Shipping often is safer than shipping rarely, if each change is small and easy to undo. How feature flags separate deploying code from releasing features, how canary and blue/green deploys limit the blast radius, and the rollback habits that make a bad deploy a five-minute event.

Lambda aliases with weighted traffic, and CodeDeploy canary or linear configurations that roll back on CloudWatch alarms.
ECS rolling, blue/green and canary deployments with alarm-based rollback.
AWS AppConfig for feature flags with gradual rollout and automatic rollback, or a flag service you already use.
Every deploy is one command or one click to undo, and someone has done it recently.
Database changes are backwards compatible (expand, then contract), so rolling back code does not need rolling back data.
Deploy small changes often; a deploy with one change is easy to diagnose.
Watch the error rate and the business metric for fifteen minutes after each deploy, or let the canary do it.
Avoid deploying right before you stop working for the day or the weekend.
Once a month: what changed in tech that month and what it means for you, from cloud and AI to security and the tools you build with. Every item links to its source. No sales pitch, unsubscribe in one click.

Database Migrations Without Downtime: Expand and Contract, Locks, and the Postgres Operations That Bite
Most schema changes are safe; a few take locks that stop every query on a busy table. The expand-and-contract pattern for renames and type changes, the Postgres operations to treat with care (indexes, constraints, column rewrites), lock timeouts, and why the migration and the deploy must be separate steps.

Timeouts, Retries and Idempotency: The HTTP Habits That Stop Double Charges
Every network call ends in success, failure or "we don't know". The third causes duplicate orders, double charges and stuck jobs. How status codes, timeouts, retries with backoff and idempotency keys fit together, with the limits on API Gateway and Lambda.
