Enterprise Management Associates (EMA) has conducted extensive research investigating the integration and management challenges created by the convergence of on-premise and public cloud-hosted applications. Research conducted in mid-2012 uncovered some compelling statistics about the role of cloud integration in today's companies:
- Nearly 50 per cent of the companies surveyed have already deployed tiered transactions spanning public Cloud and on-premise computing environments (one form of "hybrid cloud")
- Approximately 35 per cent have integrated (or are in the process of integrating) multiple Software as a Service (SaaS) applications
As one IT professional put it, "Everything is connected to everything." Because of this fact, any discussion of public cloud as a standalone technology is outmoded. Few modern on-premise applications exist as "silos," and the same is true of cloud-delivered applications.
While the topic of integration has become newly relevant as cloud gains momentum, the word "integration" has traditionally been associated with complex middleware platforms, such as Enterprise Service Bus (ESB), messaging, and Enterprise Application Integration (EAI) technologies. These technologies require highly specialised skills to deploy and support, and many smaller companies lack and often can't afford employees with these skillsets. Cloud has generated a new set of integration requirements to support new use cases.
