Target groups provide a flexible way to manage load balancing nodes or targets.
Provider | Notes |
|---|---|
AWS | An Application load balancer sends traffic to a target group by default. You can create multiple target groups for each load balancer. |
OCI | Each target group belongs exclusively to a single load balancer. You must create at least one target group per load balancer |
GCP | You can create multiple target groups that can belong to multiple load balancers |

General information for a Target group table for Amazon
Field | Value |
|---|---|
Name | The name of the target group |
...
. Amazon will only accept the following characters: | |
Type | Select the target type of Private IP for a subnet address, or Virtual machine |
Protocol | Load balancers will use the Protocol to route traffic to the target group |
Port | Load balancers will use the Port to route traffic to the target group |
Protocol version | For HTTP and HTTPS protocols only, select a compatible version of the protocol |
Algorithm | For HTTP and HTTPS protocols only, for example, round robin or least_outstanding_requests |

As there are many types of target groups in Google Cloud, this page provides examples of two examples of target group types: instance groups and network endpoint groups.
| Note |
|---|
In the platform, you cannot create target groups of these types:
But Abiquo onboards all target groups from GCP |
Unmanaged instance group example
...
Field | Value |
|---|---|
Name | The Name of the target group. Google Cloud Platform will only accept the following characters: a-z, 0-9 and "-", and you cannot modify the name |
Type | For a typical load balancer with VMs attached, create an UNMANAGED_INSTANCE_GROUP. |
...
The other fields in this table are for an UNMANAGED_INSTANCE_GROUP | |
Named ports | Enter a port Name to identify each Port in the target group. |
Global network | The network that the VMs in the unmanaged instance group will use |
Subnet | A subnet of the global network that the VMs in the |
...
group will belong to | |
Location | The public cloud region that the VMs will belong to in the global network |
Availability zone | The availability zone to use in the global network |
GCE IP port target group example
Abiquo recommends GCE_IP_PORT target groups. This screenshot shows an INTERNET_IP_PORT target group. The INTERNET_IP_PORT target group is only available with classic load balancers.
...
Field | Value |
|---|---|
Name | The Name of the target group. GCP will only accept the following characters: a-z, 0-9 and "-", and you cannot modify the name |
Type | GCE_IP_PORT represents a Network Endpoint Group in GCP. It will load balance GCE IP addresses at the given port |
Port | The Port for communicating with the load balanced nodes |
Expand
In OCI, when you create a target group, it must belong to a load balancer. Each load balancer must have at least one target group.
Abiquo target groups are OCI backend sets.
...
Name | The Name of the target group |
Type | The DEFAULT type is for load balancers with nodes and the NETWORKING type is for network load balancers |
Algorithm | Select the algorithm for traffic distribution. The default is ROUND_ROBIN |
Target group health check
...
Screenshot: Create target group health check OCI. In OCI each target group must have its own health check.

...
Health check table for AWS and OCI
...
Field | Value |
|---|---|
Name | Name of the health check |
Common protocols | Select one of the most common protocols to load presets |
Protocol | The protocol with which the health check will be performed |
Port | The port to which the health check will be performed |
Path | The server path to check. |
...
In AWS, it must start with a slash ("/"). | |
Status code |
|
Response body |
|
Interval (sec) | The interval in seconds between health checks |
Timeout (sec) | The timeout in seconds after which an attempted health check will be considered unsuccessful |
Attempts | The number of attempts before the health check will be considered unsuccessful |
Target group targets
In AWS, when you create the target group you can add targets.
In OCI and GCP, to add targets, edit the target group

To add a target:
...
Select or enter a target and click Add
...
Enter an IP address and port, or select a VM, and click Add. When you have finished adding all of the targets, to create the target group, click Save
