Manage servers in the target group

Add the server to the target group⁠

  1. In the dashboard, on the top menu, click Products and select Cloud Servers.
  2. Go to Balancers → Target Groups tab.
  3. Open the landing page.
  4. In the Servers block, click Add Server.
  5. Select a server.
  6. Select an IP address.
  7. A group port value will be automatically selected for the server — change it if necessary.
  8. Specify the server weight — this is a proportional measure, denotes the fraction of requests that the server handles. If the weights are the same, the servers serve the same number of requests. If, for example, there is one server in a group with weight "2" and two servers with weight "1", the first server will receive 50% of all requests and the other two will receive 25% each. The maximum weight value is 256.
  9. If you want to make the server redundant so that it will accept requests only when the other servers in the group are unavailable, check the Backup checkbox.
  10. Click .

Make a server in a group redundant⁠

A cloud server in the target group can be made redundant — it will be included in the group, but will stop accepting requests as long as at least one server in the group is available. If all servers in the group are unavailable, the standby server will come online.

  1. In the dashboard, on the top menu, click Products and select Cloud Servers.
  2. Go to Balancers → Target Groups tab.
  3. Open the landing page.
  4. In the Servers block, in the Server row, enable the toggle switch in the Backup column.

Suspend a server in a group⁠

The server can be suspended when work is performed on the server, for example, when an application is updated or rebooted — the server will temporarily not process requests for this target group. The server itself will continue to work.

There is no need to remove the server from the target group — it will continue to process traffic as soon as you reactivate it.

  1. In the dashboard, on the top menu, click Products and select Cloud Servers.
  2. Go to Balancers → Target Groups tab.
  3. Open the landing page.
  4. In the Servers block, in the server menu, select Do not accept requests.

Resume server operation in the group⁠

  1. In the dashboard, on the top menu, click Products and select Cloud Servers.
  2. Go to Balancers → Target Groups tab.
  3. Open the landing page.
  4. In the Servers block, in the server menu, select Accept Requests.

Remove the server from the target group⁠

If you remove a server from the target group, it will stop accepting requests. The server itself will not be deleted.

  1. In the Control panel, on the top menu, click Products and select Cloud Servers.
  2. Go to Balancers → Target Groups tab.
  3. Open the landing page.
  4. In the Servers block, in the server menu, select Remove server from group.
