TABLE OF CONTENTS The remainder of this book will focus on the sub-architecture of a service-oriented architecture. This chapter provides an approach to adopting Web Services and service-oriented architectures along with a vision of the future using standardized services. At the end, a case is made for getting started with Web Services sooner rather than later.
| Note | Continuing with my AV system analogy, the adoption of Web Services will be much like people treat their music collections. You start out with your own CDs and perhaps some cassette tapes. Commonly people make copies for their own use. They might load the music onto a hard drive and burn their own CDs to use in the car or elsewhere. This would be analogous to your internal development of services. At some point, you and a friend may exchange burned CDs. This would be analogous to a limited exchange with an external service. If you are really into music exchange, however, you are likely to get involved with Internet music file sharing at some point. This would be analogous to integrated exchanges with external services much like the story of C. R. s business trip. Many medium-sized and most larger organizations will go through these stages of adoption of a service-oriented architecture. ( Actually, this AV analogy does not fully realize the flexibility of a service-oriented architecture. To be as flexible as a service-oriented architecture, an AV system would need to support an integrated music experience. For example, you start playing a CD, then a live band... |
