Hi everyone, so I've decided to make a bold move—switching careers into DevOps!

I know the road ahead comes with challenges, but I’m excited to take them on. To stay accountable and learn faster, I’ll be documenting my journey here, starting with a #30DaysOfDevOps challenge.

Because confidence isn’t knowing you’ll win…
It’s knowing you’re worthy of trying.

[Technical Ben @TechnicalBben]

Lack of confidence is ruining your life.

I didn’t apply cuz I thought I wasn’t good enough.

I didn’t speak up cuz I feared sounding stupid.

I let others go ahead because I thought they deserved it more.
don’t let fear keep writing your story. Start believing.

I make 2M naira monthly working from home in Nigeria, and I didn't pay for a single class all the classes or courses I took were for free.

If you're broke like me you have to be strategic to make such moves.

I'm a testimony that free things if maximize well you will cook!!

I had fun testing these tools as they help quickly:
- Isolate network issues
- Verify security configurations
- Optimize performance

What’s your go-to networking tool when troubleshooting?

Day 15: Networking Tools/Commands for Troubleshooting

Today, I explored networking tools that help diagnose and troubleshoot network issues. These tools are a must-have for any DevOps engineer working with cloud infrastructure.

Here’s what I covered:

[Olisa And The Ops @youfoundolisa]

✅ Ipconfig – Shows network configuration (IP address, gateway, etc.)
✅ Tcpdump – Captures network traffic for analysis
✅ Dig/Nslookup– Query DNS records to troubleshoot domain issues
✅ Wireshark– For deep packet inspection
✅ iPerf – Measures network bandwidth and performance

Networking is like the backbone of the internet. Without these fundamentals, troubleshooting networks would be virtually impossible.

What networking concept took you the longest to grasp?

Day 11: Networking Basics – Understanding the Fundamentals

Networking is a core skill in DevOps, so today, I started diving into networking basics. Understanding how data moves across networks is crucial for managing cloud environments and troubleshooting issues.

[Olisa And The Ops @youfoundolisa]

✅ Subnetting & Gateways – Breaking networks into smaller parts for efficiency (subnetting) and directing traffic via a gateway
✅ NAT– allows multiple devices to share one public IP address.
✅ Port Forwarding – redirects traffic by passing the request to its specific port

Are you team merge or team rebase?

Day 10: Merging vs Rebasing – Understanding the Difference

Today, I explored a very debated topic in Git—merging vs rebasing. At first, they seemed similar, but after some time and practice, I began to understand their differences.

[Olisa And The Ops @youfoundolisa]

Rebasing (git rebase) – Moves commits from one branch onto another to create a linear history.
✅ Rewrites history by applying commits one by one
✅ Avoids merge commits
✅ Useful for cleaner project history
