Defining DevOps: differences between DevOps software approach and traditional IT
In a previous article, we discussed topics such as ‘What is DevOps?’ and “What are the benefits of implementing the DevOps set of practices?”. It’s about time we give you an extensive guide on how to transition to DevOps. But what are the differences between the DevOps and traditional IT approach and why statistically DevOps is more preferred by companies worldwide?
- The efficiency of development cycles: From big to micro
Traditional IT often plans big releases, which are much riskier due to the amount of code involved. When working in longer cycles with infrequent releases things can often become complex quite quickly and overall they are an inefficient way of working.
DevOps runs with smaller and more frequent releases that are easier to test and fix if needed– making the releases much less risky. Thus DevOps enables your business to quickly respond to any emerging customer needs or new market changes.
- Scheduling: Centralized to Continuous
Traditional IT mainly uses planning and scheduling systems to manage development. There are usually a lot of changes to the SDLC, making scheduling a challenge to execute properly.
DevOps revolves around smaller but continuous releases built on automation from dedicated teams. This makes the schedules much easier. Less planning allows you to increase the visibility of your team’s time. Moreover, by having a single dedicated team, you’ll be able to synchronize more effectively rather than having to schedule different employees in different roles.
- Transform High-Risk Events into Non Events
Within Traditional methods, releasing software into production hides a huge risk. It consists of bugs, escalations, and constant error resolution. The process is thus tightly administered from all parts of the organization. Have you ever seen developers locked in the office for days before and after a big launch?
DevOps methodology, on the other hand, make the release of software as non-event as possible. DevOps engineers reduce the risks by daily integration of code, automation testing, and ensuring all environments are in sync. Basically, they only integrate code from one stage to another once they are sure it would work in production. This ensures that all new features will move to production much faster and efficiently.
- Organization: Having Dedicated Cells
Traditional IT is organized around skill-centric silos. In a typical environment, a change has to go through at least a couple of silos before it gets to the end user.
DevOps also operates in silos but the teams are arranged in so-called “cells” of dedicated cross-functional teams. They are focused on only one application. It represents a self-sufficient cell of developers, testers, and operators, and an idea can move from one stage to another without hand-offs, focuses the whole team on the end goal, and promotes the “shift left” thinking.
- Culture: We mustn’t Fail vs. We should Fail Early
Traditional IT’s first priority is to do no harm to the business or basically prevent failure. And yet despite all efforts, this tactic presents bad outcomes: infrastructure issues cause huge delays, new projects are delivered late, and new features are often pulled back due to issues with quality.
DevOps also tries hard to maximally reduce risks but is well aware that issues are going to happen. That’s why instead of trying to eliminate failure, they prefer to fail small, early and recover promptly. The infrastructure and processes are built around this mantra. All of the above-mentioned: test-driven development, automation, daily code integrations, small but frequent release sizes, and cell structures, all contribute to this mindset.
Step-by-Step Guide for Starting out with DevOps
DevOps is not just a toolset, but rather a mix of cultural, development, and operational changes. As expected, transforming your company’s culture and operational model is not something done overnight. Every key change should be considered for quite some time, carefully thought out, and mapped out in a highly detailed manner. So let us give you an overview of the steps you need to take in order to successfully embrace the DevOps methodology and fully reap all of its benefits.
- Craft a DevOps transformation roadmap
To adopt DevOps, create a roadmap to sketch out how to start with DevOps in a step-by-step manner. Your roadmap should tackle all questions concerning your business transitioning to DevOps methodologies such as budgets, regulations within your industry, costs, teams, culture, talent, operations, and processes. Most importantly, this roadmap should include the exact expectations and KPIs, which could of course be changed in time, but still, they would act as guidelines and validation checkpoints for your successful transitioning. A DevOps roadmap enables an organization to map its actions upfront.
A successful DevOps migration is not a one-time project. You should be prepared to update the content as your business advances on its DevOps journey.
- Choose your right DevOps tool stack
Critical to starting DevOps is to choose a toolchain, but there’s no universal best practice for this step. By “DevOps toolchain,” we mean all the tools your team employs to manage the development, delivery, and maintenance of an efficient software development process.
A good DevOps toolset is one that is best aligned with organizational and industry-specific requirements. Thus the right tool stack will ease complex tasks and support team members to complete projects quicker and with less manual effort.
DevOps toolchain selection usually happens with a good understanding of the basic DevOps practices and how each tool executes them. Organizations typically have two options: an all-in-one DevOps tech stack or one that’s custom to their needs. It is vital to select the right approach, as the decision will shape the DevOps practice. The all-in-one DevOps toolchain is an ideal solution for companies that are just starting with DevOps or for teams that immediately initiate a project.
DevOps encompasses different phases. Even though processes may vary depending on the flow, the core principles remain the same. Review our DevOps tool cheat list below as a piece of good advice is to be guided through a basic DevOps pipeline and get an overview of some of the most popular and efficient tools for each phase.

- Invest in a good foundation
You need a solid foundation to be able to gain the best results and achieve short and long-term goals. That requires investing in the right DevOps technologies and tools. With the right infrastructure in mind from the beginning, you can build just about anything.
As part of this mindset, you can onboard key business partners – DevOps providers, managed services providers, cloud providers, hosting providers, etc. What you should be looking for is a partner that can help you maximize deployment flexibility, security, and overall performance.
- Embrace the DevOps cultural transformation
DevOps disrupts some organizational and political structures as all teams start operating as a whole. To meet these challenges, make sure you foster a befitting DevOps cultural transformation with the following focal points:
- Enforce Responsibility and Accountability.
- Promote Communication and Collaboration between developers, operations, QA, and security teams for workflows.
- Invest in training your teams: prepare your company for continual learning and improvement.
- Automate everything
Many organizations consider automation too big of a risk to take. To eliminate this fear, start small and adopt a transparent approach to DevOps automation.
Review weak links, establish priorities, and set automation goals. Don’t automate every process in every possible workflow at once. Let’s say you start with automated testing: you can first focus on testing software, then focus on security testing. Although automated testing can’t replace human testers, this approach may help you learn how much automation can improve employee efficiency. Freeing your workforce from having to perform daily repetitive, manual, time-consuming tasks can amaze you with innovation, freshness, and better concentration on the core goals. This creates an opportunity to explain the business reasoning and align your work with automation.
- Measure Metrics: use analytics and collect data
You must find a way to track your transition to DevOps, measure the progress, and be ready to implement changes if you deviate too much from the roadmap or the results ain’t satisfactory. For example, you may take the current metrics of different stages of the SDLC (for example, time taken to develop, test, etc.) and compare them with the metrics obtained after the implementation of DevOps practices.
By evaluating the velocity, costs, or quality of software releases, you’ll be able to assess whether your DevOps team is on the right track. Moreover, you may look into customer satisfaction metrics to gain insights into the whole performance.
Venture into your DevOps journey
As we previously discussed, adopting the DevOps approach to software might help you overcome many challenges and surprise you with immense benefits. You may not yet be fully aware of exactly how DevOps can be implemented for your company or exactly what advantages it will provide you with. So let’s look at examples of successful adoptions of DevOps by world-renowned successful companies, as well as appropriate ways to take the first steps towards this digital transformation.
