What is DevOps?
DevOps is a combination of Development and Operations. It’s one of the latest trends in software development, and with it, the developers and operation staff can work together to ensure that the software runs efficiently and there are no errors. Software development teams are now using DevOps. It helps them to cope up with the market pressure. And they can deliver the software in less time. Thus, they are earning more profit. And if you want to learn DevOps, you can contact Naresh I Technologies. We provide complete DevOps training for all DevOps certifications. Naresh I Technologies also is the number one computer training institute in Hyderabad and among the top five computer training institutes in India.
You can consider it as the development and the operations working together and is a concept which deals with various things like software development, services, and the Operation. Three essential things are collaboration, communication, and integration between the IT operations personnel and the software developers. The recent past has certified the importance of the DevOps certification.
How Dev and Ops Function:
- The requirements of the developers are continuous change, and they always want to add new features.
- The Ops, on the other hand, want to ensure stability all the time, and they always look to come up with new services.
The Problem
Have you seen head and tail fighting? It’s a fight that is always won by anyone. However, have you seen Head and Tail together? DevOps is something like that. It’s head and tail on the same side of the coin. The development team always wants to update the production environment with the changes it commits, and the operations team wants stability and the least changes. However, the dilemma is both of these are important.
And on many occasions, the development and operations come in conflict with each other while delivering value. The operations tea wants to ensure that the production system does not change so often though the development team keeps asking for the change. And hence there is a gap in between the development and the operations which occurs at various levels.
Incentives gap: development and the operations team have different goals.
The Process gap: There is a different approach between the development and the operations for managing the changes. That needs to be in the productions, and there is a need to maintain it as well.
The Tool gap: The development and the operations make use of their tools for doing their work. And hence there is a gap in between the tools used by the two sides.
The result of this is that the development and the operations work like silos, and both are different teams.
The conflict between the development and the operations
The main reason for the conflict between the development and the operations is that the development team wants continuous change, and the operations team always fear making the changes.
Is DevOps the Solution?
The DevOps binds the “software development” and the “operationteam.” It reduces the gap between agile software development and operations. And all DevOps experts do possess the knowledge of all business matters.
Why DevOps?
The DevOps happens to be a culture and not just a methodology or the framework. You can consider it a set of principles for breaking down the silos. You can use it if you think of collaboration, measurement, automation, and establishing a culture.
Culture
When we talk about culture, we talk about the people and the process. If you don’t possess a culture, the automation will never work. There should be a relationship, and only then automation is possible. And DevOps make that possible. You can kill the silos, engage often and early. You will have options and never get a chance to blame any team member as all leverages the correct picture of the “software development” and “IT operations” work all the time. You can communicate with peers, ask questions, scale to any level, do almost anything, and ensure the best security.
Automation
There are various automation tools for DevOps, though you need to establish the culture. We have tools for provisioning, configuration management, release management, monitor and control, and orchestration.
Why Automation?
If you have the same thing to do, again and again, you need automation.
Automation is efficient as well as saves a lot of time.
It saves a lot of “manpower,” and hence the money as well.
What can be automated?
You can automate the builds, testing, deployment, early fault detection and rectification, system upgrades, and system configuration.
Measurement (Metrics)
- Measurement is a necessity for improvement. And a successful DevOps implementation helps you to measure all it can and also regularly.
- The performance, process, and all metrics can be the basis of measurement via the DevOps.
- You thus improve over-time via capacity planning, fault detection, and trend analysis.
Sharing
Sharing can solve the problem, and with a good team, you can solve any problem, but you need to share. And you can share your ideas, metrics, technology-related details, code, instructions, test cases, and almost anything.
Evolution of DevOps
“Patrick Debois,” a Software Development Consultant, researched all aspects of IT. He worked as a developer, network specialist, system administrator, tester, and project manager. Amid, Patrick got a consulting job. And there, he has to deal with the data center migration. He looked after the testing job, which meant he spent a lot of time in “Development” and “Operations.” However, the conflict between the development and the operations bothered him. And he got frustrated while facing the challenges of work management amid this data center migration.
Continuous integration got recognition from the agile community. And, it became quite close to the development. However, still, the conflict between development and operations was there. Though Patrick believed that there is a way to make these two teams work together. And it was his effort plus some others like Andrew Shafer and John Allspaw and a few more that made the DevOps a reality. Agile development methodologies play an important role in DevOps. We recommend you to have a read about the complete evolutionary history of DevOps.
DevOps Lifecycle
The DevOps Lifecycle is on Agile methodologies. It comprises continuous development, builds, test, deployment, and update stages, and the process repeats with an update. The update is a change from the developer. Or It can be a request from the test team for correcting the code. Or it can be like an infrastructure upgrade and much more. However, all you can summarize with code, build, test, deploy, and update stages.
Technical benefits
There are various technical benefits like continuous delivery, less complexity, early fault detection, rectification, and zero downtime.
Business benefits
There are various business benefits like faster delivery, better stability, and time-saving ensuring more profit.
