Instructions
Managing your Load Balancer via the OVHcloud Control Panel
From the OVHcloud Control Panel, navigate to the Load Balancer section via the Network menu and select your OVHcloud Load Balancer service from the list.
The Home tab for the service will then appear:
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. |
| Graphics | In this section, you will see the graphs linked to service, by concurrent connections or requests per minute. |
| Information | Your IPv4 address and the Additional IPs linked to them, as well as the number of outgoing IPv4s (see more details by clicking the more options ... button). |
| Configuration | Here, you can customize the name of your solution (which will appear at the top of the left-hand column). The cipher(s) are customizable, as well as the data center where your Load Balancer is based |
| Commitment | Here, you will see the admin details for your solution. |
Managing front-ends
To add front-ends, go to the Front-ends tab and click Add a front-end.
The following form will 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, and SSL TCP (or TLS). |
| Port | Choose the listening port you wish to use. |
| Datacenter | Choose between your data center or all data centers to create your front-end. |
| Default server 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. You can expand this menu by clicking the Show button:
| Element | Purpose |
| Dedicated failover IP | List of Failover (Additional) IPs for remote servers. |
| Restrict access to IPs | List for restricting remote access to the Load Balancer, for IPv4 only |
| HTTP Redirection | Add an HTTP redirection URL |
| HTTP Header | Add an HTTP header here |
Managing clusters
To add a server cluster, go to the Server clusters tab, 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 mode | 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, or not at all. |
| Probe | Choosing and activating a probe. |
Managing your servers
Once you have created your server cluster, you just need to add servers to it. From the Server clusters tab, expand one of your server clusters and select the Add a server button.
As with the front-ends and the clusters, you have to provide some information and have advanced settings available to you.
You can expand the advanced settings by clicking the Show button. Details on all options are in the table below:
| 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 | Choose the probe that was validated when you created the cluster. |
| Encrypt requests with SSL | Encrypting requests with an SSL certificate. |
| Cookie | Add a customized 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. |
