"Powered by Aiven" + nearly identical interface, so this is kind of a reselling arrangement? Aiven supports timescale on postgres, so what additional features does Timescale Cloud provide?
Aiven Postgres supports the open-source version of TimescaleDB.
But Timescale Cloud is the only hosted service where you can get the full TimescaleDB experience, which includes our community and enterprise features (eg interpolation, data retention policies, continuous aggregates, data reordering, etc). [1]
It also includes special machines types and plans more suited for time-series data that we co-developed with Aiven.
It is also the only hosted service directly staffed by the TimescaleDB development team.
One main difference in these sorts of arrangements is vertically-integrated support.
If your Aiven database is having Timescale architecture problems, your support contact is someone working for Aiven who would need to turn around and reach out to Timescale about the bug (or suggest that you do so.)
If your Timescale Cloud database is having Timescale architecture problems, your support contact is someone working at Timescale who can just call over the guy who wrote the code with the bug in it.
(On the other hand, if your problem is with the Aiven backing cluster, it'll presumbly take slightly longer for Timescale Cloud to resolve, given that they'd have to bounce that forward.)
In this case we (Timescale) are your main line of support. Our job is for you to have a 100% positive experience on Timescale Cloud. The buck, as it were, stops with us.
