Introduction

AWS CodeDeploy automates the deployment of code to Amazon EC2 instances. It allows you to quickly release new features, avoid downtime during deployment, and manage the complexity of updating your apps. AWS CodeDeploy automates deployments, removing the need for error-prone manual processes. The service scales with your infrastructure, allowing you to deploy to one or thousands of EC2 instances.

AWS CodeDeploy

CodeDeploy is an application deployment service for Amazon EC2 instances, on-premises instances, serverless Lambda functions, and Amazon ECS services.

AWS CodeDeploy is a fully managed software deployment tool that automates program deployments to Amazon EC2AWS Lambda, AWS Fargate, And your on-premises servers. AWS CodeDeploy again makes it easier to quickly deliver new features, reduce downtime during application deployment, and manage the complexity of application updates. AWS CodeDeploy allows you to automate software deployments, removing the need for error-prone manual processes. The service adapts to your deployment requirements.

Use of AWS CodeDeploy

AWS CodeDeploy makes it easier to quickly deliver new features. It automates application deployments to various computing services, reduces downtime during application deployment, and manages the complexity of application updates. AWS CodeDeploy allows you to automate software deployments, removing the need for error-prone manual processes.

CodeDeploy agent in AWS

The CodeDeploy agent is a piece of software that makes it easier to deploy to Amazon EC2, on-premises instances, and other virtual machines. Visit the CodeDeploy agent version history for additional information on this release. Visit the AWS global region table to see what's available in your area.

Benefits of Amazon CodeDeploy

  • Applications for servers, serverless, and containers: CodeDeploy allows you to deploy both traditional server-based apps and serverless Amazon Lambda function versions or Amazon ECS applications.
  • Reduce downtime: If your application runs on the EC2/On-Premises compute platform, CodeDeploy can help you get the most out of it. CodeDeploy performs a rolling update across Amazon EC2 instances during an in-place deployment. You can select the number of instances that will be taken offline for upgrades at a given time. The most recent application revision is installed on replacement instances during a blue/green deployment. When you choose, traffic is diverted to these instances either immediately or after you've finished testing the new environment. CodeDeploy tracks application health according to the rules you set up for both deployment methods.
  • Rollback and stop: If there are errors, you can stop and roll back deployments automatically or manually.
  • Control is centralized: You can use the CodeDeploy console or the Amazon CLI to launch and track your deployments. You'll get a report detailing when and to which Amazon EC2 instances each application revision was deployed.
  • Adoption is simple: CodeDeploy works with any application and is platform neutral. Your setup code can be readily reused. Your software release process or continuous delivery toolchain can also be integrated with CodeDeploy.
  • Continuous deployments: If you have many applications that use the EC2/On-Premises computing platform, CodeDeploy may deploy them all to the same set of instances at the same time.

CodeDeploy compute platforms

The CodeDeploy compute platforms are as follows:-

Amazon Lambda: Used to distribute Lambda functions that have been updated. The Lambda function is managed by Amazon Lambda in a serverless computing environment with a high-availability compute structure. Amazon Lambda is in charge of all computing resource administration. See Serverless Computing and Applications for further details. See Amazon Lambda for additional information on Lambda functions and Amazon Lambda. During a deployment, you can choose whether traffic is shifted to the updated Lambda function versions in a canary, linear, or all-at-once mode.

 

Amazon ECS: As a task set, an Amazon ECS containerized application is deployed. By deploying an updated version of the application as a new replacement task set, CodeDeploy executes a blue/green deployment. Production traffic is rerouted from the original application job assigned to the replacement task defined by CodeDeploy. After a successful deployment, the initial task set is ended. See Amazon Elastic Container Service for additional information on Amazon ECS. During a deployment, you can choose between a canary, linear, or all-at-once configuration to control how traffic is migrated to the new task set.

AWS CodeDeploy Features

  • It can be used to deploy traditional programs that require servers, as well as serverless apps and applications like Amazon ECS (container applications).
  • CodeDeploy is a fully managed, automated service that deploys user applications in development, test, and production environments automatically.
  • It may be used to deploy one or a thousand instances and is extremely scalable with the user infrastructure.
  • If your application employs an EC2 or on-premise compute platform, CodeDeploy can make it highly available. CodeDeploy does a rolling update across Amazon EC2 instances when an in-place deployment occurs. During the update, the number of instances that need to be taken down must be provided.
  • The CodeDeploy console or the AWS CLI can be used to track the status of each deployment made by the user. A report will be sent to the user detailing when each program was altered when it was deployed, and to which Amazon EC2 instance it was deployed.
  • If you have numerous applications that use the EC2 or on-premise compute platform, CodeDeploy can let you deploy them all at the same time to the same set of instances.
  • CodeDeploy is a simple to use and adaptable platform that can be used with any application. The setup code can be reused easily.

Types of applications that can be deployed with AWS CodeDeploy

Any sort of application can be deployed with AWS CodeDeploy. You define the files to copy and the scripts to run on each instance during the deployment with AWS CodeDeploy. Because AWS CodeDeploy is independent of programming languages and architecture, you can utilize scripts to implement any custom deployment logic.

Deployment of an application from an individual source control system using AWS CodeDeploy

Using GitHub, you can immediately deploy a revision from your repository to instances in.zip in.zip,.tar, or.tar.gz format. You can bundle and upload the revision to an Amazon S3 bucket in.zip,.tar, or.tar.gz format for other source control systems, then mention the Amazon S3 location when making a deployment. If your application requires a build step, ensure the post-build artifacts are stored in a GitHub repository or an Amazon S3 bucket. See our product integrations page for additional information on utilizing GitHub with AWS CodeDeploy. See Push a Revision for additional information on utilizing Amazon S3 to store revisions.

Working with a Configuration Management Tool

Any deployment lifecycle event hook in the AppSpec file can be used to call your configuration management solution. For example, if you wish to run a Chef recipe as part of a deployment, you can do so by providing it in the AppSpec file's appropriate deployment lifecycle event hook. You can also install the AWS CodeDeploy agent on instances using your configuration management system. See our product integrations page for examples of integrating AWS CodeDeploy with configuration management tools like Chef, Puppet, Ansible, and Saltstack.

AWS CodeDeploy works with Auto Scaling

To ensure that freshly created instances always obtain the latest version of your application, you can associate an Auto Scaling group with a deployment group. When a new Amazon EC2 instance for that Auto Scaling group is launched, it will initially be placed in a Pending state, with the last successful revision for that deployment group being deployed on that Amazon EC2 instance. The Amazon EC2 instance's state is updated to InService if the deployment is successful. If the deployment fails, the Amazon EC2 instance is terminated, a new Amazon EC2 instance is created in the Pending state, and deployment for the newly created EC2 instance is triggered.
