Fully managed ClickHouse® for real-time analytics at any scale

ClickHouse® is an open-source, column-oriented database (OLAP) built for real-time analytics on large datasets. Managed ClickHouse® on Exoscale is ClickHouse as a service, a fully managed offering where Exoscale handles provisioning, scaling, patching, backups and monitoring, so you can query data without operating the infrastructure yourself.

Yes. Exoscale offers fully hosted ClickHouse® as a managed service. With this ClickHouse managed service, Exoscale runs, scales, patches and backs up the cluster for you, so you get production-grade ClickHouse hosting in GDPR-compliant European zones without managing any servers yourself.

ClickHouse® excels at real-time analytics, observability (logs, metrics and traces), real-time reporting and data warehousing, and analytical backends for AI/ML workloads. It is designed to aggregate billions of rows in milliseconds, which makes it ideal for user-facing dashboards and high-volume event analytics.

ClickHouse pricing on Exoscale is billed per second based on the selected plan, with no upfront commitment and no minimum term. Pricing is all-inclusive. There are no hidden fees and no egress surprises. See our pricing page or use the pricing calculator to estimate costs.

Yes. Managed ClickHouse® on Exoscale is a fully European, GDPR-compliant alternative to ClickHouse Cloud and US hyperscalers. Your data is stored in ISO 27001-certified European data centers and never leaves the country of your chosen zone, with transparent per-second billing and no vendor lock-in. If you are evaluating a European ClickHouse alternative, you get the same open-source engine without sending data outside the EU.

All Managed ClickHouse® clusters run in European data centers, and your data stays in the country of the zone you choose. Tiered storage keeps colder data in Exoscale Object Storage in that same zone, so hot or cold, it never leaves Exoscale infrastructure. That gives you full GDPR compliance and data residency, which matters for regulated industries such as finance, healthcare and the public sector.

Yes. ClickHouse® 25.8 includes generally available approximate nearest-neighbor search using the HNSW vector similarity index, with binary quantization to reduce memory usage. You can serve embedding workloads such as RAG pipelines, recommendations and semantic search directly from the engine that already stores your analytical data.

Tiered storage automatically moves data from fast local disk to affordable S3-compatible Exoscale Object Storage as local storage fills, and you can add per-table TTL policies for age-based rules. You keep recent data on high-performance storage for sub-second queries while reducing the cost of long-term retention, and you can still query the colder data directly.

Managed ClickHouse® is in early access. You create and manage services with the Exoscale API or the Exoscale CLI, following the quick-start guide. Portal integration arrives with general availability. Startup and Business plans are self-service; larger and Premium plans are enabled per organization on request.

Yes. Managed ClickHouse® reads from Managed PostgreSQL with the built-in PostgreSQL table engine, queries Object Storage directly with federated s3() queries, and connects to Managed Grafana for dashboards, so you can analyze your data where it lives under one managed platform.

Yes. Because Exoscale runs 100% standard, open-source ClickHouse® with no proprietary fork, your queries, schemas and tooling work unchanged. Migrate using native ClickHouse tools such as clickhouse-client and clickhouse-backup, or load data straight in through the built-in S3 and PostgreSQL federated queries. See Copy data across instances for a step-by-step guide.

Both are analytical databases, but ClickHouse® is open source and optimized for low-latency, high-concurrency queries that power real-time and user-facing applications, while Snowflake is a proprietary cloud data warehouse for broad SQL analytics. ClickHouse® is typically faster and more cost-efficient for high-concurrency, low-latency workloads, and on Exoscale it avoids vendor lock-in and keeps your data in Europe with predictable per-second pricing.

PostgreSQL (Postgres) is a row-oriented relational database ideal for transactional (OLTP) workloads, while ClickHouse® is column-oriented and built for analytical (OLAP) queries over huge datasets. Many teams use both: Managed PostgreSQL for application data and Managed ClickHouse® for real-time analytics, connecting the two through ClickHouse’s built-in PostgreSQL table engine.

Yes. Managed ClickHouse® offers high-availability configurations with replication and automated failover, backed by a 99.99% uptime SLA on Business and Premium plans. Combined with automated backups, this keeps your analytics available during node failures and maintenance, without any manual intervention.
