Cost Optimization
Cloud bills have a way of growing while you're looking the other way. The frustrating part is that most of the waste isn't from big decisions; it's a pile of small defaults nobody revisited. A few hours of auditing can often cut a bill substantially without touching your architecture. The trick is to be systematic instead of guessing where the money goes.
Start with the billing dashboard and group costs by service and by resource tag. If your resources aren't tagged, that's your first fix, because you can't optimize what you can't see. Look for the top three line items and ask one question about each: is this doing work that matters right now? Idle load balancers, oversized databases, and forgotten staging environments are the usual suspects.
Compute is where most of the money hides. Instances sized for a launch week that never scaled back down, dev machines running around the clock, and snapshots accumulating forever all add up. Right-sizing is less scary than it sounds: check actual CPU and memory usage over a couple of weeks, then drop a size and watch. Most apps use a fraction of what they're provisioned.
Storage and egress are the quiet ones. Old logs, duplicate backups, and unused volumes linger because deleting them feels risky. Set lifecycle rules so cold data moves to cheaper tiers automatically and old snapshots expire. On egress, check whether you're serving assets through your app server when a CDN would be cheaper and faster. Image optimization alone can shrink transfer costs noticeably.
Managed services are worth their price when they save you time, and a waste when they sit idle. A managed message queue with zero messages, a search cluster nobody queries, or a monitoring plan priced per host you no longer run are all candidates for cancellation. Before deleting, grep your codebase for connection strings and check the service's metrics for recent traffic. Five minutes of caution beats an outage.
Set a budget alert at a level that would actually surprise you, and route it somewhere you'll see it. Tag every resource at creation time with an owner and an environment. Schedule non-production environments to shut down outside working hours; this alone can halve their cost. Review the bill monthly, not annually, because small drifts are easier to fix than big ones.
Finally, resist the urge to optimize prematurely. If your bill is small, your time is worth more spent on the product. The goal isn't the cheapest possible infrastructure; it's paying for what you use and knowing why. That awareness is what keeps a lean indie operation lean.
