Old School Banks vs Cloud Native, API First UK Banks

UK banking has two distinct cohorts: legacy institutions migrating their APIs onto new infrastructure, and cloud-native challenger banks that built API-first from day one. The performance and reliability differences between them are measurable and significant.

This video uses data from APIContext's Open Banking monitoring to compare how these two groups actually perform, where the legacy institutions are closing the gap, and what the data says about the trajectory of UK Open Banking API quality.
