Microservices and on-premise clients

On-premise clients access the same D2L microservices in AWS as hosted clients, but they access them through their on-premise Brightspace instances. D2L microservices in AWS do not require any installation. D2L microservices in AWS cannot be hosted in on-premise environments.

To access certain features in Brightspace platform 10.6, on-premise clients must agree to permit access to centrally hosted microservices. For example, the Landlord Service and Authentication Service are required for accessing Brightspace Insights and Brightspace Pulse. Specifics on how to do this depend on how each client's environment is configured. For example, a client may have specific firewall restrictions that their IT department must adjust to permit traffic to D2L microservices in AWS.

Health checks that report on the availability of D2L microservices in AWS are monitored by D2L and are not available to on-premise clients.

Microservices and data

Depending on its function, transmission and storage of data is a consideration for microservices. The location of each data store is based on many factors, including the location of the microservice itself, security of the data, availability of the data, and dependencies on other microservices. D2L works with customers in many regions, jurisdictions, and markets with different needs and requirements around data privacy. We provide information on the data that is transmitted and stored for each microservice, allowing organizations to review it as needed.

Microservices architecture

The following architecture diagram displays current D2L microservices, their deployment locations in the Brightspace Cloud, and the dependencies among them with new Brightspace products and other microservices. For detailed information, refer to the sections for individual microservices in this guide.
