In this chapter, we introduced Tuxedo as a client/server platform where you can build your distributed application, and its benefits. We also discussed Tuxedo architecture and how it has evolved over the past years. We briefly discussed the various components of Tuxedo, and finally saw how to install Tuxedo in various modes for different operating systems. I have mentioned some of the important guidelines and prerequisites to help you set up the environment for your Tuxedo installation. The installation is very interactive and simple, so I have not put in any screenshots or line-by-line instructions.
