There is an issue with the server build, it experiences high load and is unable to run programs. What if there are problem with the operations carried out development of the server by the development team. Finding a solution for such a problem was difficult earlier when there was no concept of DevOps.
What is DevOps and what is its purpose and principles?
We define DevOps as an approach for collaborating operations and development engineers for the purpose of improving the relationship between the two. It focuses on moving towards a culture that partners operation and development staff together to ensure proper running of software with minimal number of problems and a workflow that is stable and fast.
This concept of DevOps is based on professional principles that help business units merge and break down the traditional silos. Role of Devs is to create changes and modify or add features whereas the role of Ops is to enhance services and create stability, this methodology combines the features and advantages of two into one. You can develop and test in an environment similar to production.
Lets discuss about, Why is DevOps being adopted?
According to a survey in Portland in 2015, DevOps practices, such as continuous delivery and strong team collaboration, have been proved to increase agility as well as reliability: Top IT organizations are deploying code 30 times more frequently with 50 percent fewer failures. Its adaptation is also driven by factors such as increased usage of datacenter automation, demand of increased rate of production and use of development processes such as agile and other methodologies.
What are the problems that occur in DevOps concept?
The two participants work together towards improvement but still there occur gaps between some of the concepts. Now, looking at the gaps that DevOps face: starting with developers, they will have faster turnaround time with respect to features, whereas, ops have lesser turnaround time with respect to feature deployment. Also, Developers are not much concerned about the infrastructural as well as deployment impact but ops are. Devs don’t deploy consistent software and ops are motivated to resist change. Moreover, development process is agile and operation process is static.
In spite of these gaps why do they work together?
They work together to understand the impact of code changes, developers focus on metrics required by ops team. Ops have more clarity on infrastructure needs that result in more automation on deployment along with better communication and collaboration. They work together to compete with delivery challenges they face, like, release management, release/deployment coordination, release/deployment automation, that requires management and tracking of discrete activities. Moreover, automation of monitoring, testings, builds and self healing can be carried out.
Now, if we compare the Agile and DevOps methodologies, Agile development bridges the gap between customer requirements and development teams whereas, DevOps does that between Dev and Ops teams. Both focus on functional and non-functional readiness and DevOps does on business and operational readiness too. DevOps intensifies reusability and automated release management.
