Saas for Businesses
Playbooks and case studies covering saas for businesses.
Managed Cloud vs. Raw IaaS: Pick One Before You Scale
Most managed cloud vs IaaS comparisons argue price-per-vCPU and deployment speed. Both miss the axis that determines regret at 18 months. Here's a decision framework built around the resource you actually don't have enough of.
Migrate a Live MySQL Schema Without Downtime
Most guides tell you to run gh-ost and walk away. They skip the part where the cutover step — not the copy — is what actually causes the 2 a.m. outage. Here's the playbook that survives production write load.
Temporal vs. Celery vs. BullMQ: Pick One for Durable Jobs
A dimension-by-dimension look at Temporal, Celery, and BullMQ for durable workflow orchestration. When your queue is actually the wrong tool — and when a retry decorator and a state column would fix it.
CRON Job Failure Cheatsheet: Diagnose, Alert, Recover
A dense reference for backend engineers whose scheduled jobs fail silently in production. Covers heartbeat monitoring, alert patterns, and recovery playbooks for missed runs.
5 Mistakes Teams Make When Adding Real-Time to a Batch System
Retrofitting real-time onto a batch system rarely fails because of Kafka tuning. It fails because your schema was designed to be overwritten in bulk. Here are the five structural mistakes we see teams repeat, and how to recover.
Event Sourcing Is Not a Database Pattern
Most teams implement event sourcing as an event log next to their CRUD tables and end up with the complexity of both models and the benefits of neither. Here's the mental inversion that actually makes it work.
Build vs. Buy Your Internal Ops Dashboard
Most build-vs-buy comparisons for internal tools argue about cost and speed. Both are the wrong axes. The one that predicts regret is the rate of change of your ops logic — here's how to score it honestly.
Synchronous API vs. Async Queue: Pick One and Commit
Retrofitting queues onto slow endpoints one at a time creates a hybrid mess. Here's the real decision rule: who owns the failure, the caller or the callee?
5 Mistakes Teams Make When Migrating from Monolith to Microservices
Most monolith to microservices migration guides describe the happy path. This is the other one: the five failure modes that show up after the first two services are live and the shared database is still lying to you.
Idempotent Webhook Consumers: A Step-by-Step Guide
A hands-on walkthrough for building webhook handlers that survive provider retries without double-charging or double-shipping. Real Postgres schema, real Node code, and the race condition most tutorials miss.
Your Integration Is Not Done When the Data Flows
Passing QA is not the same as being production-ready. The real failure surface of an integration isn't the happy path — it's what happens when a record breaks, and who owns it when it does.
Feature Flags Are Not Config. Treating Them That Way Breaks You.
A feature flag is a decision with an owner and a death date. A config value is state. When you store them in the same table, you lose the guardrails that make flags safe — and production pays the bill.
