alwaysFree, logging, OCI, shape, VM
OCI Always Free compute node has a restriction that isn’t clearly documented or obvious when you go to a instantiate such compute resources. That restriction is the absence of OCI Custom logging. This is a little surprising given that this capability is based on Fluentd and the compute footprint needed by Fluentd is so small. In the following screen shot, as you can see when configuring the compute, there is no reason to believe you can’t use OCI Logging for custom logs.
But when you go to configure the custom logging on your running compute, you can see that the feature is disabled with the message about the restriction. It would have been nice, to have the warning on the creation phase, as if I’d manually setup the VM then went to switch on OCI Logging knowing where I’d deployed my applications, I’d have wasted time in the setup.
Solution, use one of the AMD Flex or Previous Generation to minimize the footprint to your needs.
UPDATE 09th June 2021
We’ve been told that the this constraint has been addressed. In addition Oracle also introduced the new Ampere offering which allows for nodes with a form factor of upto 4 OCPU and 24GB of RAM using the new ARM chips. You can also use variations on this such as 4x 1 OCPU 6GB RAM
