You could be forgiven for assuming DevOps is the modus operandi only for big modern enterprises like Tesla and Uber, but this is not the case. DevOps builds on earlier approaches, such as Agile development and Lean methodology, by emphasizing the importance of collaboration between development and operations teams and the use of automation to streamline the software development process.
So, while the term “DevOps” is relatively new, the principles and practices that it encompasses have been in use for many years.
In a traditional waterfall model, the software development process is split into distinct stages, with each stage being completed before moving on to the next one. The development and operations teams work in separate silos, with little interaction between them until the end of the development process when the finished product is handed over to the operations team for deployment and maintenance.
Benefits of DevOps
In contrast, a DevOps model emphasizes collaboration and communication between the development and operations teams throughout the entire software development life cycle. The goal is to create a culture of shared responsibility for the success of the project, with both teams working together to ensure that the software is developed, tested and deployed quickly and efficiently.
DevOps also emphasizes automation, with the use of tools and processes to streamline the aforementioned project tasks. This automation helps to reduce the likelihood of errors and allows the teams to focus on higher-level tasks.
Overall, the key differences between DevOps and a traditional waterfall model are the emphasis on collaboration and communication, the use of automation and the focus on shared responsibility for the success of the project.
In short: Speed, time to market, agility and cost savings.
What’s Driving DevOps Transformation?
Any company, regardless of size, can release faster with DevOps. Look at the agile FinTech success stories; look at the generative AI success stories. In terms of cost savings too, it’s not ‘How much am I paying for 10 people, 20 people, 100 people…?’ From a DevOps standpoint, cost means penalties avoided from failing to release on time, project delays and project poor quality.
Overall, development practices are evolving. Some clients call DevOps ‘zero rework’ development, others refer to it as ‘shift-left development.’ Whichever term you prefer, the context is the same: They want faster release and to reduce duplication of work. The way to achieve ‘shift-left’ or ‘zero rework’ would be through DevOps transformation. All of the individual pillars of DevOps concern shifting left, causing them to release faster and achieve their cost optimization.
However you refer to it, DevOps is mainstream because of its scalability benefits, as well as the agility to react to unforeseen situations during development, QA or operations. This equates to competitive advantages and future-proofing.
Challenges of Implementing DevOps
Every business is different, but many of the challenges are the same. One of the main challenges is understanding your company’s specific blend of pain points on its road to DevOps transformation. Common challenges include:
Vision – DevOps is not a top-down initiative. The role of executives in DevOps is to define a vision; if the vision is not clear, you won’t have buy-in. You can have the best tools and technology but if you don’t have buy-in, then it won’t work.
Investment – DevOps is a change in every aspect of people, processes, technology and culture. You can’t just bring in this change with zero investment. It’s not unusual for costs to go up for the first couple of years after moving to DevOps because you’re transitioning from manual testers and normal developers to fungible team members that come at a premium. The cost advantage shows up after at least a year as rework goes down and the quality of release incrementally increases, leading to a better customer experience. So, it’s self-funded from the efficiencies it will bring in … but only if you persevere.
Celebrating Success – Too many people try to boil the ocean with DevOps transformation. This leads to frustration, misaligned teams and, eventually, poor results. If you start small with DevOps transformation, it soon shows its superiority as a business model. This inspires your leadership and your executive teams to see the benefit of DevOps and buy into it by osmosis rather than taking the word of that executive with a big idea and a big purchase order.
Culture and People – This is more than just a technology play. In fact, technology is the easy part. People, processes and culture all need to transform to implement DevOps. You need to move from a project to a product-based methodology. From a people perspective, you can’t bring in manual testers or manual validators to do DevOps. Any successful DevOps implementation has to get this right.
How to Implement DevOps: The Hub and the Spoke
Again, start small. You could start with only continuous integration and then move on to add continuous deployment. If you start over aspirationally, you are more likely to fail and go back to the old ways. As you expand DevOps gradually, you can follow the hub and spoke model.
In the hub and spoke model, the hub is a lean team responsible for setting up the tools, automation and best practices. The hub is responsible for defining what is to be executed. The spoke, on the other hand, is responsible for execution. The spoke is the extended team and their individual projects which they are responsible for executing.
The hub is also responsible for enablement by defining what processes, best practices, tools and pipelines should be used. Teams in the spoke will use the pipeline to promote their goal from development to QA, from QA to staging and from staging to production.
Next-Gen DevOps
The evolution of DevOps continues even for early adopters, especially with the introduction of AI and generative AI. How do you use AI to validate your requirements? How do you use AI to decide what infrastructure is needed and when? How can you use AI to optimize your test sets? Next-gen DevOps is about smarter DevOps and intelligent DevOps.
