Gurobi now offers Gurobi Optimizer for the Amazon Elastic Computing Cloud (EC2) platform. With Gurobi Cloud, you can run the Gurobi Optimizer on as many machines as you like for as long as you like, without having to purchase new computers or new Gurobi licenses.  Usage is charged at an hourly rate, giving you significant new flexibility in the use of the Gurobi Optimizer.

Gurobi Cloud allows you to use the Gurobi Optimizer on 64-bit Linux machines. Amazon offers a variety of configurations, which have different capabilities and prices.

To use Gurobi Cloud, you'll need to perform several steps:

1. Create an Amazon Web Services (AWS) account. All access to Gurobi Cloud will be done through your Amazon AWS account.
2. 'Purchase' Gurobi.  There is no fee for this step; it simply adds Gurobi Cloud as an option on your AWS Management Console.
3. Each time you wish to use a Gurobi Cloud machine, you'll need to log in to the AWS Management Console to start an instance.  When your machine is ready, you connect to it through an 'ssh' client. When you are done with your session, you will need to return to the AWS Management Console and terminate your machine. You will be charged for the time from when you start the instance to when you terminate your machine.

You can find detailed descriptions of each of these steps in the Gurobi Cloud User Guide.

Detailed pricing information can be found in the Pricing section of the Gurobi client area, and the End User License Agreement can be found here.
