Drive Down Costs Increase Service Revenues • Front end / back end • Architecture • Active Directory • Active / active clustering • Partitioned data store • Messaging – storage upsell • Web store services • Document services • Unified messaging • Conferencing • Wireless notification

  5. Developed with ASPs in Mind • Manageability • Security • High availability • Scalability

  6. Manageability • Microsoft Management Console (MMC) • Exchange System Manager (ESM) snap-in • Microsoft® Active Directory™ users and computers snap-in • Windows Management Instrumentation (WMI) • Third-party applications

  10. Directory Security • Restricts what users can see in Active Directory • Users only see information regarding their own company • Custom administration tools

  11. High Availability • Network load balancing cluster • Availability through redundancy and load distribution • Failover clustering • Allows failover to a secondary node

  12. Scalability via Front End / Back End Front end servers BE Machine B BE Machine A Shared Storage

  13. Flexibility of Clients • Microsoft® Outlook® 2000 • Outlook Web access • Outlook Express • Any POP3, IMAP4 clients

  21. Routing Group Design Paris (RG) NYC Routing Group London (RG) LA (RG)

  22. Public Folder Design • Multiple Top Level Hierarchies (TLHs) • User mailboxes associated with one PF tree • Peer level public folders • Each organization sees only its folders

  23. Managing Exchange 2000 • Microsoft Management Console (MMC) • Exchange System Manager (ESM) • Custom tools

  24. Managing Exchange 2000 (2) • Active Directory Services Interface (ADSI) • COM objects that represent objects in the directory • Variety of tools to interface with ADSI

  25. Managing Exchange 2000 (3) • Windows Management Instrumentation (WMI) • Three layer model • Managed system • Provider • WMI consumer • Collaboration Data Objects (CDO) / CDOEXM • Programmatic access to management • Use in conjunction with ADSI

  26. Other Services Instant Messaging Chat Conferencing

  27. Instant Messaging • IM Domain • Logical collection of users and servers • IM Home Server • Virtual server that hosts IM accounts • Maintains ‘presence’ information • IM Router • Receives messages and routes to appropriate home server

  28. Chat • Chat hosting strategies • Small companies • Community for each • Set access through access control lists (ACLs) • Large companies • Dedicated chat server • Approximately 20,000 concurrent connections/server

  29. Conferencing • Conferencing hosting considerations • Internet latency problems • Firewall issues • Quality of service (QOS) • Guarantees bandwidth • Support for real-time multimedia • Assures time transfer of large amounts of data

  30. AD SCO Ex SCO MAPS provisioning framework (XML abstraction) CDOEX DDNS ADSI Server apps (Exchange, SQL,etc) OS services and APIs Provisioning & Billing with MAPS ISV-developed provisioning, metering, billing, OSS frameworks
