Automation and Orchestration in AWS

In this article, we’ll explore AWS services designed for Automation and Orchestration.

Automation is often associated with DevOps, particularly in the context of CI/CD pipelines. But what exactly does CI/CD mean?

• CI (Continuous Integration): The practice of frequently integrating or merging small code changes to a shared repository, ensuring consistency and reducing integration issues.
• CD (Continuous Deployment): Automates the processes of building, testing, and deploying code, enabling faster and more reliable software delivery.

Benefits of CI/CD:

• Automates processes to enhance agility, ensure consistency, and support scalability.
• Reduces the need for manual effort, streamlining workflows.
• Facilitates frequent application of small code changes, making it easier to identify and fix bugs early in the development cycle.

Example workflow for CI/CD:

AWS Services for CI/CD

AWS CodeCommit: A centralized code repository, similar to a private Git repository in the cloud. It stores source code, binaries, images, and software libraries, enabling collaboration by managing updates from multiple sources. With version history, teams can easily track and manage changes.

AWS CodeBuild: A fully managed build and test service that runs predefined commands to compile code, execute tests, and generate build artifacts.

AWS CodeDeploy: An automated deployment service that simplifies deploying software to EC2 instances, on-premise servers, and Lambda. It supports frequent feature releases, minimizes downtime, and reduces risks associated with manual deployments.

AWS CodePipeline: A service that automates the workflow of CI/CD pipelines, orchestrating the entire process. It triggers the pipeline whenever code changes are detected, ensuring fast and consistent releases. It integrates seamlessly with services like CodeCommit, CodeBuild, and CodeDeploy.

AWS Development Tools

AWS CloudShell: A browser-based shell environment with the AWS CLI pre-installed, enabling quick and convenient management of AWS services directly from your browser.

• AWS CLI: A command-line tool for managing AWS services. It can also be installed locally on your computer.
  • Command reference link: https://docs.aws.amazon.com/cli/latest/

AWS Cloud9: A browser-based Integrated Development Environment (IDE) that allows developers to write, run, and debug code. It comes with pre-installed tools like the AWS CLI and supports popular programming languages such as JavaScript, Python, Ruby, and C++.

A central artifact repository for securely storing, publishing, and sharing software packages during the development process (e.g. Python, npm). It simplifies access to necessary packages, supports open-source, third-party, and in-house software, and helps standardize software versions used by developers. It can also serve as a repository for company-approved packages.

Orchestration and Infrastructure as Code in AWS

AWS Step Functions: a service used to manage the distributed logic of applications made up of multiple components. It enables you to build and run serverless applications as a series of defined steps.

• Features:
  • Visualization: Provides a visual interface to design and monitor serverless application workflows.
  • Automation: Automatically triggers and tracks the execution of each step in the workflow.
  • Logging: Logs the state of each step, making it easy to debug and identify issues.
  • Sequential Execution: Ensures that each step executes in the order defined by your business logic.
  • Error Handling: Offers built-in error-handling mechanisms to manage exceptions during workflow execution.
  • Parallel Processing: Supports workflows with parallel steps to handle complex processes efficiently. Example workflow:

AWS Infrastructure as Code with CloudFormation

CloudFormation is an AWS service that allows you to manage and provision AWS infrastructure using an Infrastructure as Code (IaC) approach.

• Key Features:
  • Enables deployment of AWS resources through code-based templates.
  • Facilitates the management, configuration, and provisioning of infrastructure as code.
  • Resources are defined in CloudFormation templates written in YAML or JSON.
  • CloudFormation interprets these templates and makes the necessary API calls to create the specified resources.
  • The resources created from a template are collectively referred to as a CloudFormation Stack.
• Benefits:
  • Consistency: Ensures infrastructure is provisioned uniformly, reducing the risk of errors.
  • Efficiency: Speeds up deployment and reduces manual configuration effort.
  • Cost-Effective: CloudFormation itself is free; you only pay for the AWS resources provisioned through it.

AWS Elastic Beanstalk:

• a service that simplifies application deployment by managing the underlying infrastructure for you.
• Key Features:
  • Developers simply upload their code, and Elastic Beanstalk provisions the required AWS infrastructure to run the application.
  • Handles capacity provisioning, auto-scaling, and health monitoring using CloudWatch.
  • Allows developers to focus on writing code without worrying about infrastructure configuration.
  • Accelerates application deployment, helping you get to market faster.
  • Provides the fastest and simplest way to deploy applications on AWS.
  • Supports multiple programming languages and platforms, including Java, .NET, PHP, Node.js, Python, Ruby, Go, and application server platforms like Apache, Tomcat, IIS, Nginx, and Docker.
  • Includes operating system and application server updates, along with built-in monitoring and health checks. Example Scenario:
