# Web DBI - Too many connections

- ## Busy web sites run many web server processes

  - possibly on many machines...
  - Machines * Processes = Many Connections
  - Machines * Processes * Users = Very Many Connections

- ## Limits on database connections

  - Memory consumption of web server processes
  - Database server resources (memory, threads etc.) or licensing

- ## So… partition web servers into General and Database groups

- ## Direct requests that require database access to the Database web servers

  - Use Reverse Proxy / Redirect / Rewrite to achieve this
  - Allows each subset of servers to be tuned to best fit workload
  - And/or be run on appropriate hardware platforms
