We have a discussion list:

I virnet@lists.inf.ethz.ch

Assignment 2 - Cloud computing

I

Goals

I Gain experience using EC2 services

I Deploy an application over the IaaS

I Try auto-scaling mechanisms - Boto library and AWSCli interface

I Benchmarking on the EC2 Infrastructure

I

Structure of the homework

I Get credentials to log-in to the cloud

I Part A - 1st week - Boto + EC2 playing + proposal

I Part B - 2nd week - Benchmarking

I Part C - 3rd week - Auto-scaling

I _{End ABC - deliver report A2ABC}

I Part D - 4th week - Auto-evaluation + Billing

I Final submit

Get credentials and how to use them

I

Get credentials:

I Hw folder: https://svn.systems.inf.ethz.ch/svn/ systems/virnet13_students/trunk/NAME/A2ABC

I Under your A2ABC, you should find the file credentials containing:

I _{user name,access key id,secret access key,password}

I

How to use them:

I Amazon dashboard:

I Login to Amazon EC2 using: username, password

I URL :

https://ethz-virnet13.signin.aws.amazon.com/console I AWSCli and Boto APIs

I _{username, access key id, secret access key} I ... Explained later in the slides

Part A - 1st week

I

AWSCli + Boto

I

EC2 dashboard

I

Submit proposal:

I Next week consultation (29th Oct)

I Or by e-mail before (28th Oct - 11:59AM)

I

The proposal should cover the important details of how you

intend to proceed with Parts B and C, in particular:

hypotheses.

I Planned modifications to your overlay network.

I Auto-scaling: describe your strategy, for example, when and how is it triggered?

Environment setup

I

Install anaconda python:

I https://store.continuum.io/cshop/academicanaconda

I download it free and install it

Configure AWSCli

I

URL: http://aws.amazon.com/cli/

I

To install:

I pip install awscli (you installed pip following previous slide)

I

Link AWSCli with your Amazon account:

mkdir -p ˜/.aws/

vim ˜/.aws/config

cat ˜/.aws/config

[default]

region = us-west-2

aws_access_key_id=your access_key_id

aws_secret_access_key=your

secret_access_key

I

For the meaning of access key id and secret access key see

slide above

Test AWSCli connection

I

Create KeyPair file mykeypair.pem :

aws ec2 create-key-pair --key-name mykey > ˜/mykey.pem

I

Result: In the EC2 dashboard - Key Pairs page you will see

the pair with the name you just created:

I https://console.aws.amazon.com/ec2/v2/home?region= us-west-2#KeyPairs:

I

This task can be done directly from the EC2 dashboard.

However, we would like you to try out the command line

interface because is will help you automatize things when

doing the benchmarking tests.

Configure Python boto

I

URL: http://boto.cloudhackers.com/en/latest/

-Check EC2 and Auto-Scaling links

I

You should already have it installed

I

Otherwise: pip install boto

I

Link Boto python with your Amazon account:

vim ˜/.boto

cat ˜/.aws/config

[Credentials]

aws_access_key_id=your access_key_id

aws_secret_access_key=your

secret_access_key

I

For the meaning of access key id and secret access key see

slide above

Test Boto Cli connection

I

One of the most common things to do using the Boto Cli API

will be to create instances. Here is an example on how to do

this:

cat create instance.py

#!/usr/bin/env python

import boto.ec2

conn = boto.ec2.connect to region("us-west-2")

conn.run instances(

’ami-d03ea1e0’,

key name=’mykey’,

instance type=’t1.micro’)

I

By running this script you launch a new instance. Check EC2

Test Boto Cli connection (cont.)

I

In the code from previous slide:

I amid03ea1e0, stands for Amazon Machine Images, further reference - https://aws.amazon.com/amis. To get the code of such an image go to the Launch button of each image.

I mykeypair, the key we have created with AWSCli

I t1.micro, type of instance, further reference - http://aws. amazon.com/ec2/instance-types/#instance-details

EC2 dashboard - Remember

I

Management access rights to your colleagues instances.

I

$ 100 recommended for each students

I Eg. run 15 large instances for one day each, or 6 micro instances continually for a month.

Part B,C - 2nd and 3rd week

I

Main objectives:

I Explore benchmarking

I Overlay Network Integration

I Explore auto-scaling

I

...more details in the handouts.

I

You have the first week to try EC2 dashboard, Boto, AWSCli

and make the design of the experiments for Part B,C.

Deliverable Part A,B,C
