VMware has held back on big ticket announcements for this year's VMworld contenting itself with showing previously-announced products and new free management tool.

The company has revealed further details on just two new products, set for release later this year and early next year, include CapacityIQ, which gives IT a historical view of capacity needs across virtualised resources to forecast capacity shortfalls and reclaim excess resources. CapacityIQ will be available in the fourth quarter of 2009.

The other unreleased product is ConfigControl, which automatically tracks the configuration of virtual machines and the relationship of VMs to underlying physical infrastructure, allowing IT to ensure compliance with business policies. ConfigControl will be available in the first half of next year.

Separately, VMware has announced a free web-based tool to help small and midsize businesses automate the installation and configuration of ESXi, the free version of VMware's hypervisor. The web-based service is called VMware Go and is in beta starting Monday with general availability scheduled for the fourth quarter of 2009.

VMworld could be the forum where VMware reveals more details about its plans for SpringSource, which will fit squarely into the company's cloud strategy. VMware has said it will combine its virtualisation technology with SpringSource's Java tools to create cloud-based platforms for the building and hosting of web applications.

Pund-IT analyst Charles King said he expects more details about SpringSource this week, and predicts that "some fairly major developers will climb on the SpringSource bandwagon."
