A UK-based digital bank moved its core banking platform to the cloud with a dedicated Javixor team, hitting 99.99% uptime through the migration and every day since.
Every month on the old infrastructure meant slower releases, rising hardware maintenance costs, and growing regulatory exposure from having no tested failover plan. A single extended outage could have triggered a formal regulatory review.
Ran old and new environments in parallel with gradual traffic shifting and automated data reconciliation between them.
Weeks 1-16Built monitoring and alerting that met the regulator's documentation standard for every system touching customer funds.
Weeks 4-20Automated the audit trail generation the compliance team previously compiled by hand for every release.
OngoingThe bank completed its core migration with no customer-facing downtime and passed its next regulatory review without a single finding related to the new infrastructure.
Measured continuously in the eight months since the migration completed.
The phased approach meant customers never experienced a service interruption during the migration itself.
Moving off colocated hardware to right-sized cloud infrastructure cut ongoing infrastructure spend by more than a third.
We told Javixor we could not have a single minute of customer-facing downtime during a core banking migration. They delivered exactly that, and our next regulatory review came back clean.
