All You Need To Know About DevOps


As a term, DevOps is derived by combining two different terms- Dev and Ops. “Dev” is a vast term that covers all kinds of software developers and “Ops” includes system engineers, system administrators, operations staff, release engineers, network engineers, system security professionals, and various other sub-disciplines.

DevOps is a practice rather than a set of tools. It can be defined as a setup where the development and operations engineers work together through all the stages of a service lifecycle including design, development, production support, deployment, testing, and continuous improvement.

DevOps is essentially based upon a CAMS structure:

  • Culture: This practice requires the organization to build a culture where people and processes are top priorities. It focuses on the overall service that is delivered to the customer instead of the ‘working software’ only.
  • Automation: In order to implement the DevOps practice to its complete capabilities, it is essential to build an automated fabric of tools. Common tools that should be a part of this fabric are the tools for release management, provisioning, configuration management, systems integration, monitoring, control, and orchestration.
  • Measurement: Successful implementation of DevOps requires a team to regularly measure some metrics such as performance metrics, product metrics, and people metrics. Regularly measuring these metrics helps the team to make improvements, where required.
  • Sharing: Sharing of ideas is an important part of DevOps implementation. It involves a thorough discussion of problems between the development and operations teams to find common solutions.

Challenges Solved By DevOps:

In the absence of DevOps application development, a general development scenario includes:

  • A development team that is responsible for gathering business requirements for software and writing code.
  • A QA team that is responsible for testing the software in an isolated development environment and releasing the code for deployment by the operations team, if requirements are met.
  • A deployment team that is further fragmented into independent groups such as networking and database teams.

Since the teams functioned independently, new challenges are added whenever software is pushed from one phase to another. Some of the challenges arising from this setup are:

  • The development team is unaware of the problems faced by the QA and Operations teams which may prevent the software from functioning as required.
  • QA and operations teams have little information about the business purpose and value that formed the basis of software development.
  • Each team has independent goals that may contradict each other leading to reduced efficiency.

DevOps application development helps in integrating the teams and thus, overcoming these challenges. It establishes cross-functional teams that run in collaboration to maintain the environment that runs the software.
