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

Broad Commodity and Enterprise Platform Support!

VM Instance Networks
Internet
•  VLAN per user (layer2)
•  Open vSwitch, 802.1q
•  Ebtables

Front-end Hosts
•  X509, LDAP, •  VMware,
ssh keys •  Xen
•  ACLs, •  KVM
permissions,
groups

Service Networks Datastores
•  SSH, Ganglia/Nagios •  DFS: NFS, Gluster, GlusterFS…
•  Additional monitor agents •  SAN: Fibre Channel, iSCSI, LVM…
•  SSH

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


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


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


Hybrid Cloud Computing!

● Extension of the local private infrastructure with resources from remote clouds
● Cloudbursting to meet peak or ﬂuctuating demands

Cloud Consumer

Cloud Provider

How Can I Operate my Cloud Infrastructure?!
… programming APIs (create new tools and integrate), web interfaces (simplify
operation), and command lined interface (create scripts)…

CLI

API
●  XML-RPC
●  OCA (Ruby, Java, Python)

Virtualization Drivers
Cloud
CLI GUI
Servers ●  Translate the OpenNebula VM life-
OCA (Ruby, Java) Scheduler cycle management into speciﬁc
hypervisor operations
XML-RPC API
Monitoring Drivers
●  Gather information about the
OpenNebula core
physical host and hypervisor status

Monitoring Storage Network
Hybrid Cloud Drivers
DB
Virtualization Images Auth ●  Interact with an external provider
instead of a hypervisor

Virtualization Driver Example:
Hypervisor: Xen
Action: migrate
Description: live-migrates a running VM to the speciﬁed Host
