Issues Facing Developers
• 70% of Web Development Effort is “Muck”:
– Data Centers
– Bandwidth / Power / Cooling
– Operations
– Staffing
• Scaling is Difficult and Expensive:
– Large Up-Front Investment
– Invest Ahead of Demand
– Load is Unpredictable
Solution: Web-Scale Computing

Scale capacity on demand
Turn fixed costs into variable costs
Always available
Rock-solid reliability
Simple APIs and conceptual models
Cost-effective
Reduced time to market
Focus on product & core competencies
What is cloud computing
• the practice of using a network of remote
servers hosted on the Internet to store, manage,
and process data, rather than a local server or a
personal computer.
• An analogy: electricity services
– you simply plug into a vast electrical grid managed by
experts to get a low cost, relialbe power supply available to you with much greater efficiency than
you could generate on your own
Cloud Computing: Xaas
• IaaS: Infrastructure as a Service, AWS EC2
• PaaS: Platform as a Service. AWS Elastic
Beanstalk
• SaaS: Software as a Service. eg. google
doc/group
• DaaS: Desktop as a Service
– Amazon WorkSpaces, Vmware Horizon
Amazon Web Services (AWS)
Overview of Services
Amazon EC2 Functionality
• Select a pre-configured, templated image to get up and running
immediately. Or create an Amazon Machine Image (AMI) containing your
applications, libraries, data, and associated configuration settings.
• Configure security and network access on your Amazon EC2 instance.
• Choose which instance type(s) and operating system you want, then
start, terminate, and monitor as many instances of your AMI as needed,
using the web service APIs or the variety of management tools provided.
• Determine whether you want to run in multiple locations, utilize static IP
endpoints, or attach persistent block storage to your instances.
• Pay only for the resources that you actually consume, like instance-hours
or data transfer.
Elastic
• Elastic – Amazon EC2 enables you to increase or
decrease capacity within minutes, not hours or days.
– You can commission one, hundreds or even thousands of
server instances simultaneously.
– controlled with web service APIs, application can
automatically scale itself up and down depending on its
needs.
• Elastic Block Store vs. local Disk (not backup)
• Elastic IP Addresses vs. Static IP Addresses
– programmatically remapping your public IP addresses to any instance in your
account
Cost Saving Considerations
• On-Demand Instances – On-Demand Instances let you pay
for compute capacity by the hour with no long-term
commitments. This frees you from the costs and
complexities of planning, purchasing, and maintaining
hardware and transforms what are commonly large fixed
costs into much smaller variable costs.
• Reserved Instances – Reserved Instances give you the
option to make a low, one-time payment for each instance
you want to reserve and in turn receive a significant
discount on the hourly charge for that instance.
• Spot Instances – Spot Instances allow customers to bid on
unused Amazon EC2 capacity and run those instances for
as long as their bid exceeds the current Spot Price.
EC2 Features
• Multiple Locations: Regions/Availability Zones
– 8 regions: US East (Northern Virginia), US West (Oregon), US West
(Northern California), EU (Ireland), Asia Pacific (Singapore), Asia Pacific
(Tokyo), South America (Sao Paulo), Asia Pacific (Sydney)
– Inexpensive, low latency network connectivity to other Availability Zones
in the same Region, 99.95% SLA.

Amazon EC2 Concepts
• Amazon Machine Image (AMI):
–

–
–
Bootable root disk
Pre-defined or user-built
Catalog of user-built AMIs
OS: Fedora, Centos, Gentoo, Debian,
Ubuntu, Windows Server
– App Stack: LAMP, mpiBLAST, Hadoop
• Instance:
– Running copy of an AMI
– Launch in less than 2 minutes
– Start/stop programmatically
• Network Security Model:
– Explicit access control
– Security groups

T2 instances are Burstable Performance Instances that provide a baseline level of CPU
performance with the ability to burst above the baseline
This family includes the M3 instance types and provides a balance of compute, memory, and
network resources, and it is a good choice for many applications.
C3 instances are the latest generation of compute-optimized instances, providing customers with
the highest performing processors and the lowest price/compute performance available in EC2
currently.
R3 instances are optimized for memory-intensive applications and have the lowest cost per GiB of
RAM among Amazon EC2 instance types.
This family includes G2 instances intended for graphics and general purpose GPU compute
applications.
This family includes the High Storage Instances that provide very fast SSD-backed instance storage
optimized for very high random I/O performance, and provide high IOPS at a low cost.
HS1 instances provide very high storage density and high sequential read and write performance
per instance. It also offers the highest storage density among other EC2 instances and is lowest on
$/GB storage.
