As we moved through this chapter, we took a look at how the serverless architecture is becoming the new trend in the development of the applications, and how this architecture works. We covered the different components of the serverless architecture and went through the concepts of Backend as a Service and Function as a Service, which power the serverless architecture. We then looked at the role of API Gateways in the architecture and how the API Gateway in serverless applications differs from the one we used in Microservices.
After that, we took a tour of building our first serverless application and ran it through Apache OpenWhisk, which provides an open source platform for running serverless applications. Here, we also took a deep dive into how the different components inside the OpenWhisk project work together to get the final results to us.
We concluded the chapter...
