Key Takeaways
- Public Preview is live on AWS (Oregon, Tokyo, Singapore, Sydney) and Alibaba Cloud (Singapore).
- Dedicated isolation with elastic RCU scaling, removing the trade-off between predictability and cost.
- Built for mission-critical workloads like multi-tenant SaaS, Web3, and high-scale production apps.
- Pricing starts at $1,800 / month for ~5,000 RCUs, with storage metered separately.
Cloud-native databases have made it easier to ship transactional applications. Managed services, automatic failover, and elastic storage are now table stakes. The harder problems show up later: When a multi-tenant SaaS app starts hitting tail-latency spikes during compaction, when a serverless tier saturates a noisy neighbor, or when a dedicated cluster sits at 30% utilization because the team sized it for peak.
These are the workloads where the existing trade-offs stop working. Serverless gives elasticity but limits isolation. Dedicated gives isolation but locks in fixed capacity. Most production teams running mission-critical SQL workloads end up paying for one and wishing they had the other.
Today, we are announcing the Public Preview of TiDB Cloud Premium, a tier built specifically for production workloads that need both: Dedicated-grade isolation with serverless-style elasticity, on a resource-based consumption model.
What Is TiDB Cloud Premium?
TiDB Cloud Premium is a fully managed deployment tier of TiDB that supports mission-critical production workloads requiring strong performance isolation, elastic compute scaling, and enterprise security. It runs each customer on dedicated compute and network resources, scales independently of storage through Resource Compute Units (RCUs), and bills based on consumption rather than provisioned capacity.
In short: It is the deployment option for teams who need predictable performance and full data sovereignty without paying for headroom they do not use.
Why We Built Premium
The TiDB Cloud lineup already covers a wide range of use cases. TiDB Cloud Essential gives developers a serverless-style experience with elasticity and a low entry price, but resources are shared across tenants. TiDB Cloud Dedicated gives full isolation and the broadest control surface, but capacity is provisioned, which means teams either over-provision for peak traffic or scramble during spikes.
Premium fills the gap in the middle. Compared to Essential, it delivers stronger isolation at both the compute and network layers, so other tenants’ activity does not affect a tenant’s transactional latency. Compared to Dedicated, it removes the cost of idle headroom by scaling compute on demand. The trade-off teams have been making between elasticity, predictability, and cost is the gap Premium closes.
What You Get with TiDB Cloud Premium
TiDB Cloud Premium handles production environments where downtime, tail latency, and data sovereignty all matter at the same time. The tier ships with three core capabilities.
1. Predictable Performance with Instant Elasticity
In most distributed SQL systems, transactional queries compete with background processes like compaction, garbage collection, and data reorganization. Under sustained load, that contention shows up as p99 latency spikes that are hard to debug and harder to budget for.
TiDB Cloud Premium addresses this directly with:
- Horizontal scalability without sharding. Workloads grow from gigabytes to petabytes without application-level partitioning logic.
- Task-level isolation between foreground and background work. Compaction and analytical scans do not steal CPU from OLTP queries.
- Stable latency during maintenance. Failover, scaling, and version upgrades happen without throughput dips visible to the application.
2. Built-in Data Movement and Enterprise Security
Production systems do not sit in isolation. They feed analytics platforms, sync to data lakes, and migrate from upstream MySQL deployments. Treating data movement and security as add-ons creates integration debt that compounds.
TiDB Cloud Premium includes these as native capabilities:
- Native TiCDC for change data capture. Stream row-level changes to Kafka, Pulsar, object storage, or downstream databases.
- Integrated Data Migration. Move from MySQL-compatible sources with DM, or run high-throughput bulk imports from S3, GCS, or Azure Blob Storage.
- Customer-Managed Encryption Keys (CMEK). Bring your own keys via cloud KMS for full control of encryption at rest.
- Private networking and fine-grained access control. VPC peering, private endpoints, and role-based access for compliance-heavy environments.
3. Elastic Scaling Without Operational Overhead
Scaling a distributed database should not require a runbook. With TiDB Cloud Premium, throughput scales by adjusting RCUs in the console or via API. There is no replica management, no manual rebalancing, and no topology planning.
- Compute scales independently from storage.
- We meter storage separately and bill it on demand.
- High availability spans three Availability Zones by default.
Who TiDB Cloud Premium Is For
TiDB Cloud Premium serves teams whose workloads have outgrown developer-tier limits and whose business cases cannot tolerate the unpredictability of shared infrastructure. Three patterns we see most often:
- Multi-tenant SaaS applications. Per-tenant isolation, predictable throughput, and full audit logging for compliance frameworks like SOC 2, ISO 27001, and HIPAA.
- Web3 and event-driven services. High-frequency transactional writes paired with streaming pipelines via TiCDC and high-speed bulk imports.
- Production workloads at scale. Applications that started on a serverless tier, hit isolation or throughput limits, and need to graduate without re-platforming.
If you are running a workload like one of these on Amazon Aurora, Postgres, or MySQL today and starting to see scaling friction, Premium is worth a direct comparison.
Regional Availability
TiDB Cloud Premium is available in Public Preview today on:
- AWS: Oregon (us-west-2), Tokyo (ap-northeast-1), Singapore (ap-southeast-1), Sydney (ap-southeast-2).

How to Get Started with TiDB Cloud Premium
Three steps to spin up a Premium instance:
- Create the instance. In the TiDB Cloud console, select Premium, choose your cloud and region, set an initial RCU baseline, and configure public or private connectivity.
- Migrate your data. Use bulk import from object storage for large datasets, or the built-in Data Migration flow for live MySQL-compatible sources.
- Right-size your capacity. Start with the default RCU profile, run representative workloads, and watch in-app metrics for request rate and latency. Adjust RCUs up or down in real time.
TiDB Cloud Premium Pricing
Premium uses a resource-based pricing model built around Resource Compute Units (RCUs).
- Entry point: Starts at $1,800 / month for approximately 5,000 RCUs.
- Public Preview discount: 50% lower minimum baseline than the standard 10,000 RCU floor.
- Compute: Pay for the RCUs you provision, with instant scaling.
- Storage: Metered separately and billed on demand.

Rethinking Cloud Database Trade-offs
Most production teams have learned to live with three trade-offs: elasticity vs. predictability, simplicity vs. control, and performance vs. operational overhead. These trade-offs reflect how managed databases evolved a decade ago, not laws of physics.
TiDB Cloud Premium removes them. If your workload is starting to push the limits of conventional architectures, the Public Preview is a good time to see what changes when you stop choosing between isolation and elasticity.
