Clusters for Microsoft Azure High Availability

High Availability Clustering Solutions for Microsoft Azure

What is Microsoft Azure Clustering?

Microsoft Azure clustering ensures high availability protection for critical applications running in Azure environments by eliminating single points of failure. In an Azure cluster environment, two or more nodes in Azure are configured in a failover cluster using clustering software. The critical application is run on a primary node in the cluster. If clustering software detects an application operation failure, it orchestrates a failover of the application operation to secondary node(s) in the cluster.

Microsoft Azure High Availability with SIOS DataKeeper

For customers running critical Windows applications in Windows Server Failover Clustering (WSFC) environments, SIOS DataKeeper Cluster Edition is the first Azure certified high availability and disaster recovery solution in the Azure Marketplace. It provides efficient data replication and seamless integration into Windows Server Failover Clustering environments for high availability clusters without the need for costly shared storage. Simply add SIOS DataKeeper to a WSFC environment and it synchronizes local storage using highly efficient block-level replication, making it appear to WSFC as traditional shared storage. IT teams use SIOS DataKeeper to continue to use familiar WSFC in the cloud without the cost and complexity of a SAN or other shared storage.

SIOS LifeKeeper

While cloud providers offer high availability service levels for their hardware, they do not cover software-related downtime. Critical critical applications, databases, and ERPS, such as SQL Server, Oracle Database, SAP, HANA companies need 99.99% uptime at the application and data level using SIOS LifeKeeper. SIOS LifeKeeper for Linux and SIOS LifeKeeper for Windows provide application-aware HA/DR for complex, critical applications in Azure for reliable easy-to-manage clustering environment.

SIOS LifeKeeper for Linux is the only solution that provides a comprehensive range of Linux clustering, protecting applications in SUSE Linux, Red Hat Linux, Oracle Linux, and Rocky Linux clustering environments. SIOS LifeKeeper for Windows provides reliable failover clustering for applications in Windows environments. SIOS LifeKeeper comes with unique SIOS application recovery kits that provide application-specific intelligence to automate configuration and management steps and ensure failovers happen in compliance with application-vendor best practices for maximum efficiency and reliability.

SIOS LifeKeeper is sold as part of the SIOS Protection Suite (for Windows and for Linux), a tightly integrated combination of high availability failover clustering, continuous application monitoring, data replication, and configurable recovery policies. SIOS Protection Suite includes SIOS LifeKeeper clustering software, SIOS DataKeeper replications software, and multiple Application Recovery Kits (ARKs) to protect your business-critical applications and data from downtime and disasters.
