The SpringSource online application management technology is expected to extend VMware's ability to offer cloud computing services to the enterprise.
SpringSource's developers are likely to help VMware get its vShere virtualisation hypervisor and management software to work with cloud applications.
VMware chief executive Paul Maritz said integration between the two would enable businesses to know what cloud applications are doing and to manage them.
The move could also mark the start of a developer community centred around vSphere, according to some analysts.
The deal is expected to close in September.
