Pools

What is a Pool?

Quite simply, a Pool is a collection of records that can be grouped together by record type (A, or AAAA, or TXT) that allow you to randomly distribute requests to different hosts (CNAMEs).

The following table displays the available pool types:

Record Type

Description

Resource Distribution (RD) Pool

A Resource Distribution (RD) Pool is simply a grouping of type A (IPv4 address) or type AAAA (IPv6 address) records, in which you can specify how the records answer a query.

SiteBacker (SB) Pool

A SiteBacker pool is a grouping of A or CNAME records that monitors your servers and redirects traffic to a host standby in case of server failure.

Traffic Controller (TC) Pool

A Traffic Controller (TC) pool is a grouping of A or CNAME records that extends SiteBacker as a Global Server Load Balancing solution.

Simple Load Balancing Pool (SLB)

Simple Load Balancing (SLB) Pools are used to define a pool of up to five IPv4 A records (Primary Records) or IPv6 AAAA records, an HTTP(S) monitor, and a backup (All Fail) IPv4 / IPv6 address. One resource record will be served based upon the Response Method that is configured.

Simple Failover (SF) Pool

Simple Monitor / Failover (SF) provides probing, notification and failover of a web site's IPv4 address record to one other IPv4 address.

Simple Monitoring is a subset of Simple Failover and Simple Load Balancing (SLB). You can run all the Simple Failover calls as a Simple Monitor call instead by ensuring that the Failover record information is removed from the body of the call. Examples will be provided for each call.

Directional (DIR) Pool

A Directional DNS Record represents a Directional Load Balancing (DIR) Pool, which is a collection of records configured to use your geographic location or Source IP address to determine a response.
