Create Auto scale
Auto-scale allows for the automatic resizing (increasing/decreasing) of your virtual server according to the intensity of your workload. You can specify the conditions for the auto-scaling to take place for the CPU, RAM, and disk. Two auto-scaling options are available:
Option 1: Scale up-down - Increasing/decreasing the ram and disk of the virtual serer.
Option 2: Scale in-out - Increasing/decreasing the number of virtual server (also called node). This option requires the use of a load balancer. Please see our Knowledgeable to find the instructions of setting up load balancers.
Remark: For Linux-based VSs only.
Create Auto scale up-down
1. On the page that follows, click the Overview tab, and then click Autoscaling.
2. Press the required tab - Memory Usage, Disk Usage or CPU Usage - to see the statistics for each type of resources.
Below you will see UP and DOWN autoscaling options. Move the slider to the right to add the autoscaling rule or move it to the left to remove the rule.
Add autoscaling rules as explained below:
Set autoscale up options:
- If RAM usage is above X% for a specific time period, add Y MB – but no more than Z MB in a 24 hour period.
- If CPU usage is above X % for a specific time period, add Y% - but no more than Z% in a 24 hour period.
- If disk usage is above X % for a specific time period, add Y GB - but no more than Z GB in a 24 hour period.
Set autoscale down options:
- If RAM usage is below X% for a specific time period, remove Y MB.
- If CPU usage is below X % for a specific time period, remove Y%.
- If disk usage is below X % for a specific time period, remove Y GB.
