Middleware for DDE

The Disadvantages of a Middleware Integration like Braxos Steward for Destination Dispatch Elevator

Slower card reads and response from destination dispatch and access control system - poor user experience
Vendor who integrates with Middleware has no control of the integration
Another point of failure with another vendor
More on-premise software to maintain, upgrade and protect from cyber attacks
More finger pointing when there is an issue
No real-time visualization of Access Control and DDE Messaging to determine issues and who is responsible
Often threatens the real-time performance of a system
Does not integrate with all DDE features
No ability to use a smartphone to call an elevator and receive a car assignment
Lack of real-time Visitor Management/Access Control integration
No ability to remotely diagnose problems
Too many platforms to be covered
