Azure Networking Fundamentals for DBAs – Everything you need to know in 20 minutes!
summary
Quick, practical rundown of Azure VNet basics with a live demo that builds a VNet, two subnets and an attached Network Security Group (NSG), adds inbound RDP and SQL (1433) rules, and shows a dangerous use of the service tag "Internet" is risky. Explains CIDR math with /16, /24, /25, /32 examples and the Azure quirk /24 => 256 addresses but Azure reserves 5 (available 251). Demo deploys successfully and attaches the NSG to a subnet so traffic filtering works as shown.
