How Serverless Web Applications are Changing the Development Landscape


Serverless computing is the future of the development landscape. Know how this next version of cloud computing is changing the gaming field of web development and how it affects you.

Serverless is the next evolution in cloud computing. It's a framework that allows developers to focus on the business logic of their applications instead of worrying about infrastructure management. It also lets them use the language and tools they prefer, even if those choices aren't what everyone else uses. Today, we'll discuss why serverless web applications are changing the development landscape and how serverless is a game-changer for developers.

Why Serverless?


Serverless is the future of web applications. It offers a more efficient and cost-effective way to build, deploy and manage applications while also enabling developers to focus on building functionality rather than managing infrastructure.

The answer is simple for those wondering what's behind the hype: cloud-native application development. Cloud-nimble is the next stage of cloud-native development, and it's being driven by the emergence of serverless platforms such as JFrog.

The benefits of serverless include:
  • Reduced Costs - You only pay for the resources used by your application; there are no upfront costs or long-term contracts.
  • Increased Agility - Serverless provides a dynamic environment where you can quickly scale your application up or down based on demand, making it easier to respond to changes in business needs or user behavior. This means faster time to market for new features!
  • Improved Security - Serverless environments are more secure than traditional cloud-native applications because they are based on microservices architectures and use containerized application components.

Challenges that come along with serverless include:
  • Lack of Control Over Performance - The lack of control over performance can lead to an underperforming system due to poor resource allocation decisions by cloud providers (e.g., lack of sufficient CPU capacity). However, this limitation can be mitigated if you choose an underlying framework/platform wisely!

  • Not Always Cost-Effective - It's important to note that serverless isn't always cost-effective. In many cases, it will be more expensive than traditional approaches such as AWS Lambda because it requires developers to write functions for every operation their application performs (e.g., add a user).

Different Services, Different Purposes, and Different Programming Languages


Serverless is a new way of building applications, but it's not a new programming language. It's not a new framework; it doesn't use Node, Scala, or Elixir for the backend. Serverless does not rely on databases such as MySQL or MongoDB; instead, it uses NoSQL databases like DynamoDB and S3. And finally, serverless is also not an operating system: you still need one to run your serverless code (e.g., AWS Lambda).

Even though some services provide some kind of abstraction between developers and infrastructure resources (like AWS Lambda), they don't hide all complexity from the developer—you still need to think about scaling problems, security concerns like user authentication, etc.

Modularity Encourages Collaboration and Contribution


With the rise of front-end frameworks such as React, Angular, and Vue, modularity has become a key concept in modern application development. This notion that all components live independently and can be easily combined to form a more extensive system is crucial for serverless applications.

This approach enables developers to share code among different projects on the web platform, thereby increasing efficiency and making it easier for more people to collaborate on building a single product or service. Many organizations are now choosing to rewrite their entire stack from scratch in this new way - from serverless microservices running on Kubernetes all the way down through their front end.

Release Management


Since serverless applications are typically built from microservices, it's essential to understand how each service is being deployed clearly.

You need to be able to test your changes and make sure they are working as expected before deploying them to production.

Additionally, you should ensure that only certain users see the new release or even just certain parts of the new release.

Most Challenges are Simple Inference, Not Complex Logic


The main challenge in serverless applications is to get the data in and out of the system. This can be done using adapters or cloud functions, which provide some infrastructure to process data outside the application.

The main benefit from a developer's perspective is that you don't need to worry about how your application works when there are no servers running it. You just deploy it, and then it will run on demand whenever someone visits your website or clicks on an ad, for instance—and all this without additional effort!

Conclusion


The future of serverless applications is still a little bit uncertain. The technology has yet to reach mainstream adoption, and it's still being developed as we speak. However, the potential is certainly there, and it's an auspicious approach to building web applications.
