I'm using google compute engine with a single VM instance (machine type: e2-custom-2-5632/skylake) that needs an upgrade. Services are bumping up against limits and throttling. I'm trying to purchase a committed use discount and upgrade the VM with additional RAM/memory without taking down all wordpress websites running on centOS.

Similar questions I've searched for Google Community Forums:

When does upgrading cause my services to stop or require a restart? Which upgrades require a restart? Do commitment use discounts require restarting services? If I upgrade VM ram do I have to restart services? If I follow a recommendation and upgrade via commitment use discount do I have to restart the server?

When does upgrading cause my services to stop or require a restart?

Changing CPU, memory, storage and configuration requires shutting down the VM first.

Do commitment use discounts require restarting services?

Committed use discounts are applied to the billing statement and do not affect individual virtual machines.

If I upgrade VM ram do I have to restart services?

Yes.

If I follow a recommendation and upgrade via commitment use discount do I have to restart the server?

Committed use discounts do not upgrade virtual machines, they only change pricing of existing virtual machines.
