Service Models

USER CLOUD a.k.a. SOFTWARE AS A SERVICE

Single application, multi-tenancy, network-based, one-to-many delivery of applications, all users have same access to features.

Examples: Salesforce.com, Google Docs, Red Hat Network/RHEL

DEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICE

Application developer model, Application deployed to an elastic service that autoscales, low administrative overhead. No concept of virtual machines or operating system. Code it and deploy it.

Examples: Google AppEngine, Windows Azure, Rackspace Site, Red Hat Makara, AWS RDS

SYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICE

Servers and storage are made available in a scalable way over a network.

Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack, Eucalyptus, Ubuntu Enterprise Cloud, OpenNebula, Vcloud

SaaS

PaaS

IaaS

•Secure, multi-tenant cloud orchestration platform– Turnkey platform for delivering

IaaS clouds– Hypervisor agnostic– Scalable, secure and open– Open source, open standards– Deploys on premise or as a hosted

solution

•Deliver cloud services faster and cheaper

What is CloudStack?

Build your cloud the way the world’s most successful clouds

are built

CloudStack Supports Multiple Cloud Strategies

Multi-tenantPublic Cloud

• Dedicated resources

• Security & total control

• Internal network• Managed by

Enterprise or 3rd party

• Mix of shared and dedicated resources

• Elastic scaling• Pay as you go• Public internet,

VPN access

Hosted Enterprise Cloud

Management Server

Single Management Server can manage multiple zones

Zones can be geographically distributed but low latency links are expected for better performance

Single MS node can manage up to 5K hosts.

Multiple MS nodes can be deployed as cluster for scale or redundancy

• Hosts– Servers onto which services will be provisioned

• Primary Storage– VM storage

• Cluster– A grouping of hosts and their associated storage

• Pod– Collection of clusters

• Network– Logical network associated with service offerings

• Secondary Storage– Template, snapshot and ISO storage

• Zone– Collection of pods, network offerings and secondary

storage

• Management Server Farm– Responsible for all management and provisioning tasks
