Cloudlet

What Is a Cloudlet?

A Cloudlet is the platform’s resource measurement unit. Each Cloudlet combines 128 MiB of RAM and 400 MHz of CPU.

Because Cloudlets are highly granular, the platform can assign capacity close to the actual requirements of each container. This supports usage-based pricing and reduces payment for unused resources.

One Cloudlet includes 128 MiB of RAM and 400 MHz of CPU capacity.
Measurement note: RAM is measured using binary units, where 1 MiB equals 1024 KiB. Disk space and network traffic are measured in decimal megabytes, where 1 MB equals 1000 KB.

Cloudlet Types

The platform provides two Cloudlet types for every server in an environment. They are configured through the Vertical Scaling per Node section of the topology wizard.

When a layer contains multiple nodes, the selected limits are applied equally to every instance in that layer.

Reserved and Dynamic Cloudlet controls in the topology wizard.
Reserved Cloudlets Capacity reserved in advance and charged regardless of actual usage. The number of reserved units can qualify for automatic discounts.
Dynamic Cloudlets Capacity added automatically when application demand increases and removed when the load falls. Charges are based on actual resource use.

The Dynamic Cloudlets slider defines the container’s scaling limit—the maximum number of Cloudlets that can be allocated automatically. This allows the application to handle unexpected traffic or processing spikes without manual intervention or special code.

Setting a Cloudlet scaling limit
Dynamic Cloudlets define the maximum automatic scaling capacity.
Recommended approach: Combine Reserved and Dynamic Cloudlets. Reserved units provide a stable baseline and discount benefits, while Dynamic units provide automatic vertical scaling during demand peaks.

Cloudlet Consumption Calculation

Cloudlet consumption is calculated hourly using two resource values:

  • RAM: the highest memory consumption recorded during the hour.
  • CPU: the average processor usage during the hour.

The platform charges the greater of the two values. RAM and CPU Cloudlet values are not added together.

ResourceMeasured UsageCloudlet Equivalent
Average CPU2400 MHz6 Cloudlets
Peak RAM1024 MiB8 Cloudlets
Chargeable UsageHigher of CPU or RAM8 Cloudlets

In this example, the account is charged for 8 Cloudlets rather than the combined total of 14. The final cost depends on the hosting provider’s tariff and can be reviewed in the platform’s quotas and pricing information.

Consumption Tracking

The dashboard’s Usage column shows current resource consumption for the complete environment and for each layer or node.

For historical analysis, use the Statistics section to review server consumption over a selected period. Applied charges can also be checked through the account’s billing history.
