DevOps is one of the biggest buzzwords in the world of technology in recent times as It offers a massive amount of benefits to the organization to shorten their software development life cycle.
What is DevOps?
There is no single definition or right answer to the question, “What is DevOps”?
DevOps is not a tool, technology, or framework; it is more a philosophy and a concept. It is a set of practices that combines software development (Dev) and IT operations (Ops), which helps to shorten the systems development life cycle and provide continuous integration and delivery with high software quality.
- Improved collaboration and communication
- Faster software or product delivery
- Continuous cost reduction
- Improved process
- Faster resolution of issues
