Amazon Web Services Overview
Managing the unique and groundbreaking changes in both technology and business over the past decade has created an ongoing IT infrastructure challenge for many senior technology executives. Indeed, over the past ten years, the typical business application architecture has evolved from a desktop-centric installation, then to client/server solutions, and now to loosely coupled web services and service-oriented architectures (SOA). Each evolutionary step has built on the previous one while adding new challenges, dimensions, and opportunities for IT departments and their business partners. Recently, virtualization has become a widely accepted way to reduce operating costs and increase the reliability of enterprise IT. In addition, grid computing makes a completely new class of analytics, data crunching, and business intelligence tasks possible that were previously cost and time prohibitive. Along with these technology changes, the speed of innovation and unprecedented acceleration in the introduction of new products has fundamentally changed the way markets work. Along with the wide acceptance of software as a service (SaaS) offerings, these changes have paved the way for the latest IT infrastructure challenge: cloud computing.
