In Cloud computing, application and desktop delivery are the two emerging technologies that has reduced application and desktop computing costs and provided greater IT and user flexibility compared to traditional application and desktop management models. Among the various SaaS technologies, XenApp that allow numerous end users to connect to their corporate applications from any device. XenApp enables organizations to improve application management by centralizing applications in the datacenter to reduce costs, controlling and encrypting access to data and applications to improve security and delivering applications instantly to users anywhere by remotely accessing or streaming. As per old architecture we were using the oracle or MS-SQL in the backend of XenApp on Windows Server itself. But as we know for this we have to pay for database especially because we are not using it for any other purpose. And as we know windows is GUI based so running database over it consumes much more resources. So, it can lead to single point of failure. For this, this paper proposes a scheme for removing this problem by using the HA failover cluster based SQL server (mysql or Oracle) which will run over Linux box having concept of VIP (Virtual IP).

Learn about the next generation building block services available in Windows Azure that help to create connected, secure, and reliable services. With services such as Caching, Service Bus (relay, queues, and topics), and Access Control Services (ACS) developers can focus more on building great solutions and less on plumbing services necessary to do so. In this webcast, we will take a look at many of the additional services offered as part of Windows Azure. We'll see just how easy it can be to add scalable caching with Windows Azure Caching, create robust connected solutions with the Service Bus, and secure applications with ACS.
