NetDevices explores DevOps.
What is DevOps?
The term DevOps comes from the fusion of the words "Development" and "Operations". It represents a geek-oriented philosophy. It encourages a change in mentality and greater collaboration between development and operations teams.
It's an approach that automates and optimizes processes between software development teams and operational IT teams. As a result, software can be created, tested and deployed faster and more reliably. DevOps breaks down the barriers between development teams and operational IT teams. They work together throughout the software application lifecycle (e.g. development, testing, deployment and operation).
What are the benefits of DevOps?
- Quality and efficiency improved code and better-defined processes
- Improved deployment time optimization of development time and greater anticipation
- Better communication between developers and trades
- Fast, frequent delivery small versions
- Reducing risks and returns backwards
- Cost reduction long-term
How does the DevOps approach work?
DevOps is a method for improving processes throughout the software development lifecycle. The process resembles an "endless loop", starting with software planning. It then passes through the coding, build, test and release phases, before returning to planning via deployment, operation, continuous monitoring and feedback. Ideally, DevOps enables teams of developers to create software that perfectly meets users' needs. This software can be deployed quickly and run optimally from the first time it is used.
The main DevOps methods and principles
Old agile software development methods continue to influence DevOps practices and tools. Many methods, including Scrum and Kanban, incorporate elements of agile programming. The latter is characterized by greater responsiveness to changing needs, the realization of daily stand-ups and the integration of continuous customer feedback. The Agile approach also advocates shorter software development cycles than traditional waterfall development methods.
Scrum defines how team members should work together to accelerate development and quality assurance projects. Practices include important workflows and specific terms (sprints, time slots, daily Scrum meeting) as well as certain roles (Scrum Master, Product Owner).
Kanban was born out of efficiency gains at the Toyota factory. It effectively stipulates that the status of ongoing software projects must be tracked on a Kanban card. The number of parallel jobs, Work in Progress (WiP), is limited. As a result, lead times are shortened and problems, such as bottlenecks, are quickly identified.
