What is the maximum number of target service accounts allowed per firewall rule in Google Cloud?

In Google Cloud, a firewall rule can leverage target service accounts to specify which services or applications can utilize that rule. The maximum number of target service accounts permitted per firewall rule is 10. This allows for a flexible and secure way to define access controls for resources within your Google Cloud environment. By limiting the number of target service accounts, Google Cloud helps maintain a manageable and clear set of permissions, reducing the potential for configuration errors and improving overall security posture.

This limit ensures that administrators can effectively monitor and maintain firewall rules without overcrowding them with an excessive number of targets, thus helping to streamline network management and enhance performance.
