Cloud Providers
15
AWS offers 5x the compute capacity of next 14 cloud providers in the Gartner Magic Quadrant, combined. !
Analysts estimate AWS’ sales around $1.2 billion for Qi 2014, up from $750 million in Q1 2013 2

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-BackedTwo 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 is TCP 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
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
