Introduction

Imagine that a critical application in your company is having performance issues. This application is available to customers 24-7, and during business hours, the CPU and memory utilization reaches 100%. This is resulting in an increased response time for customers.

Around 10 years ago, a good migration plan to solve this issue would involve the procurement and deployment of new hardware resources for both the application and its databases, the installation of all required software and application code, performing all functional and performance quality analysis work, and finally, migrating the application. The cost of this would run into millions. However, nowadays, this issue can be resolved with new technologies that offer different approaches to customers – going Serverless is definitely one of them.

In this chapter, we'll start with an explanation of the serverless model, and get started with AWS and Lambda, the building blocks of a serverless applications on AWS. Finally, you'll learn how to create and run Lambda functions.
