15. Risk
• Nothing to buy
• Cancel immediately
• Change instantly, even operating systems
• Throw it out
• Rebuild it instantly after testing

16. Reliability
• Based on enterprise grade hardware
• Designed for failures:
– Automatically spin up replacements
– Use multiple clouds

17. Cost
• “Turn off the lights” = turn off servers you aren’t
using
– Ex: Turn off development and test
environments
• Pay for only what you use
• No need to buy in advance
• Zero Capital Outlay
• No contracts

about the security in cloud
computing.
Some have said stored
information in the cloud is
