What is AWS Fargate?

AWS Fargate was developed as an alternative to EC2 to provide a serverless, container-native compute solution with three key design tenets:

To be as secure as possible
To be reliable and scale to meet demand
To be cost-efficient

If we compare the EC2-based EKS worker node and Fargate technical stacks, illustrated in Figure 15.1, we can see that they are very similar. They run on physical servers, with both a virtual machine operating system and a container runtime that support a containerized application. The key difference is that Fargate is serverless, which means that you don’t need to care about the virtual machine operating system, container runtime, and so on, as this is all managed by AWS:

Figure 15.1 – AWS Fargate versus EC2

The other main difference is that Fargate is really designed for small, bursty, or batch workloads, unlike EC2, which is traditionally used for more stable, long-running...
