case study 4

The Service-Oriented Architecture (SOA) strategy allows businesses and organizations to offer their products and services to customers and trading partners using a standards-based integration protocol. Web Services depends on SOA for delivery. SOA uses Extensible Markup Language (XML) to exchange data and information to its products and services consumers. One of the SOA characteristics is that the integration is loosely coupled, thus simplifying integration.

Write an eight to ten (8-10) page paper in which you:

1. Analyze five (5) ways in which SOA reduces the total cost of ownership (TCO). 
2. Examine five (5) ways in which using XML enables data and information exchange between clients and servers using Web Services in an SOA environment.
3. Compare and contrast the loosely coupled architecture to a tightly coupled architecture in terms of TCO, maintenance, and implementation issues.
4. Analyze three (3) advantages and three (3) disadvantages of using a standards-based integration strategy.
5. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.
