    The time it takes for the failover to complete depends on the database activity and other conditions at the time the primary DB instance became unavailable. Failover times are typically 60-120 seconds. However, large transactions or a lengthy recovery process can increase failover time. When the failover is complete, it can take additional time Redis Cluster is a way to use a group of Redis instances running together and automatically sharding data between themselves. The failover mechanism is the same as a normal single Redis instance where the master node has a replica node that can ta...

    How To Manually Failover Sql Cluster The 2-node Windows Server Failover Cluster (WSFC) running my SQL Server failover clustered instance suddenly went offline. It turns out that my quorum disk. Best DR strategy for MS SQL Failover Cluster (closed) auto failover from PROD to DR because management approval will be required, I will failover manually. 11.2 — Select any of the nodes, click on “Action” and select “Failover primary”. Read the message to understand what's going on, and then click “Continue”. One of the replicas will become the new master, and the number of replicas per master will be restored.

    Previously we posted a blog discussing Achieving MySQL Failover & Failback on Google Cloud Platform (GCP) and in this blog we'll look at how it’s rival, Amazon Relational Database Service (RDS), handles failover. We will also look at how you can perform a failback of your former master node, bringing it back to its original order as a master. I'm working on an API that is using Redis which is hosted on ElastiCache with three nodes (one primary, two replicas). For some reason over the weekend, the primary was switched to node 002 (from 001) which caused READONLY errors for my application when it tried to send messages to Redis.. Is there any reason why this should ever happen without doing it manually?

    In this post lets explore how to architect and create a Highly Available + Scalable Redis Cache Cluster for your web application in AWS VPC.

    Asynchronous replication mechanisms are used to keep the read replicas synchronized with the primary. Applications can read from any node in the cluster. Applications can write only to the primary nodes. All of the nodes in this Redis cluster must reside in the same region. You cannot manually promote any of the replica nodes to primary.

    In certain cases, ElastiCache for Redis detects and replaces a primary node. These cases include certain types of planned maintenance and the unlikely event of a primary node or Availability Zone failure.

    This is the most affordable failover option, because deployments are completely free. Simply create a clone of your production deployment and save it as a backup deployment. If the primary zone ever fails, all you will have to do is manually launch the backup deployment.
