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.

Scheduling tasks


The Amazon ECS is an optimistic concurrency system in a shared state with elastic scheduling capabilities for containers and tasks. Amazon ECS uses Amazon ECS API's same state information for clusters to make appropriate decisions for placement. Amazon ECS has the ability to manually run tasks (for single run task or batch jobs) or service schedulers (for long-running tasks), where it places the task on the cluster for you. It allows you to define constraints and a task placement strategy, to run the task in the configuration you have selected, such as spread out in Availability Zones. You can also integrate with third-party or custom schedulers.

We can divide this section into the following topics:

  • Service scheduler
  • Manually running tasks
  • Running tasks on a cron-like schedule
  • Custom schedulers
  • Task life cycle
  • Task retirement

Service scheduler

The service scheduler is best suited for applications and long running services that are stateless. It will ensure that the stated numbers...
