To restrict access to specific sensitive log fields (e.g. PII), Google Cloud offers Log field-level access control. You can apply field-level restrictions and then assign the Log Field Accessor role only to trusted personnel.

“You can use field-level access control to restrict access to certain fields in your logs. For example, you can restrict access to jsonPayload.user_email.”

— Cloud Logging Field-Level Access

“Grant the roles/logging.fieldAccessor role to principals that require access to these restricted fields.”

— Log Field Accessor Role

This lets your operations team continue using logs while ensuring that PII is only visible to the security team, fulfilling your compliance obligations.

OOMKilled means the containers exceeded their allocated memory. Since the HPA isn't scaling up (stuck at min), this indicates the issue is not scale-related but container memory limits are too low.

"Pods terminated with OOMKilled have exceeded their memory limits. You should adjust the container's resource requests and limits."

— Kubernetes OOMKill Debug Guide

Scaling the number of replicas won't help if each replica crashes. You need to increase memory limits so pods can run reliably before autoscaling can even work.

The best option for determining whether the increase in availability is worth the investment for a single year of usage is to calculate the value of improved availability to be $900, and determine that the increase in availability is not worth the investment. To calculate the value of improved availability, we can use the following formula:

Value of improved availability = Revenue * (New availability - Current availability)

Plugging in the given numbers, we get:

Value of improved availability = $1,000,000 * (0.9999 - 0.999) = $900

Since the value of improved availability is less than the investment of $2,000, we can conclude that the increase in availability is not worth the investment.
