Analysis AWS

For Workshop members without access to computing resources - Preconfigured Amazon Web Services servers can be used

Accessing compute resources on AWS:

Speak with Jeff Stout to get the current IP address and PEM key
${PATH} is the path to the PEM key provided to you

 ssh -X -i ${PATH}/AWS.pem ubuntu@IP_ADDRESS_PROVIDED

Jupyter Notebook Over a Remote Connection

1) Run one terminal to start the notebook and forward the outputs to local web browser:

 ssh -i AWS.pem -L 8887:localhost:8887  ubuntu@IP_ADDRESS
 conda activate workshop  
 jupyter notebook --no-browser --port=8887

2) Copy the output of the notebook (see example below) and enter into your laptop web browser (Firefox, Chrome, etc.). Do not click on the link - it will try to launch on the AWS computer

Installed software

1. Server Config
   1. google > fedora aws > select the AMI number for N.Virginia
   2. In AWS > launch instance > search for AMI number > (Under community) > Launch
      1. https://alt.fedoraproject.org/cloud/
2. Determine an image (search for fedora in community)
3. Create a keypair and download the key
   1. The download will be in the form of a .pem file
   2. We will need to distribute this key to the users
4. Launch the instance
5. Log into the instance using ssh
