AWS Elastic Beanstalk Gets Automatic Active Directory Domain Join for Windows
AWS Elastic Beanstalk now automatically joins Windows Server instances to your Active Directory domain without custom scripts—just configure a few options and you're done. Your instances get domain-joined at boot before app deployment, enabling Windows-integrated auth, group policy, and access to domain resources like SQL Server databases across all AWS Commercial Regions and GovCloud (US).
