Launching AMIs

Overview

After locating the BrainEngine AMIs, launch them in a manner appropriate for your organization and environment. Consult with your administrator for specific questions about VPCs, availability zones, security groups, or other EC2 details.

The minimum connectivity required is a security group that allows you to access the instances via SSH (port 22). When prompted by the launch dialogs, configure the instance to use a valid SSH keyset for the default system user (ubuntu).

For combined instances, launch on an m4.xlarge instance or larger. In most cases, 50GB standard gp2 EBS is sufficient to start.

For single deployments, use the following configurations:

• Select an instance type of at least t3.medium and click Next.

• Ensure you select the VPC that also includes the databases / API’s you will want to connect to and click Next.

• Increase the storage size to 50 GB or higher and click Next.

• Optionally add some Tags (e.g. app = brainEngine ) and click Next. This makes it easier to find if you have a lot of instances.

• Set the network security groups for ports 8080, 443 and 22 with sources set to 0.0.0.0/0 and ::/0, and click

• Review and Launch. We need to open ports 8080 (http) and 443 (https) so you can connect to the server from a browser, as well as port 22 (ssh) so that you can ssh into the instance to configure it and run BrainEngine. By default on a vanilla EC2, BrainEngine will run on port 443.
