Practical Scenario: Overview

• Original setup

  • [ip1 ip2 ip3 ip4] web servers -- poorly balanced
  • [ip5 ip6] email relays -- only used 12 hours/day
  • [db1] database server --certain read/write intensive apps would benefit running locally on db1

• New mod_backhand setup

  • [ip1 ip2 ip3 ip4] web servers
    • Balancing the web servers with real resource information will more effectively utilize system resources
  • [ip5 ip6] web servers + email relays
    • email relays now contribute 12 hours/day each to the cluster
  • [db1] web server + read-write database
    • handling all certain read-write queries through local database server speeds responses.
