So finally, we are at the end of the first chapter of this book.

In this chapter, we have discussed serverless architecture with the evolution of cloud computing. We covered the definition of cloud computing, cloud service models, cloud deployment models, and so on.

We discussed in detail about IaaS and PaaS and how they have matured and how the use cases have changed and why. We touched upon serverless computing and its visible benefits as an evolution.

We also discussed in detail Azure Function, saw an overview of how the function is executed in a free trial, and got a basic understanding of the Microsoft Azure platform.

In the last section of this chapter, we covered some of the differences between Web App AWS Lambda and Azure Functions.

In the next chapter, we will discuss Azure Functions, its architecture, and other details and we will create our first function in the Microsoft Azure subscription.
