Introduction
DevOps is a widely used term in the IT industry, with demand for skilled DevOps engineers rising dramatically over the last two to three years. This growth is estimated to be between 35% and 45%. The job of a DevOps engineer requires a range of abilities, experience and expertise, making it a difficult field. It is no surprise then, that DevOps is becoming an increasingly popular approach within IT and, if a future as a DevOps engineer is something that appeals to you, then you are taking the right steps.
DevOps: what is it?
Patrick Debois, an independent IT consultant, first coined the term “DevOps”. Since then, the discipline has seen significant growth and development. DevOps Engineers, who are formed when developers and operations staff collaborate, can reduce delivery times significantly. With the constraints of Agile in mind, the demand for DevOps Engineers is increasing and causing a bottleneck in the agile software delivery process. Operations teams are struggling to keep up with the speed at which development teams are pushing new changes in each sprint, raising concerns over the stability and security of applications.
DevOps Engineers have been instrumental in bridging the divide between development and operations teams, ensuring collaborative workflows. A range of techniques and technologies are leveraged to facilitate effective communication and collaboration. Further, continuous monitoring can help to optimize infrastructure agility, simplifying application management and security.
When Does the DevOps Model Kick in and What Does Each Phase Entail?
1. Unceasing Growth
As the first step in the DevOps lifecycle, Continuous Development involves the full cycle of creating a software product from the ground up. DevOps Engineers must first envision the final product and then create a plan around it. Once the plan is in place, developers will then write and modify the code, which is commonly managed through source code management systems. Popular tools used for this purpose include Subversion (SVN), Git, Jira and CVS.
2. Ongoing Combination
It is important to ensure a seamless transition from the Continuous Development phase to the Continuous Integration phase. This phase consists of numerous activities, such as understanding the project requirements supplied by the customer and preparing test execution for the testing stage. Source code changes are to be carried out regularly, usually on a weekly basis. Due to the fact that potential problems with the code are most likely to be identified during the Continuous Integration phase, this is why it is commonly referred to as the ‘heart’ of the DevOps lifecycle.
3. Constant Examination
As part of the Continual Testing phase, the code is continuously tested for any flaws or vulnerabilities. It is determined at this stage if the product meets the client’s requirements and the application’s usability is tested using a set of standard QA methods. Automated testing solutions, such as open-source tools such as Selenium or advanced test management systems such as QARA Enterprise and TestNG, enable continuous testing. DevOps Engineers in QA teams can make better use of their time and resources by running multiple tests at the same time using the tools available.
4. Constant Deployment
Continuous Deployment is the fourth stage of the DevOps lifecycle. It involves delivering code in a way that does not affect the features of the product or website. Verifying that the code has been correctly installed on all servers is critical at this stage. Ensuring that the product is deployed accurately and completely without any errors is of the utmost importance.
5. Ongoing Tracking
The fifth stage of the DevOps lifecycle is Monitoring, which involves the collection and analysis of data related to the application in order to identify any issues and overall trends. Once the software has been launched, it can be monitored and adjusted to ensure optimal performance as part of an ongoing operational process.
