What are the Advantages of DevOps?
DevOps was introduced into the IT world about a decade ago. Since then, due to its inherent advantages, it has become the by-word of IT Managers to improve workplace efficiency and infuse a sense of team spirit.
How did this come about by the introduction of DevOps? Before DevOps, the Development and Operations teams of an organisation worked in isolated Silos, with only what was perceived to be, essential communication between the two. This lead to longer development to deployment loops and the product would have a higher than acceptable failure rate at launch. When a glitch cropped up, the blame game between the teams would crop up, leading to a much longer time between detection and solution.
These bottlenecks forced a rethink. Why not combine the efforts of both teams? The adoption of DevOps lead to a new culture at the work spot where both teams functioned as one. This unleashed the combined synergy of the entire group as a whole.
What are the long term benefits of introducing the DevOps culture in the workplace?
• Faster deployment of new systems and apps
Once the organisation has adopted DevOps, it has to take steps to achieve the next level of deployment. The new systems can be introduced with greater enhancement, at the same time upping the efficiency quotient. The result is that deployment not only becomes easier, it happens in a shorter time span.
• Increases agility
When a business is agile, it makes faster business decisions. When DevOps is introduced, even large organisations can scale up as required, so as to make the organisation more Agile. This win-win situation leads to a much higher level of business efficiency with cost reduction.
• DevOps and cost reduction
DevOps helps automate repetitive tasks. Once a task is automated, errors are negligible. Taking the example of regression and performance testing a small change is brought about in a rapid manner. By automating the process to make frequent back-ups and rollovers, the entire process becomes stable and robust. When automation is introduced into the process, man power can be saved, leading to lower input costs.
• Silos are eliminated
Development and Operations, though part of the same organisation, worked in isolated silos. Innovation teams worked in an opaque, secretive fashion. Basically, in the same organisation, the left hand did not know the right hand was doing, though. This lack of interaction and communication between Development and Operations teams, lead to longer development to launch cycles as well as a higher than acceptable failure rates at launch.
DevOps changed such a mind set and introduced a culture in which both teams worked together as a whole and interacted right from the innovation stage. The DevOps synergy, lead to faster launches of apps, with much lesser glitches.
In the IT world, different barriers will be encountered and DevOps eliminated the linear approach in favour of the combined approach of both teams. The frequent interaction, gave the business more agility to take timely decisions to meet market trends and customer expectations.
• Reduced development cycle time
The DevOps culture of collaboration and communication helped to an automatic improvement of development cycles. The reduction in failure rate at launch too added to cost savings as well as better user experience. With DevOps, apps were not only developed faster, but at lesser cost due to automation and efficiencies in the system. DevOps is a win-win situation for the entire organisation.
• Continuous service delivery
DevOps causes the reduction in development cycles. Codes could be released into production at a faster rate. To achieve continuous delivery, the entire software release process is automated. Every revision made to the app will auto-trigger an automated flow of events. This auto-triggered flow, will build, test and stage the update. However, the final decision to launch is triggered by the developer.
• DevOps helps eliminate defects
In an ecosystem where applications are developed and released, glitches and bugs are the worst enemy. Before DevOps, when the app was launched, the glitches could even make the entire system crash, leading to irate customers. With DevOps having all teams on the same page, defects etc. became next to negligible. Fool proof techniques could be introduced to handle any defect that shows up.
There are so many aspects to DevOps which throws up challenges to keep IT professionals stimulated. A DevOps career gives a sense of a job ‘well done’ at all times. If this has aroused your curiosity and you wish to embark on such an exciting career, go in for proper training and certification.
