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


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






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







Public Cloud






Private Cloud

• Suplement the capacity of the Private Cloud

• Utility Computing dream made a reality!

Hybrid Cloud



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

An Uniform Management Layer

Infrastructure as a Service


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

The Anatomy of the Cloud Different Perspectives of the Cloud – Demands from the Different Communities

Cloud Consumer

Cloud Administrator

Cloud Integrator

Cloud Application Developer


The Anatomy of the Cloud OpenNebula Architecture - Infrastructure Agnostic and Highly Customizable

OpenNebula core

Virtualization Images

Storage Network

Auth

Monitoring

Scheduler

XML-RPC API

OCA (Ruby, Java)

CLI GUI Cloud Servers

DB

Languages


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


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
