Side note on Confluent’s products. Thanks for that link - the “Disaggregation of Revenue” table where the 73% and 61% numbers came from shows that Confluent Cloud revenue increased from $94M in 2021 to $211M in 2022, which was more than Confluent Platform’s revenue growth. If those growth rates continue then Confluent Cloud will very soon be the majority of their revenue.
I always take those numbers with a big pinch of salt. There is a wave, in the management world, that wants every business to be "Cloud” (i.e. SaaS), because of the (largely correct) assumption that it enables better rent-seeking and long-term lock-in. So every vendor is officially busy "pivoting to a subscription model" and wants to show growth in that area to investors, so they file everything they can under "cloud" divisions.
