EC2 instance tenancy defines whether your virtual machines run on hardware shared with other AWS customers or on hardware dedicated exclusively to your account. This choice is not merely a technical detail; it is […]

While essential for controlling traffic, they often become a source of significant operational complexity and security risk. As teams add rules for development, testing, and production access, the number of permissions […]
