  • 2. Contents● What is OpenNebula?● Design Principles & Vision● The Anatomy of an IaaS Cloud● Building an IaaS Cloud: A single node example● Lessons Learned
  • 3. What is OpenNebula? Public Cloud Private Cloud Simple Web Interface A Cloud behind a firewall Infrastructure Resources Security Concerns Elastic & “infinite” Improve Operations Hybrid Cloud / CloudBursting Supplement Capacity of the Private Utility Computing for Real
  • 4. What is OpenNebula? Image ManagementMonitoring & Scheduling Networking Multi-tenancy Interfaces & APIs VM VM VM VM VM VM VM VM Hypervisor Physical Hardware .. Hypervisor Physical Hardware Host Host
  • 5. Design Principles and Vision● Flexible: One solution can not fit all data-centers● Simple: just-what-you-need components & simple protocols● Scalable: single instance & multi-tier architectures● Open Source: Apache License v2.0● Provide basic components, but easily hack by others
  • 6. The Anatomy of an IaaS Cloud Interfaces, Tools & API ● CLI & Sunstone (GUI) ● API ● Cloud (EC2,OCCI) ● Service Management & CatalogsNetwork Storage● VLAN ● VM disks (file & block)● Firewalling ● Image Distribution● Multiple Technologies ● Multiple Backends Multi-tenancy ● AAA Services ● Scheduling ● Permissions & roles Compute Hosts ● Grouped in logical clusters ● Multiple hypervisors ● Monitoring
  • 7. Building an IaaS Cloud: A single node example Image Datastore System Datastore (DS_ID: 1) (DS_ID: 0) "NAS" "NAS" wlan0 Internet vbr0 VM VM KVM My Laptop
  • 8. Building an IaaS Cloud: Tools & InterfacesTools ● DevOps vs Users ● Command Line Interface Command Line Interface ● GUI ○ Sunstone ○ Self-service ● Cloud APIs ○ EC2 Query API ○ OCCI
  • 9. Building an IaaS Cloud: HostsHost Management ● Monitoring ○ Simple - SSH probes ○ Ganglia HOST HOST HOST ● Cluster ○ Logical set of: ■ Storage ■ Network ■ Hosts ○ Deal with heterogeneity
  • 10. Building an IaaS Cloud: StorageStorage ● Datastore ○ Image store Image Datastore System Datastore (DS_ID: 1) (DS_ID: 0) ○ Balance I/O ○ Policies ○ File, iSCSI, LVM, VMFS "NAS" "NAS" ● Image distribution ○ System Datastore ○ Shared/Distributed FS ○ SSH ○ iSCSI ○ LVM
  • 11. Building an IaaS Cloud: Network Images ● Files vs Block devices ○ Performance Image Datastore System Datastore (DS_ID: 1) (DS_ID: 0) ○ Management ● Types ○ Golden Images "NAS" "NAS" ○ Persistent ○ Volatile ● Context CD-ROM with custom data Disk images
  • 12. Building an IaaS Cloud: Network Networks ● Define a MAC-IP address space ● Layer 2 Isolation (drivers) ○ 802.1Q (Tagging) ○ OpenvSwitch vbr0 ○ ebtables VM VM VR ○ Flat ● Layer 3 simple firewalling ○ TCP/UDP ports Internet ○ ICMPs ● Virtual Router
  • 13. Building an IaaS Cloud: Virtualization Virtualization ● Virtual Machine Templates ○ Capacity ○ Disks VM VM ○ NICs Hypervisor ○ Other (VNC, OS,...) ● Support VM operations ○ Stop/Resume ○ Migration (live) ○ Attach/Detach ○ Shutdown/Reboot/Reset ● Hypervisor ○ Agnostic ○ Xen, KVM and VMware
  • 14. Building an IaaS Cloud: Misc Services AuthZ, AuthN & Acct. ● Multi-tenancy ○ Groups ○ Permissions & ACLs ● Authentication ○ X509 Core & Scheduler ○ SSH Keys ● OpenNebula core ○ LDAP daemon ○ Internal ○ Orchestration ● Authorization ○ Driver based ○ Quotas ○ Fast & Robust (C++) ● Accounting (Billing) ● Scheduler ○ Matchmaking
  • 15. Building an IaaS Cloud: Misc ServicesMarketplace Marketplace ● Ready-to-use Image Sharing ● Store meta-data ● Images stored elsewhere ● Meeting point Devs & Users ● "one-click" deployment
  • 16. Building an IaaS Cloud: Integration at a Glance
  • 17. Building an IaaS Cloud: Integration at a Glance
  • 18. History of the Project Third party scalability ● Develop & innovate tests: 16000 VMs ● Support the community ● Collaborate Commercial Support TP v3.2 3.4 3.8 v1.0 v1.2 v1.4 v2.0 v2.2 v3.02005 2008 2009 2010 2011 2012dsa group doing research… 4,000 downloads/month European Funding
  • 19. Lessons Learned Do not hide the Complexity, Architect the Cloud! ● Let IT staff adapt/desgin/develop their cloud deployments ● Design to Automate ● Scale your deployments Be Interoperable, Have a Rich set of API’s & Interfaces ● Be prepared for different uses cases (don’t look at the service) ● Be prepared to deal with different solutions (storage, virt., nets) ● Be prepared to interoperate at different levels
