Public cloud offerings

Before we delve into the core subject of this book and start working with Kubernetes, we should have a look at the alternatives; after all, the services we are going to be covering in upcoming chapters are nearly all loosely based off these services.

The three main public cloud providers all provide a serverless service:

• AWS Lambda from AWS (https://aws.amazon.com/lambda/)
• Azure Functions by Microsoft (https://azure.microsoft.com/en-gb/services/functions/)
• Cloud Functions from Google (https://cloud.google.com/functions/)

Each of these services has the support of several different code frameworks. For the purposes of this book, we will not be looking at the code frameworks in too much detail as using these is a design decision which has to based on your code.

We are going to be looking at two of these services, Lambda from AWS and Functions by Microsoft Azure.
