While standardising on its Solaris Unix, and, in-house, its Sparc RISC microprocessor family, Sun Microsystems Inc is determined to extend its reach into every aspect of the computer business, and its latest target for conquest is systems integration. As a step in this direction, Sun Microsystems Computer Corp has signed a service alliance agreement with Computer Sciences Corp, El Segundo, California to pursue systems integration business in the wireless telecommunications market. The agreement covers the full range of Computer Sciences’ software and services in systems integration and technology consulting and all hardware products provided by Sun. Both have agreements with Longmont, Colorado-based Coral Systems Inc, a specialist in Unix software for the wireless telephony world. Coral’s first product, FraudBuster, written to do just that, was launched in October.
