What Are the Different Types of Web 2.0 Fonts?

Service-Oriented Architecture (SOA) is a component model that connects different functional units of an application (called services) through well-defined interfaces and contracts between these services. SOA technology has existed for more than 20 years, but has not been widely used. With the advent of Web services, SOA has finally ushered in its own "spring." The need for SOA stems from the need to make business IT systems more flexible to accommodate changes in the business. By allowing strongly defined relationships and specific implementations that are still flexible, IT systems can either leverage the capabilities of existing systems or be prepared to make changes later to meet their interaction needs.
