Automatically replicate api calls to separate data centers

Abstract

Described herein are systems and methods for transparent resiliency to multiple data centers. The systems and methods depicted determine if an application programming interface (API) call is idempotent. If the API call is idempotent, the calls can be concurrently forwarded to multiple datacenters. If the API call is not idempotent, the calls can be sent to each of a multiple datacenters in turn until a response is received or timeout occurs. Automatically providing multi-region calls in synchrony provides a faster response time during data center or regional failures. Automatically providing multi-region calls in synchrony at the appliance server side, moves the logic out of the client and into a transparent and centrally managed service. This can allow business logic to focus on the core logic and not on logic to retry requests or manage the multi-regional aspect of a dependent service.
