IBM's move to formally support Linux on the S/390 mainframe gives users an industrial-strength platform for running applications based on the open-source operating system, according to analysts.
But the traditional capacity-based licensing schemes associated with mainframe software, along with Linux's immaturity in enterprise environments, could slow the take-up, they added.
Furthermore, IBM last week said it will offer a full range of support services for Linux on the S/390.
Under the initiative, Linux for S/390 will be sold by Linux distribution vendors SuSE and TurboLinux.
IBM Global Services, will work in collaboration with SuSE and TurboLinux to offer technical support and middleware integration services.
