Landscape data is pretty much at the center of all processes in cloud and lifecycle management and SLD and LMDB are the most important application in gathering landscape data you own:
A system landscape including consumers of landscape data with recommended SLD Data Suppliers setup
Since these processes evolve like the landscape itself, more landscape data is needed and hence processes to gather it need to evolve with it. Therefore, the recommendation is, to set all Data Suppliers instead of the RFC call to use the HTTPs protocol, which is now available for AS ABAP’s RZ70 transaction.
Why to Switch?
There are several reasons to bring RZ70 to HTTP(S):
Function: HTTP(S) based Data Supplier connections already provide additional information, for example on installed SAP notes
Guaranteed Future: HTTP(S) is the Data Supplier connection, where new features are made available
Harmonization: You are using one type of connection for all technical systems
