newListener :: Listener Source #
Create a value of Listener
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:clientAffinity:Listener'
, listener_clientAffinity
- Client affinity lets you direct all requests from a user to the same
endpoint, if you have stateful applications, regardless of the port and
protocol of the client request. Client affinity gives you control over
whether to always route each client to the same specific endpoint.
Global Accelerator uses a consistent-flow hashing algorithm to choose
the optimal endpoint for a connection. If client affinity is NONE
,
Global Accelerator uses the "five-tuple" (5-tuple) properties—source
IP address, source port, destination IP address, destination port, and
protocol—to select the hash value, and then chooses the best endpoint.
However, with this setting, if someone uses different ports to connect
to Global Accelerator, their connections might not be always routed to
the same endpoint because the hash value changes.
If you want a given client to always be routed to the same endpoint, set
client affinity to SOURCE_IP
instead. When you use the SOURCE_IP
setting, Global Accelerator uses the "two-tuple" (2-tuple) properties—
source (client) IP address and destination IP address—to select the hash
value.
The default value is NONE
.
$sel:listenerArn:Listener'
, listener_listenerArn
- The Amazon Resource Name (ARN) of the listener.
$sel:portRanges:Listener'
, listener_portRanges
- The list of port ranges for the connections from clients to the
accelerator.
$sel:protocol:Listener'
, listener_protocol
- The protocol for the connections from clients to the accelerator.
