DevOps is one of the trending topics at the moment and is been developing. DevOps is a set of development practices which bring out collaboration, communication, and automation throughout the application lifecycle of DevOps.
DevOps and Agile are said to be perfect couples as they complement each other. While Agile prepares a methodology to manage the project, DevOps will be helping to deliver the output.
DevOps has been changing regularly to the required business needs by changing the software development strategy over the years.
It is essential to learn that Agile is not DevOps, and DevOps is not Agile. If agile practices are not followed, it is difficult to obtain success in DevOps. Agile can make sense independent of DevOps but it can be completed when accompanied by DevOps practices.
DevOps means continuous delivery and Agile means Scrum. In DevOps community, whoever is having Agile experience approve that scrum is a useful source for tracking their planned work.
DevOps is generally the extension of Agile’s principles which include operations and systems instead of ending their involvement at code check-in, and work with an objective to deliver software fully to the customer. Agile teams basically use continuous delivery, test automation, automated build and continuous integration.
Considering DevOps & Agile as the same thing can lead to something undesirable as the teams should abandon good and safe practices.
Difference between DevOps & Agile is as follows:
Deployment vs Finished Project:
Basically, Agile methodology helps the organization to focus on the development of software and explains the steps to be taken to finish the task. In the final step of the project, Agile favors to quit. This method moves onto something else.
With DevOps, you continue forward, deploying the software in a way that is reliable and safe.
Scheduling has a different way of approach with DevOps and Agile. Agile works in a short time called as sprints, which starts work in the immediate future and they rarely last longer than a month. Teams can depict easily when another sprint starts and can adjust their work.
DevOps doesn’t have a determined schedule. Instead, it believes in decreasing disruption of schedule. Instead of speed, DevOps seeks to make the best product possible which is reliable.
Definition of Agile & DevOps:
DevOps sprang from the Agile model which works beyond the software developers. Both the DevOps and Agile strategies aggregate each other for a swift production and quick delivery in different ways avoiding the traditional development process.
Agile divides its complex work into sub-tasks called modules. This takes a longer time than DevOps to complete the product as it mainly focuses on the complex projects. Agile is the imperative part of the success of DevOps.
Agile and DevOps Team Size:
Agile believes in the small teams and faster work delivery with fewer difficulties. DevOps, is a vice-versa, believes in the number which means bigger the better.
Mostly all the teams come together as a single team to work on different theories. It is obvious that Agile methodology involves using the scrum model and cannot contain huge numbers which may lose effectiveness with the addition of the new person in the team.
DevOps is said to be involving the collective work of several teams. Some people can work on kanban, waterfall and scrum model, but all these carryout to come together at the point of release for analysis with the deployment team. By this, we can understand that the DevOps methodology doesn’t depend on any other development model.
Fragmentation Vs Cross-functional:
Understanding the process of teams work is very important. Roles on the team, that focus on Agile method is allowed to do all responsibilities of work which helps to replace one person with another one. This works pretty well while developing software, as it helps in the development and communication of the team.
DevOps consists of two separate teams – Development and Operation teams. Developers and operations engineers are all specialists in their area of work and to be aware and lessen time they have to communicate a lot in order to achieve wanted results.
DevOps strongly depends on the automation of the deployment, which is necessary for this process to be carried out reliably and without problems. The relevant tools are a part of DevOps.
Agile-command, on the contrary, can choose which tools to use, because this technique does not impose any requirements on tools.
As discussed earlier, one among the Agile’s priority is working software over detailed documentation. But this methodology doesn’t need documentation as the team has daily meetings. Without documentation, the project cannot be transferred to another team.
DevOps has a whole different situation. The quality of the product depends on the cooperation and understanding between several working groups. This is why documentation is very important.
DevOps is a popular methodology. It is an ongoing improvement cycle that software development models experience regularly. So you need to understand and communicate it to master CI (continuous integration) and automation tools to increase and add value to your automation efforts and makes it easy enough to quickly adapt to the changes.
Agile is mostly based on Lean Thinking as it encourages in eliminating the non-value added activities in delivering software projects. However, Agile has its defects too, as it helped to the cause of the rise of DevOps, which is the origin of Agile software development.
