Hewlett-Packard Co says its customers are choosing to develop applications on Windows NT and deploy them against both Unix and Windows NT servers in internet environments. That’s why its four- tier Domain Foundation development and deployment technologies – web client and web server, application server and database server – are skewed to NT at the front-end and Unix with NT interoperability at the back-end. HP is bundling the run-time version of Iona Technologies Ltd’s Orbix object request broker and Netscape Communication Corp’s LDAP directory services with HP-UX as FoundationWare. Foundation Tools include its OpenStudio Visual C++ implementation, programming wizards, plus Java Workshop and an SDK for creating FoundationWare services. Additional transaction processing, security and management services from third parties plus in-house middleware will be added to FoundationWare at the beginning of May. HP says it will continue to sell and support its SoftBench Unix development environment but customers of its ORB-Plus request broker are being migrated to Orbix.
