FlashGrid Cluster can be deployed on EC2 Bare Metal instances of all supported instance types. However, due to current limitations in the CloudFormation functionality, the initial deployment has to be done on VM instances.
To deploy FlashGrid Cluster on EC2 Bare Metal instances:
1) In FlashGrid Launcher, select a VM instance type for the database nodes. The largest VM instance size is recommended to match the memory size of the bare metal instance. For example, select r5b.24xlarge instead of r5b.metal.
2) After cluster deployment is complete, follow instructions to resize database nodes to the desired bare metal instance type.
Note: If you are not able to start the instance after resizing it because of insufficient capacity, then making upfront capacity reservation is recommended.
