Platform as a Service (PaaS) for Private Cloud
25 April 2012
 
Richard Watson  

Organizations are turning toward private platform as a service (PaaS) to gain the benefits of PaaS while avoiding the business and technical risks that come with public cloud computing. Private PaaS allows IT departments to retain control of security and performance characteristics while providing their developers with an agile environment for solution delivery. Enterprises also look to private PaaS as a lever to standardize application infrastructure. This assessment discusses the drivers for private PaaS and different implementation approaches and challenges that organizations will face in this pioneering stage.
