In the early days, the Software Requirement Specifications (SRS) were not dynamic like today’s, thereby giving the developers enough space and time to create their product and make updates if necessary. But today as the internet access is wide spreading, there are thousands of people testing products and rating them and not to mention, providing feedbacks. These constant feedbacks are scrutinized by the operations team and used to constantly update the System Requirement Specifications that goes to the Developers’ team. This is what brings the need of DevOps to today’s work ethic.
But the concept of DevOps was not always there explicitly. The model that was used before the DevOps was called the Waterfall Model, which meant gathering SRS, planning and designing the SRS, implementing it, Testing the codes, deployment of the code and maintaining the code at regular intervals all in separate phases. This meant that there were challenges; longer times for code deployment, difficulty in automation and diagnosing issues, difficulty in maintenance, etc.
What is DevOps?
DevOps is a methodology of software development that focuses on communication, integration, automation and cooperation between the developers and the operations team.
Breaking it down
Development of a software or an application is about writing a code, integrating it and running it. Once the code runs fine, it is sent to the operations team that works to check the security of the code, the amount of power a system would require to run the code, how can the code be made more efficient, etc. The work of the two teams cannot be independent. They are both very much interdependent and can only work with each other’s feedbacks, especially now that the entire system has become so dynamic.
What is the need for DevOps?
DevOps ensures faster, more reliable, more stable and more secure work flow. Most IT companies and organizations see a regular inflow of feedbacks from customers and a need to deploy thousands of codes in a day, fading away the streamline of the work flow.
More simply, when thousand of feedbacks are sent to the operations and the development teams for corrections and changes, they are new to them as well. One cannot be prepared for all the problems that might occur with their product, beforehand. Nor can they know in the slightest of chance of ALL the bugs that are in their code. So, every time a problem or a feed back comes in, it is more likely to be new than not.
This effect of turbulence in the teams due to the dynamicity essentializes the incorporation of the DevOps method for working, in every company. Which brings us to the next query most of the readers will have.
Are there companies that have incorporated the DevOps?
Oh, yes. There are a number of big shot companies in the game that have incorporated DevOps. Companies like Netflix, Etsy, Facebook, Twitter, Google; almost every other hero in the game, has been working on the methodology of DevOps. And not to mention, they have seen incredulously smooth functionality and consequently, tons of profits and success.
What is the level of demand of this method and the skill regarding DevOps today?
There is enough demand for DevOps skills today and that has given birth to a number of certification course providers in this field. Many courses are available online and offline and are highly suggested, given the level of demand.
What are the benefits of DevOps Certification?
Few of many benefits of DevOps Certification include:
- Better opportunities for jobs
- Increased productivity
- Better efficiency
- Better salary
- Software stability
Therefore, DevOps is highly beneficial in all regards. One must definitely choose the certification course based on the professor, the university or coaching center providing the specialization, the number of hours, the objective of the course, how project oriented is the course, and the price of course.
Most business today, whether they are well established or just budding start-ups, are looking towards employing DevOps skills and incorporating its methodology. Especially because the concept is fairly new, there is a large gap between the number of DevOps skilled individuals and the demand for them, thereby giving huge opportunities to people who have skills. Thereby making it extremely useful to have the DevOps certification.
