Parul University recently conducted a tech session. The session discussed the technical things required for building software. DevOps is a collaborative culture that unites development and operations through an automated toolset. It only works when the culture is right. The write-up below encapsulates how DevOps actually functions day-to-day.
DevOps Is a Culture First
Culture comes before tools.
– Ravi Soni, Enterprise Solution Architect and AWS Community Builder
In the older way of building software, development, quality assurance, IT operations, and management worked in separate silos. When something failed in production, the result was often finger-pointing between teams rather than a shared effort to fix it. DevOps grew up as a direct response to that problem: teams began working together, with developers understanding operations and operations teams understanding development and cloud environments. Automation and tooling can support that collaboration, but they cannot fix a broken culture. Good delivery depends first on habits, communication, and teamwork.
Lifecycle of DevOps
DevOps has a continuous loop rather than a linear process for delivery. The stages of delivery are given below:
1. Plan: planning starts with managing requirements, issues, and the backlog.
2. Code: in this part, software code is written and tracked in version control systems such as Git and GitHub.
3. Build: the code is then used to build software and related artefacts.
4. Test: checking and verifying how the software works and behaves; does it match the expectations or not?
5. Deploy: releasing it into its target environment.
6. Monitor: watching how the live system actually performs.
7. Feedback: feeding what monitoring reveals back into planning, keeping the cycle continuous.
Automation, Done Right
Automation is central to DevOps; it cuts repetitive manual work and lets teams deliver more consistently and frequently. But the speakers were clear about a common mistake: do not bolt automation onto a process you do not understand. Organisations should first identify their real problems and improve their processes, then automate them. Automation amplifies a good process, and it amplifies a bad one just as effectively.
Measuring DevOps: The Four Key Metrics
Building a pipeline is not enough; you have to know whether it is actually improving delivery. Measurement surfaces bottlenecks, slow stages, risky deployments, and recurring failure patterns. The industry standard is a set of four metrics:
- Deployment Frequency: how often you successfully ship software.
- Lead Time for Changes: how quickly a change moves from code to release.
- Change Failure Rate: how often a change causes a failure.
- Time to Restore Service: how quickly you recover after something breaks.
Crucially, the goal is not to deploy more often for its own sake. Speed has to be balanced against reliability; the real objective is faster delivery without losing control of risk. Time to Restore ties directly to service-level agreements (SLAs), since long downtime affects customers, which is why disaster-recovery planning is part of good system design.

FAQS
What is DevOps?
DevOps is a culture where development and operations teams work together and not in isolation; they are supported by automation. Through this, the work is delivered faster and more reliably. Through this, the old methods can be replaced, where teams worked in isolation with shared responsibility. It is throughout the process, from planning and coding to deployment to monitoring.
How is DevOps culture different from tools?
DevOps culture is different from tools because tools can't fix broken collaboration. DevOps has evolved to solve the issues of isolated teams blaming each other for failures. Once the problems are shared, communicated, and the responsibility is shared, automation and tooling make them faster, but without that culture, the same tools work to automate a dysfunctional process.
What are the metrics?
There are four metrics (DORA): deployment frequency (how often you ship), time for changes (how fast a change reaches release), change failure rate ( how often changes cause failures), and, last but not least, time to restore service (how quickly you can recover from an incident). Together, these things make a balance of speed of delivery against reliability.
