"Does SOI require a huge system rewrite or can we evolve our existing system?"
"What are the key pitfalls to be aware of when implementing SOI solutions?"
"What does service-oriented architecture mean for existing hub-and-spoke strategies?"
Ron Schmelzer: The answer is that in the short term, companies can apply SOI as a simple way of exposing existing interfaces. Many existing tools are trying to make this as easy and cost-effective as possible, and as such, adding SOAP interfaces to systems should be relatively easy nowadays. However, the big challenge is in creating service-oriented architectures. That may end up requiring the rearchitecting of systems, or probably the re-engineering of different integration paths. Basically, we need to get a grasp on granularity, service definition, and dynamic bind/find in order to make the most of SOI. If not, we'll be back to 1995 ;)
"ERP, EAI, etc. all take tremendous resources. How is SOI different from a business perspective?":
Ron Schmelzer: You are right, these all have tremendous implications, and unless people take a service-oriented approach to SOI, we will be stuck in the same hole. The idea is to be able to take advantage of the standards-based, loosely-coupled paradigm of SOI to simplify integration by making our systems more agile. If not, we risk falling into the same traps as before.
