Q

Continuous delivery

A

a software development practice whereby code changes are automatically built, tested, and prepared for a release to production. It expands upon continuous integration by deploying all code changes to a testing environment, production environment, or both after the build stage

Q

Continuous Delivery (CD) Best Practices

A

When the following CD best practices are applied, software can be released to production at any time.

  • Code changes are committed to the repository and built frequently (versioned sourced).
  • Builds are deployed to test environments and tested using automated and possibly manual tests.
  • Builds that pass rigorous tests are rapidly deployed to staging or production environments. A robust continuous delivery pipeline also does the following:
  • Automates the provisioning of infrastructure for testing and production environments
  • Enables the monitoring and management of test and production environments.

Q

What AWS service can be used for Version Control?

A

AWS CodeCommit

Like bitbucket or github

is a managed source control system that hosts Git repositories and works with all Git-based tools. AWS CodeCommit stores code, binaries, and metadata in a redundant fashion with high availability. You will be able to collaborate with local and remote teams to edit, compare, sync, and revise your code.

19
Q

What is AWS CodePipeline?

A

AWS CodePipeline is a fully managed continuous delivery service that helps you automate your release pipelines for fast and reliable application and infrastructure updates.

CodePipeline automates the build, test, and deploy phases of your release process every time there is a code change, based on the release model you define. This enables you to rapidly and reliably deliver features and updates. You can easily integrate AWS CodePipeline with third-party services such as GitHub or with your own custom plugin. With AWS CodePipeline, you only pay for what you use. There are no upfront fees or long-term commitments.

20
Q

What is AWS CodeBuild?

A

AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages.

Its benefits are:

  • Scales continously and processes multiply builds concurrently
  • No build servers to manage
  • Monitor builds through CloudWatch Events
21
Q

What is AWS CodeDeploy?

A

AWS CodeDeploy is a fully managed deployment service that automates software deployments to a variety of compute services, such as Amazon EC2, AWS Fargate, AWS Lambda, and your on-premises servers.

AWS CodeDeploy makes it easier for you to rapidly release new features, helps you avoid downtime during application deployment, and handles the complexity of updating your applications.

22
Q

What is AWS CodeStar?

A

Enables you to quickly set up a continuous delivery toolchain for your application and start releasing code faster on AWS. AWS CodeStar provides a unified experience that enables you to easily build, test, and deploy applications to AWS with the help of AWS CodeCommit, AWS CodeBuild, AWS CodePipeline, and AWS CodeDeploy.
