OneFlow allows users and administrators to define, execute and manage multi-tiered applications, or services composed of interconnected Virtual Machines with deployment dependencies between them. Each group of Virtual Machines is deployed and managed as a single entity, and is completely integrated with the advanced OpenNebula user and group management.

Benefits:

• Define multi-tiered applications (services) as collection of applications
• Manage multi-tiered applications as a single entity
• Automatic execution of services with dependencies
• Provide configurable services from a catalog and self-service portal
• Enable tight, efficient administrative control
• Fine-grained access control for the secure sharing of services with other users
• Auto-scaling policies based on performance metrics and schedule

• Application Auto-scaling

OneGate allows Virtual Machine guests to push monitoring information to OpenNebula. Users and administrators can use it to gather metrics, detect problems in their applications, and trigger OneFlow auto-scaling rules
