After years of uncertainty and experimentation, companies are incorporating the Internet into core business processes. But key to companies' success is the design and implementation of e-business platform infrastructure. For this infrastructure, companies often seek professional services organizations for expert information technology consulting and systems integration services.
Information resources reside in many disparate back-end systems.
Corporate mergers and acquisitions compound the problem. The biggest challenge is in creating application infrastructures that integrate functionality from these diverse systems. An N-tier environment, on the other hand, allows for distributed computing, with unlimited simultaneous input, access, and transactions. The business benefits of N-tier architectures are sufficient scalability and availability to provide a suitable platform for growth. The growth can be in subscriber volume as well as in new services.
