Serverless has been expected to be a trend for some time and become more important for companies of all sizes and segments. 

The term describes an emerging software architecture where applications are hosted on the public cloud in order to make it easier for developers to compose the code intended to run.

In the future, Serverless could become so central that companies will no longer have to worry about infrastructure as the entire lifecycle will depend on cloud service providers.

We want to help you reflect on this.

Check out what the experts say about serverless architecture and how it will keep evolving!

Serverless: What is it anyway?

First, it is essential that we define what a Serverless architecture means and implies.

Broadly speaking, we can define Serverless as the maintenance of any application on a self-sufficient platform with built-in dependencies. In this model, customers don't have to worry about machine resources.

In addition, it is a software development pattern with no direct interaction with the server. 

However, serverless does not mean that applications run exactly without a server. 

On the contrary, the third-party cloud server is used to host the applications. Therefore, there is no need to manage server hardware and software to host the application. 

Basically, the hosting provider is responsible for the infrastructure and operational tasks. This means that developers of serverless applications are not concerned with capacity planning, configuration, maintenance, sizing the container, virtual machine, and physical server.

Why the Serverless Model is on the Rise

Serverless is a model where you don't have to manage any infrastructure, but your host will do it all for you.

Plus, you get the power to run and run anything you need, whenever you need it, on a level and following the best practices. That is, you assign the task of execution and the provider does the rest of the resource allocation, construction, execution, returning a status, and finally deallocating the resource.

It is also interesting to highlight the importance of serverless computing. 

In fact, if you only have software that you want to run in the cloud in reaction to some external event and you don't want to worry about provisioning and maintaining servers or containers, you can take advantage of it. 

In practice, you will have to adhere to a specific way of writing and deploying your code, but the cloud service provider will provide the infrastructure to run it without your intervention and release it after the code is complete.

Two types of services served by the Serverless architecture

See these two types of services that the serverless architecture serves:

In this case, developers don't care about the hosting environment. 

→ Y AWS Lambda is a popular service in this regard. 

Backend as a Service features are: notification, user management, authentication, scalable database and API.

→ A famous example is the AWS Amplify

Summing it Up

Why use a serverless architecture?

After the challenges faced by companies during the most critical period of the pandemic, it is interesting to ask yourself what Serverless architecture can bring to a business and why use it.

In serverless architecture, you simply need to deploy the applications on one platform and the platform will take care of all the dependencies. So it's easy to handle, scale and roll any application.

By using a serverless architecture, companies are able to keep their application efficiency high, while rapidly scaling their services and increasing their customers and productivity.

Also, Serverless can be used on many hosts like AWS Lambda. So serverless architecture is very useful as organizations don't need any architectural overhead while still running the necessary code.

What's more: it's economical; most hosts will only charge for runtime. So instead of paying for servers that are there charging you money, you can reduce the cost of your app just when it needs to run. For example, if you have a small and medium business website that doesn't have insane traffic, you can run it for a few hundred dollars a month.
