Amazon Fargate Quick Start Guide

By: Deepak Vohra

Overview of this book

Amazon Fargate is new launch type for the Amazon Elastic Container Service (ECS). ECS is an AWS service for Docker container orchestration. Docker is the de facto containerization framework and has revolutionized packaging and deployment of software. The introduction of Fargate has made the ECS platform serverless. The book takes you through how Amazon Fargate runs ECS services composed of tasks and Docker containers and exposes the containers to the user. Fargate has simplified the ECS platform. We will learn how Fargate creates an Elastic Network Interface (ENI) for each task and how auto scaling can be enabled for ECS tasks. You will also learn about using an IAM policy to download Docker images and send logs to CloudWatch. Finally, by the end of this book, you will have learned about how to use ECS CLI to create an ECS cluster and deploy tasks with Docker Compose.

Demonstrating the use of auto scaling

In this section, we shall demonstrate the use of auto scaling by adding an extra load to the Hello world service. 

  • Invoke the service using the public IP of one of the tasks; the public IP may be obtained from a task's details, as shown in the following screenshot:
  • First, invoke the service in one browser only. The Hello world application gets invoked and the service response gets displayed in the browser, as shown in the following screenshot:
  • To increase the load, invoke the same Hello world application multiple times using the curl tool. Run the following command on a Windows Command line:
  • An internal load balancer automatically distributes the client load among the tasks in a service, regardless of which task is invoked by a client. An external load balancer may also be configured, as discussed in a later chapter. As the client load on the Hello world service is increased, the number of tasks also gets increased...
