๐Ÿ”Š Noisy Neighbor Simulation
๐Ÿ’ก What is Noisy Neighbor? When one tenant consumes excessive resources (CPU, I/O, connections), it can degrade performance for other tenants. Key insight: Logical isolation (separate DBs/collections) does NOT prevent thisโ€”only hardware isolation via sharding truly separates tenants onto different physical servers.

๐Ÿ“Š Current Strategy: Database per Tenant ๐Ÿ›ก๏ธ HIGH ISOLATION
With separate databases per tenant, each tenant has dedicated resources. A noisy neighbor cannot impact other tenants because they operate on completely isolated database instances.
