@ParodyPathaan Are you kind of stupid or something? The time was different, live in present. This is how market works.

Website revamp in progress.

Exploring the design, structure, and user experience before moving into implementation.

More to come.

A cron job is scheduled to run once at 3 AM.

Today, it executed twice.

No manual trigger.
No duplicate servers.
No retries.

The code looks fine.

What could have caused this?

Did this hit you with a wave of nostalgia? 👀

5/5

There isn't a universal "best" deployment strategy.

The right choice depends on your system, traffic, infrastructure, and rollback requirements.

Reliable systems aren't just built with good code.

They're built with safe deployments.

[Anwar @anwar_builds]

Shipping code is easy.

Deploying it safely is where engineering begins.

Most production incidents aren't caused by writing bad code.
They're caused by releasing good code the wrong way.
Here are 4 deployment strategies every backend engineer should know 🧵👇

"We need microservices."

Not always.

Start with a modular monolith.
Extract services when they're truly needed.

Complexity is easy to add, hard to remove.

Great architecture solves today's problems without creating tomorrow's.

Modular monolith or microservices?

Most startups don't fail because they can't scale.

They struggle because they haven't learned enough about what they're building yet.

Don't let the architecture get ahead of the product.

[Anwar @anwar_builds]

One of the best architecture lessons I've learned came from watching someone else's project fail.

My default recommendation:

Start with a modular monolith.
Let real business needs create the pressure to move toward microservices, not the other way around.
