What is DevOps?
DevOps as we speak is referred to as a business drive that aims to improve not only communication but collaboration among the development and operation teams. The purpose here is to increase the speed and quality of software development. DevOps can be considered a new and more effective way of working that encloses in it profound implications for organizations and teams.
Importance of DevOps:
In a 2020 DevOps trends survey, it was found out that, 99% of the respondents claimed DevOps to have a positive impact on their organization. DevOps transformation is something that requires an overhaul of business structures and process that are without any doubt well worth the effort.
In another DevOps study that is “DORA’s State of DevOps 2019”, we found that all the elite practitioners managed to release 208 times more frequently and also 106 times faster than all the low performing teams. And this is not just the speed we are talking about, it’s the improved quality that DevOps yields which has led the elite teams to boast a change failure rate seven times lower as compared to the low-performing teams.
Best practices for implementing DevOps:
Below you can find details about some of the best practices for implementing DevOps.
Agile project management:
We all know agile in known to be an iterative approach to project management and software development as well. It helps different teams to deliver value to their customers not only faster but with fewer headaches and more quality. The focus of agile teams is to deliver work in smaller increments and work in it more effectively instead of working on the entire product and then wait for a single massive release.

Building with the most relevant tools:
In the DevOps lifecycle it is very important to use the right tools. It is important because in each phase we have to improve software quality and speed of delivery and using the most relevant tools serve the purpose. If the DevOps toolchain doesn’t use the right tools for each phase, not only the quality of the product or value delivered would be poor but it will also put a bad influence on the customer.
Shift left with CI/CD:
When we say the teams have “shift left” this means that they are ringing testing into their code development process before the set time. This means that a variety of tests are performed in the entire coding process instead of just sending multiple changes to a separate test of QA team. This will help developers to fix bugs and improve the quality of code, while working on the relevant section of codebase. And this is how the implementation of continuous integration and continuous delivery (CI/CD) and deployment supports the ability to shift left.
As we have just read above that continuous integration and delivery can help developers to merge the code regularly into the main repository instead of just checking the code manually and CI/CD is something that automates this process. In addition, the CI/CD automated testing is found to be very essential in successful DevOps practices. So it is very important to implement the automation process for merging the code regularly into the main repository.
Monitoring the DevOps pipeline and applications:
There comes a time when a broken build or even a failed test can cause unnecessary details. And that is why it is very important to monitor the DevOps pipeline. The automation without any doubt enhances the speed of development process to a great extent. But what if there is a failure in the automated process that nobody knows of? So that is why you’re better off doing this work manually. Similarly, it is also very important to monitor the production of applications so as to identify any failures or performance deficiencies.
Gathering continuous feedback:
When we are given feedback on a certain task or performance, it gets easy for use to understand where we lag or what have we done so far. Same is the case here where continuous feedback is very important why because it is something that guarantees for the team members to have all the important and relevant information they need to do a more meticulous job. If we talk about the continuous feedback from the development perspective then this ensure the team is alerted enough to any pipeline failures instantly. Similarly, it also shows that clear and thorough code test results are shown to the developers as early and quickly as possible.

Changing the culture:
The first rule of DevOps is collaboration, trust, transparency, and empathy. If you are lucky enough to have your organization being the one to possess all these qualities that it would be very easy for your teams to adopt DevOps practices. But if for any reason your organization doesn’t possess such skills then these barriers must be removed by implementing a proper strategy. Here the most common organizational structure is to give different teams separate areas and responsibilities and minimize cross-team collaboration or communication as well.
We know it is very important for organizations to hone DevOps practices in their teams and that is why they must focus on people and processes and start their DevOps transformation. We hope these above-mentioned DevOps best practices would be of some use to different organizations in understanding how important these practices are.
