Configuring Load Balancers

Services may send traffic directly to a single backend service provider instance, or the traffic may be directed to a Load Balancer which will distribute traffic to multiple backend service instances. To access the Load Balancers list, select Load Balancers from the Menu.

To create a Load Balancer, select the Add action icon from the Load Balancers list. To edit an existing Load Balancer, select it from the List.

Load Balancer Properties

To add a server to the Load Balancer, select the Add action icon to the right of the Servers header. To remove a service, click the Delete action icon to the right of the server entry.

NameThe name of the Service. Names must begin with a letter, end with a letter or digit, be 64 characters or less in length, and contain only letters, digits, hyphens, underscores, or periods.
DescriptionA brief description of the Service.
HostThe host name to use when forwarding the request to the upstream server. This name will be used in the HTTP host header and as the SNI name for TLS connections. If omitted, the host name of the original request is used.
Balancing Method

One of:

  • Round Robin - Requests are distributed to servers using a weighted round-robin balancing method.
  • Least Connections - The request is sent to the server with the least average response time and least number of active connections, taking weight into account.
  • IP Hash - Requests are distributed to servers based on client IP address.
Upstream ProtocolWhether to use HTTP or HTTPS for the connection to the web service provider.
HostFor each server, the host name or IP address of the server
PortFor each server, the TCP/IP port of the server.
WeightFor each server, the weight of the server. Servers with higher weight values will receive more requests, proportional to its weight and the weight of other servers.
BackupIf selected, this server will not receive requests unless no other servers are available. 
OfflineIf selected, this server will not receive requests. This option may be used to temporarily remove an offline server from the balancer configuration without deleting it.
