DevOps & Agile Implementation

DevOps & Agile Implementation :

DevOps is combination of philosophies and software engineering practices that unifies software development and operations by utilizing the tool and technology stacks to increase the organization ability to deliver applications/products at higher pace than customer’s expectation verses compared to traditional software engineering practice of working in silos leading to friction between various teams.

In recent times, Agile methodology, DevOps implementation and Cloud infrastructure have become the cornerstone for the success of companies where

  • Agile delivers on iteratively developed applications/products with faster ROI and reduced risks
  • DevOps ensured that continuously developed, built, tested and released product is automated, reliable and has shorter TTM (Time To Market)
  • Cloud offers pay-as-you-go approach and avoiding long procurement delays leading to continuous cycle of innovate, grow, fail fast and cheap, learn, re-align and then innovate again

Benefits of Implementing DevOps:

The main benefits of implementing DevOps are:

  • faster delivery of features via Continues Integration and Continues Delivery (CI/CD) practices
  • stable operating environments as issues are caught at the early stages as testing is integral part of build process
  • reduced risks due to continuous software delivery
  • faster resolution of problems due to automation of build, test and deployment of the artifacts
  • reduced dependency on individual and increased team collaboration
  • reduces cost and re-alignment of resources to critical problems
  • streamlined and optimized processes
  • offers greater visibility and traceability throughout the whole process

DevOps using AWS:

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

Few of the important services under DevOps are listed below:

  • AWS CodeStar – enables you to quickly develop, build and deploy applications on AWS using unified user interface. AWS CodeStar has project management dashboard that comes with integrated Atlassian JIRA software.
  • AWS CodeCommit – fully-managed source control service that hosts secure and highly scalable private Git repositories
  • AWS CodeBuild – fully managed build service that compiles source code, runs tests, and produces software packages that are ready to deploy. No need to provision, manage, and scale your own build servers
  • AWS CodeDeploy – automates code deployments to any instance, including Amazon EC2 instances and servers running on-premises
  • AWS CodePipeline – continuous integration and continuous delivery service for fast and reliable application and infrastructure updates. CodePipeline builds, tests, and deploys your code every time there is a code change, based on the release process models you define
  • AWS Cloud9 – cloud-based integrated development environment (IDE) that lets you write, run, and debug your code with just a browser

DevOps using Azure:

The set of Azure DevOps services offered works for any languages targeting any platform. These combined set of services are sufficient enough from conceptualizing the ideas to releasing the finished products. These set of Azure DevOps services are similar to AWS services, some of which are listed below:

  • Azure Boards – project management dashboards with features such as Kanban board, backlogs, team dashboard, reporting etc
  • Azure Repos – cloud hosted private GIT repos for collaborative development of the product across different teams
  • Azure Pipelines – rich cross-platform CI/CD system that works with any language, platform, and cloud. Connects to GitHub or any Git repository and easily configurable for continuous deployment
  • Azure Test Plans – easy management of test plan and test cases from web

DevOps using Google Cloud Platform:

Though Google is late entrant compared to AWS and Azure in offering cloud services, it catching up fast as alternative to AWS and Azure. Along with offering set of services related to Storage, Compute, Analytics, AI, etc they also offer set of services which help in implementing end-to-end DevOps implementations through their services listed below:

  • Google Cloud Deployment Manager – allows you to specify all the resources needed for your application in a declarative format using yaml (or Python, or Jinja2). This means that rather than painstakingly listing each step that will be required for a deployment, DevOps teams can tell Deployment Manager what a final deployment should look like and GCP will use the necessary tools and processes for you
  • GCP Cloud Console – provides detailed view of every detail of your DevOps in the cloud. Google Cloud Console helps you deploy, scale and diagnose production issues in a simple web-based interface
