# The Space-Based Architecture Paradigm ## When To Use - High-traffic applications needing elastic scalability - Systems requiring in-memory data grids ## When NOT To Use - Low-traffic applications where distributed caching is overkill - Systems with strong consistency requirements over availability ## When to Employ This Paradigm - When traffic or state volume overwhelms a single database node. - When latency requirements demand in-memory data grids located close to processing units. - When linear scalability is required, achieved by partitioning workloads across many identical, self-sufficient units. ## Adoption Steps 1. **Partition Workloads**: Divide traffic and data into processing units, each backed by a replicated data cache. 2. **Design the Data Grid**: Select the appropriate caching technology, replication strategy (synchronous vs. asynchronous), and data eviction policies. 3. **Coordinate Persistence**: Implement a write-through or write-behind strategy to a durable data store, including reconciliation processes. 4. **Implement Failover Handling**: Design a mechanism for leader election or heartbeats to validate recovery from node loss without data loss. 5. **Validate Scalability**: Conduct load and chaos testing to confirm the system's elasticity and self-healing capabilities. ## Key Deliverables - An Architecture Decision Record (ADR) detailing the chosen grid technology, partitioning scheme, and durability strategy. - Runbooks for scaling processing units...
