DevOps refers to the combination of the development and operations of the word. It alludes to the joint venture within an organizations’ IT department and operations division. In contrast to traditional software development lifecycles, DevOps is a fine-tuned approach for modern product developers. In layman’s terms, DevOps is no more than a philosophy to iterate, experiment, and proceed with the best-fit alternative for creating digital products. It facilitates and promotes seamless communication between developers and system administrators to get business requirements on track and running.
It remains to be said that DevOps is not a technology, but rather a technological environment. DevOps teams use the following set of technologies most often:
- Cloud Computing, microservices, containers
- Incident management systems, configuration management
- CI/CD i.e. continuous integration and continuous delivery
DevOps is not a take it or leave philosophy but a work-for-all ideology that integrates well with similar paradigms such as Agile development, Lean and Six Sigma, and other project management frameworks.
How does DevOps work?
DevOps runs like an infinite loop that involves cyclical steps like the following to render successful projects:
- Plan
- Code
- Build
- Test
- Release
- Deploy
- Operate
- Monitor
The goal of a DevOps culture is to enable IT departments to create software that meets user expectations. It should be deployment-ready, and perform to meet the benchmarks set by the clientele.
In order to build the desired software specifications project heads exchange ideas and make teams run standalone design sprints. Continuous integration and continuous deployment (CI/CD) is used to provide rapid feedback and integrate changes on the go.
Nobody wants just a workable code. Clients pay for top-quality work that sustains. DevOps practitioners use containers to test and see code viability so it is ready to use upon release and without errors. The changes are implemented individually so that unexpected errors could be well-traced. A continuous stream of feedback is key to achieving optimum results.
What Problems does DevOps Solve?
Software development isn’t as simple as it is often made out to be. IT teams are often constricted and narrow-minded when it comes to adopting new development paradigms. This limits the capability of the software in performance. One of the first, and foremost things, that DevOps does is to do away with lethargic review processes, introduce flexible, all-inclusive feedback loops.
Since the whole project is divided into smaller units of parallel-actionable, a technical bottleneck at one end doesn’t disrupt operations through the project chain.
It passes where traditional SDLC fails miserably. For instance, IT teams will create code which only satisfies the coders and pass it onto the operations team. If anything goes wrong in this stage or at the time of the product release, it is upto the operations to sort it all out.
DevOps simplifies incident management. When software developers choose to follow DevOps principles, they provide a competitive edge to businesses in terms of faster product release times and market capitalization.
What are the benefits of DevOps?
The following benefits can be achieved by departments who switch to the proven DevOps framework:
- Communication bridges between IT groups and operation teams
- Quick turn-around times to market
- Faster feedback integration
- Better product performance
- More automation
- Developers own up responsibility for their work.
- New job roles are introduced which leads to further innovation
What are the Skills Required to be a DevOps Engineer?
As mentioned before, DevOps is more of an ideology than a job description. The profile of a DevOps Engineer means different responsibilities in different organizations. It has been seen that professionals from different domains have taken a liking to DevOps as a philosophy. Yet, a combination of CI/CD knowledge is often expected out of DevOps practitioners. A considerable emotional IQ is also appreciated. The following profiles have also been observed to be on offer in organizations that subscribe to the DevOps ideology:
- Full-stack developer
- Site reliability engineer
- Infrastructure developer
- Build/release engineer
- CI/CD platform engineer
If you have a degree in computer science, then that would be beneficial in acclimatizing to DevOps jobs.
