Amazon Redshift is introducing Multi-AZ deployments (Preview) that support running your data warehouse in multiple AWS Availability Zones (AZ) simultaneously and continue operating in unforeseen failure scenarios. A Multi-AZ deployment is intended for customers with business critical analytics applications that require the highest levels of availability and resiliency to AZ failures.
A Redshift Multi-AZ deployment allows you to recover in case of AZ failures without any user intervention. A Redshift Multi-AZ deployment is accessed as a single data warehouse with one endpoint and helps you maximize your data warehouse performance by distributing workload processing across multiple AZs automatically. You are not required to make any application changes to maintain business continuity during unforeseen outages.
Multi-AZ deployment for Amazon Redshift RA3 clusters is available in Preview, and you can use it in the following AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Tokyo), Europe (Ireland) and Europe (Stockholm). To get started, you can provision an Amazon Redshift Multi-AZ deployment which will be automatically created on the PREVIEW_2022 track. Please note preview features are provided primarily for evaluation and testing purposes, and should not be used in production systems or with production data. For preview terms and conditions, see Beta Service Participation in AWS Service Terms.
