Intermittent cloud servers
An interruptible cloud server is a cloud server that runs for no more than 24 hours after creation and can be stopped by Selectel at any time, for example, if the virtual host does not have enough resources for other cloud servers.
When a system interruption occurs, the cloud server is not deleted — it stops and goes to EXPIRED
status.After the interruption, the server can be restored.On a server with a network boot disk, all data is saved, with a local boot disk, all data is deleted.
Interruptible servers support all the features that are available for regular cloud servers while costing less.
You can make a cloud server interruptible when you create a server or change the type of an existing server.You can make a server of any configuration interruptible .
Tasks to be solved
Suitable for fault-tolerant systems where multiple servers are used and when some of them fail, the load is redistributed to other servers:
- for parallel batch data processing;
- CI/CD testing;
- Hadoop and Kubernetes projects;
- scaling fault-tolerant web services during peak load times;
- any fault-tolerant projects with variable load.
Limits and restrictions
Interruptible cloud servers are temporarily available only in the ru-7 pool.
We do not guarantee the same level of availability as conventional cloud servers — interrupted servers are not subject to cloud platform SLAs.
Cost
The cost of an interruptible server is on average 70% lower than the cost of a regular cloud server with the same configuration.
During operation, intermittent cloud servers are paid for using the cloud platform payment model.
After the interruption:
- vCPU, RAM, GPU, local disks are no longer charged starting from the next hour after the stop;
- public IP addresses, public subnets and network disks continue to be charged.
