10. Serverless?

12. Just show up with some code and the platform handles:
● Operating System – no need to select, secure, configure,
administer or patch the OS
● Servers – no cost risk of over-provisioning and no
performance risk of under-provisioning
● Capacity – no need to monitor utilization and scale capacity
based on load
● High Availability – compute resources are available across
multiple AZs
