Managed DevOps vs Hiring SREs: Complete Cost/ROI Model

The $500K Question

Your CTO asks: "Should we hire 2 SREs or use a managed DevOps service?" The obvious answer seems to be hiring—you get dedicated people on your team. But when you do the math, the reality is surprising.

Hiring 2 senior SREs: $500K+/year all-in, 3-6 months to productivity, single points of failure during vacation/sick leave.
Managed DevOps team: $120K-$180K/year, productive from day 1, 24/7 coverage, no PTO gaps.

Time-to-Value Analysis

Hiring In-House: 3-6 Months

Month 1-2: Job posting, interviewing, offer negotiation
Month 2-3: Notice period at current employer
Month 3-4: Onboarding, learning your stack
Month 4-6: Ramp to full productivity

Result: 3-6 months before seeing ROI

Managed DevOps: Immediate

Week 1: Onboarding call, access provisioning
Week 2: Infrastructure audit, priority roadmap
Week 3-4: First optimizations deployed
Month 2+: Full operational support + improvements

Result: Positive ROI from week 1

Decision Framework: When to Choose Each Option

✅ Choose Managed DevOps When:

You're pre-Series B (under 50 employees)
DevOps is not your core competency
You need 24/7 coverage but can't hire 4+ SREs
Your infrastructure is standard (Kubernetes, AWS, common stack)
You need immediate results (can't wait 3-6 months)
Your budget is under $200K/year for ops

⚠️ Choose In-House SREs When:

You're post-Series B (100+ employees)
You have highly custom/proprietary infrastructure
You need dedicated, full-time focus (200+ hours/month)
DevOps IS your product (infrastructure company)
You can hire 4+ SREs for proper rotation/coverage
Your budget exceeds $500K/year for ops

🎯 Hybrid Approach (Best of Both):

Start: Managed DevOps for immediate coverage
Grow: Hire 1 DevOps engineer as liaison/manager
Scale: Build in-house team, keep managed as 24/7 backup
Result: Best economics + no single points of failure

Real Customer Case Studies

Case Study 1: Series A SaaS ($5M ARR)

Challenge: Needed 24/7 ops, couldn't justify $500K for 2 SREs
Solution: Managed DevOps at $12K/month
Results: $384K/year saved, 99.9% uptime, passed SOC 2 audit

Case Study 2: Series B Fintech ($20M ARR)

Challenge: Had 1 SRE, couldn't cover on-call alone
Solution: Hybrid—kept SRE, added managed for 24/7 coverage
Results: SRE no longer burnt out, MTTR reduced by 60%

# Your Custom ROI Calculator ## Inputs (customize these): num_sres = 2 # How many SREs would you hire? sre_salary = 150000 # Average senior SRE salary in your market benefits_rate = 0.30 # Benefits as % of salary equity_bonus = 0.15 # Equity/bonus as % of salary recruiting_cost = 30000 # Per hire onboarding_months = 3 # Time to full productivity managed_cost_monthly = 12000 # Managed service cost ## Calculation: hire_year1 = (num_sres * sre_salary * (1 + benefits_rate + equity_bonus)) + \ (num_sres * recruiting_cost) + \ (num_sres * (sre_salary / 12) * onboarding_months) hire_year2plus = num_sres * sre_salary * (1 + benefits_rate + equity_bonus) managed_yearly = managed_cost_monthly * 12 ## Results: year1_savings = hire_year1 - managed_yearly year1_roi = (year1_savings / managed_yearly) * 100 print(f"Year 1 Savings: ${year1_savings:,.0f}") print(f"Year 1 ROI: {year1_roi:.0f}%") print(f"3-Year Savings: ${(hire_year1 + 2*hire_year2plus - 3*managed_yearly):,.0f}")

Bottom line: For most startups and scale-ups, managed DevOps delivers 70-80% cost savings with faster time-to-value. Hire in-house when you're large enough to justify 4+ person teams with proper rotation.
