Request Routing.
Build intelligent request routing that directs traffic to appropriate ABIS endpoints.
Request routing determines which backend handles each request. For ABIS custom APIs, routing decisions might depend on: request type, user tier, geographic location, or current load.
Implement routing at the API gateway level. This centralizes routing logic, enables A/B testing, and provides observability into traffic patterns.
Design for failure: if a primary route is unavailable, automatic failover to secondary routes maintains availability. Circuit breakers prevent routing to known-bad backends.
CONTENT-BASED ROUTING
Route based on request content: API version, operation type, payload characteristics.
LOAD-BASED ROUTING
Distribute traffic based on backend capacity. Prevent overload of individual instances.
GEOGRAPHIC ROUTING
Route to nearest datacenter for latency optimization. Respect data residency requirements.
FAILOVER ROUTING
Automatically route to healthy backends when primary is unavailable.
