DevOps Case Studies


This is a bank of case studies on DevOps to help those tasked with implementing CI or CD. It can be a reality for organisations large and small independent of sector and technology. Because Daysha is focused on larger indigenous organisations our case studies are more oriented towards financial institutions with legacy technologies.

This material has been assembled over the last 2 years by the team at Daysha through attendance at meet up’s in Dublin and London, conferences in Europe and the US and through interactions with our various technology partners.

In total if you were to consume this content you would need of 4-6 hours to digest all the material. Many of the presentations are no less than 30-40 minutes.

More probably you will want to save this page as a bookmark and return here as you need more information.

Notes from meetings are available as word files. If you would like this material, please email us and we will send it on.

The content is ordered by growing maturity in DevOps.

Companies that are starting their journey are near the top. Those that are fully implemented/using microservice and thinking about dynamic auto provisioning etc.  are nearer the bottom.

1. Standard Bank discover DevOps

This is a story about a bank that grew frustrated with the pace of delivery from IT and decided to accelerate their journey to production through faster release cycles. There are a total of 6 blog articles outlining how they fast tracked their way to DevOps through piloting.

Since this blog Standard Bank have internet banking applications in a continuous delivery pipeline. They also have a further 3 projects adopting the practices. There is a white paper from Chef on the fastrack approach. Please email me for this.

2. IG’s DevOps 4 year journey

An online financial investment trading application that has applied DevOps to four different projects, including a legacy system that was quite fragile. The first presentation made by Joe McKevitt focuses on the incentive for people to buy into the processes and how their 4-year journey panned out. It includes some interesting insights into developing a community of best practice and engaging partners in the process. There is interesting content on Joe’s personal motivations that will resonate with all IT professionals.



The second presentation (below) is given by Gustavo Elias, the person who led the legacy system project at IG. This is aimed at a more technical audience.



3. Just Eat’s DevOps since 2010

This is a mature DevOps team working at the online food retailer that doesn’t produce any food! They scaled from 20 to 200 people; moved from Denmark to London in 2010; and put a CD process in place over the last 6 years. This team didn’t have a ‘legacy’ as such – their software processes up to 1200 food orders per minute. On route to a double digit features per day release cycle they migrated from data centre to AWS cloud.
