Scale up a cluster of 1C servers

When you zoom in, you can:

change a fixed configuration to an arbitrary configuration and vice versa;
change the number of resources in the current fixed or arbitrary configuration — vCPU, RAM, local disk size. The number of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.

In control panels go to Ready cloud 1C → 1C server cluster.
In the cluster row, look at its status — if the cluster is in status MAINTENANCEThe cluster is undergoing maintenance and is not available for scaling. Wait for the maintenance to complete. See the instructions for details Maintenance window.
Open the cluster page.
Click Scale up the cluster.
Select a different configuration: fixed or arbitrary. The number of vCPU and RAM can be decreased or increased, the disk size cannot be decreased.
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.
