![]() You can choose an Availability Zone for deployment, and Amazon Redshift will deploy your cluster in the chosen Availability Zone based on the subnets provided. For a Single-AZ deployment, Amazon Redshift selects the subnet from one of the Availability Zones within a Region and deploys the cluster there. You can configure your cluster subnet group to add subnets from different Availability Zones that you want Amazon Redshift to use for cluster deployment.Īll Amazon Redshift clusters today are created and situated in a particular Availability Zone within an AWS Region and thus called Single-AZ deployments. When you launch a cluster, Amazon Redshift either creates a default cluster subnet group automatically or you choose a cluster subnet group of your choice so that Amazon Redshift can provision your cluster in one of the subnets in the VPC. The cluster subnet group includes information about the VPC ID and a list of subnets in your VPC. Multi-AZ deploymentĪmazon Redshift requires a cluster subnet group to create a cluster in your VPC. We also provide a walkthrough on how to test fault tolerance of an Amazon Redshift Multi-AZ data warehouse and monitor queries in your Multi-AZ deployment. We provide a walkthrough of how to perform a Multi-AZ deployment for an Amazon Redshift cluster using the AWS Management Console. In this post, we show how to configure an Amazon Redshift Multi-AZ deployment in multiple Availability Zones. In situations where there is a high level of concurrency Redshift will automatically leverage the resources in both AZs to scale the workload for both read and write requests using active-active processing. A Multi-AZ deployment is intended for customers with business-critical analytics applications that require the highest levels of availability and resiliency.Ī Redshift Multi-AZ deployment leverages compute resources in multiple AZs to scale data warehouse workload processing. Multi-AZ deployments support running your data warehouse in multiple Availability Zones simultaneously and can continue operating in unforeseen failure scenarios. Although many customers benefit from these features, enterprise data warehouse customers require a low RTO and higher availability to support their business continuity with minimal impact to applications.Īmazon Redshift now supports Multi-AZ deployments (Preview) for provisioned RA3 clusters. Amazon Redshift also supports automatic backups that can be used to recover a data warehouse, automatic remediation of failures, and the ability to relocate a cluster to another Availability Zone without changes to applications. Amazon Redshift RA3 instance types store their data in Redshift Managed Storage (RMS), which is backed by Amazon Simple Storage Service (Amazon S3), which is highly available and durable by default. Amazon Redshift is a cloud-based data warehouse that already supports many recovery capabilities to address unforeseen outages and minimize downtime. Data warehouse workloads are increasingly being used with business-critical analytics applications that require the highest levels of availability and resiliency. If you are a database developer, the Amazon Redshift Database Developer Guide explains how to design, build, query, and maintain the databases that make up your data warehouse.Amazon Redshift is a fully managed, petabyte scale cloud data warehouse that enables you to analyze large datasets using standard SQL. If you are a first-time user of Amazon Redshift, we recommend that you begin by reading the Amazon Redshift Getting Started Guide. You can focus on using your data to acquire new insights for your business and customers. Īmazon Redshift manages all the work of setting up, operating, and scaling a data warehouse: provisioning capacity, monitoring and backing up the cluster, and applying patches and upgrades to the Amazon Redshift engine. For a summary of the Amazon Redshift cluster management interfaces, go to Using the Amazon Redshift Management Interfaces. In this reference, the parameter descriptions indicate whether a change is applied immediately, on the next instance reboot, or during the next maintenance window. Note that Amazon Redshift is asynchronous, which means that some interfaces may require techniques, such as polling or asynchronous callback handlers, to determine when a command has been applied. It contains documentation for one of the programming or command line interfaces you can use to manage Amazon Redshift clusters. This is an interface reference for Amazon Redshift.
