Every application needs a database, and you have two basic options: run it yourself on a VPS or dedicated server, or use a managed database service where the provider handles installation, backups, patching and failover. Both are valid. The right choice depends on your skills, budget, data size, and how much downtime you can tolerate.

What “managed” includes

Task Self-hosted on a VPS Managed service
Install and configure You Provider
OS and database patches You Provider (in maintenance windows)
Backups and point-in-time recovery You set up and test Built in
High availability / failover You build (replicas, Patroni, Sentinel…) Option or built in
Monitoring You set up Basic dashboards included
Tuning Full control Limited parameters
Extensions, plugins Anything Approved list only
Superuser access Yes No
Query and schema design You Still you

A managed database doesn’t fix slow queries or bad schemas. That part stays your job either way.

Cost

Managed databases cost noticeably more than the same CPU and RAM on a VPS: you pay for the automation, the redundancy, and the provider’s engineers. Storage, backups, extra replicas, and data transfer are often billed separately.

Self-hosting is cheaper in money, but costs time: setup, monitoring, upgrades, and the skills to recover when something breaks. For a small team without database experience, one bad incident can outweigh years of savings. For a team that already runs Linux servers, self-hosting a database is a well-understood task.

Performance

  • Self-hosted on the same VPS as the app: no network hop, which means the lowest latency. Good for small and medium apps.
  • Self-hosted on a separate VPS or dedicated server: dedicated resources and full tuning freedom (buffer pools, kernel settings, local SSD).
  • Managed: solid performance, but you’re limited to the provider’s instance types and parameters, and the app connects over the network, so it should be in the same region.

For large or I/O-heavy databases, a dedicated server with local SSDs often gives the best price/performance. See dedicated servers in the USA.

Control and portability

Self-hosting gives full control: any version, any extension (PostGIS, TimescaleDB, pgvector…), any configuration, superuser access, and data that lives on infrastructure you choose. Managed services restrict some of this, and moving away can take planning (exports, replication to the new host). See PostgreSQL extensions.

Reliability and backups

This is where managed services earn their price: automated backups with point-in-time recovery, standby replicas with automatic failover, and tested procedures.

Self-hosted, you can achieve the same, but you must build and test it:

Security

Managed services provide private networking, encryption at rest and TLS by default. Self-hosted, you configure these yourself: localhost or private binding, firewall allowlists, strong authentication, TLS, and encrypted backups. It’s not hard, but it must be done. See database security.

Decision guide

Situation Good fit
Small app, one server, tight budget Self-hosted on the same VPS
Team comfortable with Linux, wants control and low cost Self-hosted on a separate VPS or dedicated server
Large or I/O-heavy database, predictable load Self-hosted on a dedicated server
Need special extensions or superuser access Self-hosted
No ops skills; uptime is critical Managed
Strict compliance needs, with provider certifications Managed (or carefully documented self-hosting)

A common middle path: start self-hosted on the same VPS, move the database to its own server as you grow, and add a replica for failover. See web application architecture.

Quick checklist for self-hosting

Item Done?
Bound to localhost or private network
Strong auth, per-app users
Automated, off-server, tested backups
Monitoring and disk alerts
Security updates scheduled
Replica or recovery plan
