- 2. Agenda • Overviewof CloudStack • Few numbers, Users, Introduction etc. • CloudStack Overview andArchitecture. • Demo of CloudStack • CloudStack Use Cases, Community and Getting Involved • Q&A
- 3. 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.
- 4. Characteristics of Clouds • On-Demand Self-Service • Broad Network Access • Resource Pooling • Rapid Elasticity • Measured Service • API Access CLOUD VIRTUALIZATION
- 5. 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
