This integration allows for hybrid cloud scenarios where workloads can be seamlessly moved between on-premises environments and Azure, providing flexibility and scalability.
Security and isolation
Robust security features help protect virtual machines and their data, ensuring that workloads run in isolated environments:
Shielded Virtual Machines provide comprehensive protection for sensitive workloads through BitLocker encryption, Secure Boot verification, and TPM 2.0 attestation. Host Guardian Service (HGS) ensures only authorized hosts can run shielded VMs, protecting against compromised administrators and malicious insiders.
Generation 2 virtual machines deliver enhanced security with UEFI firmware, Secure Boot capabilities, and improved malware resistance. Virtual TPM 2.0 support enables BitLocker encryption within guest operating systems and supports Windows Hello for Business authentication.
Network isolation through Virtual LANs (VLANs), private virtual switches, and software-defined networking (SDN) creates secure network segments that prevent unauthorized lateral movement between workloads.
Storage flexibility
Flexible storage options meet diverse organizational requirements, from local disks to cost-effective hyperconverged solutions to existing SAN deployments:
Storage Spaces Direct creates hyperconverged infrastructure by pooling local storage across cluster nodes into a single, highly available storage namespace. This software-defined storage solution eliminates traditional SAN requirements while delivering enterprise-class features including fault tolerance, automatic repair, and performance optimization. Organizations achieve lower storage costs compared to traditional SAN solutions while gaining simplified management and improved performance through NVMe and persistent memory support.
Storage Spaces enables disaggregated storage architectures by pooling Just a Bunch of Disks (JBOD) enclosures into resilient storage pools with configurable redundancy levels. This approach provides flexibility to scale storage independently from compute resources while maintaining high availability through mirror, parity, or dual-parity configurations.
Local storage options support various deployment scenarios from development environments using single drives to production workloads with NVMe arrays. Direct-attached storage provides optimal performance for I/O-intensive applications while reducing complexity for smaller deployments or edge computing scenarios.
SAN connectivity supports both iSCSI and Fibre Channel protocols for integration with existing enterprise storage infrastructure. Multipath I/O (MPIO) ensures high availability and load balancing across multiple storage paths, while support for SMB 3.0 and NFS enables file-based storage scenarios with features like transparent failover and scale-out file server clustering.
High availability and business continuity
Comprehensive high availability and business continuity features help ensure mission-critical workloads remain operational:
Failover Clustering with Cluster Shared Volumes (CSV) enables automatic failover of virtual machines between cluster nodes, providing valuable uptime for mission-critical applications. Live migration enables planned maintenance without service interruption. CSV Cache improves performance by caching frequently accessed data in memory, while CSV Block Cache uses system memory on storage-rich nodes to accelerate read operations.
Hyper-V Replica delivers cost-effective disaster recovery by asynchronously replicating virtual machines to secondary sites over standard network connections, eliminating expensive SAN replication requirements. Recovery Point Objectives (RPO) can be as low as 30 seconds to ensure minimal data loss.
Shared nothing live migration enables virtual machines to be moved between hosts without shared storage, enabling flexible resource allocation and load balancing across the cluster. This feature supports scenarios where hosts have different storage configurations or when migrating workloads between geographically distributed sites.
Storage Migration enables moving virtual machine storage between different storage arrays without downtime, facilitating storage upgrades and load balancing across the infrastructure.
