Benefits of using DevOps while coding apps
Part of the job of coding and building apps is to deliver and sustain them in a proper fashion with the least of amount of overhead. Resources are normally limited, and time constraints are normally tight. Enter DevOps. Even if we want to call our processes as Agile, we still have the business side with needs to fulfil, such as profit margin and time to market playing against us. It is important that DevOps doesn’t fall into the myths of software development.
Under this typical scenario we want to be as effective as possible, having people focus on the critical tasks of the sprint, and not on base-level requirements to deploy an app such as setting up servers, fixing bugs due to incompatibility on environments, branch versioning, or managing equipment, licenses and network problems. This is where a proper DevOps environment comes handy, going in hand with Cloud, Flexibility of Infrastructure and Tools focusing on the processes of compile, deliver and integrate development.
From a traditional mindset-point-of-view, Agile pushes changes, while IT infrastructure limits changes. DevOps is an enabler that mixes the two worlds. Let’s see how your company can benefit from having a DevOps process and why:
BENEFITS OF USING DEVOPS
A survey from Puppet gave amazing results on how DevOps improves speed. Software development teams with a DevOps department deploy apps 200 times more frequently, with 2,000 faster lead times, and allowing a recovery of 24 times faster while having a great rate of 3x lower failure rate.
This is achieved by having infrastructured that’s easily available and provisioned on demand, for example by having cloud servers and solutions from services like Amazon, Azure or Google Cloud. Also, by allowing you to react fast to changes in technology by updating code on a weekly basis with as little errors as possible, thanks to the methods of CI/CD (continuous integration and continuous delivery).
You can think of DevOps more like an enabler than a requirement allowing you to accomplish your Agile goals in time.
The number one barrier that DevOps overcomes is cultural changes on process and deployment of software. The idea is to eliminate silos while developing code. Projects that implement DevOps practices get more done, plain and simple. With a single team composed of cross-functional members all working in collaboration.
Tools like Jenkins enable developers to frequently merge the code into a central repository hosted on cloud. Then it is verified by an automated build that takes seconds against a normal build on a local computer that can take hours. This lets teams find bugs much earlier in the development process and correct accordingly and make a synergy between coders, QA, IT and end-customer, making sure each person reaches their individual and team objectives.
Since customers are receiving frequent and timely updates, you can evaluate and test satisfaction early on. The shorter release cycles allow the collaborative team to direct the product in the direction needed leading to a tighter time to market and product match.
The greatest benefit that you can get from DevOps are improved defect detection, fewer deployment headaches and a decrease in rollbacks. Users compile and test on uniform environments on-server, avoiding the common phrase “it works on my computer, but it doesn’t on the customer’s side”.
At the end of the day problems will arrive, however, recovery time with DevOps is vastly reduced, allowing you to rollback versions as needed increasing or reseting servers from any location. Support for operations is reduced from a 24/7 team on site to a single person with connectivity to internet.
HOW DO WE GET THERE?
In the end, the DevOps culture inspires a performance-oriented team that fosters the sharing of risks. If you want to join this journey, the first thing to do is start thinking cloud, find somebody than can give you support to manage the cloud service and initial deployments, and implement the methodology with your developers. This process should take around 2 weeks for typical startup apps, and of course maybe a couple of months for existing products than run lots of modules. Most of the tools are free and open source the pain point is not from there. As I mentioned earlier, the critical route is to change culture and include DevOps resources in your budget and development plan.
