My view on such matters is that it's best to find a solution that has a fallback option, which usually is an open-source software. That is to say, if you choose a cloud service, it's preferable that it is built on some open-source software. This way, if the costs become uncontrollable in the end, you can still fall back to an open-source software. For instance, CelerData has built its cloud service on StarRocks, and it's said that many users have used it to replace Snowflake and Big Query. Of course, you could also opt for Elasticsearch's cloud service, and if problems arise, you can replace it with OpenSearch.
