How Linkerd Helped bink Partner up with Barclays

Mark Swarbrick, Bink's Head of Infrastructure, shares how Linkerd gave the fintech startup the confidence to partner up with Barclays and serve millions of customers in the UK. Around 2016, the Bink infrastructure team started containerizing their apps. Not long after they migrated to the cloud and moved their apps onto Kubernetes. Still in the early days, they experienced issues with the cloud's unstable networking infrastructure, leading to multiple issues including huge amounts of random TCP disconnects, UDP connections just going missing, and other faults. After a little research, they gave Linkerd a try and, lo and behold, as soon as they started experimenting with it, network faults caused by the instabilities dropped significantly. The timing could not have been better. The team was just starting conversations with Barclays and Linkerd's metrics allowed them to monitor their SLOs and agree to the bank's ambitious latency and success rated based SLAs.
