Multi-Cloud
Multi-cloud strategy uses multiple cloud providers, avoiding vendor lock-in, leveraging each cloud's strengths, and improving disaster resilience.
Purpose
Avoid vendor lock-in and single points of failure, leveraging each cloud's best services.
Mechanism
Abstract cloud differences with IaC (Terraform) + containers (K8s). Each cloud runs an independent K8s cluster with unified CI/CD. Data synchronization and cross-cloud networking remain challenges. Added cost and complexity require trade-offs.
Use cases
- Vendor neutrality
- Disaster resilience
- Cloud strategy
