This will be an information discussion about Hewlett-Packard’s (HP’s) Performance and Scalability testing of Microsoft’s IIS 7.0 Web Engine running on HP ProLiant Server platforms. HP is in the middle of testing how well IIS 7.0, running on Windows Server 2008, scales across multiple servers in a scale-out architecture, and how well it scales in a scale-up architecture when adding additional cores within a server. HP will provide preliminary server performance and scalability test results and server deployment recommendations based on characterization of different web service workloads and scenarios. HP will provide an overview of HP servers, network configurations and web workloads and show example deployments of web applications on HP servers. This session will provide technical performance and scalability data that can assist the audience in making decisions about how to design Web 2.0 architectures such as social-networking sites, wikis, blogs, and other Web 2.0 technologies on HP Technology.
