How To Keep Your Mission-Critical Cloud Workloads Running
InfoWorld, Thursday, September 3rd, 2026
A primer on the four pillars of cloud high availability: clustering, replication, failover and DR design.
This primer breaks cloud high availability into four components: clustering, data replication, failover and disaster recovery planning.
It recommends software-based SANless clustering to remove single points of failure in distributed environments where shared storage is not an option.
Real-time synchronization between nodes is what lets applications fail over automatically without manual intervention or data loss. Geographic separation between primary and DR sites, paired with asynchronous replication, protects against regional incidents while also enabling rolling patches and maintenance without service interruption.
