Security group acts as a virtual firewall for your Aurora database instances to control the incoming and outgoing traffic. Inbound rules control the incoming traffic to your instance, and outbound rules control the outgoing traffic from your instance. When you launch an instance, you can specify one or more security groups. If you don’t specify a security group, Aurora uses the default security group. You can add rules to each security group that allow traffic to or from its associated instances. You can modify the rules for a security group at any time. New and modified rules are automatically applied to all instances that are associated with the security group.
On the source mainframe environment, application data was stored on VSAM files. Micro Focus does supports VSAM files. However, VSAMs are the single point of failure. Hence, we are using Micro Focus Datastore feature to store application data on Aurora PostgreSQL database.
