Indigo is the successor technology and the consolidation of DCOM, COM+, Enterprise Services, Remoting, ASP.NET Web Services (ASMX), WSE, and the Microsoft Message Queue. It provides services for building distributed systems all the way from simplistic cross-appdomain message passing and ORPC to cross-platform, cross-organization, vastly distributed, service-oriented architectures providing reliable, secure, transactional, scalable and fast, online or offline, synchronous and asynchronous XML messaging.
I think is truly awesome, they (folks like Don Box, Doug Purdy, Steve Swartz, Scott Gellock, Omri Gazitt , Mike Vernal , John Lambert et al) have not just cooked up a brand new distributed computing platform but have built it on open standards and open technologies meaning that probably for the first time in decades there won't be artifical, politics induced divisions limiting a distributed computing technology to particular platforms or operating systems (i.e. like CORBA, DCOM & Java RMI). The extra goodness is that these open standards are all XML based so crazy XML geeks like me can do stuff like this or people like Sam Ruby can do stuff like that.
The next generation of DCOM, just that this time it interoperates with everyone regardless of what programming language or operating system they are running.
Fucking sweet.
