AWS Refresher 2013

• Download Amazon S3 Organizer(S3Fox) - S3Fox Organizer helps you organize/manage/store your files on Amazon S3 - https://addons.mozilla.org/en-us/firefox/addon/amazon-s3-organizers3fox/
• While connecting to S3 using Bucket Explorer, you have to provide these Access Key and Secret Key. Go to Security credentials > Access credentials > access keys > secret key - https://portal.aws.amazon.com/gp/aws/securityCredentials

• Using Firefox 20.0 on Mac OS 10.7 - S3 Fox Plugin doesnt work, so i switch browser.
  • WIndows: Cloudberry - http://www.cloudberrylab.com/
  • Mac: Cyberduck

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)

Web Services

• Command Line / API / SDK / Web Console
• Managment Interface > Cross Service Features > AAAAAAAAAAAAHHHH INFORMATION OVERLOAD

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.

• Go to AWS Management Console

• Click on S3 - https://console.aws.amazon.com/s3/home

• Create Bucket - this bucket must have a unique name around the entire world

• Try to Upload a File. Upload a simple image. The clock starts ticking, cost of storage is 12.5 cents per gigabyte (but wait! the first 5 gb is free each year).

• Go to Cloudfront > Create Distribution (Follow the dropdown menus)
• Note what your domain is (should be xxxxxx.cloudfront.net)
• Go back to your bucket under S3. Load it up. Select the bucket and click on actions to see Properties.
• Go to website > and tick Enabled.
• At this point the image you uploaded is now online at two places:
  • Bucket domain: dbbdupsingapore.s3-website-ap-southeast-1.amazonaws.com/merlion.jpg
  • Cloudfront: d3d7rogzicqdgz.cloudfront.net/merlion.jpg

• Go back to EC2.
• Press the Launch Instance button
• Request Instance
• Choose an AMI (Amazon Machine Image) - i chose linux
• Provide instance details.
• Create a keypair. If you lose the Key pair for an instance, you will never find it from amazon so your machine will not be available anymore ever again.
• You will receive a .pem (key access file). Save this in a safe place. Or back it up.
• Configure your Firewall. If you don't have one/don't know what it is, just choose the default security group.

Security Group

• Security Group - this part a bit over my head. basically you can control access and the firewall within 3 seconds and block IP if you are being hammered by someone.
• Now it is later. OH I UNDERSTAND NOW. You must set the ICMP and TCP with a new rule to allow all people to see it so that you can ping the IP!!!! Otherwise only a private group can access it...
• You should be able to ping the IP in terminal

Elastic IP

• Elastic IP - Create a new Elastic IP Address
• Generate a new Elastic IP instantly with two button clicks

• Right click and associate it with something else - your instance for example
• ping the IP - should work if security group is set correct to allow to ping

ssh

• Open terminal and find the pem file
• RUN THE FOLLOWING:
• chmod 600 yourkey.pem (change permissions for the pem file so u can run it)
• ssh -i yourkey.pem ec2-user@<YOUR ELASTIC IP> (connecting...)

start httpd

• sudo yum update (run some updates/??)
• sudo yum install httpd (install the web server)
• sudo apachectl start (start httpd)

Go to your elastic ip and you will see this screen

• you can login to sftp to see the files, remember to set connection type with private key (yourkey.pem)
• strangely i cannot add files in (WHY????)
• SOLUTION: sudo chmod 777 var/www/html/
• then you can drop in the file to the var/www/html folder!!

ITS ONLINE! Okay i spent the entire workshop doing this up to this point. Where is database how does i shot web now i have no idea?

database

• the class steamrollers on...
• Launch DB instance
• start mysql engine
• management options > backup / can roll back if you need
• DB security group setting to CIDR/IP
• OMG FLAILING ABOUT WILDLY
