1. First go to https://aws.amazon.com/ and click on "Sign In to the Console" on the top right corner. Login or create an account if you don't already have one.
2. After login, select "EC2" from the service dropdown menu.
3. Scroll down and select "launch instance".
4. Scroll down and select "Ubuntu Server 18.04" in step 1, and select the appropriate CPU size that is suitable for your simulation in step 2.
For exploring the functionalities of the website, we recommend the instance type of "t2.micro", which contains 1 CPU core and is free-tier eligible.
To reduce the runtime of simulations and optimizations of large meshes, we recommend the instance type of "t3.xlarge" or "t3.2xlarge", which contain 4 CPU cores and 8 CPU cores respectively.
For even shorter turnaround time, we recommend the instance type of "g4dn.xlarge" for hardware acceleration, which contains one Nvidia Tesla T4 GPU.
More information regarding instance types and pricing can be found on https://aws.amazon.com/ec2/pricing/on-demand/.
5. Skip Step 3 and selete the appropriate storage size that is suitable for your simulation in Step 4. We recommend at least 24 GiB of storage size.
6. Launch the instance on the bottom right corner. Before launching, Amazon Web Services will ask you to create a private Key file, which is used to access your instance. This is the "Pemfile" that you will be uploading when running the simulation. Please carefully save it somewhere as you will not be able to download the file again.
7. After the instance is launched, go the running instances, and click on "connect". Take a note on the Public DNS name, this is the "DNS" field that you will be typing in when running the simulation.
8. Go back to the running instance and click on "Security". Under this tab, click on the security group.
9. Under "Inbound rules", keep the SSH entry as default and add two new rules:
a. Type: HTTP; Port range: 80; Source: 0.0.0.0/0
b. Type: Custom TCP; Port range: a number between 8000 and 8999; Source: 0.0.0.0/0
Take a note on the Custom TCP port range number, this is the "TCP Port" field that you will be typing in when running the simulation.
When you are done with the tutorial, continue to the simulator.
