What is DevOps and the effects of DevOps in increasing efficiency?

In a software project, there are two large departments: Development (Dev), and IT operations (Ops). The mission of the Dev department can be taken from its own name: to develop software and services. In contrast, the responsibility of the Ops department is day-to-day maintenance and management of IT infrastructure to ensure the agreed level of the business’ IT services [1]. Simply put, the Ops team is partly responsible for taking the Dev department’s delivery and putting it to use.

In a traditional model, Devs and Ops work differently and independently. In most cases, one team lacks the visibility and insights into the other. Moreover, there is a remarkable difference between these two departments: Dev is all about quickly implementing changes, while Ops focuses on keeping the production environment stable[2]. Developers often have a joke that “It works on my machine but Ops’ doesn’t”. There were countless meetings, workshops, and communication back and forth, to deliver new features or releases. Unless and until the two groups can reconcile these opposing views and share a common way to think and work, nothing will improve [2].

DevOps is intended to be a cross-functional mode of working in modern software development, where Dev and Ops start to share their roles, concerns, and processes.

It is often difficult to tell if the application is operational when the Dev and Ops team have different processes and opinions. When Dev teams submit a request, the cycle times are unnecessarily extended due to the required communication to align the teams. However, with joint development and operations efforts, the team’s applications are quicker to be in use. This is important because companies’ success is based on their ability to innovate faster than their competitors [3].

DevOps also helps to reduce the costs and risks of the service after deployment. Since there is no handover, the same team that has developed the functionality is involved in the go-live and supports during the riskiest moments. [4]. DevOps also encourages organizational automation, which results in faster and more reliable delivery of functionality after every release.

Going forward, DevOps is a new process that will build a solid foundation for any business thanks to its positive impacts on working efficiency and reliability.

Adopting DevOps model

As mentioned in our previous blog “What is DevOps and the effects of DevOps in increasing efficiency?”, transitioning into DevOps is a cost-effective move. However, that requires a change in culture and mindset. Two traditionally silo teams, Dev and Ops, need to work together to remove the barriers. Only by taking full ownership of their […]

Tests to a software development team are like legs to a whole body that bear the weight of technical complexities in the pursuit of good-quality products. Without tests, the fast cycle of iterations and the market’s requirement of quick releases often seen in modern software development will easily overwhelm the business itself.  Disclaimer: The brands, […]
