AWS Configurations

AWS ID Format

The AWS ID is transparent to Workload Manager. If AWS returns a longer instance ID, Workload Manager accepts this AWS ID as is. While the Java string does not have a length limit the database schema is limited to 255 characters.

Workload Manager AMI Details

If you need to share Workload Manager AMIs, contact CloudCenter Suite Support with the following information:

  • AWS account number

  • CloudCenter version

  • Contact email

  • Customer name

  • Customer ID (CID)

On-Demand Instance

With Multiple Volumes configured when deploying the application on AWS, users have the option to select pricing by using the On-Demand Instance.

Ephemeral Disks

When you configure 100 GB of disk space, you may only get 20GB VM. This is because Workload Manager only used the root disk size in earlier Workload Manager releases. You can attach one ephemeral disks if you configure a larger size in the instance type (see Map Images > Instance Types for additional context).

Root Volume Size

See Multiple Volumes and the Submit Job (v2) API for additional context.

Instance Profile

An optional Instance Profile field is available when you Setup Deployment Environments or set the Deployment Environment Defaults. If you configure this field, provide the Amazon Resource Name (ARN) used for the Instance Profile configured in your AWS Cloud account.

If you specify the Instance Profile name, Workload Manager launches VMs within the IAM role that is associated with the corresponding instance profile.

To successfully launch the AWS cloud account (either using as IAM role or the account secret key) you must have the required permission to pass the IAM role associated with the specified instance profile.

VPC

If the application VMs run in isolated networks (like Amazon's VPC), be sure to setup proper NAT rule (only outgoing needed) to allow application VMs to connect to RabbitMQ. 

The CCM instance that interacts with the CloudHSM server must reside inside the same VPC as the CCM. 

Refer to https://aws.amazon.com/articles/0639686206802544 for additional context.

Workload Manager ELB Representation

 AWS allows either internal or internet facing ELBs and they are associated to subnets that the instances will be on. Workload Manager uses this information by allowing you to select internal or external within each ELB tier of the Workload Manager application profile. From there, the subnet for the ELB is determined by where the application tier instances are instantiated.

Refer to the Amazon Documentation for additional context.
