Guidelines for deploying Secure SD-WAN in the Engine/VPN role
There are some general deployment guidelines for Engines, Master Engines, and the SMC.
| Component | General Guidelines | 
|---|---|
| Management Server | Position on a central site where it is physically accessible to the administrators responsible for maintaining its operation. | 
| Log Servers | Place the Log Servers centrally and locally on sites as needed based on log data volume and administrative responsibilities. | 
| Management Clients | Management Clients can be used from any location that has network access to the Management Server and the Log Servers. | 
| Management Server | Position on a central site where it is physically accessible to the administrators responsible for maintaining its operation. | 
| Engines | Position Engines at each location so that all networks are covered. Engines can be clustered. Functionally, the Engine Cluster is equal to a single high-performance Engine. Cluster deployment sets up a heartbeat link between the Engines. The heartbeat link allows the devices to:

| Master Engines | Position Master Engines where Virtual Engines are needed. For example, at a hosting location for MSSP services or between networks that require strict isolation. Master Engines
                                                                                        can be clustered. A clustered Master Engine provides scalability and high availability. In a Master Engine
