DevOps - Understanding Learning

DevOps - Learn about learning

Software development is initially composed of two teams:
The development plan is designed from scratch by the development team and the overall system is constructed.The system requires constant iterative updates.
·The operation and maintenance team will test the code of the development team and deploy it online.Hope the system runs stably and safely.
It seems that two teams with different goals need to work together to complete the development of a software.
After the development team specifies the plan and completes the coding, it needs to be provided to the operation and maintenance team.The operation and maintenance team reports the bugs that need to be fixed and some tasks that need to be reworked to the development team.
At this time, the development team needs to often wait for the feedback from the operation and maintenance team.This undoubtedly prolongs the event and delays the entire software development cycle.
There will be a way for the development team to move on to the next project while the development team waits.Wait for the ops team to provide feedback on the previous code.But this means that a complete project requires a longer cycle to develop the final code.
Based on the current situation of the Internet, agile development is preferred, which leads to faster iteration of the project. However, due to the communication problem between the development team and the operation and maintenance team, the time cost for the new version to go online is very high.This again defeats the original purpose of agile development.
So what if the development team and the operation and maintenance team are integrated into one team and work together to deal with a set of software? This is called DevOps.DevOps, literally an abbreviation of Development & Operations, is development & operations.
