Inside Citrix - The FlexCast Management Architecture focuses on the FMA, mainly from an architectural point of view. It will discuss, in detail all of its main components and services, their primary roles and responsibilities, including some of the most common optional components, features and/or closely related technologies. From the basics to deep (er) dives where applicable, I will make sure to include something for everybody. Do note that this book is not meant as an installation and/or how-to manual, instead it will dive deeper into the FMA, the true foundation of Citrix XenDesktop and XenApp. Topics include but are not limited to: A deep dive into the FMA's main services, its evolution, a detailed overview on the user authentication, application enumeration and launch processes, Citrix printing, the ICA / HDX protocol, application delivery, MCS, PVS, troubleshooting, some history, fun facts and figures and (much) more. I have concluded each chapter with multiple key takeaways (a few hundred in total) and also included over 100 so-called FMA facts throughout the various chapters.
