IBM is planning to expand its portfolio of software services for small firms employing up to 500 staff.
IBM said the services were for businesses that wanted to focus on growing, instead of running, their office systems.
Based on Linux, IBM Lotus Foundations is expected to provide server software that requires minimal technical expertise and is "autonomic" - able to manage and heal itself.
In addition, IBM has launched a managed beta of a web-delivered service codenamed "Bluehouse". Bluehouse provides extranet services that make it easy for small and medium-sized enterprises to collaborate securely beyond their organisational boundaries.
