Sprint replaced its costly proprietary middleware with JBoss Enterprise Middleware from Red Hat in order to significantly reduce costs while gaining more flexibility and agility. This allowed Sprint to save $4 million annually and refocus funds on business initiatives rather than just maintaining infrastructure. Sprint also used the migration as an opportunity to modernize its platform and infrastructure through virtualization and open source software. The project improved developer productivity and reduced time-to-market while establishing a more flexible and cost-effective foundation.
