Hey @kaz133,
At this time we do not currently offer the capability to pause or suspend instances.
We do however have persistent filesystems that you can attach to instances in specific regions if you wish to save data and attach them to an instance when needed. You can find more information on our docs page here:
https://docs.lambda.ai/public-cloud/filesystems/
Additionally, if you would like to reserve instances on the fly when needed, we recommend utilizing our Cloud API.
Our docs for the Cloud API can also be found below:
I hope this helps!
