Formal and Simplified Definition
A proper and formal definition of “DevOps” has not been coined yet. However, it has been popular by “a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality.” [Len Bass, Ingo Weber, Liming Zhu- computer scientists’ academic perspective] Further simplifying its concept in the IT sector, it is certain practices when employed in software production shortens the system development life cycle and guarantees continuous delivery enhancing quality.
DevOps teams try to automate everything. They have certain roles such as testing new codes to determining how infrastructure is provisioned. The primary task of DevOps is to boost the speed of deployment and improve the time to deploy new codes. Consequently, they write a small piece of software to save time, contrary to larger chunks of codes written by developers which are resource consuming. As a result, the frequency to monitor, measure and improve the operation increases.
Instead of developing software for a specific task, DevOps prepare a configuration management code that describes how certain things should be built. Thus, the deployment of product scales to a maximum. Technically, we can build softwares in several servers operating in a different environment at a time.
The process of development and delivery includes coding, building, testing, packaging, releasing, configuring, and monitoring sequentially. To meet the demand for fast-paced work, certain toolchains come into action, too. An example is the Jenkins Automation Tool (for continuous integration purposes to build and test software projects continuously).
Furthermore, we also use GitHub to control versions (i.e. to track all changes to code); Chef, Puppet, Ansible, and Salt Stack are all configuration management tools to deploy, configure, and manage servers. Besides, the New Relic tool allows us to easily access, visualize, and troubleshoot the entire software stack in one unified experience. This plays an important role after the deployment of software across multiple servers around the globe.
What are the Benefits of DevOps?
DevOps oriented team result in an effective way to meet the needs of the customer in an efficient time. For example, such teams have more time to focus on market needs as the production time has been minimized significantly. Consequently, we spend more times on activities that add more value to their organizations.
Another benefit is it boosts innovations. No doubt, it results in better collaboration between developers and operations which improves the quality and quantity of software deployments. DevOps also result in fewer failures of new releases. In case of any faults, it comes with advantages such as shortened time to fix bugs and also faster mean time to recovery.
In a nutshell, DevOps plays a significant role to meet the market demand more efficiently, deploying performance-oriented and quality software faster. Therefore, having proper knowledge of skills, new tools, and techniques to play the role of a DevOps will no doubt be prosperous to an organization.
