Cheapest Cloud Servers for PostgreSQL & MySQL Databases
Compare the cheapest cloud instances for running self-hosted PostgreSQL, MySQL, MariaDB, and SQLite databases with high disk I/O and RAM.
Executive Summary & Quick Answer
High-performance cloud servers with fast NVMe storage and dedicated RAM for database hosting.
Architecture & Deployment Guide
Databases require sufficient RAM to hold the active working set (indexes and hot table data) in memory cache (Postgres shared_buffers) and low-latency NVMe SSD storage for write-ahead logging (WAL).
Cost Optimization Strategies
- ✓Self-hosting PostgreSQL on a cloud VPS with NVMe storage saves 60-80% compared to managed database services (like AWS RDS).
- ✓Allocate at least 25% of system RAM to database cache pools for optimal query speeds.
- ✓Automate offsite backups to S3-compatible object storage for disaster recovery.

Frequently Asked Questions
Direct answers to common cloud compute pricing and infrastructure questions.
Is it safe to self-host PostgreSQL on a cloud VPS instead of AWS RDS? ▼
Yes, self-hosting PostgreSQL on a reliable cloud server with automated WAL backups (using tools like pgBackRest or Wal-G) provides enterprise-grade reliability while saving thousands of dollars annually on managed database markups.
