Resource Model

Top objects in the resource model focused around config re-use and enterprise-targeted feature set:

1. Virtual-server: A virtual server is a traffic-management object represented by a set of IP address and a service. Clients send application traffic to a virtual server, which then directs the traffic according to your configuration instructions.

2. Application-profile: An application profile contains the configuration to manage application-specific network traffic in a variety of ways, depending on the protocols and services being used. For example, you can configure SSL client certificates before passing requests on to a target server. After configuring a profile, you associate the profile with a virtual server. The virtual server then processes traffic according to the values specified in the profile.

3. Pool: A load balancing pool is a logical set of devices, such as web servers, that you group together to receive and process traffic.

4. Member: A pool member represents the application running on backend server.

5. Monitor: A health monitor can monitor the health or performance of either pool members or servers.

Object Definition

This section illustrates the object scheme in JSON format by usng an example configuration:

1. 4x VirtualServers for HTTP, HTTPS, TCP and HTTP Redirection

2. 2x Pools, each has 2x members

3. 3x Monitors with different types
