• keep your VMs up to date!
• turning on/off automatic updates
• providing only private IP for VMs where public one is not needed, opening only necessary ports in security groups
• follow advices in security guidelines (yet to be published)

Deployment

• Do everything using code to reproduce
• Patch/update application and VMs periodically
• Keep logs 

Backups

• perform data backup
• refund the critical data and applications when possible
• VMs backup (but not rely only on it, perform data backup and automated deployment)

Remove VMs
