What is Amazon ECS?
Answer
AWS Docs: "Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service. Customers such as Duolingo, Samsung, GE, and Cook Pad use ECS to run their most sensitive and mission critical applications because of its security, reliability, and scalability."
In simpler words, it allows you to launch containers on AWS.
While AWS takes care of starting/stopping containers, you need to provision and maintain the infrastructure where the containers are running (EC2 instances).
