How is ERS different from ASF Apache or Tomcat?
ERS differs from ASF Apache and Tomcat in two major ways. First, SpringSource provides binary patches and bug fixes for ERS Apache and Tomcat. The ASF tends to not create patches for existing versions, but instead will roll bug and security fixes into new versions. This means that to get a fix you need to wait for the next version to be released, and then you must upgrade your entire server. SpringSource provides value by backporting these fixes and compiling them into binary patches that can be dropped into an existing installation, fixing only the issues and not requiring a full version upgrade. The second major difference is that ERS supports multiple instances of Apache and/or Tomcat with a single installation. This means a single set of binaries can run any number of Apache and Tomcat instances on a single operating system. This provides value in a number of ways, from allowing administrators to test new configuration changes without touching current system configuration, to allow
