Create new instance in default network
Chosse Ubuntu 16.04 LTS

This will create a proxy server in whatever your availability zone your VPC is in. For me, that's us-east-1b. For you, that may be something different. Steps 10+ should more or less work regardless of your provider since those steps cover the setup and configuration of TinyProxy.

Click the Launch Instance button.
Choose Ubuntu Server 14.04 LTS (HVM), SSD Volume Type. This isn't strictly necessary. If you choose another OS, check its documentation for how to install new packages.
On the Choose an Instance Type screen, select t2.micro. It's Free Tier eligible.
Click the Next: ... buttons until you reach the Configure Security Group screen.
- You may wish to reduce the amount of storage on the Add Storage screen. This is optional.
- You may wish to add a tag on the Tag Instance screen. This is also optional.
On the Configure Security Group screen:

Select Create a new security group.
