1) Create new EC2 Security group (reference ALB security group)

2) Create new shared-services-httpd EC2 instance

3) Populate proxy config from S3 bucket

4) Restart proxy service

5) Add new EC2 as a target to the ALB Target Group (group will now have 2 targets)

6) Remove old EC2 as a target from ALB Target Group (now there's only 1 target)

7) Destroy old shared-services-httpd EC2

Config File format check -s -T apache2ctl Status code

S3 Configuration Sync Implementation:

• Set up S3 bucket ucs-ss-config to store master config files
• Developed sync_apache_config.sh script that:
  • pulls config from S3
  • Validates Apache configuration
  • Updates local config if changes detected
  • Restarts Apache service when needed

Prepared cron job for automated syncing (not implemented yet) Status: Script tested in my environment. Need to test in a prod environment
