    Expected result Remote clickhouse-client authenticates; the default user remains local-only.

Validate

clickhouse-client -q 'SELECT 1'

First boot: Service enabled at build; ready in seconds.

Costs & quotas

Software is billed by the marketplace at the listed rate; infrastructure (VM, storage, egress) is billed by your cloud at its standard rates. The recommended size fits default service quotas in most accounts — if you scale out, review your cloud's quota console before launch.
