## The routes

### Observability & APM

The licence is not the bill. Ingest is the bill — and it grows with your traffic, not your headcount.

- 23 products compared
- Guide: https://www.thetechbag.com/browse/devops/observability-apm
- Boundary terms resolved: Monitoring vs observability · Observability vs APM · Logs vs metrics vs traces · APM vs RUM vs error tracking

### Databases & Data Tools

The licence you are quoted is for the database. The cost you will carry is the migration — and nobody quotes that.

- 28 products compared
- Guide: https://www.thetechbag.com/browse/devops/databases-data-tools
- Boundary terms resolved: Database monitoring vs APM · Managed vs self-hosted vs DBaaS · Migration vs replication · Compatibility vs conversion

### Developer Tools

This is the one route here that meters per seat — and the seat count you are quoted is rarely the seat count you end up paying for.

- 36 products compared
- Guide: https://www.thetechbag.com/browse/devops/developer-tools
- Boundary terms resolved: SCM vs CI/CD · SCM vs DevOps platform · IDE licensing vs seat licensing · Secrets management vs configuration
