Scale 1C server cluster

warning

During 1C server cluster scaling, all associated info-bases may be temporarily unavailable.

We recommend scheduling maintenance during minimum cluster load and locking sessions for associated infobases.

When scaling, you can:

  • change the configuration;
  • change the line — from Standard to HighFreq and vice versa;
  • change the number of resources in the current fixed or custom configuration — vCPU, RAM, and network volume size. The number of vCPU and RAM can be decreased or increased, but the disk size cannot be decreased.
  1. Optional: set a session lock for the duration of the maintenance.
  2. In the control panel, in the top menu, click Products and select Turnkey 1C Cloud.
  3. Go to the 1C server cluster section.
  4. In the cluster row, check its status — if the cluster is in the MAINTENANCE status, maintenance is in progress and the cluster is unavailable for scaling. Wait for maintenance to finish. For details, see the Maintenance window instructions.
  5. Open the cluster page.
  6. Click Scale cluster.
  7. Select the configuration. The number of vCPUs and RAM can be increased or decreased; the disk size cannot be decreased.
  8. Specify the required amount of resources. The cluster uses 90% of the selected resource volume; the remaining 10% is reserved for the Apache web server, which handles web publications of info-bases.
  9. Click Save.
  10. Optional: if you set a session lock in step 1, remove it.
