PUSH Hosted Exchange as an online service rather than installing and operating it for themselves on in-house servers. These benefits include:

• Instant deployment, with no capital investment or complex project to install and configure Windows 2003 Server, Exchange 2003 Server and other required components.
• Lower TCO (Total Cost of Ownership), resulting from two primary factors. First, no need to make upfront capital investments or commitments to hardware, software and IT infrastructure. Instead, Hosted Exchange customers pay a simple monthly fee based on the number of users. The savings can be quite significant when the needs for a highly reliable (e.g. redundant servers, information backup, etc.) are considered. Second, a business using Hosted Exchange does not need to maintain the same level of in-house IT expertise to manage and maintain the environment.
• Enhanced security compared to an in-house installation, including automated and timely installation of anti-virus and other software updates.
• Increased levels of availability and performance due to the robust bandwidth and redundant network access of the hosting provider.
• High availability architecture of the hosting provider, which delivers higher reliability at a lower cost.
• Professional operations and support personnel with significant expertise and certifications in Exchange, Windows and all the other technologies needed to deliver service.
• Accessibility over the public Internet allows secure access for both internal and external scenarios and support for highly distributed, 'virtual' work situations. No requirement for complex VPN or Internet/Intranet solutions.
• Hassle-free operations mean no worrying about security patches, software updates/upgrades, monitoring, repairing failed hardware, adding capacity, etc.
• Daily backups stored off-site, ensuring business continuity and disaster recovery capabilities.
