3. Workload Decision Framework
Clear, actionable rules on when each family wins based on workload profile, runtime language, and licensing boundaries.
Recommended:M7gd
When: Elasticsearch, OpenSearch, Kafka, or ClickHouse data nodes
Why: Extremely fast local disk operations bypass EBS network bandwidth constraints.
