RedHat has announced application stack with JBoss application server as one of the components along with others like Postgresql, mysql, Tomcat etc. This would benefit the corporate buyers who prefer to have IT deployments as a one-stop affair. Traditionally, deployment of open source based solutions has put the onus of integrating the various components like web server, application server, database on the system integrator or solution provider. Having a single company provide support for a 'stack' of components would assure buyers about one of the needling issues about support solution based on open source components. A single point of contact gives more confidence to buyers and will ease their concern about service and support.
