This document discusses the OpenNebula model for cloud provisioning and its multi-tenant infrastructure. OpenNebula allows sharing of physical resources across multiple users and virtualizes them. It supports self-provisioning of virtual resources and accommodates different provisioning models. OpenNebula also allows grouping resources into logical clusters that can be assigned to different user groups with quotas and policies to control usage.

- 1. Welcome to OpenNebulaConf 2014! Understanding the OpenNebula Model for Cloud Provisioning Ruben S. Montero
- 2. A Multi-tenant Infrastructure Physical Resource ● Tools to establish sharing policies of physical resources ● Proper isolation of users ● Control and limit usage Virtual Resources ● Self-provisioning ● Accomodate different user provisioning models (cattle vs pet) #OpenNebulaConf OpenNebula.org
- 3. A Multi-tenant Infrastructure Logical group of hypervisors, datastores and virtual networks Cluster A Cluster B Placement Policies: Allocate a VM to a given cluster Access Control: Allocate users to a given cluster Resources can be assigned to more than one cluster to better balance resource allocation 4.12 #OpenNebulaConf OpenNebula.org
- 4. A Multi-tenant Infrastructure A cluster provides resources to a user group Cluster A Cluster B User Group A User Group B Quota:Limit group/user usage Self-Provision: ● VMs ↔ Hypervisors ● Images ↔ Datastores ● Address↔Virtual Networks Showback, users get an estimated associated resource usage cost based on CPU and MEMORY cost 4.12 #OpenNebulaConf OpenNebula.org
- 5. A Multi-tenant Infrastructure Virtual Data Center Resource Provider User Group A VDC Admin: Autonomic management of VDC users Simple Provision: Use a cloud-like interface Federate: VDC can spread several Datacenters / Zones #OpenNebulaConf OpenNebula.org
- 6. Bootstraping the Cloud VDC admin can save VM changes for her VDC users 3. VM Template ● Include HW presets ● Hypervisor settings ● Placement policies ● Cost 1. Disks ● Vanilla OS installations ● Pre-built appliances ● Context & user inputs Security Groups with VNET semantics 4.12 2. Network Interface Controllers ● Pre-defined connections ● Set at deployment time ● Re-use Network attributes Datastore & Virtual Network determines running cluster #OpenNebulaConf OpenNebula.org
- 7. Interfacing the Cloud: Cattle vs Pets ● Easily disposed ● Simple interfaces ● Short life-cycles ● HA, Backup policies ● Richer interfaces ● Long-lasting life-cycles #OpenNebulaConf OpenNebula.org
- 8. Interfacing the Cloud: Cattles ● Instantiate many times same installation ● Use context ● Limited set of operations ● mainly GUI access - CloudView Cloud View Improve Clone VMs to templates to support multiple disks 4.12 Clone before deploy (instantiate to persistent) 4.12 Taking care of those cattles... #OpenNebulaConf OpenNebula.org
- 9. Interfacing the Cloud: Pets ● Instantiate many times same installation ● Persistency + Backup (snapshots) ● Rich set of operations ● API + CLI + Sunstone access Sunstone Cold attach of disks and NIC 4.12 Migrate VMs across system datastores 4.12 Taking care of those pets.. #OpenNebulaConf OpenNebula.org
