The SOA Practical Guide supports optimizing an EA Team's method to support an architecture based on services, which mirror real-world business activities, comprising the enterprise business processes.
Building an enterprise architecture around services, business and information services, supports enterprise agility. Service Oriented Architecture (SOA) isolates activity allowing different services to be changes with minimal enterprise impact.
SOA Practical Guide
SOA Practical Guide adapts the best practice processes for the development, management, governance, and adoption of enterprise architecture and applies it specifically to SOA.
This Guide provides specific information on the adaption of TOGAF to develop SOA in the following areas:
Use of the Architecture Development Method to develop Service Oriented Architectures
Modification of the Content Meta-model for SOA
Adoption of SOA-specific general and technical reference models
Adoption of SOA-specific governance requirements
Adoption of SOA-specific maturity models
The SOA Practical Guide focuses on services. A service is a logical representation of a repeatable business activity. They have a specified outcome (e.g., check customer credit; provide weather data, consolidate drilling reports, etc.).
May be composed of other services
Is a “black box” to consumers of the service
The SOA Practical Guide is written for EA Team Leaders. It is a good example of configuring TOGAF. The advice is useful for enterprise architects seeking better understanding of developing an optimal target architecture.
The SOA Practical Guide is a TOGAF Series Guide and is part of the TOGAF Standard.
