Managing your Load Balancer via the Control Panel

On this page, you will see the following information:

Element	Purpose
Status	An overview of your Load Balancer with the IP, front-ends, functional clusters and servers added
Use	A summary of how to use your Load Balancer
Graphs	In this section, you will see the graphs linked to service, by concurrent connections or requests per minute
Information	Your IPv4 and IPv6 addresses and the Additional IPs linked to them, as well as the number of outgoing IPv4s (see more details by clicking on the `...` button)
Configuration	Here, you can customise the name of your solution (which will appear at the top of the left-hand column) The cipher(s) are customisable, as well as the availability zone where your Load Balancer is based
Subscription	Here, you will see the admin details for your solution

To add front-ends or Server clusters, simply click on their respective buttons. A form will then help you configure each part of your solution.

Managing front-ends

To add front-ends, simply go to the Front-ends section, and click Add a front-end. The following menu will then appear:

Details of front-end parts:

Element	Purpose
Name	If you want, you can choose a name for your front-end. This is very useful when you have several front-ends, so you can tell them apart quickly
Protocol	You can choose between HTTP, HTTPS, TCP, SSL TCP (or TLS) and UDP
Port	Choose the listening port you wish to use
Datacentre	Choose between your availability zone or all availability zones to create your front-end
Default cluster	If you have several clusters configured, you can choose one of them as a default for each front-end

You can also access advanced settings:

Element	Purpose
Dedicated Additional IP	List of Additional IPs for remote servers
Restrict access to IPs	List for restricting remote access to the Load Balancer, for IPv4 only
HTTP redirection	Add a HTTP redirection URL
HTTP header	Add a HTTP header here

Managing your clusters

To add a server cluster, simply go to the Server clusters section, and click Add a server cluster. You will get the same main options as for the front-end. However, the advanced options are different:

Element	Purpose
Distribution method	Choosing between Round-robin, First, Last, Source or URI for your IP load balancing
Track session	You can track sessions via Cookie or source IP, this can be defined here
Probe	Choosing and activating a probe

Managing your servers

Once you have created your server cluster, you just need to add servers to it. Details on these options are below, as well as advanced options:

Element	Purpose
Name	If you want, you can choose a name for your server. This is very useful when you have several servers, so you can tell them apart quickly
IPv4 address	Adding the IP address of the service that will act as a server
Port	Server port
Backup server	Selecting which server is a backup server
Use the server cluster’s probe	Choosing the probe that was validated when you created the cluster
Encrypt requests with SSL	Encrypting requests with an SSL certificate
Cookie	Add a customised session cookie
Certificate chain	Add a certificate chain
Balancing weight	Choose the balancing weight for the load balancer
PROXY Protocol version	Only if you have configured it, choose the version of the PROXY protocol you wish to use on the server. You can find more information on the PROXY protocol and how to use it with the OVHcloud Load Balancer in this guide.

Managing SSL certificates

You can add an SSL certificate to the Load Balancer in the SSL Certificate section. You have two options: you can order an SSL certificate from OVH, or add an external certificate.

OVHcloud SSL certificate

To order an SSL certificate, simply go to the SSL Certificate section, then click Order an SSL certificate and browse the options available:

Element	Purpose
Name	If you want, you can choose a name for your certificate. This is very useful when you have several certificates, so you can tell them apart quickly
Certificate type	Free (Let's Encrypt), Comodo DV or Comodo EV (For more details, see this page)
Fully Qualified Domain Name (FQDN)	Domain(s) concerned

Adding an external SSL certificate

If you already have your own SSL certificate, you can add it directly:

Element	Purpose
Name	If you want, you can choose a name for your certificate. This is very useful when you have several certificates, so you can tell them apart quickly
Private key	Field for entering the private key to add to the service
