Problem

The system is designed for single-node deployment only:

Limitations:

  • No support for multiple clusters
  • No federation between clusters
  • No cross-cluster service discovery
  • No workload migration
  • No disaster recovery between clusters
  • Single point of failure

Proposed Solution

Design multi-cluster and federation capabilities:

Phase 1: Multi-Cluster Model

  • Cluster registration and discovery
  • Cluster health monitoring
  • Cluster metadata and labels
  • Cluster affinity rules

Phase 2: Federation Layer

  • Cross-cluster service discovery
  • Federation API
  • Workload scheduling across clusters
  • Federation policies (replication, sharding)

Phase 3: Data Synchronization

  • State replication between clusters
  • Event propagation across clusters
  • Conflict resolution strategies
  • Eventual consistency models

Phase 4: Advanced Features

  • Workload migration
  • Disaster recovery automation
  • Cluster scaling
  • Edge deployment support

Acceptance Criteria

  • Multi-cluster registration working
  • Cross-cluster service discovery
  • Federation API functional
  • Workload scheduling across clusters
  • State synchronization
  • Conflict resolution
  • Workload migration capability
  • Disaster recovery workflows
  • Multi-cluster tests
  • Documentation complete

Priority: Medium
Type: Architecture/Feature
Estimated effort: 5-6 weeks

Dependencies: ARCH-002, ARCH-003, ARCH-005
