Microsoft® Internet Security and Acceleration (ISA) Server 2006 provides controlled secure access between networks, and serves as a Web caching proxy providing fast Web response and offload capabilities, as well as secure Web publishing for remote access. Its multiple layered architecture and advanced policy engine provide granular control of the balance between the level of security you need and the resources that are required. As an edge server connecting many networks, ISA Server handles large amounts of traffic compared to other servers in an organization. For this reason, it is built for high performance. This article provides guidelines for deploying ISA Server with best performance and adequate capacity.
In most cases, the available network bandwidth and especially that of the Internet link can be secured by ISA Server running on available entry-level hardware. A typical default deployment of ISA Server securing outbound Web access for Hypertext Transfer Protocol (HTTP) traffic requires specific hardware configurations for various Internet links. These hardware configurations are shown in the following table. (For details, see Web Proxy Scenarios in this document.). For better speed & security, host your website on Dedicated server in India.
