Scaling

The institutional electronic mail service must be prepared to scale the technical and administrative infrastructure to support an eventual subscribed client base in the range of ten to seventy thousand individual clients. Special attention will be necessary in the areas of:

• administration
• client set-up and support
• domain-specific client customization requirements
• technical support
• address discovery (ie. internal & external directory)
• addressing & address policies
• message router architecture & message volume
• resource utilization
• performance
• dynamic configuration
• network access

As well as absolute size, consideration of the rate of expansion of the client base will present unique challenges in the provisioning of the service to clients. The service must be prepared to address this eventuality.
