3 An Introduction to Cloud Computing with OpenNebula
Infrastructure as a Service Types of Cloud Services
What Who On-demand access to any application
End-user (does not care about hw or sw)
Platform for building and delivering web
applications
Developer (no managing of the underlying hw &
swlayers)
Raw computer infrastructure
System Administrator (complete management of the
computer infrastructure)
Software as a Service
ᄎ
Platform as a Service
Infrastructure as a Service
Physical Infrastructure
4 An Introduction to Cloud Computing with OpenNebula
Infrastructure as a Service Types of Cloud Deployments
• Simple Web Interface
• Raw Infrastructure Resources
• Pay-as-you-go (On-demand access)
• Elastic & “infinite” Capacity
Public Cloud
5 An Introduction to Cloud Computing with OpenNebula
• Simple Web Interface
• Raw Infrastructure Resources
• Pay-as-you-go (On-demand access)
• Elastic & “infinite” Capacity
Public Cloud
A “Public Cloud behind the firewall”
• Simplify internal operations
• Dynamic allocation of resources
• Higher utilization & operational savings
• Security concerns
Private Cloud

8 An Introduction to Cloud Computing with OpenNebula
Infrastructure as a Service Challenges of IaaS Clouds
● How do I provision a new VM? Image Management & Context
● Where do I store the disks? Storage
● How do I set up networking for a multitier service? Network & VLANs
● Where do I put my web server VM? Monitoring & Scheduling
● How do I manage any hypervisor? Virtualization
● Who has access to the Cloud’s resources? User & Role Management
● How do I manage my distributed infrastructure? Interfaces & APIs

11 An Introduction to Cloud Computing with OpenNebula
The OpenNebula Model
● Adaptable: Integration capabilities to fit into any data center
● Enterprise-ready: Upgrade process and commercial support
● No Lock-in: Broad infrastructure and platform independent
● Light: Efficient & simple
● Proven: Rigorously tested, mature and widely used
● Powerful: Advanced features for virtualized
● Scalable: single instance & multi-tier architectures
● Be interoperable! rich set of API's & Interfaces
● Open Source: Apache License v2
An Enterprise-ready Open-source Platform to Manage Cloud Data Centers

16 An Introduction to Cloud Computing with OpenNebula
The Anatomy of the Cloud Cloud Architecture - The Internals of the Cloud
Interfaces, Tools & API • CLI & Sunstone (GUI) • API • Cloud (EC2,OCCI) • Service Management & Catalogs
Compute Hosts • Grouped into logical clusters • Multiple hypervisors • Monitoring
Storage • VM disks (file & block) • Image Distribution • Multiple Backends
Multi-tenancy • AAA Services • Scheduling • Permissions & roles
Network • VLAN • Firewalling • Multiple Technologies
17 An Introduction to Cloud Computing with OpenNebula
The Anatomy of the Cloud Basic OpenNebula Deployment
• Repository of VM images • Multiple Backends (LVM, Ceph)
Monitoring,Virtualization, Storage and Network
• Provides physical resources for the VMs • Must have a hypervisor installed
