Hi Dojo,
Some clarifications needed, please.
I'm comparing the two possible configurations shown in this section of the documentation:
a) gRPC - using 443 between the DMAs
b) .Net remoting via 8004 
1) When upgrading to 10.3.0, can a DMS cluster still run without enabling the gRPC port?
2) Once 443 is open at FW level, is there any DMA configuration to be operated to switch to gRPC?
If so, where? Or would 10.3.0 require the gRPC automatically?
I read "recommended" - hence trying to understand what's viable in future.
Thanks
Hi Alberto,
.NET Remoting is still the default method of communication for all DataMiner versions which are currently supported. However, we recommend switching to gRPC when running DataMiner 10.3.6/10.3.0 or newer, because gRPC is more secure. gRPC will become the default method of communication in future versions (probably starting from the next main release).
If you would want to switch to using gRPC, I would recommend to have a look at the sections on secure client-server and server-server communication in the DataMiner hardening guide, since these will point you in the right direction on how to switch from .NET Remoting to gRPC.
Great, Seppe
that’s the kind of answer I was looking for 😉
So we’ll look into having the gRPC prerequisites specified in time for configuration with improved security.
Kinda hard to select the best answer now (^_^)
You guys are top guns!
Thank you!
