Software licensing

Software licensing as a #1 barrier in commercial grid deployments

Traditionally, software licenses have been provided on the basis of a named user, node-locked host, number of concurrent jobs or possibly a floating site license. These models are not sufficiently flexible to support commercial applications that access resources beyond the current administrative domain – possibly as a Utility-like service outside the organization or Software as a Service (SaaS) model.

Software licensing is identified as a particular concern for enterprise IT managers as they start to deploy virtual Grids in any meaningful way. For all the potential benefits of Grids, IT departments cannot afford to buy software licenses for every device in the service oriented infrastructure that by nature consumes resources dynamically.

In addition, the Grid-based Service-Oriented Architecture (SOA) solutions together with other technologies trends such as multi-core and virtualization environment are forcing Independent Software Vendors (ISV) to move away from traditional software licensing models.
