Buyer's Guide · Build vs Buy

Managed DevOps vs hiring in-house.
The real math.

The job-ad salary is about 60% of the real number, and one engineer is 0% of an on-call rotation. This page does the build-vs-buy math honestly: loaded costs, coverage, hiring time and risk, with worked examples you can rerun on your own numbers. It also says plainly when hiring in-house wins, because sometimes it does.

The number the job ad doesn't show

Fully-loaded cost is salary times roughly 1.25–1.4 once payroll taxes, insurance, equipment, seats and stipends land. Illustrative 2026 market numbers, stated so you can swap in your own:

Senior DevOps / SRE hire Typical salary Loaded (×1.25–1.4)
United States $150K–$200K $190K–$280K/yr
Western Europe €80K–€130K €100K–€180K/yr
India (metro) ₹30–60 LPA ₹38–84 LPA

Add the costs that never make the spreadsheet: 2–4 months to hire in a market where senior cloud talent gets counter-offered, another 1–2 months of ramp-up on your stack, recruiter fees if you use one, and the restart penalty when they leave (median tenure for infrastructure engineers runs 2–3 years). None of this makes hiring wrong. It makes the comparison honest.

The coverage problem: one engineer is not a rotation

Here's where the math turns sharply. If production matters at night, someone has to hold the pager at night. A sustainable rotation needs three to four people minimum; fewer and you're converting salary into burnout and, eventually, a resignation letter. So the real in-house question is rarely "can we afford one DevOps engineer?" It's "can we afford three, when the daytime workload justifies one?"

A worked example. A 25-engineer SaaS company wants CI/CD ownership, Kubernetes care, and 24×7 incident response. In-house that's a three-person rotation: roughly $570K–$840K/yr loaded in the US, or ₹1.1–2.5 Cr/yr in India. The market range for an SLA-backed managed DevOps team-slice (from our rates guide) is $5K–$20K/month, i.e. $60K–$240K/yr, because the vendor amortises the night shift across clients. The spread between those two lines is the entire managed-services business model, and it's why the answer flips as you grow: at some scale, the workload fills all three seats and hiring wins.

What each option is actually good at

In-house hire Managed DevOps
Time to productive 3–6 months (hire + ramp) Days to weeks
24×7 coverage Needs 3+ people Included, SLA-backed
Product context Deep, compounds yearly Good, but shared attention
Breadth of scar tissue One stack's worth Many environments' worth
Key-person risk High until team of 3+ Vendor's problem, contractually
Exit cost Re-hire cycle Depends entirely on exit terms

When to hire in-house (yes, really)

  • Infrastructure is your product or a core differentiator. Then platform knowledge is strategy; own it.
  • The workload is permanently full-time-plus. A team past ~50 engineers usually generates enough platform work to fill a rotation with room to spare. (What that team should look like: DevOps vs SRE vs Platform Engineering.)
  • Compliance requires it. Some regulated environments want specific operational roles on payroll. Check before you architect around a vendor.

The hybrid path most teams actually take

Build-vs-buy is a false binary; sequencing beats choosing. The managed team stands up the platform and the on-call, documents everything in runbooks as a deliverable, then helps you interview your first infrastructure hires and onboards them into a working system. Your engineers inherit a platform instead of a blank page, and the vendor's job shrinks to audits and escalation. That only works if the exit terms make it possible: everything in your accounts and repos from day one, and handover treated as a milestone, not a favour. It's how we prefer to work; many of our clients reduce or end engagements once their in-house team owns the work, and we consider that a successful outcome.

Frequently asked questions

What does a DevOps engineer actually cost fully loaded?

Take the salary and multiply by roughly 1.25 to 1.4 for payroll taxes, benefits, equipment, software seats and office or remote stipends. In the US, a senior DevOps or SRE salary of $150,000 to $200,000 becomes roughly $190,000 to $280,000 loaded. In India, a senior at 30 to 60 LPA becomes roughly 38 to 84 LPA loaded. Then add what the spreadsheet hides: 2 to 4 months of hiring time, ramp-up, and the cost of covering their on-call, vacations and eventual departure.

Why does 24/7 coverage change the build-vs-buy math?

Because one engineer cannot be a rotation. Sustainable 24/7 on-call needs at least three to four people sharing the pager; below that you are buying burnout and attrition. That means genuine round-the-clock coverage in-house starts at three-plus loaded salaries even if the daytime workload only justifies one. Managed services amortise the night shift across many clients, which is why SLA-backed coverage can cost less than a single hire.

When is hiring in-house clearly the right call?

Three signals: the infrastructure is the product or a core differentiator (a platform company, an infra-heavy SaaS); there is a steady full-time-plus workload for years, not a project hump; or you are past roughly 50 engineers and platform work is now organisational, not just technical. At that point, hire, and use outside help only for bootstraps and audits.

Can we start with managed DevOps and move in-house later?

Yes, and done right it is the cheapest path: the managed team builds the platform, documents it in runbooks, then helps interview and onboard your first hires into a working system instead of a greenfield. Insist on exit terms that make this real: everything in your accounts and repos from day one, documentation as a deliverable, and a defined handover. Many InfraZen clients reduce or end engagements once their in-house team owns the work; we consider that a successful outcome.
