I'm not sure there is anything extra messy about MLOps: there are lots of vendors in pretty much any area that has profit potential. If you put all vendors on a chart, it will look messy, but you aren't going to be working with ALL of them (e.g., if you pick Snowflake you likely won't also be working with RedShift, Databricks...). The messy part I guess is the evaluation/selection, but not the integration or learning per se, as this article seems to imply. The article looks like a good reference for what's out there though.
