Why You Need DevOps-Doubts You Should Clarify

DevOps short version of “Development” and “Operations” helps software engineers to learn, practice and unifying software development (Dev) and the software operation (Ops).

This software engineering culture strongly recommends the Automation and monitoring the whole process of software construction, from integration, testing, releasing to deployment and infrastructure management. Still confuse ‘Why You Need DevOps’? Ok, read the full explanation in this article for clear your doubts.

The main aim of implementing this software engineering culture is to make development cycles shorter, increased deployment frequency, and more dependable releases mainly. The Core activities listed below

• Processes
• Requirements
• Design Engineering
• Construction
• Testing
• Debugging
• Deployment
• Maintenance

DevOps enable faster delivery to the markets, enhanced customer satisfaction and improved capacity to innovate within the teams. Agile environment enables enterprises to build quality into every individual increment of the application delivered wherein with this mechanism the whole execution process can be streamlined with reliable, fast and quality products to the market.

Principles of DevOps

In one of the technical forum's the following principles published by IBM and the list is still evolving based on the learning’s and practices set up at the enterprise level.

• Develop and test against production like environments
• Deploy with repeatable, reliable processes
• Monitor and validate operational quality
• Amplify feedback loops

The main purpose is to let development and quality assurance (QA) teams to develop and trial against to the systems that behave like the production system, so that they can see how the application behaves and performs well before it's ready for deployment.

5 Important Aspects to consider

• Accept a culture shift: Traditionally the development and operations team had entirely different deliverables and responsibilities. It necessitates the need for a cultural shift among the stakeholders to work for a common goal and encourages Dev and Ops to function as a single team focused on delivering value across the IT value chain. Thus, enterprises should mark a cultural shift in their style of functioning.

• Quality Analyst Role: In this process, both the developers and the testers play an equally important role and typically the QA ties together Dev and Ops teams. It further enables teams to collaborate to have the software and applications up and running. Both the developer and the tester work in close coordination in this environment. But it has been observed that organizations without a strong and definite QA and testing strategy in DevOps faces troubles in meeting their goals for an accelerated speed of delivery.

• PPTs: Three Accelerators for DevOps Process i.e. People, Process and Tools: In addition to the culture change the three accelerators includes people, a proper process to be in place and there is a need for automated tools that may consist of the open source or licensed tools.

• DevOps Cycle: Under a mature DevOps cycle, the process seen is a build, release and operates phases. However, for a typical IT organization, the scope of DevOps cycle spans four functional areas such as:

o a. Continuous integration and testing
o Continuous delivery and deployment, c. Continuous operations, and d. Continuous assessments.

• Importance of Patterns: There are basically four areas with respect to DevOps patterns such as Extend development into production, Create production feedback into development, Embed development into IT operations and lastly Embed IT operations into development. All these patterns are useful as they ensure production readiness of the code and environment. Further, helps to create re-usable user stories for the IT operations and even defines the non-functional requirements that can be used across the process.
