Amazon Web Services 101, Cloud Computing Seminar, 14 June 2012

Where data is hosted and processed in the cloud because its faster!

Why use AWS

Elastic capacity
Quick, easy to deploy
No contract, no initial investment required, no capital exchange necessary
Pay as you go (pay for the machine ONLY when you use it, you don't need to own the infrastructure - easy to turn resource on and off)
Automation

Fun Fact: Dropbox is hosted and run entirely on AWS. Apparently Amazon S3 says their durability is 99.999999999 (11 nines). It says it will only lose one file in a million years.

AWS Infrastructure

Organised into multiple regions. Each regions have a multiple data centres. If one building burns down the other one still has the data. The customer does not feel interruptions and its highly redundant.
Start your instances at a region closer to yourself.
Edge Locations - these automatically help to distribute/serve the data (near Singapore there is Tokyo, Osaka, Hongkong) - a content delivery network

Setting up AWS Account

Go to http://aws.amazon.com/
You will need Name, Email, Credit Card (for laters), Phone number
It will call you to confirm (and you will recite the number back to it and IT WILL MAGICALLY KNOW)

Command Line / API / SDK / Web Console

Amazon Elastic Compute Cloud (EC2)

"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 developers.

Amazon EC2 presents a true virtual computing environment, allowing you to use web service interfaces to launch instances with a variety of operating systems, load them with your custom application environment, manage your network’s access permissions, and run your image using as many or few systems as you desire."
