Your team has been instructed to deploy a Microservices and an ETL based application onto AWS. There is a requirement to manage the containerization of the application using Docker. Which of the following would the ideal way to implement this with the least amount of administrative effort?

Answer options:

A.Use AWS OpsWorks
B.Use the Elastic Container Service.
C.Deploy Kubernetes on EC2 Instances.
D.Use the CloudFormation service.

Answer – B
The Elastic Container Service is a fully managed container orchestration service available in AWS.
The AWS Documentation mentions the following.
Amazon Elastic Container Service (Amazon ECS) is a highly scalable, high-performance container orchestration service that supports Docker containers. It allows you to run and scale containerized applications on AWS easily. Amazon ECS eliminates the need for you to install and operate your own container orchestration software, manage and scale a cluster of virtual machines, or schedule containers on those virtual machines.
Option A is incorrect because AWS OpsWorks helps to configure and operate applications in a cloud enterprise by using Puppet or Chef, which is not required in the question.
Option C is incorrect since even though Kubernetes is a fully managed solution, hosting it on EC2 Instances will incur more administrative headache.
Option D is incorrect because AWS CloudFormation is a service that helps you model and set up your Amazon Web Services resources. But it does not manage the Docker containers like ECS.

The following diagram illustrates an architectural implementation of microservices on AWS.
The API of a microservice is the central entry point for all client requests. The application logic hides behind a set of programmatic interfaces, typically a RESTful web services API. This API accepts and processes calls from clients and might implement functionality such as traffic management, request filtering, routing, caching, and authentication and authorization.
Many AWS customers use the Elastic Load Balancing (ELB) Application Load Balancer together with Amazon EC2 Container Service (Amazon ECS) and Auto Scaling to implement a microservices application. The Application Load Balancer routes traffic based on advanced application-level information that includes the content of the request.
