2 An Introduction to Cloud Computing with OpenNebula

Agenda

An Introduction to Cloud Computing with OpenNebula

● Infrastructure as a Service

● The OpenNebula Model

● The Anatomy of the Cloud


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



Types of Cloud Deployments

•Simple Web Interface

• Raw Infrastructure Resources

• Pay-as-you-go (On-demand access)

• Elastic &“infinite” Capacity

Public Cloud


• Simple Web Interface




Public Cloud

A “Public Cloud behind the firewall”

• Simplify internal operations

• Dynamic allocation of resources

• Higher utilization & operational savings

• Security concerns

Private Cloud








Public Cloud






Private Cloud

• Supplement the capacity of the Private Cloud

• Utility Computing dream made a reality!

Hybrid Cloud

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

Challenges of IaaS Clouds


An Uniform Management Layer



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


Widely Used to Build Enterprise Private Clouds in Medium and Large Data Centers
