# Multi-Cloud Architecture Patterns
|
|
|
|
## Active-Active Regional Split
|
|
|
|
- Run customer-facing services in two providers for resiliency
|
|
- Use global DNS and traffic steering to shift load during incidents
|
|
- Keep shared data replicated asynchronously unless low-latency writes are mandatory
|
|
|
|
## Best-of-Breed Service Mix
|
|
|
|
- Analytics and ML on GCP
|
|
- Enterprise identity and Microsoft workloads on Azure
|
|
- Broad ecosystem integrations on AWS
|
|
- Oracle-centric databases and regulated transaction systems on OCI
|
|
|
|
## Primary / DR Pairing
|
|
|
|
- Keep primary infrastructure in the provider closest to operational expertise
|
|
- Use a second provider for cold or warm disaster recovery
|
|
- Validate RPO/RTO assumptions with regular failover exercises
|
|
|
|
## Portable Platform Baseline
|
|
|
|
- Standardize on Kubernetes, Terraform/OpenTofu, PostgreSQL, Redis, and OpenTelemetry
|
|
- Abstract cloud differences behind modules, golden paths, and service catalogs
|
|
- Document provider-specific exceptions such as IAM, networking, and managed database behavior
