How to Learn DevOps

What is DevOps?
DevOps (a combination of Development and Operations) is a culture, movement or practice that values communication and cooperation between "software developers (Dev)" and "IT operation and maintenance technicians (Ops)." By automating the process of "software delivery" and "architecture change", software can be built, tested, and released more quickly, frequently, and reliably.

• DevOps is the sum of a series of principles and practical experience.
• DevOps put the development and operation and maintenance teams into the same system development from the beginning.
• DevOps provides a fast and effective way to continuously deliver value to users in the form of end-to-end communication, and this method is consistent and feasible.
• DevOps shortens the time to go online and ensures the market competitiveness of the business.

Why DevOps?
With the popularity of the concept of microservices, more and more companies have joined the camp of microservices, but microservices are not a silver bullet. While microservices bring benefits, they also introduce complexity, so a series of standards need to be specified To reduce the complexity of microservices as much as possible, DevOps has also emerged with the popularity of microservices.

DevOps meets the following needs and expectations of users:
• Get the features they want;
• Get the functions they want when you need them;
• Can update functions faster;
• The quality of the new version released is high enough.
