AWS Regions & Availability Zones
22
Each region is a separate geographic area. Each region has multiple,
isolated locations known as Availability Zones. Choose specific regions to:
• Optimize latency
• Address regulatory requirements
• Create a point-of-presence (POP)

AMI
Amazon Machine Image (AMI) - template to
launch an Amazon EC2 instance with your
software
!
• Main component is a read-only filesystem containing
an operating system & additional software
!
• Compressed, encrypted, & uploaded into AWS S3 for
storage or as a volume in AWS EBS
!
• Run multiple instances from the same AMI

EBS-BackedInstance Store-Backed
Two Kinds of AMI Storage
• Boot in <5mins
• Limited to 10GB*
• Data on instance only
persists during the life of
the instance
• Instance attributes are fixed
for the life of the instance
• Cheaper only charged
runtime
• Boot in <1min
• Limited to 1TB
• Data persists after instance
termination
• Stop to change instance
settings
• Pay for runtime & storage
• All AWS Marketplace AMIs
are EBS-backed

Using an Instance
26
• Launching an instance: creating a virtual machine with
the specifications you provide.
!
• Terminating = destroying it, forever.
!
• Stopping = pausing. No data is lost and while stopped
you aren’t being charged.
!
• Starting = un-pausing.Your data should still be there.

Security Groups
27
Security Groups
• Acts as a firewall that controls the
traffic allowed into a group of
instances
!
• Add rules that govern inbound traffic;
can add or modify rules at any time
!
• Cannot map security groups across
regions
Rules
• Specify a certain protocol (TCP, UDP or ICMP)
• Specify destination port or ports (if the protocol isTCP or UDP)
• Specify source (IP address or addresses using CIDR notation*)
*combination of IP addresses represented by xxx.xxx.xxx.xxx/n where n is the number of 1 bits in the mask.
Example 192.168.12.0/23 represents address range 192.168.12.0- 192.168.13.255

28. copyright 2013
IP Addresses
28
Elastic IP Address (Static IP address):
• Associated with account, rather than a particular instance
• If your instance fails, can map its replacement to the same IP address
• Each account is limited to 5 elastic IP addresses
•You are charged $.01/hr when these IP addresses are not mapped to an instance
