Uptime Isn’t Enough — My Shift from SRE to FinOps

Sai Krishna — Mon, 04 May 2026 06:01:00 +0000

Hey Dev.to 👋

I’ve spent the last several years working as a Staff Site Reliability Engineer, focused on keeping systems reliable, scalable, and — most importantly — up.

Like many SREs, my world revolved around:

SLAs, SLOs, and error budgets
Incident response and postmortems
Observability, automation, and resilience

And while uptime is critical… I started noticing something:

👉 We rarely talked about the cost of reliability.
⸻

The Shift

As systems scale, so do cloud bills.
And at some point, I realized:

Keeping systems up is only half the problem — keeping them cost-efficient matters just as much.

That’s what pulled me toward FinOps.

Not as a replacement for SRE — but as a natural extension of it.
⸻

Why FinOps?

Because:

Overprovisioning is easy under pressure
“Just scale it” often hides inefficiencies
Reliability decisions directly impact cost

And yet, cost is often treated as someone else’s problem.

It shouldn’t be.

⸻

Where I’m Headed

I’m currently exploring:

Cost-aware architecture patterns
Rightsizing and workload optimization
Bridging engineering and finance conversations
Building a culture where cost is a first-class metric ⸻

What to Expect Here

I’ll be sharing:

Practical FinOps learnings from an SRE perspective
Real-world trade-offs between reliability and cost
Tools, strategies, and mistakes along the way

⸻

Let’s Connect

If you’re working in:

SRE / Platform Engineering
Cloud Infrastructure
FinOps or cost optimization

…I’d love to learn from you.

⸻

Less downtime. Less waste. Better systems.

Let’s build that together 🚀
