DevOps

What is DevOps?

DevOps is more than just the latest trend in software development. It is connecting the different types of technologies and methods that have been established within the past years which has put a light on their advantages. The agile model of SCRUM has put developers and testers in small teams so it would only be logical and necessary to encourage the collaboration of the IT-establishment. 

 DevOps stands for Development and Operations, however, it also includes quality assurance. With Continuous Integration and Continuous Delivery established it is now time to turn quality assurance into a logical and continuous process for software testing – Continuous Testing.

 We will help you keep a clear view.


Why DevOps?

The reasons to choose DevOps are obvious: higher, faster, further. Software should reach the market as quickly as possible and thus the release cycles must be as short as possible so we can react quickly to the demands of the market. We also want to be able to grow with the market and be able to react to fluctuating numbers.

Throughout all of this, the quality of the software must be assured. DevOps has a high amount of automatisation that promotes and demands automated testing. There is simply no time for lengthy test preparation, tedious creation of test data or manual testing. Many of the current technologies and methods could help with that and therefore show their full strength in DevOps.

However, rethinking within teams and on a management level are recquired. Departments often seem to work against each other in classic development projects; they are handed over from one department to the other which might make everyone feel like they are contributing to the project, nonetheless, once the project has been handed over, the department loses a sense of responsibility. DevOps starts right there and connects all departments so that everyone can feel responsible for the product.


Together instead of against each other

An essential and probably often underestimated strength of DevOps is the feeling of community. They work together to reach the goal of creating good software; and that across all departments with creation, quality assurance and IT operation. DevSecOps also includes IT security. With cross functional metrics and KPIs, teams will be able to follow the status and quality of the software. Those who have been in such DevOps environments and have seen those dashboards hanging in the company kitchen know the effect: If not all lights are green, coffee breaks are a lot shorter. The motivation to give your best so that the project will be in the green area unites every single one.

Many technologies such as Kubernetes, Container and Microservices support this new type of team work: It makes it possible to divide parts of the product with micro services into logical and easily done tasks, the developer already made work for deployment using containers and finally through orchestrating with Kubernetes they can be scaled at will. When merged into a CI/CD pipeline, every included component including software tests can be completely automated. These technologies make up DevOps and turn it into an ideal overall image.
