DevOps (a short-term given to development and operations), like most new approaches, is just a buzzword for many people. Though everyone talks about it, not everyone knows what it is.
What is DevOps?
To be precise, DevOps is a methodology. The idea of this methodology is to create a new mindset – a mindset where the developers and operations team combine their efforts to achieve the common goal. Sometimes it is mistakenly confused with a tool or a role. It’s not a tool, although it uses a toolchain to automate software delivery and deployment.
Today business demands faster and continuous delivery. Due to the various challenges and contradicting goals and objectives of the development and operations teams involved in the software delivery, it seems difficult to achieve this task.
The job of the Development team is to build software and apply changes to incorporate new features, fix bugs and fulfill the internal as well as the external requirements. On the other hand, the Operations team focuses on stability, reliability, and performance of the systems to minimize the chance of software conflicts and incidents. The two contradicting goals of the two teams create a wall of confusion. The main problem that arises is the lack of cooperation and communication. As a result, the software is not delivered at the desired pace.
So what make DevOps the ultimate solution to cater to such problems?
- Infrastructure as code (IaC) is an approach where servers can be configured automatically as code that can be managed with the same tools and processes that software developers use, such as version control, continuous integration, code review and automated testing. This approach lets you make infrastructure changes more easily, rapidly, safely and reliably. Puppet is a tool largely used for IaC.
- Microservice Architecture is an approach in software development where the application is divided into loosely coupled parts. Imagine you have a modern social media messaging app with chats, stories, voice calls, bots, and so on. All these can be developed like independent mini-applications. This approach makes it easier to maintain, test, and reuse parts of the application.
- Automation is the key to DevOps culture. Automation helps standardized production environment to make deployment predictable. This makes people free from the routine task, allowing them to concentrate on more creative aspects of their role which leads to enhanced performance.
- DevOps tools consist of configuration management, test and build systems, application deployment, version control and monitoring tools. DevOps supports tools like Jenkins, Ansible, Docker and Puppet. Still, the tools only facilitate the process and allow to achieve the goal. Knowing how to create Docker container doesn’t necessarily mean that you are in a DevOps club.
DevOps is an approach that combines Developers and Operations team to develop and deliver software more efficiently than a traditional siloed approach. The Operations team can share valuable information from its experience in managing production environment. This information can help the Development team to design and develop robust applications. A critical part of the transition between the Development and Operations teams is knowledge articles. This transition can only be achieved when the wall of confusion is broken down.
