Overview
ClickHouse
ClickHouse is a high-performance, column-oriented database designed for real-time analytical processing. You can process billions of rows and tens of gigabytes of data per second, making it ideal for applications that require instant results from massive datasets. Instead of waiting minutes for complex reports, you get answers in milliseconds using familiar SQL syntax.
You can deploy it as a self-managed open-source solution or use ClickHouse Cloud for a fully managed experience that scales automatically. It solves the problem of slow query speeds in traditional databases by using columnar storage and parallel processing. Whether you are building observability dashboards, ad-tech platforms, or financial monitoring tools, you can handle high-velocity data ingestion and complex analytical queries without managing complex infrastructure.
Percona
Percona provides you with enterprise-class distributions of popular open source databases like MySQL, PostgreSQL, and MongoDB. You can run these high-performance versions in your own data center or the cloud without the restrictive licensing costs of proprietary vendors. The platform focuses on giving you full control over your data while ensuring your systems remain highly available and secure through hardened builds and expert-tested configurations.
You can also use their specialized monitoring and management tools to gain deep visibility into your database performance. Whether you are a database administrator at a scaling startup or a DevOps engineer at a global enterprise, these tools help you identify bottlenecks and automate backups. It solves the common problem of vendor lock-in by keeping your infrastructure strictly open source while providing the 24/7 support you need for production environments.
