providers out there that they have an interest in keeping their customers happy.
Accessibility
Physical servers are in a place, and setting up secure ways to access your resources anywhere you want is complicated and a potential security risk. The cloud is already set up for this.
The cloud allows you to access files and applications from anywhere in the world, as long as you have an internet connection. No matter where you are, you can access the tools you need.
The Darker Side of the Cloud
While cloud computing has plenty of benefits, it’s not without its downsides.
Security and Privacy Concerns
When you rent something, you don’t have full control over it. You have to trust whoever does have full control over it.
When you store your data on someone else’s servers (in the cloud), there’s a risk of breaches or data leaks. While cloud service providers invest heavily in security, they can still be targeted by hackers. Not all cloud services are equal – look carefully at the ToS on a cloud provider and make sure you’re comfortable with the level of access they themselves have to your data.
Downtime and Outages
Back to the party example — delivery truck is stuck in traffic. Nothing you can do. You’ll have an event without seating for a while.
Even large cloud providers experience outages. If their systems go down, you could lose access to your tools and resources. It’s worth noting that they typically will know what they’re doing and work hard to fix problems. Being out of control can be hard, however, and with cloud services you’ll have to accept that there may occasionally be issues that are out of your hands.
Ongoing Costs
While renting might save you money upfront, long-term rental fees can add up. For some businesses, using the cloud can become more expensive over time than buying your own resources.
Cloud services do what they do because they’re trying to make money. Expanding your own infrastructure can save you money in the long run, so it’s important to make sure that cloud computing you use is mutually beneficial.
Vendor Lock-In
One more visit to the party example. Let’s say that delivery truck does show up, but they brought double the tables and no chairs! At this point, it’s tough to get another truck from another company out there without sending away the one that has the rest of your party supplies… even if minus chairs.
Switching between cloud providers isn’t always simple. Each provider has different systems, and moving your applications and data from one to another can be time-consuming and costly. It’s best to do research on any cloud provider you work with an ensure that you’re pretty likely to be happy with their service.
Parting the Clouds
Cloud computing has revolutionized the way we think about accessing and using digital resources. By making powerful tools available over the internet, the cloud has changed the way both businesses and individuals interact with the digital world. However, like any technology, it comes with trade-offs – just because something can be handled on the cloud doesn’t mean it always should.
Much like renting versus owning, cloud computing allows companies and individuals to use what they need when they need it, without the hefty upfront cost. The functionality that these services have unlocked across the whole of the internet has opened up new ways to build, collaborate and navigate life.
That’s it for today, but we’ll be back soon with another DevSpeak!
Artificial Intelligence (AI) often sounds like something straight out of a science fiction movie—robots taking over the world or computers that think and act like humans. But the reality of AI is much different and far less scary. AI is already a significant part of our lives, helping us in ways we might not even realize.
Artificial Intelligence, Defined
At its core, Artificial Intelligence is simply the ability of a machine to perform tasks that would normally require human intelligence. These tasks can include things like understanding language, recognizing patterns and solving problems.
AI is just a tool designed to mimic certain aspects of human thinking or behavior. But it’s important to note that AI doesn’t have feelings, consciousness, or self-awareness. It’s just a set of algorithms—basically, step-by-step instructions for processing data and making decisions based on that data.
For example, when you use voice commands to ask your smartphone for the weather, AI is at work. It understands your question, searches for the information, and provides you with an answer—all in a matter of seconds. But it’s not “thinking” the way humans do; it’s following a programmed sequence of actions based on the input it receives from you… a thinking, creative human.
General vs. Narrow AI
Now that we know what AI is, it’s crucial to understand that there are two main types: General AI and Narrow AI.
It’s a little more complicated than just General and Narrow. If you want to dive deeper into the types of AI, check out this video from IBM.
Narrow AI
This is the type of AI we interact with daily. Narrow AI (often referred to as weak AI) is designed to perform a specific task or a set of related tasks. It’s very good at what it does, but it’s limited to that particular function. A facial recognition system can identify people in photos, but it can’t play chess or write a song.
These types of AI can seem deceptively intelligent, but that’s because it’s trained to be incredibly proficient at one thing. As humans, we tend to recognize someone who is really good at something as very capable. AI is not a human. Just because it’s impressively responsive as a chat bot doesn’t mean that it has real insight or understanding of anything it’s been trained on.
Search engine algorithms are a great example of this. Google seems like it knows everything about you sometimes. It places ads at the exact right time. Have you ever gotten an ad on YouTube for something that you were just thinking about but never voiced aloud? Spookily insightful, huh?
Only it’s not. Google’s algorithm has sampled terabytes of data on literally billions of people. It is excellent at seeing the patterns and knowing that if you searched for A and you purchased B, you’re likely going to think about C sometime in the next few days. This doesn’t mean it knows you, it just knows what humans are likely to do.
General AI
This is the kind of AI you see in movies — machines that can think, learn and apply knowledge across a wide range of tasks, just like a human. However, General AI (referred to as strong AI) doesn’t exist yet. While there’s some disagreement about how long, we’re still definitely a long way from creating a machine that can do everything a human can do.
To accomplish this, we’d need to make algorithms that can do everything the human brain can. The problem with that is that we don’t really understand how our brain does its thing entirely. Even if we can simulate the number of neurons and interconnections in a human brain (a BIG task), will that equate to learning, insight and creative thinking? Is a brain just a computer or something more is a question that science hasn’t come very close to answering.
Recent studies indicate that we may be even further from General AI than we thought. Some recent evidence suggests that human reasoning may actually be using an unprecedented macroscopic quantum system throughout our bodies, giving rise to what we think of as “consciousness”. If that or anything like it is the case, we’re orders of magnitude further from general AI that can compare to human intelligence than we thought we were.
Regarding GPT: Understanding Large Language Models
Let’s take a short digression to talk about one of the most ubiquitous forms of AI out there – the Large Language Model (LLM), used in programs such as GPT (Generative Pre-trained Transformer). Since these specialize in one of the cornerstones of civilization (communication), they’re easy to overestimate or misunderstand. After all, we typically see the ability to communicate well in humans as a sign of intelligence.
Large Language Models (LLMs) are a type of AI designed to understand and generate human-like text based on the input they receive. They are trained on vast amounts of text data, allowing them to learn patterns, grammar and even some aspects of reasoning. When you ask GPT a question or give it a prompt, it analyzes the input and generates a response that seems coherent and relevant, often mimicking human language quite convincingly.
How GPT Forms Responses
When you interact with GPT, you’re essentially giving it a prompt – a piece of text that it will use as a starting point to generate a response. GPT doesn’t “think” or “understand” the way humans do. Instead, it uses the patterns it has learned during training to predict what text is likely to come next based on the input it received.
If you ask GPT to write a story about a cat, it’ll use the knowledge it has about cats, stories and language structure to craft a response. The more detailed your prompt, the more focused and accurate its response will be. It isn’t actually composing a story… it’s just giving a response that sounds like something a human may say.
Limitations of LLMs
While LLMs like GPT are incredibly powerful, they have significant limitations:
Lack of understanding: LLMs do not possess true understanding or consciousness. They generate text based on patterns, not on any deeper comprehension of the world. This means that while GPT can produce text that seems intelligent, it doesn’t actually “know” anything in the way humans do.
Dependence on training data: LLMs are only as good as the data they’ve been trained on. If the data is biased or incomplete, the model’s responses may also be biased or inaccurate. Additionally, GPT cannot create entirely new knowledge; it only recombines and reinterprets what it has already been exposed to.
Inability to think critically: GPT and other LLMs cannot critically evaluate or verify information. They can sometimes generate responses that are factually incorrect or nonsensical, particularly if the prompt is ambiguous or outside the model’s training scope.
You can train a parrot to respond to specific phrases with almost conversational quips… that doesn’t mean the parrot is carrying on a conversation with you. LLMs are similar to that in lots of ways. The AI is learning what responses to a prompt are likely to be appropriate based on the data it is fed. It’s complex, but it’s still just parroting the data it’s been given.
Apocalypse, Not
One of the biggest myths about AI is that it will eventually become so intelligent that it will take over the world, causing an “AI apocalypse.” This idea is more fiction than fact.
Remember, Narrow AI is designed to do specific tasks. It can’t suddenly decide to become something else. Your AI-powered vacuum cleaner isn’t going to start plotting world domination… it’s just going to keep cleaning your floors. Even if we one day develop General AI, the idea that it would turn against us is highly speculative and far from a present concern. It’s also likely that generations of sci fi writers have been assigning scary, but fundamentally human characteristics to a theoretical, inhuman system.
In reality, AI is just another tool. As people understand more of this, another alarmist point of view has become prevalent – the idea that AI will replace all of us. Again, this goes a little far. There are parts of life that AI has already made more efficient, but it’s just a tool.
The invention of the power drill didn’t replace carpenters. Often human expertise is still required to get the best work out of these AIs. Writing from GPT will feel choppy and generic if it’s not edited by an expert. Images generated by non-artists from Midjourney often still lack the composition and cohesion that an artistic eye with experience can bring.
You could give me (a writer) a powerful data aggregation algorithm, and I would be totally lost and would probably just waste time on it. To a data analyst, it can be a super power for tedious and mundane tasks that previously sucked their time dry. The expertise from a real human is still required to get the best work out of AI.
Human Intelligence Boosted
Hopefully this DevSpeak gives you a lot more insight into the very broad term “AI”, and how it affects your daily life. New tech and the jargon that comes with it is often confusing, but that’s why you have DevSpeak!
This one was a mouthful for sure! Thanks for sticking with us through this deep dive on an important topic. We’ll be back soon with more explainers designed to buff your understanding of the tech world!
There’s a lot of jargon in the tech world. Sometimes, you may understand these terms on their face, but their nuances in relation to technology takes a bit of deeper understanding. Luckily, DevSpeak is here to have your back.
You’ve probably frequently heard terms like “bandwidth,” “throughput,” and “network speed,” especially when discussing internet connections. But what do these terms really mean, and how do they impact your online experience? For those new to tech, understanding these concepts can be confusing. People regularly lament, “but I have a fast connection!”, in response to data speed problems… but the speed of your connection is only one factor in determining data transfer speed and efficiency.
In today’s DevSpeak, we’ll dive into these terms so you can confidently understand what each does and doesn’t mean. Use this knowledge wisely to understand your digital connections better… and to not put your foot in your mouth the next time you’re having a casual conversation with a developer.
Bandwidth, Throughput, and Network Speed, Defined
Let’s grab a very basic analogy here and hold it close as we explore these terms. Think of your internet connection as a highway. There’s lots of data packets trying to get through on the highway both ways.
Bandwidth: Think of this as the highway itself. Bandwidth is the total width of the road—the number of lanes available for cars (data) to travel on. The more lanes you have, the more cars can travel at the same time. In technical terms, bandwidth refers to the maximum amount of data that can be transmitted over a network in a given amount of time, usually measured in megabits per second (Mbps). Just because you have a solid maximum bandwidth, however, doesn’t mean you’ll always transmit data at those speeds… highways have other things that slow down traffic.
Throughput: Now, consider the traffic on the highway. Throughput is the number of cars that successfully reach their destination per unit of time. Even if you have a wide highway (high bandwidth), the actual traffic (throughput) might be lower due to various factors like road conditions or accidents. In network terms, throughput is the actual amount of data that gets successfully transmitted from one point to another over a given period of time.
Network Speed: Finally, network speed is the time it takes for a car to travel from point A to point B. It’s influenced by both bandwidth and throughput, but also by the car’s speed (latency). If the road is clear and cars are moving fast, data reaches its destination quickly. Network speed is often what people refer to when they talk about how “fast” their internet connection is, though it’s really a combination of several factors.
Different Metrics for Different Network Capabilities
These three terms — bandwidth, throughput, and network speed — each describe different aspects of your internet connection’s performance:
Bandwidth determines the potential maximum capacity of your connection. Think of it as the upper limit.
Throughput shows how much of that potential is being used effectively, giving you a realistic measure of your current connection.
Network speed impacts your experience of using the internet, like how fast pages load or how quickly you can stream videos.
To continue with our highway analogy, you could have a wide road (high bandwidth) but still experience slow traffic (low throughput) due to construction work or traffic jams. Similarly, even with good traffic flow (high throughput), if your cars (data packets) aren’t moving fast enough due to speed limits (latency), you’ll feel that your network is slow.
Let’s step outside of our analogy for a minute here. Keep in mind that data transfer is a 2-way issue. While you may be sending data packets efficiently and quickly, perhaps the other side of that connection is experiencing difficulties. Maybe a data center in between the two endpoints is congested. It’s a big internet, and it takes two to tango.
Not All Connection Problems Are Equal
Understanding these distinctions helps explain why sometimes your internet feels slow even if you have a high-speed plan. For instance:
Congestion: Just like rush hour on a highway, too many users online at the same time can lead to lower throughput, even if you have high bandwidth. Try connecting to two games, spinning up several YouTube videos and opening 42 tabs on Chrome to experience this limiting situation.
Latency: If your data takes a long time to travel across the network, it doesn’t matter how much bandwidth you have—your experience will still feel sluggish. Often this can be because of how far data is traveling, or how many stops in between. A ping test to the address you’re transmitting to can give you a good idea here. Ping is measured in ms, and tells you how long a signal takes to go to the other side and come back to you.
Packet Loss: Imagine some cars not reaching their destination at all due to accidents. In networking, this is called packet loss, and it can drastically reduce throughput. This one can be tougher to isolate into one experience… but trying to connect on bad wifi is usually a pretty good parallel. Try sitting with your laptop outside with a yard sprinkler between yourself and your wifi router. Those water droplets are each scattering part of your data stream, leading to lost packets that never make it to your laptop or to their destination.
When troubleshooting a slow internet connection, it’s important to consider all three factors—bandwidth, throughput, and network speed. The problem is usually a combination of them, but rarely in equal proportions. Deal with the biggest issue first, then reassess the situation.
Knowledge Transmitted
Understanding the differences between bandwidth, throughput, and network speed can help you make informed decisions about your internet service and troubleshoot connection issues more effectively. Remember, a wide highway (bandwidth) doesn’t always guarantee smooth traffic (throughput), and how fast you can get from point A to point B (network speed) depends on several factors working together. Once you grasp, you’ll be better equipped to navigate the digital highway with confidence.
Hopefully this DevSpeak showed you how to more confidently conversate about these networking topics and also gave you some practical knowledge about connection problems that we all face from time to time in our digital lives.
Even if you’re not the most techy person in the world, these are important concepts that everyone should know at least a little about. We’ll be back again soon with another DevSpeak to bring you more clarity to the confusing terms tossed around tech!
Welcome back to another DevSpeak, where we decode the often confusing language of developers in a way that you can understand. Speaking of decoding, today we’re diving into a concept that is entirely ubiquitous in the web3 world… but not often understood. Today we’re diving into encryption!
If you’ve heard the term but are unsure what it really means, you’re not alone. Let’s break down what people mean when they say “encryption” and explore why it’s crucial for your digital safety.
Encryption, Defined
Encryption is a method of converting plain, readable information into a coded format that only authorized parties can decipher. If bad actors intercept your data, it’s gibberish to them without the proper cipher. Security measures use complex algorithms to ensure reliable encryption of information.
This isn’t just a process computers can do – you’ve probably encountered the idea of ciphers and code before in entertainment or history even if you don’t have super secret coded messages to send around.
You use a set of rules to replace each letter with another symbol or letter. To anyone who doesn’t know the code, the message looks like a jumble of symbols. But if you have the cipher, you can easily decode the message and read it as it was originally written. That’s the essence of encryption.
Remember these puzzles from newspapers? Classic encryption problems!
This is an old, old practice. In fact, one of the most classic examples of this is Cesarian Code, a method reportedly used by Julius Cesar to send coded messages to his legions.
In this method, you move each letter back three positions in the alphabet, revealing the true letters. While this method is obviously not secure after kicking around for 2100 years, there are many variations that are still used in manual ciphers today.
When the Fuzzles were lost in the wormhole in 2022, they used a slightly modified version of the Cesarian cipher to communicate with Earth! For extra security and interplanar transmission strength, they altered the amount of position offset and converted the entire message to binary.
Why Encryption
So, why is encryption so important? The primary reason is privacy and security. Every time you send an email, make an online purchase, or log into your bank account, your personal information is transmitted over the internet. Without encryption, this data could be intercepted and read by cybercriminals, leading to identity theft, financial loss, or other serious breaches of privacy.
Consider that when you shop online, for instance, you’re entering sensitive details like your credit card number and home address – that info is being sent from your computer to a server somewhere else, then probably to a datacenter in an entirely different location! If the website you’re using doesn’t employ encryption, those details could be easily stolen by someone who’s able to intercept the data transmission. Encryption ensures that even if someone tries to steal your information, it’s unreadable without the decryption key.
Encryption also plays a crucial role in securing communications between individuals and organizations. When you use messaging apps or email services that offer end-to-end encryption, only you and the intended recipients can read your messages – they aren’t accessible by any other party during transmission. This makes sure there’s confidentiality in conversations.
Not All Encryption is Equal
It’s important to know that not all encryption is created equal. In the most basic sense, there are two main types of encryption. Their effectiveness can vary based on how they’re implemented.
Symmetric Encryption: This method uses the same key for both encrypting and decrypting information. It’s like having a single key to lock and unlock a diary. It’s fast and efficient, but the main challenge is securely sharing the key between parties. If the key is intercepted, the encryption is useless.
Asymmetric Encryption: This method uses a pair of keys—a public key and a private key. The public key encrypts the information, while the private key decrypts it. This approach is like having a public lock that anyone can use to securely send you a message, but only you have the private key to unlock it. This method enhances security, especially in scenarios where secure key exchange is challenging.
Sound familiar? We dove into the details of symmetric vs asymmetric encryption in our second article in The Guardian Papers!
While encryption is a powerful tool, it’s not foolproof. The security of encrypted data depends on the strength of the encryption method, the management of encryption keys and the overall security practices you use to protect your data.
Frqfoxvlrq
In a world where our personal and professional lives are increasingly dependent on digital security, a basic understanding of encryption is more important than ever. Encryption is constantly protecting your activity every day!
Uh oh, did we leave the heading encrypted? Your first test begins!
The details of how encryption works can be complicated in practice, but the basic why and how of this practice are easy to understand. It’s about safeguarding your privacy and ensuring that only you and those you choose to share your information with can access your data.
Hopefully this DevSpeak gave you enough insight to not be totally lost the next time you go out on the town with your techy friends. We know that not everyone is or will be a tech expert, but understanding the basics of these concepts is important to not only use technology to its full potential, but also prepare you for the next wave of advancements!
Let’s all be ready for the world of tomorrow together!
Have you ever been listening to someone who works deep in an obscure niche of tech talk only to realize that you only understood two out of the nine words in that last sentence? It’s ok. Most of us have been there.
Welcome back to DevSpeak, where we dispel confusion around dense tech jargon. Often people who are fully capable of understanding some big topics in technology are pushed away, simply because they don’t know the lexicon. No more! DevSpeak is here to clarify!
Today we’re diving into three terms you’ll hear pretty often across all sectors… front end, back end and full stack development!
Front End Development: The Dining Area
Imagine you’re going out to eat at a restaurant. The dining area is designed just for you down to every detail. It’s comfy and well-lit with a relaxing ambiance. The waitstaff is friendly and ready to answer your questions. It’s a polished user experience. This is similar to what front end development is all about.
Front end developers work on everything you see and interact with on a website or app. They design the layout, choose the colors, and ensure that the buttons and links work as expected. They test and make sure everything is up to the standards of the customer.
Just like how a restaurant’s dining area is crafted to create a pleasant atmosphere and make your dining experience smooth, front end developers use languages like HTML, CSS, and JavaScript to create an engaging and user-friendly interface.
Back End Development: The Kitchen and Staff
Now, think about what happens behind the scenes in the restaurant’s kitchen. The chefs prepare the food, the kitchen staff manages the inventory, and the dishwashers clean up. There is an entire different workplace with its own systems and procedures going on back there just one wall away from you!
This is what back end development is like. Back end developers work on the server, database, and application logic that you don’t see directly. They ensure that when you place an order (like submitting a form or searching for information), it gets processed correctly and the right information is delivered back to you. This is back end development. Even though it’s all working to serve your need as the user, none of it is designed for your eyes.
Full Stack Development: The Restaurant Manager
This brings us to full stack. Let’s think about the restaurant manager. This person understands both the dining experience and the kitchen operations – and more importantly, how they work together. They ensure that everything runs smoothly. They troubleshoot problems in the front of the house where customers are all the way to the back of the house where food is prepared. They handle staff, manage inventory, and resolve any issues that arise. They are often the ones who have the best context to deal with issues that affect the entire pipeline from prep table to dining room table!
This is similar to what a full stack developer does. Full stack developers are skilled in both front end and back end development. They manage the entire web development process, ensuring that the user interface and the server-side functions (work seamlessly together. Just like a restaurant manager coordinates every aspect of the restaurant, a full stack developer oversees both the visual and functional aspects of a website or app.
Now You Have the Full Stack
That’s all for this DevSpeak. These aren’t huge concepts, but they’re important pieces to understand the language developers use. Hopefully these short summaries give you a little more context and confidence to take part in the greater conversations out there about technology! We don’t all start from the same knowledge level, but that doesn’t mean that we don’t all have valuable input!
