Infrastructure Decisions for Scalable Platforms

Infrastructure decisions should start with failure modes, not features. The question is not "what can this handle?" but "what happens when it doesn't?"

For most web platforms, Docker-based deployment is the right choice. Images are immutable. Environments are reproducible. Rollback is a command, not a process. The container boundary forces clean separation between application and infrastructure.

Nginx as reverse proxy gives precise control over traffic routing, SSL termination, rate limiting, and connection handling. I configure it as the single point of entry — everything else is internal.

For cloud infrastructure, I prefer managed services for databases and object storage, self-managed compute for application servers. This balances operational simplicity with cost efficiency and control.

Monitoring is not optional: structured logs, uptime monitoring, and alerting on error rate spikes are baseline requirements before any platform goes to production.
