Redis tier capabilities

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.

Important: Basic Tier instances undergo a cache flush during maintenance or any instance restart, such as the restart caused by scaling your instance.

If your application cannot tolerate a Redis instance cache flush, consider using a Standard Tier redis instance to prevent data loss.

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
Stackdriver Monitoring	Yes	Yes
Scale memory¹	Yes	Yes
Cross-zone replication	No	Yes
Automatic Failover	No	Yes

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 Scaling Behavior.
² During maintenance, Basic Tier instances undergo a full cache flush and Standard Tier instances undergo a failover. For more information see Maintenance policy.
