A facility for distributing transaction servers to process transactions of a number of different types is provided. The transaction types are organized into two or more priority levels ordered from highest to lowest. Each priority level has one or more transaction types. In the facility, a service level goal attribution system attributes a service level goal to each transaction type reflecting the level of service sought for transactions of the transaction type. An identification subsystem identifies transaction servers when they become available to process transactions. In response to each transaction server identified by the identification subsystem, a transaction server distribution subsystem assigns the identified transaction server to process a transaction of a type that needs an additional transaction server to meet its service level goal, and whose priority level is at least as high as that of any other transaction types that need an additional transaction server to meet its service level goal. When the assigned transaction servers complete processing of the transactions to which they are assigned, the identification subsystem reidentifies these transaction servers as again being available to process transactions.
