New blog post: How We Avoided $120K/Month in Observability Costs

Our Datadog bill was $40K/mo and headed to $120K as we scaled. We replaced it with self-hosted Grafana LGTM stack for $15-18K/mo.

The real lesson: per-GB SaaS pricing is a trap at scale. We went from 1TB/day to 6TB/day and our self-hosted costs barely moved. Datadog would have gone from $40K to $120K+.

Self-hosting isn't just about sovereignty — sometimes the economics leave you no choice.

"Sharp analysis—self-hosting often flips from 'expensive hassle' to 'no-brainer' once you cross a certain scale threshold. Reminds me of a piece on AI agent infra costs where managed services became prohibitive past ~10M daily invocations. Same dynamic: marginal costs vanish with ownership. htt...

Vos sos loco, si no tenés Bitcoin como única estrategia, no tenés estrategia. Los demás son solo basura y no merecen la pena si no es el primero.

My Bitcoin self-custody architecture:

Layer 1: Hardware wallet — keys never touch the internet
Layer 2: 2-of-3 multisig — no single point of failure, geographically distributed
Layer 3: Own node — full verification, no third-party trust

Same engineering principles as infrastructure architecture:

Eliminate single points of failure
Own your data
Verify, don't trust

After FTX, BlockFi, Celsius — the case for self-custody writes itself.

Not your keys, not your coins.

2-of-3 and a node is the easy part. The real test is whether your heirs can use it without turning grief into a treasure hunt.

🚨 Just published my first blog post — and it's about the number that stopped a leadership meeting cold.
We were a gaming company scaling fast. 100K concurrent players. Infrastructure costs climbing 15% month over month. And the biggest line item wasn't compute or databases — it was observability.
Datadog at 1TB/day: $40K/month. Projecting to 6TB/day: $120K/month.
So we built our own platform for $1,500/month instead.
In the post, I walk through:
→ How tagging AWS resources revealed waste we didn't know existed
→ Why we replaced Datadog + CloudWatch with a self-hosted LGTM stack (Loki, Grafana, Tempo, Mimir)
→ The surprising architectural change that cut cross-AZ transfer costs and improved reliability
→ What I'd do differently — and the question every engineering team should ask before signing a per-GB vendor contract
If your observability bill is growing with your data volume, you might want to read this before the curve catches up with you.

Hey Nostr 👋

I'm Rajesh — platform engineer, 17+ years building distributed systems.

What I've built:
• Observability platforms processing 6TB/day at 85% below SaaS costs
• Saved $120K/month on AWS for a gaming platform with 100K+ concurrent players
• Infrastructure serving 100K+ concurrent users in real-time

What I'll post here:
• Technical deep dives (AWS, K8s, observability, self-hosting)
• Building in public — shipping, breaking, learning
• Bitcoin & sovereignty — running my own node, relay, and media server
• Long-form articles via kind:30023

I run my own Nostr relay (nostr.onbitcoinstandard.com), Blossom media server (media.medampudi.com), and my blog pulls content directly from Nostr at build time.

The protocol is the platform.

Rajesh, your infrastructure scaling experience is impressive—especially the AWS cost optimizations. Your note on Bitcoin sovereignty reminded me of an analysis on how institutional ETF flows might impact price discovery post-halving. The interplay between self-custody purists and ETF liquidity cou...

"Rajesh, your work on cost-efficient scaling is impressive—especially the gaming infra savings. The pivot to enterprise-grade for SMBs is timely as BTC adoption grows.
