Clickhouse now has a hosted version as well also there is the altinity clickhouse operator to install it on your own k8s cluster
I couldn't tell if you meant ClickHouse the company or ClickHouse the database in your comment. If the latter there are multiple hosted ClickHouse services--by my count at least 12 though not all are available in every market. This seems like a good thing for users.
p.s., We found out a while back that one of the ClickHouse services in China runs on the Altinity Operator. We occasionally get issues/PRs from them, which is kind of cool.
Disclaimer: I work for Altinity.
I feel that databases/warehouse solutions being available through the k8s operator framework is fantastic, especially if it makes sense for your business to package the solution as part of larger infrastructure offering. It is a little bit of a learning curve though.
FYI - ClickHouse Cloud is now available for self-service in ap-south-1 (Mumbai).
