Monzo Bank has launched Monzo Stand-in, an independent backup solution hosted on Google Cloud Platform (GCP) that maintains vital banking operations during applications and AWS outages. Unlike traditional mirrored backup systems, which often lead to dependencies and risks during failures, Monzo Stand-in operates autonomously using its own infrastructure, minimizing the chance of concurrent failures. It follows an eventual consistency model to manage data, allowing transactions to be recorded independently and reconciled later, thereby prioritizing availability and reducing operational costs to just 1% of the primary deployment.
Monzo Bank has introduced Monzo Stand-in, an innovative backup system that allows critical banking operations to persist during AWS outages, prioritizing software independence.
By ensuring that Monzo Stand-in operates with its own infrastructure and mechanisms, the bank reduces risks related to shared code and dependencies, minimizing failure chances.
