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 |
Privilege: Manage load balancers, Assign load balancers
Before you begin:
- Create targets, which may include subnets and IP addresses, or VMs
To create an target group:
- Go to myCloud → Virtual datacenters → select a virtual datacenter in AWS → Network → Load balancing → Target groups
- Click the + add button
Enter the target group details and assign targets as described below
Click Save
Target group general info
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.
In the platform, you cannot create target groups of these types:
- MANAGED_INSTANCE_GROUP
- REGIONAL_MANAGED_INSTANCE_GROUP
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.
|
| Named ports | Enter a port Name to identify each Port in the target group. Keep the names to enter them in load balancers |
| 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 unmanaged instance 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 |
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
In AWS and OCI, you create a health check for each target group.
In GCP, you create a health check as part of the load balancer, and you can align it with the routing rules.
Screenshot: Create target group health check AWS
Screenshot: Create target group health check OCI. In OCI each target group must have its own health check.
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
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.
