Scale up a cluster of 1C servers

carefully

During scaling of a 1C server cluster, all information bases associated with it may be temporarily unavailable.

We recommend scheduling jobs during times of minimal cluster utilization and using session locking for linked information bases.

When you zoom in, you can:

  • reconfigure;
  • change the ruler — Standard to HighFreq and vice versa;
  • change the number of resources in the current fixed or arbitrary configuration — vCPU, RAM, network disk size. The number of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.
  1. Optional: set session lockout for the duration of the work.
  2. In the control panel, in the top menu, click Products → 1C Ready Cloud → 1C Server Cluster section.
  3. In the cluster row, look at the status of the cluster — if the cluster is in MAINTENANCE status, it is undergoing maintenance and the cluster is unavailable for scaling. Wait for the maintenance to complete. See the Maintenance Window instructions for more information.
  4. Open the cluster page.
  5. Click Scale Cluster.
  6. Select a configuration. The number of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.
  7. Specify the required amount of resources. 90% of the selected amount of RAM is used for cluster operation, the remaining 10% is reserved for Apache web server operation, which is responsible for maintenance of information base web publications.
  8. Click Save.
  9. Optional: If you set session locking in step 1, remove it.
