Overview of this book

Expert AWS Development begins with the installation of the AWS SDK and you will go on to get hands-on experience of creating an application using the AWS Management Console and the AWS Command Line Interface (CLI). Then, you will integrate applications with AWS services such as DynamoDB, Amazon Kinesis, AWS Lambda, Amazon SQS, and Amazon SWF. Following this, you will get well versed with CI/CD workflow and work with four major phases in the release process – Source, Build, Test, and Production. Then, you will learn to apply AWS Developer tools to your Continuous Integration (CI) and Continuous Deployment (CD) workflow. Later, you will learn about user authentication using Amazon Cognito, and also how you can evaluate the best architecture as per your infrastructure costs. You will learn about Amazon EC2 service and will deploy an app using it. You will also deploy a practical real-world example of a CI/CD application with the Serverless Application Framework, which is known as AWS Lambda. Finally, you will learn how to build, develop, and deploy the Application using AWS Developer tools such as AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline, as per your project requirements.

Amazon ECS clusters


An Amazon ECS cluster is a logical group that contains tasks or services. If your task or service uses the EC2 launch type then the cluster is a grouping of container instances. The first time, Amazon ECS will create a default cluster for you. To keep your resources separate, you can create multiple clusters.

We will look at the following in relation to Amazon ECS clusters:

  • Cluster concepts
  • Creating a cluster
  • Scaling a cluster
  • Deleting a cluster

Cluster concepts

  • Clusters are region-specific and contain tasks using Fargate or EC2 launch types
  • IAM policies are used to allow or restrict users from accessing your clusters
  • With EC2 launch type, your cluster can contain different container instance types; this container instance type will be part of one cluster at a time

Creating a cluster

You can create the cluster using AWS Management Console by performing the following steps. If you use the EC2 launch type to launch the task, you should register your container instance with the cluster...
