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
3
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
4
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”
5
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
6
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
7
SugarCRM Topology / Properties
The “Topology” of the application and each component’s properties can also be inspected as published within the TOSCA service template
8
Downloading / Exporting the “SugarCRM” Application’s CSAR
9
… another company wants to use “SugarCRM” in their cloud and decides to download the CSAR from the marketplace for their developers to work with.
“SugarCRM” Imported into IBM Workload Deployer (IWD)
10
… using the Cloud Service Archive (CSAR) for the “SugarCRM” app,
which was downloaded from the IBM Cloud Marketplace
Demonstrating Seamless TOSCA “Tool” Portability
The “SugarCRM” Application’s Topology Template Viewed in IWD
11
… developers can choose to edit the components’ properties or simply use the defaults settings packaged in the CSAR file prior to deployment
Web Server Tier (left), Database Tier (right)
The “SugarCRM” TOSCA Application is Fully Deployed and Running using IBM SmartCloud Foundation Services
12
… we can see that both the Web Server and Database Tiers are running
and assigned Public IP Addresses
Login to “SugarCRM” application running on an IBM Cloud
13
… using the IP Address allocated by IBM’s Cloud for the Apache Web Server which was part of the Web Server Tier of the TOSCA “SugarCRM” application
Demonstrating Seamless TOSCA “Run-time” Portability
