| Goal: Provide a unified multi-cloud management platform that abstracts cloud provider differences, enables intelligent workload placement based on cost, performance, and compliance requirements, optimizes spending across providers, enforces regulatory policies, and orchestrates seamless cross-cloud failover. |
| |
| Constraint: Workload placement decisions must evaluate at least 3 cloud providers before selection |
| Constraint: Cost data must be refreshed at least every 15 minutes from all cloud providers |
| Constraint: Compliance policies must be enforced before workload provisioning |
| Constraint: Cross-cloud failover must complete within 5 minutes RTO |
| Constraint: Cloud credential rotation must occur every 90 days automatically |
| |
| Risk: Cloud provider API rate limiting causing management plane degradation |
| Recovery: Implement exponential backoff with jitter; batch API calls where possible |
| |
| Risk: Data residency violation from incorrect workload placement |
| Recovery: Compliance policy engine validates placement before provisioning |
| |
| Risk: Cost overrun from unoptimized resource allocation across clouds |
| Recovery: Real-time cost monitoring with budget alerts at 80% and 100% |
| |
| Risk: Cross-cloud network latency degrading distributed application performance |
| Recovery: Cloud interconnect awareness in placement decisions |
| |
| Risk: Vendor lock-in from provider-specific service dependencies |
| Recovery: Enforce abstraction layer usage for all cloud services |
| |
| Risk: Credential compromise across multiple cloud accounts |
| Recovery: Zero-trust credential management |
