Subscribe to LIT for Traders via our AWS Marketplace landing page

Manage your subscription to LIT from the AWS Marketplace home page

Click on ‘Manage subscriptions’

Click on Launch new instance

Leave the default values. Click ‘Continue to launch through EC2’

Choose the name of this instance:

Leave the default value for the AMI:

Choose your desired instance type:

Select (or create) one of your own key pairs:

This is important. If you do not already have a key pair, you must make one by clicking on the ‘Create new key pair’ link:

Give it a name, any name. Click ‘Create key pair’ – when prompted, save the file(s) to a secure location and ensure that the data is backed up. This is how you will gain access to the machine’s command line once the machine has been initialized.

Next, Choose your network configuration. Follow your own organization's policies and best practices. Let your IT person know you need ports 80, 8080, and 22 open at a minimum. By default, a security group will be created for you in AWS which has ONLY the ports required to start the application– but you are welcome to create your own to even further restrict access.

Choose your storage configuration:

The current default values assume that you’ll do all of your work on one drive. In future versions we will recommend separating the application and data drives into two separate volumes. If you wish to do so now to comply with future versions, add a data volume now with a size of your choosing.

Click ‘Launch instance’. The instance will be created …

This steps happens very quickly.

Verify that your security group settings allow inbound traffic on ports 80, 8080, and 22:

Click on the instance ID link

First-time Initialization#

Click on the instance ID again.

Click on the Public IPv4 address “open address” link. If you have not set up SSL in some previous step your browser will land on a broken page like this:

Click on the url bar at the top of the screen and press the arrow keys to show the full url including the protocol:

And change the “https” to “http”.

If your network administrator set up SSL, this step isn’t necessary.

If you’ve given your instance enough time to warm up (2-3 minutes) then you will land on this page:

Select the protocol (ask your IT administrator)
Select which network interface to bind to (usually the public IP address; not one start with “127” or “172”, usually last in the list)
Leave the SSH port as the default value unless your IT administrator tells you otherwise
Copy your machine ID and give it to your LIT Sales representative or LIT Customer Success advocate
They will provide you with the values to use for “Licensee” and “License”

Anytime your machine’s IP address changes the LIT platform will detect the change and ask you to choose a new IP address to bind to.

Click the Assign button. LIT will now bind itself to your machine … This step typically takes less than 5 minutes. It depends on the speed of the machine.

You are directed to the login page. You'll be provided a temporary username/password. You'll be prompted to create a new secure password. Follow your IT administrator’s best practices:

You will now be prompted to enter that password to establish a trust relationship to the machine.

You are taken to this landing page. The platform is now fully installed.
