5. The Cloud Provider Perspective
What are the Main Components to Build a Cloud Infrastructure?!
VM Instance Networks
Internet
• Public and private networks
Front-end Hosts
• Authentication • Multiple hypervisors
• Authorization • Up to 500 hosts
• ACLs, roles, • Automatic failover and HA
groups… • Resource pools
• Accounting • Automatic resource allocation
• Logging
• Resource quotas
Service Networks Datastores
• Monitoring, control… • VM image storage
• Live migration… • Multiple datastores
• Storage access… • Heterogeneous configurations
• Shared or non-shared

7. The Cloud Provider Perspective
Clustering the Physical Resources!
Clusters
• Pools of hosts that share datastores and networks
• Used for load balancing, high availability, and high performance computing
Multiple Datastores per Cluster
• Balance I/O operations between storage servers
• Define different SLA policies (e.g. backup) and performance features for
different VM types or users
The OpenNebula Project 7/25

8. The Cloud Provider Perspective
Centralized Management of Multiple OpenNebula Instances (Zones)!
Federation of Clouds
• Multi-tier architecture
• Scalability
oZones Server • Isolation
• Portal • Multiple-site support
Cloud • Cloud API (EC2, OCCI)
Administrator/ • Global AuthN
Consumer

9. The Cloud Provider Perspective
On-demand Provision of Virtual Data Centers!
Virtual Private Cloud Computing
● Typical scenario in large organizations
and cloud providers
● On-demand provision of fully-
configurable and isolated VDC with full
control and capacity to administer its
users and resources
