Cloud architecture refactoring & private cloud transformation

A legacy estate on rented VMs — costly and fragile

The organization ran a legacy enterprise infrastructure on rented virtual machines in a third-party data center. The architecture had grown over time with no long-term modernization strategy, leaving high operating costs, limited scalability, and weak disaster recovery.

Key challenges:

• High monthly infrastructure costs
• Dependence on third-party VM hosting
• Limited scalability
• Backups limited to once per week
• Increased recovery risk
• Aging infrastructure architecture
• No cloud optimization strategy

The objective: redesign the architecture, improve resilience, and significantly cut operating costs — without impacting business continuity.

A phased move to a modern private cloud

A comprehensive cloud transformation strategy was developed and executed to migrate the environment from rented virtual machines to a modern private cloud platform.

The initiative included:

• Infrastructure assessment and capacity planning
• Private cloud architecture design
• Virtualization platform consolidation
• Workload migration planning
• Backup and disaster recovery redesign
• Infrastructure optimization
• Performance tuning
• Cost optimization analysis

The migration was performed in phases to minimize operational risk and keep business operations uninterrupted.

Lower cost, daily backups, stronger resilience

• Migrated business-critical workloads with no data loss
• Improved backup frequency from weekly to daily
• Increased infrastructure resilience and recoverability
• Improved scalability for future growth
• Reduced dependence on external hosting providers
• Established a modern private cloud architecture
• Enhanced operational visibility and infrastructure management

What was put in place

Infrastructure:

• Private cloud platform
• Enterprise virtualization cluster
• High-availability configuration
• Centralized storage

Backup & recovery:

• Daily backups
• Tiered retention policies
• Disaster recovery procedures
• Automated backup validation
