DevOps can be termed as brothers in conflict or two faces of the same coin. It is the latest trend in software development, where developers work in tandem with operations staff to ensure that software runs efficiently without any glitches. Today, many software development teams are going the DevOps way, which is not only helping organizations cope with the pressure to produce quality code, but also helping them deliver faster.
According to Wikipedia, DevOps is a portmanteau of ‘development’ and ‘operations’ is a concept dealing with other things like software development, operations, and services. It emphasizes communication, collaboration, and integration between software developers and information technology (IT) operations personnel. This 2019 Technical Skill Report explains the rise in demand for DevOps Certification.
Let us look at how Dev and Ops function:
In delivering valuable software to customers, very often development and operations are in conflict with each other. While development wants to deliver its changes (for example, new features) to customers quickly, operations want stability, which means not changing the production systems too often.
The gap between development and operations occurs on different levels:
As a result, development and operations often act like silos, as they are two distinct teams.
The conflict between development and operations is as follows:
DevOps links software development to operations. It also bridges the gap between agile software development and operations experiences. All experts have at least a basic understanding of others business subjects.
Devops is not a methodology or framework, but is a set of principles to break down silos. Specifically, Devops is all about culture, automation, measurement and sharing (CAMS):
In culture, people and process come first. If you don’t have culture, all automation attempts will be fruitless. Relationship is important in culture. Its functions include:
Other attributes of culture are:
Once you understand your culture, you can start with automation. Now, you can finalize various tools to achieve automation for Devops. Tools for release management, provisioning, configuration management, systems integration, monitoring and control, and orchestration become important pieces for Devops.
What can be automated?
If you can’t measure, you can’t improve. A successful DevOps implementation will measure everything it can as often as it can:
Sharing is the loopback in the CAMS cycle. Creating a culture where people share ideas and problems is critical. Exposing ideas can create a great open feedback that in the end helps to:
Utilizing a DevOps lifecycle, products can be continuously deployed in a feedback loop through:
Devops has proved to be an effective practice and helps in increasing a company’s growth:
