Overview of Bridge

What is a Bridge?

Bridge is an installable, lightweight independent agent that can be deployed on the customer’s local network. It is compatible both on Windows and Linux machines with 32 and 64-bit OS. 

Its role is to facilitate communication between Qntrl and external systems, such as on-premise databases, applications, or remote servers, ensuring a secure data exchange while maintaining a high level of control and security. The Bridge agent communicates with the Qntrl server through messages to obtain data. The extent of data access for each bridge can be entirely managed by the message request sent from the bridge. 

For managing expansive networks and high traffic loads, users can effectively deploy multiple instances of the Bridge. Additionally, it provides options for setting up alarms in the event of potential resource overuse, monitoring both real-time and historical performance, and facilitating smooth upgrades to the latest version.

The domain bridgews.qntrl.com:443 has to be whitelisted in the customer's network. 

Other grid users must use their respective domains, for example: EU grid users have to whitelist bridgews.qntrl.eu:443.      

Benefits of Bridge 

1. Connects customer's remote server with Qntrl
2. On-demand data processing
3. Provides secured gateway
4. Provides data protection by allowing only authorised access
   

Sample use cases 

Loan approval process                                    

Fintech services can validate sensitive information against their local database before processing loan applications.

In Qntrl, loan request forms can be added along with customer details, such as Social Security Number (SSN). This SSN is encrypted and sent to bridge, which then sends it to the local database to validate the customer's credit score, credit history, income details, and other details. After validation, the local database decides whether the loan can be processed, and sends a yes/no response to bridge, which then passes on the response to Qntrl. Based on the response, either the process is continued in Qntrl or terminated. In this process, there will be no unauthorized data retrieval or storage from the local database.

E-commerce order management                                         

E-commerce sites can use Bridge to manage orders and offer a secured gateway.    

​

A process for order management can be set up on Qntrl. Once an order is placed on the website, Qntrl checks the inventory for stocks, and then uses an API to request a payment link from the payment gateway server. Once the transaction has been completed, the payment gateway server uses Bridge to deliver a success message and transaction ID to Qntrl. The Qntrl workflow then continues to successfully deliver the customer's request. No private or unneeded data is collected or saved by Qntrl.

Retrieve Data from the local database                                    

Bridge can be used by any organization to interact with their systems on their local network.

Let's say an organization wants to retrieve a list of all their employees, complete with specific information from their MySql server, and display it in Qntrl. They can accomplish this by utilizing Bridge. The ability of the data to be processed is entirely dependent on how the administrator configures Bridge.

​

Device Monitoring and Failure Management via IoT

Bridge can be used to monitor data in an organization's IT workflow.

A process can be created in Circuit to monitor, troubleshoot, and re-calibrate IoT device parameters. IoT devices such as sensors, switches, and so on are typically installed in physical locations to monitor various parameters and then send the data back to a local storage server/disk. This data is also displayed locally on a dashboard to monitor various parameters. A Bridge can be installed on these storage servers/disks to monitor those data as a part of Circuit's flow to perform troubleshooting or re-calibrating parameters.
