Are you a developer trying to understand how serverless architecture works? Find out how in this guide.

If you’ve heard of “serverless architecture,” but you’re still confused about what it means, don’t worry. This concept has been growing in popularity within the past few years, and it doesn’t look like its slowing down. Now, more and more cloud computing companies are trying to use serverless computing for their business.

Whether it’s you’re starting to program, or you’re a programming professional, you’re going to use serverless architecture to help create high-quality apps. And in this guide, we want to help you see why you should start using it today.

What is Serverless Computing?

Serverless computing is when developers use cloud-based servers, operating systems, and infrastructures. Even though it’s called “serverless computing,” there are servers involved. But the managed service, capacity planning, server management, and setup are invisible because they’re handled by the cloud provider.

In traditional environments, developers must create and configure servers and manage the entire infrastructure. With serverless computing, you can develop, deploy, and manage apps that can scale with demand — without having to worry about the infrastructure.

Serverless computing architecture is highly-scalable, event-driven, and uses resources when a specific function occurs. This means you can pay for resources or the time used to keep the server running.

Here are some of the benefits you’ll experience when building a serverless architecture.

Provides Flexibility

You can easily implement an app when it’s serverless in comparison to traditional methods. Going serverless allows you to innovate faster and complete projects faster. When you can see the results immediately, you can get to the next project.

You can start making the next microservice or app feature. Serverless architecture gives you the benefit once you’re not bounded by constraints. This helps you pivot in situations where you’ll need to restructure your app.

Improved Customer Experience

This will depend on the company, but serverless architecture can lead to more satisfied customers. A company can make more improved servers meaning that customers will access the new features faster.

No one wants to wait a year for minor fixes. You can release the features and logic quickly, which can help improve the user experience.

Improved Security

By having the developer use only code constructs in a serverless context, then the developer will make code that conforms with the company’s best practices, and it works with governance and security protocols.

Power Separations

The objective of serverless computing is to increase the developer’s productivity by helping with bootstrapping, housekeeping, and the dependencies in the background.

This way, the developer can concentrate on the important functions he’s trying to provide. This helps him think more objectively, thus making the code in an object-oriented platform, making it easier to divide it into compartments, scale up and down, and then subdivide into discrete functions.


In the end, serverless architecture can be used to help deploy apps faster, enhance customer experience, and it allows you to take the scale your apps based on demand. Make sure to train your IT team so that they can become experienced at utilizing it to your advantage. By doing this, you’ll find it easier to complete projects within a reasonable time frame.
