1 Network Virtualization and Data Center Networks Qin Yin Fall Semester / 18

2 News We have a discussion list: virnet@lists.inf.ethz.ch 2 / 18

3 Assignment 2 - Cloud computing Goals Gain experience using EC2 services Deploy an application over the IaaS Try auto-scaling mechanisms - Boto library and AWSCli interface Benchmarking on the EC2 Infrastructure Compare costs between Cloud and In-house solution 3 / 18

4 Structure of the homework Get credentials to log-in to the cloud Part A - 1st week - Boto + EC2 playing + proposal Part B - 2nd week - Benchmarking Part C - 3rd week - Auto-scaling End ABC - deliver report A2ABC Part D - 4th week - Auto-evaluation + Billing Final submit 4 / 18

5 Get credentials and how to use them Get credentials: Hw folder: systems/virnet13_students/trunk/name/a2abc Under your A2ABC, you should find the file credentials containing: user name,access key id,secret access key,password How to use them: Amazon dashboard: Login to Amazon EC2 using: username, password URL : AWSCli and Boto APIs username, access key id, secret access key... Explained later in the slides 5 / 18

6 Part A - 1st week AWSCli + Boto EC2 dashboard Submit proposal: Next week consultation (29th Oct) Or by before (28th Oct - 11:59AM) The proposal should cover the important details of how you intend to proceed with Parts B and C, in particular: Benchmarks: questions you seek to answer and your hypotheses. Planned modifications to your overlay network. Auto-scaling: describe your strategy, for example, when and how is it triggered? 6 / 18

7 Environment setup Install anaconda python: download it free and install it Advantages: use boto-python library, ipython, pip 7 / 18

8 Configure AWSCli URL: To install: pip install awscli (you installed pip following previous slide) 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 For the meaning of access key id and secret access key see slide above Get credentials and how to use them 8 / 18

9 Test AWSCli connection Create KeyPair file mykeypair.pem : aws ec2 create-key-pair --key-name mykey > /mykey.pem Result: In the EC2 dashboard - Key Pairs page you will see the pair with the name you just created: us-west-2#keypairs: 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. 9 / 18

10 Configure Python boto URL: - Check EC2 and Auto-Scaling links You should already have it installed Otherwise: pip install boto 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 For the meaning of access key id and secret access key see slide above Get credentials and how to use them 10 / 18

11 Test Boto Cli connection 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 ) By running this script you launch a new instance. Check EC2 dashboard - Instances to see the process in execution. 11 / 18

12 Test Boto Cli connection (cont.) In the code from previous slide: amid03ea1e0, stands for Amazon Machine Images, further reference - To get the code of such an image go to the Launch button of each image. mykeypair, the key we have created with AWSCli t1.micro, type of instance, further reference - amazon.com/ec2/instance-types/#instance-details 12 / 18

13 EC2 dashboard - Remember Management access rights to your colleagues instances. $ 100 recommended for each students Eg. run 15 large instances for one day each, or 6 micro instances continually for a month. 13 / 18

14 Part B,C - 2nd and 3rd week Main objectives: Explore benchmarking Overlay Network Integration Explore auto-scaling...more details in the handouts. You have the first week to try EC2 dashboard, Boto, AWSCli and make the design of the experiments for Part B,C. 14 / 18

15 Deliverable Part A,B,C Due date - Monday 11:59am Nov. 11, 2013 Submit under.../trunk/name/a2abc/report.pdf 15 / 18

16 Part D - 4th week Main objectives: Auto-evaluation : Due date - Monday 11:59am Nov. 18, 2013 Submit under.../trunk/name/a2abc/review/review.txt Billing - more details in handouts Review Part B,C with results from auto-evaluation, Add billing and submit final report. Final Report : Due date - Friday 11:59am Nov. 22, 2013 Submit under.../trunk/name/a2d/finalreport.pdf 16 / 18

17 Summary 4 due times: A2A Proposal due: Monday 11:59am, Oct. 28, 2013 A2ABC report due: Monday 11:59am, Nov. 11, 2013 A2D Auto-Evaluation due: Monday 11:59 am, Nov. 18, 2013 A2 Final Report due: Friday 11:59 am, Nov. 22, 2013 PartA,B,C,D: 20 points ( ) 17 / 18
