To reinforce enterprise-level security and maximize High Availability (HA) , an enterprise deployment topology typically requires a multi-tier architecture that is composed of the Client tier, the Web tier, the Application Server tier, and the Database tier. Each tier is a complete administration unit, which allows separate installation and configuration without affecting the other tiers.
A typical BAM HA topology is shown in the following diagram. As you can see, each tier can have its own HA configuration, which ensures that there is no single point of failure in the entire architecture:
For simplicity, this chapter only covers the HA configuration for Oracle BAM in the Application Server tier. After the completion of the BAM HA configuration, you are free to extend your current topology to include a load balancer, or even a Web Server in the Web tier.
You will learn the following topics in this chapter:
