When VMware bought SpringSource they got three things:
1. Development Tools
2. Java application frameworks (runtime infrastructure for Java based applications)
3. Performance and Availability management tools that came as a result of SpringSource buying the assets of Hyperic earlier this year
Now that VMware owns Hyperic, it owns a monitoring solution that focuses upon the availability and resource utilization of servers, both physical and virtual. This puts VMware in the position to compete directly with third party vendors that have had this space largely to themselves, and will force these vendors to focus on new positioning and new differentiation in order to be competitive.
