REFERENCE ARCHITECTURE

Multi-region active-active

Compute replicas across continental Zones, Gateway geo-routing, asynchronous or synchronous Datastore replication — Business and Enterprise tiers.

When to use

Contractual SLA above single-region offerings.
Global user base requiring low latency on multiple continents.
Documented BCDR with tested failover runbooks.

When to avoid

Single-country audience — multi-zone is lower cost.
MVPs and pre-product-market-fit experiments.

Design notes

Replication modes

Business: async replication (RPO seconds). Enterprise: sync quorum (RPO zero, higher write latency).

Gateway geo-routing

Gateway directs clients to the nearest healthy Zone. Health checks drive automatic failover.

Engagement

Multi-region designs are reviewed by Tesserra engineering before production cutover.

Microservices on private Fabric

Multiple Compute services on an isolated Fabric network, public ingress via Gateway, per-service Datastores and Autoscale policies.

Single-region web application

Production-ready pattern for SPAs, e-commerce, and public APIs — Compute, Datastore, Gateway, Sentinel, and Insight in one region.

Secure edge ingress

Defense-in-depth at the perimeter — Sentinel WAF, Gateway TLS termination, Fabric isolation, and Insight security monitoring.
