# Learn About Cluster Architecture

This diagram illustrates the cluster architecture created by the template. When you use the [AWS CloudFormation templates](https://aws.amazon.com/cloudformation/) in this repository, it creates the [MATLAB Job Scheduler](#what-is-matlab-job-scheduler) and the following resources. For more information about each resource, see [AWS CloudFormation template reference.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-reference.html)

If you enable autoscaling, the [desired capacity](https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-capacity-limits.html) of the AWS Auto Scaling group is regulated by the number of workers needed by the cluster. The number of Amazon EC2 instances is initially set at `Number of worker nodes`. This number fluctuates between the `Minimum` and `Maximum number of worker nodes`. To change these limits after you create the stack, use the AWS Management Console. To change the amount of time idle nodes are preserved, adjust the value of the tag `mwWorkerIdleTimeoutMinutes`.

1. **Copy AMI into your account**: Use this AWS quick-create link to copy the latest MATLAB Parallel Server AMI on Windows into your AWS account. Clicking the link opens a CloudFormation template with prepopulated fields. Set the AWS region in the AWS console to your desired region and deploy the template to copy the AMI. Copying takes 5 to 15 minutes. You are responsible for the costs associated with the storage of this AMI and its snapshots in your AWS account. To save costs, delete this AMI and the snapshots if you no longer need it.

2. **Deploy a cluster using your copied AMI**: After your copy is complete and your AMI is ready, use the `LaunchClusterWithCopiedAmi` link in the outputs tab to deploy a cluster in your desired region. You can also share this link or the Custom AMI ID with others in your AWS account to allow them to deploy clusters using the same AMI.
