NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more
Hold Proceed with caution
One of the goals of SOA has been to decouple services by exchanging human-readable business documents instead of programming parameters. However, in implementing SOA, many businesses have simply used web services to expose the underlying programming models of back-end systems. Procedure oriented integration is nothing more than remote procedure calls implemented via a different protocol. The consequences of this are additional layers of complexity with no improvement in business flexibility. To avoid this, implementers of SOA should first understand the business meaning of their services, then implement human-readable contracts that are independent of legacy system implementation.
