This page describes the differences between the available Redis tiers.
Memorystore for Redis supports Basic and Standard Tiers. The Basic Tier is best suited for applications that use Redis as a cache and can withstand a cold restart and full data flush. Standard Tier instances provide High Availability using replication and automatic failover.
|Specifications||Basic Tier||Standard Tier|
|Description||Provides a cache with no replication||Provides redundancy and availability using replication|
|Max instance size||300 GB||300 GB|
|Max network bandwidth||12 Gbps||12 Gbps|
¹ Basic Tier instances experience a downtime and a full cache flush during
scaling up or down. Standard Tier instances experience minimal downtime and loss
of some unreplicated data during the scaling operation. For more information, see
2 During maintenance, Basic Tier instances undergo a full cache flush and Standard Tier instances undergo a failover. For more information see Maintenance policy.
