Citrix have recently released a new edition to the XenApp family called XenApp Essentials. But what is the new flavour of XenApp and why has it been created? So, a brief history lesson. Microsoft have had for a number of years an Azure services called Azure RemoteApp. This was essentially Remote Desktop Services "as a service" from the the Azure cloud. It was cost effective, simple to deploy and had many of the great capabilities that only the cloud provides, such as auto scaling, usage based pricing, minimal management etc. It allowed organisations to publish applications (no desktops) directly to the users, without the need to manage an estate of virtual machines, and the need to build these out to meet the peak user load.
