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.

摘要与快速解答

High-performance cloud servers with fast NVMe storage and dedicated RAM for database hosting.

架构设计与部署指南

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).

推荐硬件配置规格: 4 vCPU · 16 GiB RAM

成本优化策略

  • ✓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.

常见问题解答

关于云计算定价和基础设施配置的常见解答。

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.
