What number signifies the soft limit of service projects in a shared VPC?

The number that signifies the soft limit of service projects in a shared VPC is 100. In Google Cloud, a shared VPC allows organizations to centralize their networking resources across multiple projects. The soft limit of 100 service projects indicates that while you are allowed to connect up to 100 projects to a shared VPC, you can request an increase if necessary.

This limit helps in managing the complexity of network configurations and ensuring optimal performance and security across the shared infrastructure. Understanding this limit is critical for cloud architects and network engineers as they design and implement scalable and efficient networking solutions in the Google Cloud environment.

Projects beyond this limit can still be accommodated, but they will require additional steps to request an increase in the quota, illustrating the importance of planning and resource management in cloud architecture.
