Cloud Hosting for 1C:Enterprise on Proxmox

Client

A mid-tier hosting provider offering infrastructure-as-a-service to business customers

Challenge

The client needed a reliable, self-hosted virtualization platform to deliver ready-to-use cloud 1C:Enterprise instances as a managed product. The stack required: Proxmox VE cluster for virtualization, Windows Server VMs running 1C:Enterprise server + PostgreSQL + Apache, a RouterOS (MikroTik) VM as the edge router with HAProxy for load balancing, network connectivity between nodes, storage replication, and automated backups β€” all maintained as a commercial service for dozens of end customers.

Solution

1. Proxmox VE Cluster
  • Deployed and configured Proxmox VE cluster across multiple physical servers
  • Shared storage and live migration for high availability
  • Resource isolation and quotas per customer VM
  • Regular cluster maintenance, updates, and capacity planning
2. Network & Routing
  • RouterOS (MikroTik) VM as the edge router and firewall
  • HAProxy for load balancing and reverse proxying to backend VMs
  • VLAN segmentation for customer isolation
  • VPN access for secure administrative connections
3. Windows Server VM Templates
  • Golden image template: Windows Server + 1C:Enterprise + PostgreSQL + Apache
  • Automated VM provisioning from template for new customers
  • Scheduled Windows Updates and security hardening
  • Per-customer resource allocation (CPU, RAM, disk)
4. Replication & High Availability
  • Storage-level replication between Proxmox nodes
  • VM live migration for maintenance without downtime
  • Failover configuration for critical customer workloads
5. Backups & Disaster Recovery
  • Automated daily VM backups with retention policy
  • Off-site backup replication
  • Documented restore procedures, periodically tested
  • Backup monitoring and alerting on failures
6. Monitoring & Support
  • Infrastructure monitoring (host health, VM status, storage, network)
  • Proactive alerting on resource exhaustion and service degradation
  • Tiered support for end customers: incident handling, performance tuning, scaling
