AWS에 대해 더 많이 배울수록 기본을 더 존중합니다.

One thing I have noticed lately while learning cloud is how easy it is to feel behind, especially online.

You open LinkedIn or YouTube and see people talking about Kubernetes, advanced architectures, multi-cloud setups, and dozens of AWS services, as if everybody already understands everything.

Meanwhile, some people are still trying to fully understand what a VPC even does.

Many people quietly feel pressured to skip fundamentals because everyone else seems “ahead.”

I used to feel that way too.

At first, I thought learning AWS was mostly about memorising services and launching servers.

But once I started learning AWS more deeply, I realized the cloud is much bigger than that.

Things like VPCs, subnets, routing tables, NAT gateways, and security groups felt overwhelming at first.
Not because they were impossible to learn, but because many explanations made them sound overly technical.

At some point, I decided to create a video explaining VPCs to myself using a simple neighborhood analogy.

And that changed a lot for me.

For the first time, things genuinely started making sense.

The VPC became the neighborhood itself.

Public subnets felt like major roads anyone could access publicly.

Private subnets became quieter streets where sensitive resources like databases stay protected.

Even security groups stopped feeling like random rules and started making sense as gates controlling who can enter specific buildings.

That small shift changed the way I understood networking. I stopped trying to memorize definitions and started understanding why companies structure cloud environments the way they do.

That is the difference between passive learning and real understanding.

Watching tutorials feels productive, but troubleshooting teaches deeper lessons. I even wrote about that in my previous newsletter.

For example, troubleshooting my web server when it refused to open taught me more about security groups than any tutorial. I had accidentally blocked traffic to my EC2 instance and had no idea why my application had gone silent.

Many people underestimate how normal confusion is in cloud computing.

Some concepts take time. Sometimes you revisit the same topic three or four times before it finally clicks.

Even experienced engineers still go back to fundamentals once in a while.

You do not need to understand everything immediately.

The internet sometimes makes tech careers look very linear.
Study. Get certified. Get hired.
But real learning usually looks messier than that.

There are moments of confusion. There are things you break accidentally. And there are concepts that make no sense today but suddenly click weeks later.

And that is probably how it is supposed to be.

So these days, I am trying to focus less on looking impressive online and more on actually understanding what I am learning or building.

The deeper I go into AWS, the more I realize strong fundamentals make advanced concepts less intimidating.
