If you work in DevOps — or wish you did — follow this account.

Here's why. 👇

━━━━━━━━━━━━━━━━━━━━━━

I'm Sumit. DevOps engineer. I post about:

⚙️ Kubernetes — the real parts, not the docs
🏗️ Terraform — at scale, without losing your mind
🔁 GitOps — how to actually implement it, not just talk about it
📡 Observability — because monitoring ≠ knowing what's wrong
🛠️ Platform Engineering — building for developers, not for architecture diagrams
🔐 Linux & security hardening — because compliance is coming for everyone

━━━━━━━━━━━━━━━━━━━━━━

What makes this account different:

Every post is something I've personally done, broken, fixed, or learned from in production. No vendor content. No recycled tips. No hot takes I can't back up.

Just real DevOps from the trenches — 3 to 5 times a week.

And drop a reply: what does your current stack look like? I'm always curious.

Tools I use vs my resume 😭

ACTUALLY USE:
k9s, lazydocker, jq, tmux, Lens, httpie

MY RESUME SAYS:
"enterprise-grade container orchestration solutions"

💀💀💀

Made a GCS bucket public in prod 😱

Didn't realise for 6 hours.

Customer data? No. Build logs? Yes.

Still the worst 6 hours of my career.

Now: Cloud Asset Inventory alerts fire in seconds for any public bucket.

Your worst cloud security mistake? 👇

A guy forgot his Bitcoin wallet password for 11 years.

Not a random wallet either…

It had 5 BTC inside — worth nearly $400,000 today.

The crazy part?

He originally changed the password in college and never remembered it again. 😭

Over the years he tried everything:
• password recovery tools
• old notebooks
• brute-force attempts
• trillions of combinations

Nothing worked.

Recently, as a last attempt, he uploaded old files from his college laptop into Claude AI.

Claude started connecting the dots:
– found an old wallet backup
– identified a hidden file
– spotted an issue in the recovery process
– helped piece together the missing info

And somehow…

the wallet opened. 🔓

After recovering the Bitcoin, he said he’s going to name his child "@DarioAmodei"

Yes, after — the CEO behind @claudeai

This story is wild because Claude didn’t “hack” Bitcoin.

It just did something humans struggle with:
finding patterns in years of forgotten digital chaos.

We’re entering a phase where AI won’t just answer questions.

It’ll recover lost data, debug systems, investigate incidents, and probably save people millions.

That’s both exciting and slightly terrifying.

HOLY FUCKING SHIT OMG CLAUDE JUST CRACKED THIS SHIT, THANK YOU @AnthropicAI THANK YOU @DarioAmodei NAMING MY KID AFTER YOU 😍

@NaveenS16 Kubernetes operators feel simple… until you actually build one.
The reconcile loop gives freedom, but also enough rope to create some truly terrifying state-management bugs.

A lot of operator engineering is basically controlled chaos.

We're building the reliability layer for AI agents.
Open source. Apache 2.0.
Serious contributors welcome.

@freeCodeCamp @irvingpictures So many production issues start quietly. No major outage. No dramatic alert. Just small signals everyone ignores until things suddenly get painful 😅

This is why Bash and Python automation skills are still so valuable in DevOps.

[Sumit ⚙️ DevOps @devopswithsumit]

@awscloud The “scale to zero” + faster autoscaling combo is huge for AI workloads 👀

Agentic systems can be extremely bursty, so paying for idle capacity never made much sense.

Interesting direction for teams building retrieval + search-heavy AI apps on AWS.

[Sumit ⚙️ DevOps @devopswithsumit]

Cut our AWS bill by 40% in ONE week 💸

Dev/test instances running 24/7 on weekends. Nobody using them.

Lambda + EventBridge: stop at 8pm IST, start at 9am.

₹2L/month saved. Zero impact on dev work.

Your company is doing this right now. Go check 👇

@awscloud @RDarrylR @ricardoceci Love seeing community builders get recognized like this 👏

The impact of sharing knowledge, mentoring others, and consistently contributing often reaches far beyond code itself.

Big congratulations to all the new AWS Heroes 🚀

[Sumit ⚙️ DevOps @devopswithsumit]

@Njuchi_ This is such an important point.

A lot of engineers jump straight to Terraform, GitOps, or AI tools without ever experiencing the pain those tools were designed to solve.

That context changes how you design infrastructure completely 👏

[Sumit ⚙️ DevOps @devopswithsumit]

@TheTechMaharaj KubeCon Mumbai is going to be massive for the cloud-native community 🔥

The networking, real-world scaling stories, and hallway conversations alone are worth attending.

Excited to see builders, SREs, platform engineers, and DevOps folks all in one place 🙌

[Sumit ⚙️ DevOps @devopswithsumit]

My suggestion: before buying anything on @letsblinkit & @blinkitcares , always check whether the item is returnable or not. If it isn’t, better avoid it and purchase from other platforms. Otherwise, you may regret it later and realize you could’ve gotten better quality at a reasonable price elsewhere (@Meesho_Official)with a return policy.

DevOps salaries in India 2025 🇮🇳 (no BS):

0–2 yrs: ₹6–12L
2–5 yrs: ₹15–35L
5+ yrs: ₹40L+
Remote/product: 2–3x

Are you being underpaid?

DM me your stack + experience. I'll tell you honestly 💪

@autobase_tech Not nearly enough.

A lot of teams “have HA” on paper, but the first real failover test happens during an actual outage.

That’s when things get very educational.

[Sumit ⚙️ DevOps @devopswithsumit]

VACUUM ANALYZE your PostgreSQL. Right now.

Dead tuples pile up on write-heavy tables. Slows EVERYTHING.

Auto-vacuum isn't enough.

Manual VACUUM weekly = night and day query speed difference 🔥

tmux saved my life 🙏

SSH dropped MID prod migration.

Everything. Still. Running.

tmux keeps terminal sessions alive when you disconnect.

Should've learned this year 1.

Real talk — what CI/CD tool is your team running in 2026?

→ GitHub Actions
→ GitLab CI
→ Jenkins (I see you 👀)
→ CircleCI / Other

Drop your stack + why below 👇

Genuinely curious what Indian teams are using

@SarathV174193 Exactly,

One memory leak and suddenly the node turns into a battle royale.

Then everyone blames Kubernetes instead of the missing 4 lines of YAML.

[Sumit ⚙️ DevOps @devopswithsumit]

As a verified DevOps guy — #1 k8s mistake I see in Indian startups:

No resource requests or limits. Zero.

One bad pod eats your WHOLE node.

It's 4 lines of YAML. Come on 🙏

resources:
requests: {cpu: "250m", memory: "256Mi"}
limits: {cpu: "500m", memory: "512Mi"}

Your Kubernetes Secrets aren't secret 😬

base64 is ENCODING. Not encryption.

Anyone with kubectl access can read them in 10 seconds.

Use Sealed Secrets or External Secrets Operator.
