AWS ECS

What is ECS?

ECS is Amazon their own take to make a container orchestrator, before surrendering to Kubernetes (therefore, [[AWS EKS]])

Components

• Task definition: define a job that will be run on the container(s), define also the container(s) resources. One task definition can create several tasks
• Task: is an instance of a task definition.
• Service: how many tasks you want to run for how long (at least this is my understanding)

Pricing

Traditional ECS under the hood provisions EC2 instances to build a cluster, where the user pays for the EC2 instances.

Fargate is the “Serverless” version of the above where the user pays for the time of running.
