SOA filling the Gaps

IT implementations Complexity is growing consistently. The reasons for the growing complexity includes: additional types of functionality (e.g. BPM , Internal Social Networks as part of Enterprise 2.0 implementations etc.), Infrastructure heterogeneity, enhanced collaboration ( Social Networks , Instant Messaging , Contact Centers etc.), Usage of Web and Multi-Channel e.g. enhanced Cell Phones applications usage) and implementations beyond enterprise boundaries (e.g. Cloud Computing , Supply Chain Management) . The issue of complexity is described schematically in the illustration above. The idea is to reduce complexity and in the same time support growing heterogeneity and functionality. Abstractions are used frequently for hiding the complexity. For example SOA hides from Business users the technical details of service implementation; Virtualization hides the physical hardware configuration used by the Operating System instances. Load Balancing complexity is growing the same...
