https://docs.cloud.oracle.com/en-us/iaas/Content/Functions/Reference/functionsmetrics.htm you can monitor the health, capacity, and performance of functions you've deployed to Oracle Functions by using metrics Oracle Functions monitors function execution, and collects and reports metrics such as:
The number of times a function is invoked.
The length of time a function runs for.
The number of times a function failed.
The number of requests to invoke a function that returned a '429 Too Many Requests' error in the response (known as 'throttled function invocations').

Explanation
NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels for IP addresses or CIDR blocks connecting to file systems through exports in a mount target. Access can be restricted so that each client's file system is inaccessible and invisible to the other, providing better security controls in multi-tenant environments.
Using NFS export option access controls, you can limit clients' ability to connect to the file system and view or write data. For example, if you want to allow clients to consume but not update resources in your file system, you can set access to Read Only. You can also reduce client root access to your file systems and map specified User IDs (UIDs) and Group IDs (GIDs) to an anonymous UID/GID of your choice.

OCI Traffic Management Steering Policies can account for health of answers to provide failover capabilities, provide the ability to load balance traffic across multiple resources, and account for the location where the query was initiated to provide a simple, flexible and powerful mechanism to efficiently steer DNS traffic.
Public Load Balancer Accepts traffic from the internet using a public IP address that serves as the entry point for incoming traffic. Load balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain

You can define the members of the dynamic group based on the following:
- compartment ID
- instance ID
- tag namespace and tag key
- tag namespace, tag key, and tag value
Supported variables are:
instance.compartment.id - the OCID of the compartment where the instance resides instance.id - the OCID of the instance tag.<tagnamespace>.<tagkey>.value - the tag namespace and tag key. For example, tag.department.operations.value .
tag.<tagnamespace>.<tagkey>.value='<tagvalue>' - the tag namespace, tag key, and tag value. For example, tag.department.operations.value='45'
