MariaDB SkySQL delivers a fully managed, high‑performance MariaDB service that handles provisioning, scaling, backups, and security so developers can focus on building applications. It runs on major public cloud providers and offers automated failover, point‑in‑time recovery, and built‑in monitoring. The platform supports both transactional (OLTP) and analytical (OLAP) workloads, with options for serverless scaling and dedicated clusters. Integrated tools like Data Lake, Query Optimizer, and security features such as encryption‑at‑rest make it suitable for modern, data‑driven applications.
PlanetScale delivers a fully managed, serverless MySQL platform built on Vitess, offering developers instant scaling, automatic failover, and a developer‑friendly workflow. It eliminates the need for manual database ops, letting teams focus on building applications. The service provides branch‑based development, built‑in sharding, and global replication, making it ideal for high‑traffic web apps, SaaS products, and micro‑service architectures that require strong consistency and low latency.
