Portable, Interoperable Cloud
Applications using TOSCA
Topology and Orchestration Specification for
Cloud Applications (TOSCA) Standard
Demonstrated using:
Vnomic’s Service Designer, IBM ISM Cloud Marketplace and
IBM Workload Deployer (IWD)
Business Value of TOSCA
Open Ecosystem for Cloud Services
• Vendor-independent definitions of complex Cloud services provide new marketing channel for solutions in the Cloud • Decoupling of Cloud infrastructure and Cloud content helps
focus on key aspects: Cloud Provider or Cloud Service Provider • Ability to deploy services in any standards-compliant
environment avoids vendor lock-in and eases migration
Interoperability and Composition
• Goes beyond VMs in describing the cloud application‘s components and their dependencies
• Composition of services defined independently by their domain experts into a higher-value service
• Key enabler for open hybrid Clouds
Easy Adoption of new Cloud Services
• Model-driven creation of Cloud Services
• Standardized deployment into various kinds of environments
– from test to production, from cloud A to cloud B • Process-driven Cloud Service Lifecycle
Management
Demo Messaging – TOSCA Enables…
Portability
– Specified package format: Cloud Service Archive (CSAR)
– Includes Topology of Application Components, Artifacts and their
Relationships / Dependencies
– Encapsulates “Expert Knowledge” of the service designer / architect
Interoperability
– Complete Tool and Runtime Interoperability
Lifecycle Management
– Each Component Exports its own Granular Lifecycle Management
Operations
Composing a TOSCA Service Template for a “SugarCRM” Application
using Vnomic’s Service Designer, www.vnomic.com
The SugarCRM application include 2 “Tiers”:
• Web Application Tier (Linux, Apache, PHP, SugarCRM) • Database Tier (Linux, MySQL)
Vnomic’s Service Designer tool supports
TOSCA“Deployment” directly to various Clouds
…including IBM’s SmartCloud Enterprise
for this demo, we choose to publish the “SugarCRM” Cloud Application
to IBM’s Integrated Service Mgmt. (ISM) Cloud Marketplace
which encapsulates the Application Architect’s “Expert Knowledge”

The Cloud Application is made “Portable” and packaged
using TOSCA’s Cloud Service Archive (CSAR) format
Showing SugarCRM” as a newly published service by Vnomic
into IBM’s “Cloud Marketplace”
Demonstrating the vision of an “Open Ecosystem” of cloud services
based upon TOSCA standardized service templates
TOSCA service templates could be published and shared on
both public and private marketplaces
SugarCRM Overview / Description of Service
Customers can use such marketplaces to get information on published
TOSCA cloud services to select those that best meet their needs
… as well as share fellow customer experiences, learn about
service licensing and support
SugarCRM Topology / Properties
The “Topology” of the application and its properties can also be
inspected as published within the TOSCA service template

… each component node’s properties can be edited or the defaults packaged in the
CSAR file can be used prior to deployment
SugarCRM TOSCA Application is SeFully Deployed and Running
