Everyone talks about it, and it’s the only buzzword for many people. DevOps short for Development and Operation is a process framework or a set of methodologies. IT unites both the team of developers and IT operations under an umbrella. It is an approach based on lean and agile where the client, development team, operation team, and the quality and assurance team collaborate in developing software with constant communication for improvement using tickets to quickly deliver the software on time. DevOps came into being recently in 2009, and since then, this business-driven software is gaining popularity among the IT masses. Earlier the software was quite large and mostly functioned as a system record. With the accent of mobile communication and the maturation of web applications. System records were obsolete and were used only for the system of engagement where customers directly reached the businesses.
Later with innovations like cloud computing, big data, social media, and mobile applications, the traditional approach crumbled, hence the intense focus was divided to enhance speed in delivery, increasing customer satisfaction, and engagement which are principles of DevOps.
Identification of bottlenecks in the delivery pipeline
- Unnecessary overhead in the form of communicating repeated Information.
- Unnecessary rework and revising plan every time due to defects found in the testing phase lingered the slightest things and caused delayed response and delay in delivery.
- The overproduction of functionality development made the process more complex.
- The biggest bottleneck is the deployment of infrastructure.
These bottlenecks were easily overcome by DevOps through a software-defined environment that enabled practitioners to capture infrastructure as a programmable & repeatable pattern that accelerated deployment. The pipeline moved with an even flow from the end-to-end end with equating throughput to avoid backlogs.
The culture
DevOps is more a cultural movement at its bedrock. It united teams to carry out a single business mission forgoing the departmental objectives. DevOps could actually make cross-culture collaboration possible, and that’s the reason for its success.
Change management
DevOps is a business process that brought change management process from theories to reality in Application Life cycle Management automating the change management processes. So, it enables the enterprise to link work items to all artifacts, project assets, and other items. They create modified and destroyed by professionals in the process.
Package Repository
DevOps used package repositories like GitHub master version to serve professionals to store and save binary codes designed during the genesis phase of SDLC. It helped in the deployment of infrastructure and stored configuration files, infrastructure as code files, and deployment scripts for future reference and change if any, and also made accountability visible throughout the SDLC.
Usage of Cloud
One of the tenants of DevOps is to develop and test on a production-like environment on the cloud, which enabled the practitioners to have on-demand availability of environment and access. It leveraged the pattern technology and gave the creators an edge over the traditional approach. It also facilitated dynamic provision and de-provision that reduced the cost and time factor. From an automation and virtualization perspective, it enabled simulation in conjunction with the cloud environment.
These are some of the path-breaking features of DevOps that make it worthwhile. And a certified DevOps practitioner is always desired by the Sprintzeal organization. So, the HR manager looks at such factors in any employee who can jam in and bring in new skills with him.
