Solution Configuration 2

Solution Configuration 2, which is illustrated in the following figure, builds on Solution Configuration 1. It includes an external Web server, and an additional node dedicated to user traffic.

This configuration represents a moderate investment. There is minimal application clustering, low hardware cost, and no load balancing.

Solution Configuration 2 has the following features:

• Two physical servers

  • One for the application tier

  • One for the database tier

• External Web server sits on same host as the PPM nodes

• Two nodes dedicated to handling user traffic and provide failover

• One node dedicated to handling PPM services

• 10 to 12 GB RAM for the application tier (recommended)

• Solution Configuration 2 is ideal if your project must have the following:

  • Single sign-on support

  • Application level failover and load balancing
