Containers
AWS container services offer the broadest choice of services to run your containers and run on the best global infrastructure, with 77 Availability Zones across 24 regions. AWS also provides strong security isolation between your containers, ensures you are running the latest security updates, and gives you the ability to set granular access permissions for every container.
