Devops as a service | Information Systems homework help

The very idea of ​​a DevOps service    was formed in the recent past, when the problem of effective cooperation between development and operations teams was ripe: each side immediately blamed the other for various failures. Roughly speaking, when the code ran as it should at the developers’ booth, they confidently sent it to work. And when there were failures, IT teams said that the problem was in the code and developers should deal with them.

Such “kicking off” increased the time for rolling out releases and worsened the quality of the product. And if a lot of changes rolled out in one release, it became difficult to understand what caused the problems in real-life operation. These problems became the prerequisites for the formation of a new approach to working with digital products, which was later called DevOps. It reflected the process of combining two practices – development and operation – into one continuous process.

Like the automotive industry, software development faces the challenges of a sub-optimally tuned build cycle. Bottlenecks can systematically occur in the development pipeline, causing the overall process to become unbalanced. The most vulnerable, in terms of delays, stages are making changes to the code, testing them, and deploying them. To eliminate delays, and in general, to speed up and automate the entire process, various techniques are used; one of the most effective is DevOps (Development Operations).

DevOps is a specific culture, a set of interdisciplinary practices, the main goal of which is to unite everyone involved in software development into one team for continuous code integration and rapid delivery of applications to the user. The DevOps culture relies on the CI/CD (Continuous Integration & Continuous Delivery) methodology and CI/CD-optimized tools: GitLab, Docker, Kubernetes, etc.
