Overview
Description

TiDB is an open‑source, distributed NewSQL database that delivers horizontal scalability and strong consistency while speaking the MySQL protocol. It is designed for cloud‑native environments, allowing developers and DevOps teams to run transactional and analytical workloads on a single platform. Built on a shared‑nothing architecture, TiDB integrates tightly with Kubernetes and Prometheus, providing real‑time monitoring and automated failover for mission‑critical applications.

YugabyteDB is an open-source distributed SQL database built on PostgreSQL, designed to give applications horizontal scalability and high availability without giving up relational features and PostgreSQL compatibility. It automatically shards and replicates data across nodes, supports multi-master writes, and includes built-in disaster recovery for global, always-on deployments. The database can be run self-hosted or consumed as YugabyteDB Aeon, a managed database-as-a-service available on AWS, Google Cloud, and Microsoft Azure. Recent additions include vector indexing for AI and RAG workloads alongside enterprise features for security, observability, and connection management, aimed at teams modernizing legacy systems or building multi-region cloud-native applications.
