Sarah Wells
I've been a developer for 15 years, leading delivery teams across consultancy, financial services and media. Over the last few years I have developed a deep interest in operability, observability and devops, and at the beginning of 2018, this led to me taking over responsibility for Operations and Reliability at the Financial Times.
Before that, I led work at the FT on building a semantic publishing platform, making it easy to discover and access all the FT’s published content via APIs in a common and flexible format. That project meant a focus on Go, microservices, containerisation, and how to influence teams to do the right things.

Featuring Sarah Wells
The FT’s content platform team put our first containers live in mid-2015 and migrated the rest of our services over by April 2016. At that point, we weren't using Kubernetes - and much of what we were using, we built ourselves.

Nudge theory: Influencing empowered teams to do the things that matter to you with Sarah Wells
Featuring Sarah Wells
Successful DevOps means empowering teams – “you build it, you run it” is a fine principle, but it means you need to let your teams make their own choices. But you still have things you want all teams to do, and you need to balance the benefits of the right technologies against the costs of...
