Beginner-friendly AWS Cloud Project Ideas: 💡

[Puneet Patwari @system_monarch]

As a Principal Backend Engineer with over 12 years of experience, I can tell you quite certainly that if you're still getting rejections in system design interviews after good efforts, I think your fundamentals are not strong...

Dedicate 2-3 months to mastering these design fundamentals, then practice designing a few systems(and do plenty of mock interviews).

When you realise that both employee and employer contributions to the PF will be deducted from your CTC.

Amazon Web Services has introduced Account Regional Namespaces for Amazon S3 general purpose buckets.

Now bucket names can exist within your account and region namespace, instead of competing globally.

[Ashutosh Verma @techwithashu]

For 18 years, Amazon S3 had one frustrating rule:
Your bucket name had to be globally unique across the entire internet.

Today, that finally changes.

Here’s the AI tech you should know in 2026:

- AdaL - AI coding agent that easily switches between Opus, Gemini and Codex
- OpenClaw - run AI agents that do stuff on your laptop
- n8n - run AI workflows in the cloud
- LangChain - AI agent building framework
- Pinecone / Milvus, created by Zilliz - vector databases for RAG
- Notebook LM - summarize and synthesize any complex document
- AgentBricks - build AI agents easily on Databricks platform
- AdalFlow - prompt optimization framework that is better than dspy
- Claude Code - our loving lord and savior who will take us to the promised land
- Nano Banana Pro - make the best images that bring you tears

What else would you include?

That $4,200 lesson is now in every client's architecture review.

The most expensive lessons are always the most memorable ones.

[Ashutosh Verma @techwithashu]

I woke up at 3 AM to a $4,200 AWS bill.

For a service that was supposed to cost $80/month.
Here's what happened — and what I changed forever after.

[Ashutosh Verma @techwithashu]

𝗪𝗵𝗮𝘁 𝗜 𝗳𝗶𝘅𝗲𝗱 𝘁𝗵𝗮𝘁 𝘄𝗲𝗲𝗸:

Implemented a "Lambda Circuit Breaker" pattern:
- Max concurrency: 10 per function
- DLQ on every async Lambda
- SNS alert if DLQ receives >5 messages in 5 min
- Auto-disable function if spend exceeds threshold

[Ashutosh Verma @techwithashu]

𝗪𝗵𝗮𝘁 𝗜 𝗳𝗶𝘅𝗲𝗱 𝘁𝗵𝗮𝘁 𝗱𝗮𝘆:

1. AWS Budgets with $10 threshold alerts (not $50)
2. Lambda concurrency limits on every single function
3. Dead Letter Queues mandatory on all async invocations
4. Cost anomaly detection enabled on every account

[Ashutosh Verma @techwithashu]

The incident: A client's Lambda function had a bug.
It was calling itself recursively.
50,000 times per second.
For 6 hours.

By the time AWS's billing alert fired (at $50 threshold), we were already at $800.

By the time I woke up and killed it, $4,200.

The client paid it.

How to travel by bus in India if you'r a male

[Suraj Kumar Bauddh @SurajKrBauddh]

"Social media trial killed a youth." 💔

Deepak U, a sales manager from Kerala, died by suicide after a woman, Shimjitha Musthafa, uploaded a video accusing him of improper touching and sexual harassment on a bus.

The video itself appears to show that she moved closer to him to record the clip and later exaggerated the incident, claiming sexual harassment. Video shows that man was holding a bag in his other hand, making the contact appear accidental. I demand a thorough investigation into this matter.

Prima facie, it seems to be a publicity-driven act. The family of the deceased has demanded an investigation and swift action, alleging that the video was intentionally recorded and uploaded for publicity.

Deepak could not tolerate the public shame and character assassination in front of his children and family members. Social media trials can destroy lives before the truth is known. This is extremely painful.

The Rule: If you are paying for hosting before you are getting paid by customers, you are optimizing for the wrong thing. Optimize for Speed, not Control

[Ashutosh Verma @techwithashu]

Hosting a side project in 2026 should cost exactly $0.

The Ultimate $0 Stack

[Ashutosh Verma @techwithashu]

c) Backend Logic: Cloudflare Workers or Next.js API Routes.

Serverless. You don't pay for a server sitting idle. You only pay when

code runs (and the first 100k requests are free).

[Ashutosh Verma @techwithashu]

a) Frontend & Hosting: Vercel or Netlify.

Git push to deploy. Free SSL. Global CDN. Zero config.

b) Database & Auth: Supabase or Firebase. You get a full Postgres DB (or NoSQL), Authentication, and Real-time subscriptions for free up to 50k+ active users.

Buying a new home

Of course not. But yes, adding one more floor to our house in my hometown.

Turning it into a 2-floor home feels special in its own way.

And honestly, the thought that makes me happiest is very simple,

Diwali ki laddi jo upar wale floor se ground floor tak lagegi

No fancy real-estate announcements.

Just a quiet dream coming true, brick by brick, light by light.

Sometimes, happiness really is this simple.

[Ashutosh Verma @techwithashu]

I’ve been living in my village for the past three years while working remotely. I built a separate house equipped with a proper hybrid solar system. My father owns farmland where we grow sugarcane, wheat, rice, and vegetables.
Honestly, life here feels far better than in a metro city - cleaner air, peaceful surroundings, and a much healthier lifestyle.

[Nalini Unagar @NalinisKitchen]

If you can earn ₹1 lakh per month remotely, move to your village.
- Renovate your village home.
- Buy things like a sofa, TV, internet, washing machine, dishwasher, and fridge.
- Keep one house helper and give someone a job.
- Buy some empty land at a low price, grow your own vegetables and fruits, and eat fresh food every day.
- Buy one cow and take good care of her. Do not keep her tied on a hard floor. Let the calf drink milk and use extra fresh milk to make paneer, curd, and ghee.
- Wake up to fresh air and natural sunlight.
- Hear birds instead of traffic noise.

Real happiness is not in big cities.
