Nowdays, business challenges require a more dynamic response to the increasingly demanding client and market requirements. These requirements are ultimately oriented to QoS (quality of service), collaboration, intelligent search, social web, information ubiquity and many things more.
Modern and visionary companies, should be prepared for these more exquisite and exigent crowd of cybernetic clients, that uses a more specialized criteria to analyze and select amongst a myriad of information and service providers.
Legacy companies should stop and watch their overall picture, and map themselves on the current technology scenario to create a strategy oriented to make the necessary changes and adaptations to their Enterprise Technology Stack (ETS), in order to face and survive the forthcoming challenges. Fortunately, Service Oriented Architecture (SOA) strategy, brings a light into the darkness to solve this kind of uncertainty to many companies.
The following picture, depicts a possible ETS model:
The middleware ESB, provides business flexibility and agility required to adapt to those new requirements and business models, by providing transparent binding and modification of business rules and processes. It also provides full support for Enterprise Application Integration (EAI), IT Governance, SOA Federation, Policy Reinforcement, Cross Security, QoS and lot more.
Web Applications will consume business rules and processes published on the ESB, so reinforcement of policies and security issues are delegated to this layer. This business logic is always ready to use and can be dynamically updated, changed and registered, so virtual services will keep working according to their original service level agreements, and applications will take advantage of the changing rules and processes, as business needs and consumers demand new marketing strategies.
