DevOps is where traditionally siloed organizational units work together to increase the business’ ability to rapidly deliver applications and services. This increase in speed enables businesses to be more competitive and to respond to customer demand in a more timely manner.
The DevOps model is where the development and operations teams in the IT organization work together rather than independently. The “engineers” (developers and operations staff) are involved in the complete lifecycle from development through testing to operations.
These teams have to use automation to ensure that old processes are done faster and ensure that there is no information loss when crossing “old” organizational boundaries.

The benefits of DevOps

• Speed – move the business faster so that it can adapt more rapidly and satisfy customer demand more quickly.
• Reliability – ensure the quality of updates (to applications and infrastructure) so that customers can trust the improvements implemented.
• Scale – ensures the development and operational services can easily be scaled.
• Build more effective teams – under a DevOps model the development and operational teams work as one where they share their responsibilities and workflows so in effect they are a single team.

DevOps Is Important

When software development started it supported the core processes of the business – for example, one of the first areas for computerization was accounting. Now, software no longer supports the business functions it has become integrated into the business to such a degree that without it the business fails. Businesses interact with their customers, partners, suppliers, etc. through software. This is as well as making the business itself operate more effectively.
DevOps is essential to make businesses support all these application requirements quickly and effectively.

DevOps Essentials

It is essential that automation is used for DevOps to be effective and there are lots of tools on the market that assist with automating the processes.
However, the one area that most DevOps tools vendors miss is the boring topic of documentation. When studying the DevOps process communication is one of the most critical components but is also the one that is disliked the most and therefore often gets ignored.
One of the tools that must be used allows the business to automatically document the software that is being developed (new code and enhancements to existing code) and produce a repository of that documentation that is consistent across the board. This can then be used by both the development and the operational engineers. They have different requirements but the same document set is useful to them both, and it is automatically produced in a consistent manner.
