Start with the billing unit, not the headline price
A managed database price is rarely a single monthly figure. Across the listings here, entry prices span €0 to €876.09, so the question that matters is what that figure buys and how often you are charged for it.
SberCloud bills Evolution compute hourly under hourly, and charges per-minute for GPU capacity under per minute. Its entry plan, 1 vCPU, 1 GB RAM, 30 GB NVMe, is listed at RUB 23.75 hourly, while GPU capacity starts at RUB 240 an hour across models including B300, H100 and A100. That spread matters for short bursts and for long-running analytics jobs alike.
UCloud lists monthly billing with hourly granularity on its GPU line, so the same catalogue page can produce two very different totals depending on how long you keep a machine running. RisingWave prices from $0.23 and also offers a free tier, which makes it a sensible place to size a workload before committing to a paid plan.
Limits and quotas decide the bill you actually pay
The package that looks cheap gets expensive when quotas run out. UCloud's base allowance is 200 GB/month data package, 30 Mbps peak bandwidth, and usage past that is billed separately, so a database that replicates heavily can outweigh its compute line.
SberCloud includes 10 TB of outgoing traffic per month in its free tier, with outgoing traffic beyond that priced at RUB 1.15. Function work is charged by duration at RUB 0.0013 and by request volume at RUB 14.34, and 1,000,000 requests are included in the free allowance. Egress and request pricing are the two lines most often skipped in a comparison and the two most likely to change your total.
Control plane fees deserve their own line: SberCloud lists RUB 2.98 for the control plane, and its free tier does not include a free control plane. It does offer bonus credits, with a larger amount for legal entities and sole proprietors than for individuals. Storage is listed at RUB 814.68 a month, and the available storage types cover object storage with S3-compatible access.
Check the engine list before anything else
Engine support rules providers in or out faster than price does. UCloud's engine list is MySQL, PostgreSQL and MongoDB, so a team standardised on one of those has a short migration, while a team on a more specialised engine has to check the catalogue line by line.
SberCloud lists vps and bare metal as its server types, and its storage side is object storage with S3-compatible access, which keeps object-backed backups portable to other tooling. RisingWave is a newer name, founded in 2021, so the questions worth pressing there are about pricing granularity and support coverage rather than a long catalogue history.
Reliability, compliance and where the data sits
Uptime commitments are the easiest line to compare and the easiest to misread. SberCloud publishes an SLA of 99.9% uptime. Write that figure next to the availability your own product promises, because a lower number is a decision you take deliberately rather than one you discover later.
Compliance tells you what kind of assurance you are getting. SberCloud holds ISO/IEC 27001:2022, ISO/IEC 27701:2019 and ISO/IEC 27017:2015, and UCloud holds CMMI Level 5, ISO 9001 and ISO 27001. SberCloud's list also carries Uptime Institute Tier III Design, Facility and Operation entries, which speak to facility resilience rather than software assurance alone, so a regulated team should separate the two when reading either list.
Data residency can end a shortlist outright. SberCloud's headquarters is RU, it operates 9 locations, and its regions are listed as RU. If your data has to stay inside a particular jurisdiction, that row settles the question before any pricing discussion. SberCloud also provides DDoS protection, which matters for a publicly reachable database endpoint.
Support and the company behind the service
Support is a differentiator that gets ignored until something breaks. SberCloud offers email, phone and chat, a broad set that includes phone and chat, which suits teams that want a human on the line during an incident. RisingWave offers help centre and community, a narrower list, so a team without in-house operations capacity has to weigh that difference against the lower entry price.
Look at who you are actually depending on. The legal entity behind RisingWave is RisingWave Labs, while SberCloud operates as LLC Cloud Technologies. A named contracting entity, a clear support list and a published uptime figure together tell you more about reliability than any single feature comparison will.
A shortlist and an order to work through it in
Use the rankings for managed databases to build a candidate list, then read the individual reviews for SberCloud, UCloud and RisingWave in the same order every time: billing unit, quotas and egress, engine list, uptime commitment, then support.
Worked example: if your workload is steady and predictable, the hourly SberCloud plan at RUB 23.75 with 1 vCPU, 1 GB RAM, 30 GB NVMe and the storage rate of RUB 814.68 a month give you a number you can budget. If demand is spiky or experimental, the per-minute GPU billing under per minute and UCloud's hourly granularity on its GPU line both protect you from paying for idle capacity, while RisingWave's free tier lets you test a workload before any spend.
Honourable mentions for readers who want a wider field: Aiven and UpCloud are worth running through the same rows. Apply the same checklist to every provider you add: ask what the billing unit is, what the free allowance covers, what happens at the quota boundary, and what the uptime commitment is before the price.
