Portable, Interoperable Cloud Applications using TOSCA

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

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 each component’s properties can

also be inspected as published within the TOSCA service template

Downloading / Exporting the “SugarCRM” Application’s CSAR

… another company wants to use “SugarCRM” in their cloud and decides to download the CSAR from the marketplace for their developers to work with.

… developers can choose to edit the components’ properties or simply use the defaults settings packaged in the CSAR file prior to deployment

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
