Managing AWS Without a Dedicated SRE: A Practical Guide

Your company runs production workloads on AWS but you don't have a Site Reliability Engineer, a Platform team, or even a full-time DevOps person. Your developers handle infrastructure alongside feature work. You, as the engineering manager, are ultimately responsible for keeping things running.

This is completely normal. Most companies with 5-50 engineers are in exactly this position. You don't need an SRE title on the team. You need what an SRE would give you: regular checks, cost reviews, and a way to catch problems before customers do.

Here's how to get there without the headcount.

What you're actually missing

When you don't have a dedicated SRE, these are the things that tend to slip:

Proactive monitoring: Nobody is watching for slow degradation — CPU creeping up, disk filling slowly, certificates expiring next month. You find out when it breaks. Regular audits: Security groups accumulate permissive rules. IAM users get created and never cleaned up. S3 buckets become public. Nobody checks because nobody's job is "check." Cost awareness: The AWS bill grows 5% per month and nobody questions it because nobody owns it. Incident readiness: When something breaks at 2am, there's no runbook. The person who set it up might not even work here anymore. Operational knowledge: Everything lives in one person's head. If they leave, you're starting from scratch.

The five things to put in place

1. Establish a weekly check-in rhythm

Dedicate 30 minutes per week to infrastructure. Review the bill, check for alerts, look at any monitoring dashboards you have. Even this basic cadence catches most surprises.

The hard part is making it happen consistently. It's the first thing that gets dropped when feature deadlines loom.

2. Set up billing alerts

Go to AWS Budgets and create a monthly budget with alerts at 80% and 100% of expected spend. This takes 5 minutes and prevents bill shock.

3. Enable CloudTrail

If it's not on, turn it on. CloudTrail records every API call in your account — who did what, when. Without it, incident investigation is guesswork.

4. Tag your resources

Implement a tagging policy — at minimum, tags for Team, Environment (prod/staging/dev), and Purpose. This lets you answer "who owns this?" and "can we turn this off?" without a 30-minute investigation per resource.

5. Create a simple incident response process

Write down: who gets paged, how they access the AWS console, what they check first, and who they escalate to. One page is enough. The goal is "anyone can start investigating" rather than "only Sarah knows how."

Scaling without hiring

The five steps above are the minimum. But they still require someone to consistently execute them — and that's where most teams fall short. Not because people are lazy, but because they're busy building the product.

This is the gap plainfra fills. It's not a replacement for an SRE — it's the automated version of the things an SRE would do first: the regular audits, the cost reviews, the security checks, the "what changed this week?" reports.

Weekly health reports replace the weekly check-in you keep meaning to do but never get to. They arrive in your inbox every Monday — prioritised, across all your accounts, with RED/AMBER/GREEN indicators. No console login required. On-demand questions give you instant answers without bothering your team:

> "What's our current infrastructure risk profile?"

"Are there any resources that have been idle for more than a week?"

"What would our bill look like if we right-sized our EC2 instances?"

Ticket creation turns findings into assigned work. plainfra identifies a problem, you create a Jira ticket with one click, assign it to the right developer, and track it to resolution. The loop is closed.

For $79/mo, you get continuous coverage of the things an SRE would review first — security posture, cost hygiene, and operational health. It won't replace a full SRE hire, but it covers the regular checks that most teams skip.

And it's there when things go wrong. When something breaks at 2am and you need to understand what changed, plainfra is already connected and ready to answer. No signing up under pressure, no figuring out console access. Just ask.
