Iona Technologies Inc. today announced its own hybrid model for selling Artix, its closed source enterprise services bus (ESB), and FUSE, its open source ESB based on technology developed by the Apache Foundation. The hybrid model, which will allow customers to deploy a combination of Artix and FUSE in their service-oriented architecture (SOA) environment, is based on customer demand, said Eric Newcomer, CTO at Iona.

Two analysts briefed prior to the announcement of the Iona ESB hybrid approach agree that it reflects a marketplace where enterprises may be mixing and matching open source and closed source products in their SOA implementations.

Dana Gardner, principal analyst at Interarbor Solutions LLC., said Iona's hybrid model reflects a new era where SOA architects and developers may not rely on just one ESB, whether it be open or closed source.
