Virtuozzo main benefits in comparison to OpenVZ
- Ability to create Virtual Machines.
- In addition to Containers, one can create full-scale VMs using a build-in hypervisor. Both Containers and Virtual Machines are managed by the same tools in a uniform way.
- Virtuozzo Storage.
- A resilient and robust way to unify all your local nodes storage into a single highly available SAN-grade distributed storage system.
- Higher container density.
- Virtuozzo provides efficient memory and file sharing mechanisms (VZFS or pfcache) enabling higher container density and better performance of containers.
- Unified management tools for CTs and VMs
- Virtuozzo ships with number of management, monitoring, troubleshooting, and administration tools significantly reducing management, administration, and deployment costs. Specific tools include:
- Parallels Virtual Automation
- Number of additional CLI tools.
- Support and maintenance.
- Virtuozzo is a commercial product supported and maintained by Odin with options for 24×7 phone support and guarantees on maintenance schedules.
- Advanced recovery, monitoring, and back-up tools.
- Physical-to-Virtual (P2V) and Virtual-to-Physical (V2P) migration tools.
- Those tools allow easy conversion of existing physical machines into a container (and vice-versa) facilitating the adoption of virtualized infrastructure.
- Common client-server XML-based management API.
- API allows easily integration of Virtuozzo into existing management infrastructure and development of additional management and monitoring modules.
- Traffic accounting tools.
- These tools enable bandwidth management and control for individual containers and provide additional security mechanisms for containers running on the same host.
