What is VPC sharing in AWS?

VPC sharing in AWS, or Virtual Private Cloud sharing, enables customers to share subnets with other AWS accounts within the same organization. This feature allows organizations to manage and utilize their resources more efficiently by permitting multiple accounts to access a common set of network resources while maintaining control and isolation at the subnet level. By allowing accounts within the same AWS organization to deploy resources in shared subnets, organizations can achieve better resource utilization, simplified networking, and cost savings.

This functionality is particularly useful for larger organizations where individual teams operate under different accounts but need to collaborate and share resources seamlessly. It promotes architectural best practices by enhancing the management of connectivity, security, and compliance across the involved accounts while retaining the operational agility that AWS services offer.
