Infrastructure Management: In-House vs Managed

You run your own servers, and one or two people on your team know how they all fit together. Now you are deciding whether to keep building that capability in-house or hand the infrastructure to a provider. Both are reasonable answers, and the right one depends on three things: how much of the work is routine, how much cover you need outside working hours, and how much currently depends on one person.

This article breaks down what infrastructure management involves, what each option really costs, and when each one wins. If you are comparing full costs rather than salaries alone, the glossary entry on total cost of ownership is a useful frame, and the hidden complexity tax covers the staffing side of running public cloud.

What infrastructure management actually involves

Most of the work is recurring, and most of it is invisible until it is missed.

Patching operating systems, hypervisors and firmware, and testing that nothing broke
Monitoring and on-call, including someone who answers the alert at night
Backups and restore testing, not just backup jobs
Capacity planning, so you add resources before you run out
Security hardening and access reviews, including removing people who have left
Hardware lifecycle, from failed disks to end-of-life servers
Incident response, from first alert to written follow-up
Documentation, so the next person can do any of the above

Very little of this differentiates your business. It has to be done well, but doing it better than everyone else rarely wins you a customer.

What in-house really costs

Salary is the visible part. The median annual wage for network and computer systems administrators in the US was $96,800 in May 2024, according to the Bureau of Labor Statistics. Benefits, tools, training, recruiting and the months a new hire spends learning your environment come on top.

Coverage is the part teams underestimate. A week has 168 hours and one person works about 40 of them. Round-the-clock cover cannot come from one person, and even a light on-call rotation needs several people before it stops burning them out.

Then there is key-person risk. When one engineer holds most of the knowledge, every holiday, resignation or sick day becomes an operational risk.

What managed costs you

Handing infrastructure to a provider is not free of trade-offs, and it helps to name them before you sign.

Changes go through someone else. Even with a responsive team, a change you could make yourself in five minutes becomes a request.

The provider learns your environment over time. Context your own engineer has built over years does not transfer on day one.

Engineer time is finite. Most managed plans include a set amount of hours or a defined scope. Large projects may need more.

You still need an owner. Someone internal has to make decisions, set priorities and hold the provider to account.

When in-house is the better choice

Infrastructure is your product. If you sell hosting, networking or a platform where the infrastructure itself is the value, keep it in-house.

You already have a strong operations team at scale. If you already run reliable on-call with several engineers, the coverage problem is solved and the case for outsourcing is weaker.

Your hardware is unusual. Specialised equipment or tightly controlled on-premises environments may not fit a provider's platform.

You need control over every change. Some teams need direct control more than they need the hours back.

When managed is the better choice

Your team is small and the infrastructure work crowds out product work. Our post on what managed cloud takes off a small IT team goes into this.

You need cover outside working hours and cannot staff a rotation.

One person holds the keys. Spreading that knowledge across a provider's team removes a single point of failure.

You are outgrowing your current servers. If you are already weighing moving from a dedicated server to managed cloud, the operations question comes with it.

The hybrid most teams end up with

For most growing teams the answer is not all or nothing. They keep ownership in-house and hand off the routine operations.

Stays in-house: architecture decisions, the application, data and access decisions, and managing the provider.

Handed off: patching, monitoring, backups, hardware, platform upgrades and first response to incidents.

That split keeps the decisions with the people who understand the business and moves the routine work to people who do it all day.

Where InMotion Cloud fits

InMotion Cloud is built for the hybrid model. Every plan includes the same managed services: monitoring, backups, operating system patching and hardening, incident response and more, delivered by senior engineers with no first-line queue.

What varies is how much engineer time you get. Virtual Private Cloud plans run from 3 engineer hours a month on Explorer to 40 on Large. Managed Private Cloud is scoped to your environment, with engineer time set to match.

What we do not do is replace your developers or the person who owns your infrastructure decisions. If you hand us the routine operations, someone on your side still sets direction. That is the arrangement that works best for both sides.

Summary

In-house infrastructure gives you direct control and deep context, at the cost of salaries, coverage gaps and key-person risk. Managed infrastructure gives you a team and coverage, at the cost of some speed and control over changes. Most growing teams keep ownership in-house and hand off the routine work.

Frequently asked questions

Is managed infrastructure cheaper than in-house? It often is for small teams, once benefits, tooling, coverage and key-person risk are counted. For large teams with mature operations, in-house can cost less.

What does an infrastructure management provider usually handle? Patching, monitoring, backups, hardware, platform upgrades and incident response. Your application and data decisions normally stay with you.

Do I still need an IT person if I use a managed provider? Yes. Someone internal should own architecture decisions, priorities and the relationship with the provider.

How do I compare the costs fairly? Add up salaries, benefits, tools, training, out-of-hours cover and hardware for in-house, then compare that with the provider's full monthly price and what it includes.

Can I move back in-house later? Usually, if you keep ownership of your architecture and documentation and avoid tools that only work on one provider.
