1. TOSCA Topology and Orchestration Specification for Cloud Applications International Cloud Symposium October 10-12, 2012 Paul Lipton, VP Industry Standards, CA Technologies OASIS TOSCA Technical Committee Co-Chair paul.lipton@ca.com

2. Background —TOSCA Technical Committee formed in December 2011 −Initial technical contribution: CA Technologies, CapGemini, Cisco, Citrix, EMC, IBM, NetApp, PwC, Red Hat, SAP, Software AG, Virtunomic, WSO2 —Grown to be one of the largest TCs (> 100 members)

3. Members (Also Many Observers)

4. Services Portability is Not Easy! —Portability (install, operate, regulate, market/exchange) —Many challenges with real-world services −Complex software and hardware infratructure Complicated requirements, Sequence-of-operation, relationships, groupings, capacity, dependency, configuration, and much, much more! Approach 1: Moving virtual images? −Uncoordinated, unsynchronized snapshots of virtual components Operation at the component level only No “understanding” of the overall service

5. Services Portability is Not Easy! —Portability (install, operate, regulate, market/exchange) —Many challenges with real-world services −Complex software and hardware infratructure Complicated requirements, Sequence-of-operation, relationships, groupings, capacity, dependency, configuration, and much, much more! Approach 2: “Bundle” the service components in a “package” for a service provider? Not adequate! −Another provider might not have a clue how install, operate, regulate, manage the service Detailed skills and information needed!

6. TOSCA Addresses Service Portability —TOSCA Use Cases Across Service Lifecycle −Deploy Cloud Services: Install, Remove, Configure, Integrate −Operate Cloud Services: Start, Stop, Patch, Scale −Regulation of Cloud Services: Disaster Recovery, Geo- Redundancy, Optimization (cost, volume, etc.), Verification −Markets and Exchanges for Cloud Services

7. Introducing TOSCA —Standardized description language −Structure and nature of an IT Service (its topology model) −Behavior and “best practices” (plans such as build, deploy, patch, shutdown, etc.) −Packaging format —Simple declarative model that spans applications, virtual and physical infrastructure Topology and Orchestration Specification for Cloud Applications

8. More Colorfully… 8 Topology Model Orchestrated Behaviours (Plans) Relationship Node Operation Task TOSCA Service Templates – a model based approach!

9. 9 How Plans and Nodes Fit Together —Task of a plan refers to interface of a topology node —Topology node specifies all interfaces offered to manage it —Interface is bound to a concrete implementation —Implementation already available at providers side, or —Implementation is copied from somewhere, or —A standardized Cloud Interface (Iaas, PaaS, SaaS) is used, or... Apache Webserver … Deploy Web Farm … … Script - - - - - - - …refers to… …bound to…

10. Vision: A Complete TOSCA Eco-System 10 Service Catalog 1. Model Once 2. Publish 3. Browse and Select 4. Tools to optimize, report, etc. 6. Use Service Template Service Instance 5. Deploy anywhere

11. TOSCA Status —Goal: submit v1 of the language for public review by the end of 2012 −Additional language definitions and refinements will be standardized in late 2013, as the industry and use cases continue to mature −Interoperability testing subcommittee started in September 2012 11

12. Summary —Model-driven, portability across the service lifecycle −Examples: scale-in, scale-out, patch, multi-cloud, regulate, burst, markets −Enabled by service-centric topology models acted upon by TOSCA plans —Can work with other standards, e.g., OVF, CIMI, OCCI, BPMN, etc. Working with TM Forum. —Immense TOSCA eco-system potential −Multi-cloud services to meet requirements, restrictions, regulations −Automation with faster deploy, test, update, existing app migration, etc. −Simulation (like debugging) of deployment and changes −Cloud service marketplaces 12
