Info

This page describes AWS application load balancers and links to how to create target groups for load balancers in all providers (AWS, OCI, GCP)

Introduction to application load balancers

Abiquo supports AWS Application load balancers. Application load balancers can send traffic to target groups, which contain IP addresses or VMs. Abiquo also continues to support Classic load balancers. See Manage load balancers

For a full description of Application load balancers, see the Amazon documentation at: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/introduction.html .

An application load balancer requires:

  1. At least one target group, which will receive traffic from the default conditional action

  2. At least two public subnets (with an Internet gateway) in different availability zones. See Create a private network .

You should create these elements before you create an application load balancer.

Create an application load balancer in AWS

Before you begin:

  1. Synchronize your virtual datacenters (including VMs, networks, firewalls, firewall rules, and load balancers)

  2. Create firewall policies for your VMs that allow your load balancers to access the VMs

  3. Create a target group with VMs or IP addresses

  4. Create subnets in at least two different availability zones

Panel

Privileges: Manage load balancers, Assign load balancers

To create an application load balancer:

  1. Go to Virtual datacenters → select a virtual datacenter → NetworkLoad balancing → Target groups

  2. Click the + add button to create a target group and complete the dialogs following the AWS documentation

  3. Go to Load balancing → Load balancers

  4. Click the + add button and complete the dialogs following the AWS documentation

Application load balancer general information

...

Field

Value

Name

The name of the load balancer.

  • Amazon will only accept the following characters: A-Z, a-z, 0-9 and "-", and you cannot modify the name

Type

For the Type select Application

Addresses

  • AWS: private or public IP

  • You may be able to change the address to another one in the same VDC by editing the load balancer

Subnets

Select at least two public subnets (with internet gateways) in different availability zones.

Application load balancer routing rules

After you enter general details, create routing rules.

...

Field

Value

Common protocols

Select one of the common protocols to load presets

Protocols

The incoming protocol to the load balancer. See AWS documentation for accepted values.

Ports

The incoming port to the load balancer. See AWS documentation for accepted values.

Target group

Select a target group

SSL Certificate

For secure connections (e.g. HTTPS), you can add an SSL certificate.

  • The platform will never store or validate the SSL certificate 

  • The platform will pass the certificate directly to the provider

Select an existing certificate or add a new one. Cannot be used in platform-only load balancers

Add

Click Add to include

...

the routing rule for the load balancer

To delete a routing rule, click the delete button beside the name of the routing rule in the list.

After you create the load balancer, you can edit it, and edit the conditional actions for routing rules.

Application load balancer SSL certificate

For TLS connections, enter a certificate.

...

Field

Value

Name

Name of the certificate

Certificate

The certificate contents

Intermediate certificate

An intermediate certificate can be issued by a provider to support older browsers that may not have all of the trusted root certificates for that provider, so that users will not receive invalid TLS warnings. If you have an intermediate certificate, add it at the same time as the certificate to ensure that a trusted-chain certificate is configured.

Private key

The RSA private key for the certificate

Application load balancer firewalls

Add firewalls to an application load balancer.

...

To add a firewall to your load balancer, select your firewall from the list of Firewalls available in your VDC for this provider. 

If a firewall is not on the list, it may not have been properly synchronized. In this case, click Cancel, synchronize firewalls, then start again to create a new load balancer.

...

Edit an application load balancer to set conditional actions

...

When you create an Application load balancer, each routing rule will redirect all traffic to the default target group. After you create a load balancer, you can edit it and modify the routing rules to manage the conditional actions.

To edit an application load balancer

...

:

  1. Go to myCloud view and select a virtual datacenter

  2. Go to Networks and select an application load balancer

  3. Click the pencil Edit button

Field

Value

Condition

  • Add one or more conditions for a single action

  • See AWS docs for more details.

Action

There are 3 actions available:

  • Forward: Route requests to the target groups specified by the "Forward to" action configuration

  • Redirect: Redirect the request based on the "Redirect" action configuration.

  • Fixed response: Returns a fixed response based on the "Fixed response" action configuration.

Conditional actions are "Listener rules" in AWS, see https://docs.aws.amazon.com/elasticloadbalancing/latest/application/listener-update-rules.html .

Target group

For a Forward action, select a Target group

Weight

For a Forward action, enter a Weight value between 0 and 999.

To edit a conditional action, click the pencil edit button on the left-hand side of the action in the list

To delete a conditional action, click the delete button on the left-hand side of the action in the list.

Use the up arrow and down arrow buttons to change the priority of the conditional actions.
