How many target tags can be assigned per firewall rule at maximum?

The maximum number of target tags that can be assigned per firewall rule in Google Cloud is indeed 50. Target tags are used in firewall rules to specify which instances are affected by the rule. When you apply a tag to a firewall rule, it helps in categorizing and targeting the instances that the rule should apply to.

The limitation of 50 target tags ensures that the firewall configuration remains manageable and that the rules can be efficiently processed within the cloud environment. This design choice aims to maintain optimal performance and prevent overly complex configurations that could arise from assigning too many tags to a single rule.

In general, understanding the limitations associated with firewall rules and configurations in Google Cloud is crucial for designing secure and efficient network architectures. It empowers professionals to make decisions that align with best practices and system capabilities.
