Summary

Added documentation about VPC hosting for web apps and updated URL formatting in links

Security assessment

The change adds guidance about hosting web apps in VPCs (a security best practice) but does not indicate a specific security vulnerability being addressed. VPC configuration helps improve network isolation but this is a general security feature documentation update.
