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

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
