LignUp and rPath are leveraging Amazon's Elastic Computer Cloud (EC2) and Simple Storage Service (S3) to historically relieve developers of infrastructure worries and infrastructure costs as they try out new products and services.

Meanwhile, LignUp is sweetening the pot for developers who participate in the CodeLign developer program and use the LignUp Commmunications Applications Server by being able to use Amazon S3 and Amazon EC2 to help power their VoIP-enabled applications. They will also now each get a 600-minute Internet phone credit to build and test their VoIP-enabled Web services, application mashups, enterprise wikis, and portals.

LignUp is seeking to become the "WebLogic of voice," a reference to how the WebLogic application server helped define a category and encourage a land-grab by third-party ISVs in the mid-1990s.

LignUp's modular-architected, SIP-based "telephony middleware" platform is designed to help developers and ISVs and enterprises swiftly and agilely bring voice to their applications and services by engaging voice services as Web services, by picking from a library of WSDLs or "voicelets." Look for more event-driven and BPEL-friendly means to add voice and US functions to more business activities.
