Every engineering team eventually faces the same question: should we manage our own cloud infrastructure, or hand it to someone who does this full time? The answer depends on your stage, your team's skills, and what you actually want to be spending engineering hours on.
The Real Cost of Self-Managed Infrastructure
Running your own infrastructure is not just about the AWS bill. It is about the engineering time that goes into it.
A typical early-stage team managing their own cloud setup spends somewhere between 20 and 40 percent of senior engineering time on infrastructure tasks — provisioning, patching, debugging outages, reviewing costs, and keeping up with cloud provider changes. That is time not spent on the product.
What Self-Management Actually Requires
For a team of two or three engineers, this is often unsustainable without burning people out.
- At least one engineer with deep cloud expertise (AWS, GCP, or Azure)
- On-call rotation coverage — nights and weekends included
- Continuous security patching and compliance monitoring
- Cost optimisation reviews as your usage grows
- Disaster recovery planning and regular testing
When Self-Management Makes Sense
Self-managed infrastructure is the right call when:
**You have a dedicated platform team.** If you have three or more engineers whose primary job is infrastructure, you have the coverage to do it well.
**Your compliance requirements demand it.** Some regulated industries require direct control over every layer of the stack. If your legal team says you need to own the accounts, you own the accounts.
**You have highly specialised workloads.** Custom GPU clusters, on-premises hybrid setups, or unusual networking requirements sometimes need hands-on ownership.
When Managed Infrastructure Wins
For most product teams — especially those under 20 engineers — managed infrastructure delivers better outcomes at lower total cost.
You Get Senior Expertise Without the Hiring Cost
A good infrastructure engineer commands $180,000 to $250,000 per year in most markets. A managed infrastructure service gives you access to a team of specialists for a fraction of that cost.
Faster Time to Production
A managed provider has done this hundreds of times. They have Terraform modules, runbooks, and monitoring configurations ready to go. What takes an internal team weeks to build from scratch takes days.
24/7 Coverage Without On-Call Burnout
Incidents do not respect business hours. A managed team has dedicated on-call rotations. Your engineers sleep.
The Hybrid Model: Best of Both Worlds
The most common arrangement we see with growing teams is a hybrid approach:
This gives you the control and visibility of self-management with the expertise and coverage of a managed service.
- **You own the cloud accounts.** Billing stays with you. You can see every resource and every dollar.
- **We manage the operations.** Provisioning, monitoring, patching, incident response, and cost reviews are handled by our team.
- **You retain full access.** Nothing is hidden. You can take over at any time.
A Framework for Making the Decision
Ask yourself these questions:
1. Do we have an engineer who wants to own infrastructure as their primary responsibility?
2. Can we staff a 24/7 on-call rotation without burning people out?
3. Is infrastructure work creating a competitive advantage for us, or is it table stakes?
4. What is the cost of a two-hour outage at our current revenue level?
If the answers point toward "no dedicated owner" and "outages are expensive," managed infrastructure is almost certainly the right call.
What to Look for in a Managed Infrastructure Partner
Not all managed services are equal. When evaluating providers, look for:
- **Infrastructure as Code.** Everything should be in Terraform or equivalent. If they cannot hand you the codebase, walk away.
- **Defined SLAs.** Uptime guarantees and incident response times should be in writing.
- **Transparency.** You should have read access to your own infrastructure at all times.
- **No lock-in.** A good partner makes it easy to leave. If they make it hard, that tells you something.
The Bottom Line
Self-managed infrastructure is not inherently better or worse than managed. It is a resource allocation decision. The question is whether infrastructure operations is where your team's time creates the most value.
For most product teams, the answer is no — and that is perfectly fine. Focus on what you are building. Let someone else keep the lights on.
