Agile is a set of values and principles about how to produce i.e. develop software. For Example,if you have some ideas and you want to turn those ideas into working software, you can use the Agile values and principles as a way to do that. But, that software might only be working on a developer’s laptop or in a test environment. You want a way to quickly, easily and repeatably move that software into production infrastructure, in a safe and simple way. To do that you need DevOps tools and techniques.Though the implementation of DevOps is always in sync with Agile methodologies, there is a clear difference between the two. The principles of Agile are associated to seamless production or development of a piece of software. On the other hand, DevOps deals with development, followed by deployment of the software, ensuring faster turnaround time, minimum errors, and reliability.
Much has been written about what DevOps is, but not a lot has been said about what it can do for an organization. The trending software development approach has many quantifiable technical and business benefits, including shorter development cycles, increased deployment frequency, and faster time to market. But because it relies so heavily on increased communication, collaboration, and innovation, it can also be a catalyst for cultural change within an organization.
1.ETSY
Etsy is a peer-to-peer e-commerce website focused on handmade or vintage items and supplies, as well as unique factory-manufactured items.For its first several years, Etsy struggled with slow, painful site updates that frequently caused the site to go down. In addition to frustrating visitors, any downtime impacted sales for Etsy's millions of users who sold goods through the online marketplace and risked driving them to a competitor.
With the help of a new technical management team, Etsy transitioned from its waterfall model, which produced four-hour full-site deployments twice weekly, to a more agile approach. Today, it has a fully automated deployment pipeline, and its continuous delivery practices have reportedly resulted in more than 50 deployments a day with fewer disruptions. And though Etsy has no DevOps group per se, its commitment to collaboration across teams has made the company a model of the DevOps framework.
2.Fidelity Worldwide Investment
Fidelity Worldwide Investment had several business units developing software applications and was burdened with legacy release processes that placed huge demands on its teams. Apps were deployed manually across hundreds of servers, with each app requiring customization. Manually introduced errors frequently broke the process.When it came time to develop a critical trading application with a firm launch date, the organization knew its error-prone manual process would jeopardize the project. Fidelity used the opportunity to embrace a DevOps approach and implement an automated software release framework that would enable it to meet the rollout schedule.That solution resulted in more than $2.3 million per year in cost avoidance for that app alone. Since then, the Fidelity team has automated the release of dozens of applications, reducing release times from two to three days to one to two hours and decreasing test-team downtime. The process has also made it easier to display regulatory compliance and has enabled predictable release schedules that stakeholders can rely on.
3.Sony Pictures Entertainment's Digital Media Group
(DMG) faced significant challenges delivering a software system to manage entertainment assets for end users. Manual processes and other hurdles typically resulted in a months-long delay between completion of software development and delivery.To smooth out this "last mile," DMG implemented an automated cloud delivery system composed of open source tools and SaaS solutions. Since adopting a continuous delivery model, DMG has cut down its months-long delivery time to just minutes. This allowed developers to focus on adding features and reduced idle resources and associated costs.
