Enterprise Virtualization & Private Clouds

Design, deployment, scaling, and 24/7 maintenance of enterprise-grade virtualization infrastructure. We build resilient foundations for mission-critical business workloads, optimize compute resource utilization, and eliminate vendor lock-in risks.

Key Capabilities

1. High-Availability VMware vSphere Clusters

  • Continuous Availability (HA & Fault Tolerance): zero Single Point of Failure (No SPOF) architecture. Automatic virtual machine failover on host crashes and continuous protection for mission-critical enterprise services.
  • Dynamic Resource Optimization (DRS & Storage DRS): automated load balancing of CPU, RAM, and storage I/O across cluster nodes under changing workload patterns.
  • Hyperconverged Infrastructure with VMware vSAN: high-performance software-defined storage pools (All-Flash, Hybrid, and multi-datacenter Stretched Clusters) delivering maximum IOPS and predictable low latency.
  • Multi-Tenant Private Clouds with Cloud Director: self-service vApp catalogs, strict role-based access control (RBAC), and isolated software-defined networks (NSX).

2. Migration to Open-Source & Alternative Hypervisors

  • Seamless Transition from VMware and Hyper-V:
    • Proxmox VE: battle-tested open-source enterprise virtualization platform based on KVM and Debian, featuring native Ceph storage clustering and Corosync consensus.
    • RED Virtualization: enterprise certified virtualization platform for sovereign server and VDI environments.
    • zVirt: industrial KVM-based enterprise virtualization with centralized web management and enterprise SAN/NAS integrations.
    • Brest Virtualization Suite: secure cloud virtualization environment powered by Astra Linux Special Edition.
  • VM Conversion (V2V / P2V): phased migration of disks and virtual machine configurations with near-zero downtime windows (minimal RTO/RPO) and strict data consistency checks.
  • Hybrid Coexistence: seamless interoperation of existing VMware infrastructure alongside the new hypervisor cluster during staged transitions.

3. Fault-Tolerant Storage & Network Interconnects

  • Network Fabric: fault-tolerant distributed switches (vSphere Distributed Switch / Open vSwitch), link aggregation (LACP), traffic isolation (VLAN / VXLAN), and redundant 10/25/100 GbE fabric interconnects.
  • Storage Integration: enterprise external storage arrays over iSCSI, Fibre Channel, NFS, and NVMe-oF with multi-pathing (MPIO) optimization.
  • Software-Defined Storage (Ceph & ZFS): scalable, self-healing distributed storage clusters tailored for Proxmox VE and KVM-based deployments.

4. Enterprise Backup & Disaster Recovery (DR)

  • Full integration with leading backup platforms: Veeam Backup & Replication, Proxmox Backup Server (PBS) with client-side deduplication, and Cyber Backup (Acronis).
  • Automated Disaster Recovery (DR) runbooks and regular non-disruptive failover drills.

Technology Stack

  • Hypervisors & Management: VMware vSphere (ESXi 7/8), vCenter Server, VMware Cloud Director, Proxmox VE, RED Virtualization, zVirt, Brest, KVM / oVirt.
  • Software-Defined Storage: VMware vSAN, Ceph Storage, ZFS, TrueNAS Enterprise.
  • Networking: VMware Distributed Switch (vDS), Open vSwitch (OVS), Linux Bridges, VLAN, VXLAN.
  • Backup & DR: Veeam Backup & Replication, Proxmox Backup Server, Cyber Backup.
  • Automation & IaC: Ansible, Terraform (vSphere & Proxmox Providers), VMware PowerCLI, Packer.

Implementation Workflow

  1. Audit & Capacity Sizing: comprehensive inventory of existing VMs, measuring real resource consumption (CPU, RAM, storage IOPS, network bandwidth).
  2. Target Architecture Blueprint: designing high-availability compute, network, and storage topologies with zero single points of failure.
  3. Pilot Cluster & Chaos Testing: deploying a sandbox cluster, validating HA failover mechanisms, and simulating disaster events (link loss, node crash, disk failure).
  4. Staged Migration: planning maintenance windows, running test migrations, delta data synchronization, and clean production cutover.
  5. Documentation & Handover: operational runbooks, as-built documentation, network topology diagrams, and team knowledge transfer.
  6. 24/7 Operations & Support: continuous cluster telemetry, capacity planning, and SLA-backed incident response.
