DevOps is a great strategy that allows various companies’ developers to experience better product success. With the buzz surrounding DevOps, it is easy to assume it is a technology solution that solves your production and quality issues. However, DevOps is more of an approach that can change work culture by reinforcing collaboration and cohesiveness.
Previously, the waterfall was the approach that led developers to create robust products. However, it consumed massive amounts of time, and additionally, there was a lot of scope for improvement throughout the methodology. The primary area that needed to be bettered was that developers and operations staff members were siloed differently, and they had a tough time hammering out the differences that sprouted along the way. From bugs to source code modifications, there were a significant number of challenges that impeded the methodology.
Seeing the potential for a new approach, a group of developers got together in 2000 and penned ‘Manifesto for Agile Software Development,’ which paved the way for the agile development process. The software was developed in large batches and deployed as a whole package. The software development was broken down into smaller batches with the agile approach. This enabled the project members to develop and deploy iterative updates, which were relatively more straightforward to modify and sported little time to market.
DevOps brings in many principles from Agile. However, it is not the same as its predecessor as it differs from agile and waterfall. While those differences can always be discussed, let’s not digress. While penning other blogs, our team saw a disturbing observation from Gartner.
According to Gartner, “through 2023, 90% of DevOps initiatives will fail to fully meet expectations due to the limitations of approaches used by leadership, and not technical.”
This brings forth a new and often ignored perspective: DevOps security has its own set of flaws. While its advantages motivate its adoption, companies should also understand that every technology has disadvantages. In this blog, we shall explore a few things related to DevOps methodology, the principles of DevOps, and the pros and cons that come with them.
What is DevOps Methodology?
The DevOps methodology encompasses the fundamental principles and ideas that harmonize the domains of operations and development. The DevOps culture emerged roughly a decade ago and incorporated the DevOps Life Cycle Management, encompassing the stages of Planning, Coding, Building, Testing, Releasing, Deploying, Operating, and Monitoring.
The adoption of the DevOps culture is nearly ubiquitous among software companies worldwide, yielding remarkable advantages. In 2020 and beyond, the demand for DevOps professionals has surged, with certified individuals being particularly sought after over their non-certified counterparts. To delve deeper into this field, consider enrolling in a reputable institute’s DevOps training program and attaining a professional certification.
The conventional Software Development Life Cycle (SDLC) suffers from numerous drawbacks, including high costs, a plethora of errors and bugs, delays and errors caused by human intervention, software realization only at the end of multiple cycles, lack of automation, segregated operations and development, minimal collaboration, inadequate team communication, prolonged timeframes, and an inefficient and ineffective culture. These shortcomings were the catalyst for the emergence of the DevOps methodology.
The DevOps Life Cycle (DLC) offers several advantages that were absent in the traditional SDLC. In the DevOps culture, the Continuous Integration/Continuous Delivery (CI/CD) pipeline constitutes an ongoing process encompassing all the sequential steps in product development.

Principles of DevOps
DevOps and agile are similar to some extent. However, DevOps methodology prioritizes automation and focuses on merging development and operations members as one unit. These benefits are pertinent in this modern-day as demands are rising, and keeping up with the changing demands, automation, and resilience are vital to staying relevant in the changing times.
While DevOps is often called a methodology or an approach, one should understand that DevOps brings a change in the organization’s culture. Due to the new advantages, one can roll off the products and better the existing products as the feedback is enabled with DevOps platforms. The perennial deployment and improvement are termed CI/CD (Continuous Improvement and Continuous Development). This is one of the essential principles of DevOps.
As improvement is always in the picture, testing and rectifying errors is a given as bugs must be hammered out. This brings forth the requirement for swift testing, and one principle that keeps DevOps ticking is automatic testing. This testing mode doesn’t even require manual testing as bugs are detected by automatic testing, and it lends the chance to developers to fix bugs swiftly. The developers can also subject the project to load testing, giving insights into how the program will function under severe circumstances.
With this, we have covered the principles of DevOps. To sum it up, CI, CD, and automatic testing are the fundamental principles of DevOps. CI provides the inputs to the project members regarding the prevalent issues with the code, and the problems commonly expected in the initial stages are detected and fixed. Automatic testing creates quality issues and allows the developers to fix the bugs. Finally, the final or iterative update will be easily deployed with CD. Now, with the principles summarized, let’s dig into the advantages of DevOps.
