How to create a Load Balancer

Load Balancers are highly available and fully-managed Instances which allow you to distribute your workload across your various servers. They ensure the scaling of all your applications while securing their continuous availability, even in the event of heavy traffic. Load Balancers are commonly used to improve the performance and reliability of websites, applications, databases, and other services.

   • PAR1: Paris 1, France.
   • PAR2: Paris 2, France (innovative and sustainable Availability Zone).
   • AMS1: Amsterdam, The Netherlands.
   • AMS2: Amsterdam 2, The Netherlands.
   • AMS3: Amsterdam 3, The Netherlands.
   • WAW1: Warsaw, Poland.
   • WAW2: Warsaw, Poland.

5. Select a Load Balancer type, according to your needs in terms of bandwidth and whether you want to be able to attach backend servers from other cloud providers than Scaleway (Multi-cloud provider).

6. Select the accessibility of your Load Balancer. Choose either:

   • Private: A private Load Balancer will have no public IP address, and is only accessible from the Private Network(s) it is attached to. You can attach your Load Balancer to a Private Network after creation of the Load Balancer. Read more about private Load Balancers.
   • Public: A public Load Balancer is accessible from the internet via its public IP address. You must choose from the following IP options:
     • IPv4: A public IPv4 address is obligatory. You can either allocate a new IPv4 address, or select one of your existing flexible IPv4 addresses.
     • IPv6: You can optionally add a public IPv6 address in addition to the IPv4 address. You can either allocate a new IPv6 address, or select one of your existing flexible IPv6 addresses.

   Accessibility cannot be modified after creation of the Load Balancer. For more information about managing your Load Balancer’s public IPs, see our dedicated documentation.

• Click Create Load Balancer to finish now and create your Load Balancer without any frontends or backends. You can configure and add frontends and backends to your Load Balancer whenever you want after creation.
• Click Create and add front and backend to create your Load Balancer and also immediately proceed to configuring a frontend and backend for it. See how to create frontends and backends for help with this step.
