Web services are no longer just hype — they are being sanctioned by the industry on two fronts, standards and products. IBM is investing time, talent, and money on both these fronts, establishing itself as an industry leader. Web services are being developed as the foundation of a new generation of business-to-business and application integration architectures. This places Web services technologies in a business critical role within most enterprises. The corollary to this is that the Web services and the applications that use them must be manageable, from end to end, through the firewalls. The business-to-business Web services applications require management solutions in kind. They must be platform and technology agnostic, available through firewall, internet friendly, and flexible. This presents new challenges and opportunities to management vendors.
