This paper describes some use cases of deploying SAP with vShield App. vShield App provides microsegmentation / zoning of different landscapes which enables a secure SAP deployment. The configurations covered here are examples only, but provide a starting point from which to plan for a security architecture to cover a SAP installation on VMware in production and non-production environments.
Workload characterizations conducted against SAP show that CPU resources are required by vShield firewall virtual machines, the extent of which is dependent on the network traffic generated by the application. When there is a need for additional firewall capacity, administrators can add CPU or memory resources to the vShield App appliance. If the cluster is resource limited, administrators can add another host to the cluster along with the vShield App appliance and the hypervisor module.
Customer workloads will differ from those tested here which will result in different utilizations of the vShield App firewall appliance. Situations where systems are designed as two-tier instead of three-tier would reduce network traffic between virtual machines and lower firewall appliance utilization. For example, some SAP customers may deploy database and application instances in a single large virtual machine.
Categorizing applications into a container such as vApp greatly simplifies management of firewall policies with vShield App. Application and security administrators can respond rapidly to specific demands in a dynamic landscape, and while virtual machine templates enable quick deployment of systems, vShield App facilitates speedy security compliance.
