What is Apache CloudStack?

Apache CloudStack is a scalable, multi-tenant, open source, purpose-built, cloud orchestration platform for delivering turnkey Infrastructure-as-a-Service clouds. the most mature, most scalable, most proven IaaS platform available today.

Characteristics of CloudsOn-Demand Self-Service

Broad Network Access

Resource Pooling

Rapid Elasticity

Measured Service

API Access

CLOUD VIRTUALIZATION

Cloud 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

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: VMware CloudFoundry, Google AppEngine, Windows Azure, Rackspace Sites, Red Hat OpenShift, Active State Stackato, Appfog

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, OpenNebula

What CloudStack Provides

Feature HighlightsEasy InstallationSimple to configure and use in minutes.Broad Hypervisor support(KVM, XenServer, Xen Cloud Platform, VMware via vCenter, Bare Metal via IPMI)Easy plugin modelAWS API fidelityScalability, High Availability, Load BalancingBroad vendor hardware for networking, storage supportChoice of interfaces Web UI, command line, REST-based APIDeveloper friendly, easy to get started, add, refactor, contribute..(We will see in demo..)

Its the heart of the CloudStack system. Manages the assignment of guest VMs to particular hosts. Uses algorithms like First fit, Disperse, Fill first etc, supports overprovisioning.Manages the assignment of public and private IP addresses to particular accountsManages the allocation of storage to guests as virtual disks.Manages snapshots, templates, and ISO images, possibly replicating them across data centersThe Management Server

Domain is a unit of isolation that represents a customer org, business unit or a resellerDomain can have arbitrary levels of sub- domainsA Domain can have one or more accountsAn Account represents one or more users and is the basic unit of isolationAdmin can limit resources at the Account or Domain
