Some of the competing services in the IPaaS space are Software AG, TIBCO, Jitterbit, Informatica. (Thanks to Dave Masefield for giving me this quick list).
Interesting service that still has alot of hype about how easy it is to integrate on-premise and cloud based services (which we know is typically harder than expected), but still a valid service that I am sure will grow as more cloud based services are used and trusted.
Have an outstanding day!
