Lecture 12: Cloud Computing-C

Lecture 12: Cloud Computing-C • Amazon Web Service Tutorial

Linux OS Info • This is a step-by-step visual guide to using AWS • Use this as a companion guide when you do your lab, BUT… • …MAKE SURE YOU UNDERSTAND WHAT’S GOING ON

Steps • Sign up for an AWS account • Sign in • Go to AWS Maintenance Console • Create an instance • Login to that instance • Do fun things • Logout • DELETE THAT INSTANCE

1. Sign Up For An Account • NEED TO DO THIS

2. Sign In • Return to http://aws.amazon.com/ • Returning user

3. AWS Management Console • Here’s your home screen • Click on “AWS Management Console”

3. AWS Management Console • Here’s another screen, but it’s not AWS Management Console yet • Sign in…

4. EC2 Cloud • This allows us access to all our services • All we care about is the EC2 cloud

5. Amazon EC2 Console Dashboard • This is our interface to the cloud • Let’s make an instance of a VM

6. Create An Instance • The following goes through the wizard • Let’s choose the ‘classic wizard’

6. Create An Instance • We need to pick an Amazon Machine Instance (AMI) • This is the selection of the OS that we’re choosing to run • This is the basic setup • We will configure our OS after boot • Configure network • Make users/groups • Install packages

6. Create An Instance

6. Create An Instance • You get this screen…

6. Create An Instance • Number of VMs to make

6. Create An Instance • Type of hardware

6. Create An Instance • “Give me my machine(s) now”

6. Create An Instance • Many AWS machines sit idle • They make no money when they’re idle • AWS allows you to pay a lower price for these idle machines • You set a price, and if you’re the “high bidder” at the time, it’s your machine to use • WARNING: Someone else can outbid you at any time and kick your processes off the machine!

6. Create An Instance • So, let’s pick “Launch Instance”

6. Create An Instance • Wait for these to be filled out…

6. Create An Instance • …then click continue

6. Create An Instance • We COULD have selected: • …a particular kernel setup • …a particular ramdisk • For our class, let’s leave those alone for now • Moving on…

6. Create An Instance • We could change our storage devices…but let’s not

6. Create An Instance • “Tags” are like AWS’s environmental variables • NOT really an EV inside the OS! • We can keep track of details about our (multiple) instances/VMs

6. Create An Instance • Fill out K/V pair based on lab • Hit Continue

6. Create An Instance • Authentication key pairs • Work just like our SSH lab

6. Create An Instance • “Security group” is just how your machine is configured wrt security

6. Create An Instance • Review your settings • If happy, click “launch”

6. Create An Instance • My machine is being set up • Note the instance ID! • You’ll need it if you have multiple instances running

6. Creating An Instance • In a moment, your instance will be ready • As soon as it’s up, your “processing time” starts • …even if you’re not logged in! • Do NOT let a machine sit idle • When you’re done, make sure you TERMINATE THE INSTANCE

6. Creating An Instance • Hit ‘refresh’

6. Create An Instance • Notice he’s running now • May take a minute depending on config

7. View Your Instance • Click one to see your instance

7. View Your Instance • Here it is!

7. View Your Instance • Click on instance, and then find “public DNS” in details below

8. Connect To Instance

8. Connect To Instance • Pick how you want to connect

8. Connect To Instance • We’re now connected to our VM

9. Do Your Thing

10. Terminate Instance • Choose an Instance Action of “Terminate”

10. Terminate Instance • Confirm the termination

11. Verify Termination • If you didn’t terminate, you’re still being billed!!!

Wrap Up • This was a GUIDE to running AWS • Your lab procedure will be slightly different than this • If all you do is follow this guide, your lab grade will be quite low… • …and you will have deserved it
