Info

This section describes target groups, which provide a flexible way to manage load balancing nodes or targets.
Abiquo manages target groups in AWS, OCI, and GCP.
For documentation of AWS application load balancers, see Manage application load balancers .
For information about load balancers in each provider, and documentation of traditional load balancers, see Manage load balancers.
For more details of load balancers in GCP, see Abiquo and Google Cloud Platform load balancers.
For more details of load balancers in OCI, see Abiquo and Oracle Cloud Infrastructure load balancers.

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

Privileges: Manage load balancers, Assign load balancers

Before you begin:

  1. Create targets, which may include subnets and IP addresses, or VMs 

To create an a target group:

  1. Go to myCloudVirtual datacenters → select a virtual datacenter in AWS → Network → Load balancing → Target groups

  2. Click the + add button

  3. Enter the target group details and assign targets as described below

  4. Click Save

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

General information for a Target group for GCP

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:

  • MANAGED_INSTANCE_GROUP

  • REGIONAL_MANAGED_INSTANCE_GROUP

But Abiquo onboards all target groups from GCP

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.
Keep the names to enter them in load balancers

Global network

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

(warning) 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

Name

The Name of the target group. GCP will only accept the following characters: a-z, 0-9 and

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

General information for a Target group

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

For more details see:

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 ("/").
See https://docs.aws.amazon.com/elasticloadbalancing/latest/application/target-group-health-checks.html#health-check-settings

Status code

  • OCI only: a request to the path of a healthy node will return this status code

Response body

  • OCI only: Optional; a request to the path of a healthy node will return this 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
