London-based MicroMuse Ltd has found that selling third party Sparc workstations alongside the original Sun Microsystems Inc kit was getting too complicated and has reined in the clone side of the business. Managing director Chris Dawes says the company decided that it should be concentrating on what it was doing with the box, rather than the box itself. MicroMuse has wound down the compatible side of its business, has become an authorised Sun reseller, and is focusing on delivering ‘complexity management’ middleware. By that, Dawes means software offerings – hidden from the user – that can manage and administer large networks of powerful workstations. The company’s first application is aimed at system adminstrators and developers and can analyse the performance and behaviour of distributed systems in a number of ways. An agent residing on each client provides the machine with operating parameters delivered to it from the application residing on an administrator’s host system. MicroMuse will be showing its stuff at this week’s Sun Expo UK show in Birmingham’s National Exhibition Centre.
