Cloud Computing Lab

This the final code of our lab.

• Cloud Convert Final Version

  This is the codes of clients, nodes and resource managers.

• Create

  Codes using AWS JDK to create or terminate instance.

• python draw

  Codes used to draw experiment figures.

Method of Calling checkME.jar

• The checkME.jar file is delete to prevent others access to the instance.
• JDK 1.8 required.

---

• List all running instances and their information, write it in the cvs file (no input)

java -jar checkME.jar

- This will list information of all running instances. And put al information in a cvs file named `runningInstance.csv`, which is under the **same path** of the jar file.

- The cvs file will be update every time.

- Attention: as shown in **runningInstance.csv**, the order of the attribute is `publicDNS`, `publicIP`, `privateIP` and `instanceId`.

Output:

<CurrentPath>/runningInstance.csv

---

• List all instances and their information (two inputs)

  java -jar checkME.jar list all

  This is useless, just checking the instance, including stopped, running, terminated instances that you can see in the dashboard. It will printout every instance with some information.

---

• Start a new instance with default AMI(currently ami-5579bc3a) (One input)

  java -jar checkME.jar AddSure

  • This will create an instance based on one AMI. And put it's information in a cvs file named createInstance.csv, which is under the same path of the jar file.

  • If cvs does not exist, it will create the cvs file and put it in the first line.

  • If the cvs file does exist, it will add the information in the last line.

  • How to read the IP and other information from cvs file is already implemented int the code, please refer to readCSV() in EC2_Wrapper.java under Create/src directory.

  • Attention: as shown in createInstance.csv, the order of the attribute is publicDNS, publicIP, privateIP and instanceId.

  After 30 seconds,

  output:

  Creating instance...

  this.instanceId = i-094cb3a22d2c13803

  this.publicDNS = ec2-35-156-16-234.eu-central-1.compute.amazonaws.com

  this.privateIP = 172.31.20.218

  this.pubpublicIP = 35.156.16.234

  <CurrentPath>/createInstance.csv

  You have 11 Amazon EC2 instance(s).

• Start a new instance with user defined AMI (Two input)

  *java -jar checkME.jar AddSure <amiID>

  ie: java -jar checkME.jar AddSure ami-da7cb9b5

  Output: Creating one instance with AMI= ami-da7cb9b5...

  Other behaviour is the same as the default AddSure

---

• Check the status of one instance (Two inputs)

  java -jar checkME.jar list <ID>

  ie: java -jar checkME.jar list i-0f73e92cb135f557b

  • If the instance is running,

    output: running

  • If the instance is terminated or stop, after 5 seconds,

    output: Error: instance ID may be wrong or instance is not running...

---

• Terminate the instance (Two inputs)

  java -jar checkME.jar delete <ID>

  ie: java -jar checkME.jar delete i-0130f2bd929431aee

  If terminate successfully

  output: Terminate i-0130f2bd929431aee successfully.
