DevOps is a set of practices that combines the processes that are normally carried out by two different teams i.e. software development and IT (operations) teams. The purpose of the DevOps is to build, test and release software faster and more reliably.
- One fundamental practice is to perform very frequent but small updates. This makes each deployment less risky as teams can easily identify the last deployment that caused the error leading to quicker defect resolution.
- Organizations might also use a microservices architecture to make their applications more flexible and enable quicker innovation. This architecture reduces the coordination overhead of updating applications, and when each service is paired with small, agile teams who take ownership of each service, organizations can move more quickly.
- Continuous integration and continuous delivery allow organisations deliver rapidly in a safe and reliable manner.
- Version control – Version control is the practice of managing code in versions, tracking revisions and change history to make code easy to review and recover.
- Communication and collaboration by adopting agile software development approach.
- Infrastructure as code – this is a practice to configure and manage physical and virtual machines programmatically. Engineers can interface with infrastructure using code-based tools and treat infrastructure in a manner similar to how they treat application code. This helps to keep infrastructure resources responsive to frequent changes
- Continuous monitoring – This practice involves monitoring the health and performance of the application and the infrastructure. The purpose of this practice is to mitigate issues proactively and identify any process improvements. This can be achieved by creating and setting up meaningful alerts and collect various data usually through monitoring tools like Nagios.
