Isolation

Momento Cache isolates workloads at the Capacity Pool boundary. A pool is dedicated to your account and does not share capacity with other tenants, so there are no cross-tenant noisy neighbors at the pool level.

Isolation is per pool, not per database​

Databases on the same pool share that pool's compute and memory. They are therefore subject to noisy-neighbor effects from each other. A Database that drives heavy load can affect others on the same pool.

Plan your layout accordingly:

  • Put workloads that must have sufficient resources onto dedicated pools.
  • Pack workloads that tolerate sharing onto one pool to use its capacity efficiently.

Guidance​

  • Use a dedicated pool for a latency-sensitive or business-critical workload.
  • Group development, test, and low-traffic workloads onto a shared pool to control cost.
  • Size a shared pool for the sum of its Databases' peaks, with headroom.
