I – Basics of DevOps

DevOps Tools

To implement DevOps and work within the DevOps life cycle, following
tools
required

1. Code:
   For Source-Code Management (SCM) ,version control tools such as Git,
   GitHub, Subversion, TFS, and Mercurial are used.
2. Build:
   For automating the build process of an executable application from
   source code, software build tools such as Maven, Gradle, Ant, and
   Grunt are used.
3. Test:
   In the continuous testing phase, the built software is continuously
   tested for bugs using testing tools such as Selenium, TestNG, and
   JUnit.
4. Release:
   CI/CD pipelines are created for procuring updated source code and
   constructing the build into .exe format using tools such as Jenkins.
5. Operate:
   For deployment and operations phase, CMT and automation tools such as
   Jenkins, AWS CodeDeploy, Chef, Puppet, Ansible, and Terraform are
   used.
6. Monitor:
   For monitoring system performance and productivity, to reduce (or even
   eliminate) downtime, monitoring tools such as Nagios are used.
7. Deploy:
   For packaging an application with its required libraries, frameworks,
   and configuration files to efficiently run it in various computing
   environments, containerization tools such as Docker and Kubernetes are
   used.

Key Takeaways

• DevOps is a set of practices and tools designed to shorten the life
  cycle of a
  software development process
• Networking and cost-related issues, tools and software compatibility,
  and DevOps
  culture are a few challenges in traditional SDLC approach
• Agile is an iterative development procedure that promotes constant
  iteration of development and testing all over the life cycle of a
  project.
• Saas, PaaS, and IaaS are the three models of cloud computing services
  which help
  to implement DevOps in the cloud.
• Continuous development, continuous testing, continuous integration,
  continuous
  deployment, and continuous monitoring are the five phases of
  DevOps.
