4. Solution: Web-Scale Computing
Scale capacity on demand
Turn fixed costs into variable costs
Simple APIs and conceptual models
Reduced time to market
Focus on product & core competencies
5. What is Cloud Computing?
Whether you are running applications that share photos or
support the critical operations of your business, you need rapid
access to flexible and low cost IT resources. The term "Cloud
Computing" refers to the on-demand delivery of IT resources
via the Internet with pay-as-you-go pricing.

9. Amazon Elastic Compute Cloud
A Distributed System you can actually use!
“Amazon Elastic Compute Cloud (Amazon
EC2) is a web service that provides resizable
compute capacity in the cloud. It is designed
to make web-scale computing easier for
EC2 is part of Amazon’s “pay per use” web
services for software development
10. What can you do with EC2?
Develop and run web-sites & web-services.
From a personal blog all the way up to a
large services like foursquare, netflix,
Do large-scale data processing (Like Dr.
Stiber’s GPU calculations, or the Global
Warming simulation Prof. Fukuda mentioned
in last lecture)
Allocate & De-allocate computing resources
11. Features :
Amazon Elastic Block Store
Elastic IP Addresses
Amazon Virtual Private Cloud
Elastic Load Balancing
High Performance Computing (HPC) Clusters
13. Amazon S3 (Amazon Simple Storage
Amazon S3 is storage for the Internet.
Amazon S3 provides a simple web services
interface that can be used to store and
retrieve any amount of data, at any time,
from anywhere on the web.
It gives any developer access to the same
highly scalable, reliable, secure, fast,
inexpensive infrastructure that Amazon uses
to run its own global network of web sites.
14. Amazon S3 Concepts
Opaque data to be stored (1 byte … 5 Gigabytes)
Authentication and access controls
Object container – any number of objects
100 buckets per account / buckets are “owned”
Unique object identifier within bucket
Up to 1024 bytes long
Flat object storage model
REST and SOAP
URL-Addressability – every object has a URL
Write, read, and delete objects containing from 1 byte to 5
terabytes of data each. The number of objects you can store is
Each object is stored in a bucket and retrieved via a unique,
developer-assigned key.A bucket can be stored in one of
several Regions. You can choose a Region to optimize for
latency or address regulatory requirements.
Authentication mechanisms are provided to ensure that data is
kept secure from unauthorized access. Objects can be made
private or public, and rights can be granted to specific users.
Reliability backed with the Amazon S3 Service Level
16. Common Use Cases:
Amazon S3 can be used to support a wide
variety of use cases, for example:
Content Storage and Distribution
Storage for Data Analysis
Backup, Archiving and Disaster Recovery
Static Website Hosting
18. Amazon Elastic Block Store (EBS)
Amazon Elastic Block Store (EBS) provides block
level storage volumes for use with Amazon EC2
Amazon EBS provides highly available, highly
reliable, predictable storage volumes that can be
attached to a running Amazon EC2 instance and
exposed as a device within the instance.
Amazon EBS is particularly suited for applications
that require a database, file system, or access to raw
block level storage.
Amazon EBS allows you to create storage volumes from 1 GB
to 1 TB that can be mounted as devices by Amazon EC2
Storage volumes behave like raw, unformatted block devices,
with user supplied device names and a block device interface.
Amazon EBS volumes are placed in a specific Availability Zone,
and can then be attached to instances also in that same
AWS also enables you to create new volumes from AWS
hosted public data sets.
Amazon EBS also provides the ability to create point-in-time
snapshots of volumes, which are persisted to Amazon S3.
These snapshots can be used as the starting point for new
Amazon EBS volumes, and protect data for long-term
21. Amazon VPC
Amazon Virtual Private Cloud (Amazon VPC) lets you provision
a logically isolated section of the Amazon Web Services (AWS)
Cloud where you can launch AWS resources in a virtual
network that you define.
You can easily customize the network configuration for your
Amazon VPC. For example, you can create a public-facing
subnet for your webservers that has access to the Internet, and
place your backend systems such as databases or application
servers in a private-facing subnet with no Internet access.
You have complete control over your virtual networking
environment, including selection of your own IP address range,
creation of subnets, and configuration of route tables and
Additionally, you can create a Hardware Virtual Private Network
(VPN) connection between your corporate datacenter and your
VPC and leverage the AWS cloud as an extension of your
Features and Benefits:
Multiple Connectivity Options
All the Scalability and Reliability of AWS
Host a simple, public-facing website
Host multi-tier web applications
Host scalable web applications in the AWS cloud that are
connected to your datacenter
Extend your corporate network into the cloud
