AWS Developer Tools

AWS Developer Tools

  • AWS Developer Tools provide a set of services designed to enable developers and IT operations professionals practicing DevOps to rapidly and safely deliver software.
  • AWS Developer Tools help securely store and version control the application’s source code and automatically build, test, and deploy the application to AWS or the on-premises environment.

AWS DevOps Tools

AWS CodeCommit

  • CodeCommit is a secure, scalable, fully-managed source control service that helps to host secure and highly scalable private Git repositories.
  • eliminates the need to operate your own source control system or worry about scaling its infrastructure.
  • can be used to securely store anything from source code to binaries, and it works seamlessly with your existing Git tools.
  • provide high availability as it is built on highly scalable, redundant, and durable AWS services such as S3 and DynamoDB.
  • is designed for collaborative software development and it manages batches of changes across multiple files, offers parallel branching, and includes version differencing.
  • automatically encrypts the files in transit and at rest.
  • is integrated with AWS Identity and Access Management (IAM), allowing you to assign user-specific permissions to your repositories.
  • supports resource-level permissions at the repository level. Permissions can specify which users can perform which actions including MFA.
  • supports HTTPS or SSH or both communication protocols.
  • supports repository triggers, to send notifications and create HTTP webhooks with SNS or invoke Lambda functions.

AWS CodeBuild

  • AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages that are ready to deploy.
  • helps provision, manage, and scale the build servers.
  • scales continuously and processes multiple builds concurrently, so the builds are not left waiting in a queue.
  • provides prepackaged build environments or the creation of custom build environments that use your own build tools.
  • supports AWS CodeCommit, S3, GitHub, and GitHub Enterprise and Bitbucket to pull source code for builds.
  • provides security and separation at the infrastructure and execution levels
  • runs the build in fresh environments isolated from other users and discards each build environment upon completion.

AWS CodeDeploy

  • AWS CodeDeploy helps automate code deployments to any instance, including EC2 instances and instances running on-premises.
  • helps to rapidly release new features, avoid downtime during application deployment, and handles the complexity of updating the applications.
  • helps automate software deployments, eliminating the need for error-prone manual operations.
  • scales with the infrastructure and can be used to easily deploy from one instance or thousands.
  • performs a deployment with the following parameters
    • Revision – what to deploy
    • Deployment group – where to deploy
    • Deployment configuration – how to deploy
  • Deployment group is an entity for grouping EC2 instances or Lambda functions in deployment and supports instances by specifying a tag, an Auto Scaling group.
  • AppSpec file provides the instructions and is a configuration file that specifies the files to be copied and scripts to be executed.
  • supports both in-place deployments, where rolling updates are performed, and blue/green deployments.

AWS CodePipeline

  • AWS CodePipeline is a fully managed continuous delivery service that helps automate the release pipelines for fast and reliable application and infrastructure updates.
  • automates the builds, tests, and deploys the code every time there is a code change, based on the defined release process models
  • enables rapid and reliable delivery of features and updates.
  • can be integrated with third-party services such as GitHub or with your own custom plugin.
  • pay per use with no upfront fees or long-term commitments.
  • supports resource-level permissions. Permissions can specify which users can perform what action on a pipeline.
  • CodePipeline concepts

CodePipeline Concepts

  • A Pipeline describes how software changes go through a release process
  • A revision is a change made to the source location defined for the pipeline.
  • Pipeline is a sequence of stages and actions.
  • A stage is a group of one or more actions. A pipeline can have two or more stages.
  • An action is a task performed on a revision.
  • Pipeline actions occur in a specified order, in serial or in parallel, as determined in the stage configuration.
  • Stages are connected by transitions
  • Transitions can be disabled or enabled between stages.


  • A pipeline can have multiple revisions flowing through it at the same time.
  • Action acts upon a file or set of files are called artifacts. These artifacts can be worked upon by later actions in the pipeline.

AWS CodeArtifact

  • AWS CodeArtifact is a fully managed artifact repository service that makes it easy for organizations of any size to securely store, publish, and share software packages used in their software development process.
  • CodeArtifact can be configured to automatically fetch software packages and dependencies from public artifact repositories so developers have access to the latest versions.
  • CodeArtifact works with commonly used package managers and build tools like Maven, Gradle, npm, yarn, twine, pip, and NuGet making it easy to integrate into existing development workflows.

AWS Certification Exam Practice Questions

  • Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
  • AWS services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
  • AWS exam questions are not updated to keep up the pace with AWS updates, so even if the underlying feature has changed the question might not be updated
  • Open to further feedback, discussion and correction.
