This document provides an overview of Amazon Elastic Compute Cloud (EC2), a cloud computing service that allows users to launch server instances in Amazon's data centers. EC2 provides templates called Amazon Machine Images (AMIs) that contain pre-configured software. Users can launch instances of AMIs to replicate configurations across multiple servers. EC2 instances can be deployed and terminated on demand, while physical servers require regular maintenance. EC2 offers scalable, on-demand resources that users pay for based on usage, unlike physical servers which incur costs whether used or not. The document also briefly discusses other Amazon cloud services like S3, DynamoDB, and Elastic Beanstalk.

Amazon Cloud EC2
Amazon Elastic Compute Cloud (Amazon EC2) is a web
service (AWS) that provides resizable computing capacity—
literally server instances in Amazon's data centers—that you
use to build and host your software systems. With Amazon
EC2, you can get access to infrastructure resources using the
AWS Management Console, API actions, or command line
tools and utilities.

How does Amazon EC2 works
AMI: It Provides templates known as Amazon Machine Images
(AMIs) that contain pre-configured software such as an operating
system, application server, and applications. You use these
templates to launch your server instances. After you launch your
instance, you can use it just like a physical server
Replicate existing AMI: You can also launch multiple instances of
an AMI, thus replicating the same configuration across each of the
instances
Customized AMIs: In addition, members of the AWS developer
community have published their own custom Windows AMIs
Customize your own AMI: you can simply customize the resulting
Windows instances to provide the data or software you need each
time you launch an instance

Difference between Windows Server and
an EC2 Windows Instance:
Amazon EC2 Windows Instance Windows Server
Designed to be deployed and terminated on
demand.
Cannot be easily discarded after it is set up.
Resources and capacity are scalable Resources and capacity are physically limited.
You pay for the usage of the infrastructure.
Billing stops as soon as the instance is
terminated
You pay for the infrastructure, whether you
use it or not.
Does not occupy physical space and does
not require regular maintenance.
Occupies physical space and has to be
maintained on a regular basis.

PASS Example in Amazon
AWS Elastic Beanstalk:
AWS Elastic Beanstalk is an even easier way for you to quickly
deploy and manage applications in the AWS cloud.
AWS Elastic Beanstalk Functionality works
•For .NET Developers
•For PHP and Python Developers
•For Java Developers
•AWS Elastic Beanstalk Functionality

Other Cloud Services provided by Amazon
Amazon DynamoDB
Amazon DynamoDB is a fully managed NoSQL database service
Amazon Simple Storage Service
Amazon S3 is storage for the Internet. Amazon S3 can be used to
store and retrieve any amount of data, at any time, from
anywhere on the web.
Amazon SimpleDB
Amazon SimpleDB is a highly available and flexible non-relational
data store that offloads the work of database administration.
Developers simply store and query data items via web services
requests and Amazon SimpleDB does the rest.
