Create a COMSOL® License Server on EC2™
In this section you will learn how to use AWS CloudFormation™ to create a COMSOL
license server on EC2™.
In order to start a COMSOL instance on Amazon EC2™, you need a license server.
There are two possible ways to start a COMSOL license server in the cloud. One way
is to create a license server through which you access your on premise license server.
This approach requires you to forward ports from your on premise license server to
the cloud. Another way is to create a cloud-based license server, using its own
designated license file. This approach does not require you to forward ports to the
Amazon™ cloud, but requires a license file created for the cloud.
FORWARD YOUR ON PREMISE LICENSE SERVER TO EC2™
The steps below describe how to use the CloudFormation™ tool to create a
cloud-based license server through which you can access your on-premise license
server:
1 Go to https://console.aws.amazon.com/ and click the AWS CloudFormation™
icon.
2 Click Create New Stack.
3 Write a name for your stack, e.g. My-COMSOL-License-Server.
4 Choose to upload a template to Amazon S3™.
5 Navigate to the folder where you saved the AWS CloudFormation™ templates and
choose the file COMSOL_CloudLicenseServer.json.
