At Pixelpark, we use Solaris 10 as main production plattform for all our customers. All our web hosting customers need basic open source components like apache httpd, tomcat, mysql. Some of them are also using php, some are using mongrels, other glassfish V2 and so on. We always try to use the latest version of these components for security reasons and if we build high performance Web Sites, for performance. Today Solaris 10 U4 is offering outdated versions of apache, mysql and no php. Only Postgresql is up to date with Solaris 10 U4 (GREAT !!). Because we often (daily..) have to install these optimzied and up to date versions we have a couple of choices: Download binary distributions (like coolstack or from blastwave) or build these components on our own.
We hope, that the Sun Webstack project will bring us precompiled, optimized and up to date apache httpd, php, mongrel Versions with security relevant updates, soon. Maybe future Solaris 10 Updates (U5) will bring newer version of these main Web2.0 components that we do not have to compile, test, distribute, patch the components on our own.
