 ## **Spin up a Virtual Machine and run a workflow** <a name="vm"></a>
 Virtual machines (VMs) on AWS are called Amazon Elastic Compute Cloud (EC2) and are like virtual computers that you access via SSH and which start as (nearly) completely blank slates. You have complete control over the VM configuration beginning with the [operating system](https://docs.aws.amazon.com/systems-manager/latest/userguide/prereqs-operating-systems.html#prereqs-os-linux). You can choose a variety of Linux flavors, as well as macOS and Windows. Virtual Machines are organized into [machine families](https://aws.amazon.com/ec2/instance-types/?trk=36c6da98-7b20-48fa-8225-4784bced9843&sc_channel=ps&sc_campaign=acquisition&sc_medium=ACQ-P|PS-GO|Brand|Desktop|SU|Compute|EC2|US|EN|Text&s_kwcid=AL!4422!3!536392622533!e!!g!!ec2%20instance%20types&ef_id=CjwKCAjw7IeUBhBbEiwADhiEMedsuBikka4KyMJjZdw2Qi63FwjhvKhPlmHr9EYefV3GIE14lRz-ixoCqWIQAvD_BwE:G:s&s_kwcid=AL!4422!3!536392622533!e!!g!!ec2%20instance%20types) with different functions, such as General Purpose, Compute Optimized, Accelerated Computing etc. You can also select machines with graphics processing units (GPUs), which run very quickly for some use cases, but also can cost more than most of the CPU machines. Billing occurs on a per second basis, and larger and faster machine types cost more per second. This is why it is important to stop or delete machines when not in use to minimize costs, and consider always using an [idle shutdown script](/docs/auto-shutdown-instance.md).
 
-Many great resources exist on how to spin up, connect to, and work on a VM on AWS. The first place to direct you is the tutorial created by [NIH Common Data Fund](https://training.nih-cfde.org/en/latest/Cloud-Platforms/Introduction_to_Amazon_Web_Services/introtoaws3/). This tutorial expects that you will launch an instance and work with it interactively.
-[Here](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connect-to-linux-instance.html) is the Amazon documentation for different ways to connect to an EC2 instance. In NIH staff will be able to connect from their [local terminal via SSH](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connect-linux-inst-ssh.html) or in the browser via [Session Manager](https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager.html). If you are an NIH-affiliated researcher, you will only be able to use the Session Manager. We wrote a [guide with screen shots](/docs/connect_to_EC2.md) that walks through SSH options.
