Summary

In this chapter, you learned about serverless applications and architecture, the benefits and use cases, and the limits to using the serverless approach. It is important to understand the serverless architecture and what it encompasses before designing an application that relies on it. Serverless computing is an event-driven, FaaS technology that utilizes third-party technology and servers to remove the problem of having to build and maintain infrastructure to create an application.

Serverless computing may not be the right approach for every problem that is out there, so be cautious if anyone says that serverless computing will replace all of your existing application architectures. Serverless computing might be the answer for the new architectures that you are building now and it may very well replace your existing architectures but there are drawbacks as well to serverless computing, so keep those in mind when you design your serverless application architecture. As the tooling around serverless computing improves in the coming years, you will see that these drawbacks will become a thing of the past. 

The benefits that serverless computing provides are significant. They include reduced operational costs, and rapid development, and deployment of your serverless applications. Other benefits include easier operational management and reduced environmental impact through better utilization of compute infrastructures.

The next chapter will discuss the tools and a programming language that is required to write your Serverless applications. It will introduce the different SDKs that AWS, Microsoft Azure, and Google Cloud offer to write serverless applications.
