DevOps is not any specific technology. DevOps is a shift of methodologies, an approach to software development which has been discussed in the series of article Basics of DevOps. Traditionally, development team and the operations team were separate. The development team design the system, build, test, and then deliver it to the operations team. The operations team uses it for work and reports errors to the development team. In DevOps, a development team (Dev) collaborates with the operations team (Ops). Various organizations are leaning to shift their systems to digital, hence the demand for DevOps Foundation Certification is growing. The reason for this upward shift in demand for the course is the impact of DevOps on the workforce resulting in reduced development time, frequent product release, continuous deployment, and high product quality.
Pros of DevOps:
DevOps often provides cloud-based services to easily associate the tools. It provides separate operations, which means each developer focuses on a single tool without understanding the entire toolchain. DevOps makes better collaboration and faster turnaround.
