Software as a Service

SaaS demonstration series

Developing new SaaS applications or transforming existing packaged solutions to a SaaS model can be challenging. Our demonstration series contain common scenarios in sample applications, technologies, techniques, and best practices for delivering your software as a hosted service.

These sample demonstrations from developerWorks show you the benefits of using IBM technology from the DB2, Lotus, Rational, Tivoli, and WebSphere product families to deliver secure and customizable multi-tenant applications.

The demonstration series provides examples of common industry scenarios, architecture guidance, and tips on how to use a robust suite of IBM middleware to overcome development challenges and deliver SaaS applications.

This series includes examples of how to support multi-tenancy using IBM middleware when composing user interfaces and designing data architectures for SaaS applications.
