Processes to set up your AWS account

At first, visit the AWS Management Console to create an AWS account and complete the registration process. Then, set up an IAM (Identity and Access Management) user to assign permissions and securely access AWS resources.

Key AWS DevOps tools and their features 

AWS provides a comprehensive suite of DevOps tools, each of which serves a specific purpose. These tools are as follows-

a). AWS Code Commit – This is a powerful platform to manage source code in a collaborative, secure, and scalable manner. With this fully managed source control service, teams can host secure and private Git repositories. Some of the key features of this tool are as follows – a) scalability, b) collaboration, c) integration with other AWS services, d) high availability, and e) security.  

b). AWS CodeBuild – This service considers tasks like compiling source code, running tests, and packaging software for deployment. The capacity of this tool can be easily adjusted and thereby it offers support to multiple programming languages and custom build environments. Apart from easily tracking build status and receiving notifications, this tool enhances the entire process making it more efficient and reliable.

c). AWS CodeDeploy – By simplifying application deployment across different services like Amazon EC2, AWS Lambda, and on-premise servers, it seamlessly integrates with CI/CD tools. Also, this tool reduces the downtime due to automatic deployment, which minimizes the chance of errors. Other features of this tool are efficient handling of the management console and effective monitoring of deployment. 

d). AWS Code Pipeline – The service of this tool makes the steps of the release process efficient whenever the code changes happen. By integrating with other services, it offers the features of seamless workflow through planning and visualizing the flow of the software. By providing the options of various parallel plugins and custom plugins, it easily enhances the workflow speed. Further, CodePipeline acts as its own source agent and offers declarative templates for easy updates and the creation of new pipelines. 

e). AWS CloudFormation – This tool helps to design and deploy the AWS resources through templates. By using the option of infrastructure as code, it ensures version control. Apart from streamlining the process of setting up and modifying the infrastructure securely and consistently, it delivers a complete infrastructure as a code solution. The CloudFormation treats the entire infrastructure as code, to maintain uniformity and minimize human mistakes. Besides, extensibility and stack management, this tool provides support for various AWS resources and integrates with other AWS services to deliver a complete infrastructure as a code solution.

f). Amazon ECS – Amazon Elastic Container Service (ECS) is a fully managed container orchestration service, to easily deploy, manage, and scale containerized applications. By integrating with the AWS environment, ECS provides easy solutions to run container workloads in the cloud and on-premises with advanced security features. Also, it is a robust platform to maximize the power of the AWS cloud and offer integration with AWS services for simplifying management practices and enhancing cost-efficiency and scalability.

Process to implement CI/CD on AWS

The implementation of CI/CD on AWS needs to integrate services like CodeCommit, CodeBuild, CodeDeploy, and CodePipeline. Hence, the following set-up process needs to be adhered to maximize the effectiveness –

a). Source Stage – CodeCommit or GitHub must be used as the source of the pipeline.

b). Build Stage – Configuration of CodeBuild is necessary for compiling, testing, and packaging the application.

c). Deploy Stage – Automate deployment to EC2 instances, Lambda functions, or on-premises servers by using CodeDeploy.

d). Automate Pipeline – Triggers must be set up in CodePipeline to automatically start the pipeline upon code changes.
