Use this Marketplace launch option to set up the following configurable environment on AWS: A virtual private cloud (VPC) that spans two Availability Zones and includes two public and two private subnets, for security and high availability. The number of subnets is configurable. An internet gateway to allow access to the internet. In the public subnets, managed NAT gateways to allow outbound Internet access for resources in the private subnets. In a public subnet, a bastion host to provide Secure Shell (SSH) access to the IBM Spectrum Scale cluster. The bastion host instance is managed by an Auto Scaling group of 1, ensuring there will always be one host available An AWS Identity and Access Management (IAM) instance role with fine-grained permissions for access to AWS services necessary for the deployment process. Appropriate security groups for each instance or function to restrict access to only necessary protocols and ports. The Quick Start opens only ports for SSH and the IBM Spectrum Scale Daemon. Amazon Elastic Compute Cloud (Amazon EC2) instances for each logical role in the IBM Spectrum Scale deployment, in Auto Scaling groups. These consist of IBM Network Shared Disk (NSD) storage server instances and IBM Spectrum Scale compute instances.
