Cloudwatch is a general monitoring and observability service from AWS that allows people to manage all the different cloud services AWS offers (you could compare it to an Element Management System from a vendor to manage their own products). Cloudwatch offers an API, through which you can get basic information about the cloud services that it manages. So the second driver that you reference here is to manage the MediaConnect service via Cloudwatch. The first driver you reference is the one that manages the MediaConnect service directly, i.e. it communicates directly with the API provided for the MediaConnect service. The difference? In general, the Cloudwatch version is more basic and probably serves you well if you are just looking for some monitoring of your MediaConnect services with DataMiner. The other driver that uses the MediaConnect API directly is going to offer you more granularity and control, and will be the one you need if you want to do more sophisticated things with DataMiner, such as automation and all that. I'm not an expert on the matter, so some people might be able to give you more details.
