A new load balancer has a routing type, a name and a sevalla.net domain, but no destinations: you add them from its Overview tab once it exists. This page covers the whole life of a load balancer, from creating it to deleting it.

​
Before you begin

  • The company needs a valid payment method: the dashboard doesn’t let you add destinations without one. See Payment methods and invoices.
  • Deploy the applications and static sites you want to route to first, so they have a domain.
  • You need permission to create load balancers in the company, or in at least one project. See Users and roles.

​
Create the load balancer

1

Open the create page

In the sidebar, click Load balancers, then click Create load balancer.
2

Choose the routing

Under Routing, click Default to spread traffic randomly, or Geo to send each visitor to the closest destination. See Routing.
3

Name it

Under Details, enter a Name, such as Storefront edge. If your company has projects, pick one in Project, or keep None (company level).
4

Create it

Check the Summary and the Estimated cost, then click Create load balancer.
The dashboard shows Load balancer created. and opens the load balancer’s Overview tab, where the diagram has an Add destination placeholder. Its <name>.sevalla.net domain is in the diagram, next to Domain.

Applications get their location’s coordinates automatically. An external service without coordinates has no location for Geo routing.

​
Disable or enable a destination

Disabling a destination stops its traffic but keeps it on the load balancer, so you can enable it again later.
1

Open the destination's menu

On the load balancer’s Overview tab, click … on the destination’s card, then click Disable (or Enable).
2

Confirm

Click Disable destination (or Enable destination).
A disabled destination’s card shows a red cross and Disabled, and its line in the diagram turns grey. The dashboard shows Destination disabled. or Destination enabled.

​
Remove a destination

1

Open the destination's menu

On the load balancer’s Overview tab, click … on the destination’s card, then click Remove from load balancer.
2

Confirm

Click Remove destination.
The card disappears and the dashboard shows Destination removed. The service itself isn’t changed: only the load balancer stops sending it traffic. To route to it again, add it as a new destination.

​
Update the routing or name

1

Open the sheet

On the load balancer’s Overview tab, click Settings on the load balancer’s card, or Load balancer settings in the diagram’s toolbar.
2

Change the values

In the Update load balancer sheet, choose a different Routing, or change the Name.
3

Save

Click Update load balancer.
The dashboard shows Load balancer updated., and the diagram shows the new routing. Changing the name doesn’t change the sevalla.net domain. A load balancer with Multi tenancy routing shows its routing as a note: you can only change its name. To move a load balancer into or out of a project, use the project’s Services tab. See Projects.

​
Delete a load balancer

1

Open the dialog

On the load balancer’s Overview tab, click More actions (the … in the diagram’s toolbar), then click Delete load balancer.
2

Confirm with its name

Type the load balancer’s name as the dialog shows it, such as storefront-edge-k2m9x, then click Delete load balancer.
The dashboard shows Load balancer deleted. and returns to the Load balancers list.
Deleting a load balancer stops all routing through it and removes its domains, custom domains included. You can’t undo it. The applications, static sites and other services it routed to keep running.

​
API and CLI

For an external service, use --service-type EXTERNAL --url https://origin.example.com, with --latitude and --longitude for Geo routing.
