ClusterControl is a hybrid, multi-cloud database ops orchestration platform for MongoDB, Elasticsearch, Redis, TimescaleDB, SQL Server on Linux, Galera Cluster, PostgreSQL, and MySQL in on-premises, cloud, and hybrid environments. It handles full-lifecycle operations, from deployment to failover, backup and more. With its full suite of databases, ops features and ability to be deployed in any environment, it enables organizations to implement the Sovereign DBaaS concept. ClusterControl is perfect for organizations that need to reliably run large-scale, open-source database operations but don't want to be limited by traditional DBaaS providers in environment choice, open-source license stability, and DB access.

Arctera InfoScale is an advanced solution designed to provide real-time resilience and high availability for applications, data services, and infrastructure. It helps businesses reduce downtime by up to 98% with its ability to quickly recover from disruptions, ensuring that critical systems remain operational. By leveraging immutable checkpoints and advanced disaster recovery capabilities, InfoScale ensures business continuity even during cyberattacks or unplanned outages. The platform supports hybrid cloud environments, allowing businesses to seamlessly orchestrate workloads across on-premises, cloud, and containerized systems.

Oracle Real Application Clusters (RAC) is a unique, scale-everything, highly available database architecture that transparently scales both reads and writes for all workloads, including OLTP, analytics, AI vectors, SaaS, JSON, batch, text, graph, IoT, and in-memory. It effortlessly scales complex applications such as SAP, Oracle Fusion Applications, and Salesforce workloads. Oracle RAC delivers the lowest latency and highest throughput for all data needs through its unique fused cache across servers, ensuring ultrafast local data access. Parallelized workloads across all CPUs guarantee maximum throughput, and the integration of Oracle’s storage design enables seamless online storage expansion. Unlike other databases that depend on public cloud infrastructures, sharding, or read replicas for scalability, Oracle RAC guarantees the lowest latency and highest throughput out of the box.

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.

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.

SIOS LifeKeeper for Windows is a comprehensive high-availability and disaster‑recovery solution that integrates failover clustering, continuous application monitoring, data replication, and flexible recovery policies to deliver 99.99 % uptime for Microsoft Windows Server environments—whether physical, virtual, cloud, hybrid‑cloud, or multicloud. Administrators can build SAN‑based or SANless clusters using a variety of storage types (direct‑attached SCSI, iSCSI, Fibre Channel, or local disk) and choose between local or remote standby servers that support both high availability and disaster recovery. LifeKeeper offers real‑time block‑level replication via bundled DataKeeper, with WAN‑optimized performance that includes nine levels of compression, bandwidth throttling, and integrated WAN acceleration, ensuring efficient replication across cloud regions or over WAN without hardware accelerators.
