Add MongoDB Atlas private endpoint compatibility inside MAS Core

Hello IBM Team,

Today, MongoDB Atlas is compatible with MAS for Core and SLS Service

As per this document : https://www.ibm.com/docs/fr/mas-cd/continuous-delivery?topic=overview-mongodb

But it seems that the MAS application is only compatible with using the hosts of MongoDB mongodb:// protocol), normally there is 3 hosts, 1 primary and 2 secondary

This method is used for self-hosted MongoDB clusters

In the case of MongoDB Atlas, they give us a feature that is called "Private Endpoint"

We can link the private endpoint to Cloud provider like AWS, Azure or OCP to allow to have a load balancing and an unique entry for the whole traffic

This system is using the protocol "mongodb+srv://" as per the MongoDb Atlas documentation here : https://www.mongodb.com/resources/products/fundamentals/mongodb-connection-string

But today the MAS stack is not compatible with this system, as per the pods that i checked on MAS Core / SLS, when checks are done, they are capable to use mongodb:// protocol only

For our use case to use MongoDB Atlas Saas, this is occuring a lot of problem

• The single endpoint cannot be used

• We are losing the load balancing effect, if the primary node change, the configuration is broken

• In case of upgrade of the MongoDB version, the hosts can change they name and the whole Cores that will be tethered on the SLS Service will need reconfiguration too

• Using the hosts can also occurs latency, because the endpoint is linked between Cloud provider/MongoBD Atlas that use a backbone between them to be more quick and i'm not sure that he is used when using the hosts directly

We would like to add this private endpoint compatiblity to the MAS stack, this could useful for other customers that want to use MongoDB Atlas service

Could you please consider it ?

Thanks in advance

Have a nice day
