Architectural Tiers

The reference architecture is designed to support a tiered approach to implementation of hosted Microsoft Dynamics CRM services. The architecture is designed to support those hosters entering the market with plans to grow their services offers on pace with the growth of the business.

The architecture targets three design points, where the primary scale considerations are the size and number of organizations, and the number of users:

  • Entry Tier – Based on a single deployment group that supports up to 20 organizations and 200 users with minor provisions for asynchronous workloads and customizations.
  • Middle Tier – Based on a single deployment groups that supports up to 200 organizations and 2,000 users with moderate provisions for asynchronous workloads and customizations.
  • Upper Tier – Based on two deployment groups that support up to 400 organizations and 20,000 users with moderate provisions for asynchronous workloads and customizations.

    The hosted Dynamics CRM 2011 design defines the number of servers required for each design point. Service providers can use these examples as a starting point for planning how to grow their CRM service from one design point to the next.

    Three different reference deployment architectures, using the concept of deployment groups, gives service providers a way to choose an appropriate model based on knowledge of business plans and support factors. These reference tiers assume a concurrency rate of 60%. Given those assumptions, this table compares the number of deployment groups, the estimated organizations and users, and the required hardware for each tier.
