What is DevOps?

Patrick Debois invented the word “DevOps” in 2009. DevOps is the combination of the words “development” and “operations”. DevOps is neither a process nor a technology but a set of practices that merges software development and informative technology operations to improve collaboration and efficiency in carrying out high-quality software products. 

DevOps aims to rationalize processes, improve efficiency, and improve communication between development and operations teams.  DevOps inspirits a culture of collaboration, automation, and continuous improvement by breaking down the traditional silos between the development and operations departments.

What are The Benefits of DevOps

DevOps offers a wide range of benefits to organizations of all sizes and industries. These benefits encompass both technical and cultural aspects of software development and IT operations. Here are some key advantages of adopting DevOps practices:

  • Collaboration: DevOps promotes communication and collaboration between operations, development, and cross-functional teams, by stimulating a shared understanding of goals and requirements.
  • Agile Methodologies: The agile method breaks down the work into smaller stages known as iterations. When the project is broken, small developments, frequent feedback, and continuous improvement happen which make the end product meet the customer's needs. When DevOps is embraced with agile methodologies, improved collaboration, faster delivery, and enhanced user satisfaction are met.
  • Continuous Integration (CI): The changed codes are merged into a shared repository by the developers, where Continuous integration tools such as Jenkins build and test the code to identify any issues early on.
  • Continuous Delivery(CD):  When the code passes the Continuous Integration stage, it is automatically deployed to a staging environment. Continuous Delivery tools such as CircleCI, and TravisCI automate the deployment process, making sure that the application is always in a deployable state.
  • Infrastructure as Code (IaC):  It is the practice of managing servers, and networks using code and automation tools. Infrastructure as code makes the deployment and management processes repeatable, scalable, and version-controlled, in turn making the infrastructure resources used efficiently, reducing manual errors and faster deployments
  • Configuration Management: Ansible, Puppet, and Chef are some tools that computerize the setup of servers and databases, which reduces manual errors and ensures consistency.
  • Continuous Deployment: The code is automatically dispatched to the production environment after it has passed all the tests.
  • Monitoring and Logging:  The applications’ performance is continuously monitored and logged to identify issues and troubleshoot earlier if an error occurs. Prometheus, ELK stack are some common tools used.
  • Automation: it eliminates manual tasks, reduces human errors, and improves efficiency. Automation tools are used for building, testing, deploying, etc.
  • Continuous Improvement: as DevOps uses agile methods, continuous improvement is necessary. Feedback from users and feedback from monitoring is used for improvement and implementation changes.
