What are High Availability Cluster Solutions for Microsoft Azure?
High availability cluster solutions are systems designed to ensure continuous operation of applications and services by minimizing downtime through redundancy and failover mechanisms. These solutions link multiple servers or nodes to work together, so if one node fails, others automatically take over without service interruption. They provide monitoring, load balancing, and automatic recovery features to maintain system reliability and performance. High availability clusters are critical for mission-critical applications requiring near-zero downtime, such as databases, web services, and financial systems. By reducing single points of failure, they help organizations meet stringent uptime and disaster recovery requirements.

Windows Server Failover Clustering
Microsoft
Failover Clustering in Windows Server (and Azure Local) enables a group of independent servers to work together to improve availability and scalability for clustered roles (formerly known as clustered applications and services). These nodes are interconnected via hardware and software, and if one node fails, another assumes its roles through an automated failover process. Clustered roles are actively monitored and, if they stop functioning, are restarted or migrated to maintain service continuity. The feature also supports Cluster Shared Volumes (CSVs), which provide a unified, distributed namespace and consistent shared storage access across nodes, reducing service disruptions. Typical uses include high‑availability file shares, SQL Server instances, and Hyper‑V virtual machines. Failover Clustering is supported on Windows Server 2016, 2019, 2022, and 2025, and in Azure Local environments. -

HPE Serviceguard
Hewlett Packard Enterprise
HPE Serviceguard for Linux (SGLX) is a high‑availability (HA) and disaster‑recovery (DR) clustering solution designed to maximize uptime for critical Linux workloads, on‑premises, in virtualized environments, or across hybrid and public clouds. It continuously monitors applications, services, databases, servers, networks, storage, and processes; upon detecting faults, it performs fast, automated failover, often within four seconds, without compromising data integrity. SGLX supports both shared‑storage and shared‑nothing architectures (via its Flex Storage add‑on), enabling highly available SAP HANA, NFS, or other services even where SAN isn’t available. The HA‑only E5 edition delivers zero‑RPO application failover with robust monitoring and a workload‑centric GUI, while the HA + DR E7 edition adds multi‑target replication, automated and push‑button site recovery, DR rehearsal, and workload mobility across on‑premises and cloud.Starting Price: $30 per month -

SIOS DataKeeper
SIOS Technology Corp.
SIOS DataKeeper is a host‑based, block‑level replication solution that delivers real‑time, synchronous or asynchronous redundancy for Windows Server environments, integrating seamlessly with Windows Server Failover Clustering (WSFC). It enables "SANless" clusters—eliminating dependency on shared‑storage arrays—by replicating data across local, virtual, or cloud servers, including VMware, Hyper‑V, AWS, Azure, and Google Cloud Platform, while offering optimized performance without requiring hardware accelerators or compression devices. Once installed, it provides a new SIOS DataKeeper Volume resource in WSFC, supporting geographically dispersed clusters via cross‑subnet failover and configurable heartbeat parameters. Built-in WAN optimization and efficient compression maximize bandwidth use over local and wide‑area networks. -
