5 Things I Wish I Knew Before Starting a Career in Networking !!

If you’re thinking of starting a career in networking, you're not alone—and you're definitely not making a mistake. A career in networking is one of the most future-proof and in-demand paths in the IT world today. From connecting businesses through cloud infrastructures to securing global data transmissions, networking professionals are the backbone of modern digital communication.

In fact, the keyword "career in networking" is more relevant than ever. According to the U.S. Bureau of Labor Statistics, the employment of network and computer systems administrators is projected to grow by 6% through 2032, and roles related to cloud networking and cybersecurity are growing even faster.

Let’s dive into the five things I wish I knew before launching my own journey into this fast-paced, ever-evolving field—along with tips, resources, and quotes from industry experts.

1. Certifications Matter More Than You Think

When I started out, I focused heavily on getting a computer science degree. While that helped me understand the fundamentals, I quickly realized that employers want people who can hit the ground running, and certifications are often the proof of that.

Some of the most recognized certifications that can fast-track your career include:

- CCNA (Cisco Certified Network Associate)

- CompTIA Network+

- Google Cloud Certified – Associate Cloud Engineer

- Google Cloud Certified – Professional Cloud Network Engineer

These validate your knowledge and demonstrate your ability to work on real-world projects.

2. Networking Is More Than Routers and Switches

There’s a common misconception that networking is just plugging in Ethernet cables and configuring switches. While that’s part of the foundation, today’s networking careers encompass cloud platforms, automation, virtualization, security, and DevOps.

Technologies like:

- Software Defined Networking (SDN)

- Network Function Virtualization (NFV)

- API integrations

- Zero Trust Security

- Cloud-native networking in GCP, AWS, and Azure

…are all things modern network engineers must be familiar with.

If you want to future-proof your skillset, start learning Python for network automation, explore tools like Ansible, and get familiar with cloud-based VPCs and hybrid cloud architectures.

3. Labs and Simulations Beat Theory Alone

Reading about subnetting, OSPF, and BGP is one thing. Actually configuring and troubleshooting them is where real learning happens. I wish I had spent more time early on building my own lab at home or using simulators.

Whether you use real gear or virtual labs, hands-on experience is the best teacher.

4. The Cloud Has Redefined Networking

When I got into the industry, cloud was an emerging concept. Today, Google Cloud, AWS, and Azure are redefining how businesses operate—and that includes networking. Traditional network infrastructure is still important, but companies are increasingly looking for cloud-first or hybrid networking professionals.

As a networking pro, you’ll need to know how to:

- Configure Virtual Private Clouds (VPCs)

- Set up VPNs and peering

- Implement cloud firewalls and routing policies

- Monitor and secure hybrid cloud environments

Investing time into Google Cloud training, especially certifications like Associate Cloud Engineer and Professional Cloud Network Engineer, will give you a massive edge.

5. Soft Skills and Collaboration Are Game-Changers

I used to believe that technical skills were everything. But the truth is, your ability to communicate, collaborate, and solve problems with others is just as important as knowing how to subnet.

Modern networking often involves working with DevOps, security, development, and cloud teams. If you can't clearly explain what you're doing, or work in sync with others, you'll hit roadblocks—fast.

According to LinkedIn’s Top Skills Report, communication and problem-solving are consistently ranked in the top 5 for IT roles.

🎯 Pro Tip:

Start documenting your configs, writing how-to guides, and contributing to forums like [Stack Overflow](https://stackoverflow.com/) or [Cisco Learning Network](https://learningnetwork.cisco.com/).

Final Thoughts: Build a Career in Networking That Lasts

A career in networking is rewarding, impactful, and increasingly tied to innovations in cloud, automation, and security. Whether you’re managing data centers or designing hybrid networks in Google Cloud, your skills will always be in demand.

So, what can you do today?

- Pick a certification path (start with CCNA or Google Associate Cloud Engineer)

- Set up your home lab or cloud sandbox

- Join networking communities online

- Practice real-world scenarios regularly

The sky’s the limit—especially when your job is to connect people to it. 🌐
