As technology changes quickly, many companies are moving to the cloud. This means that jobs like Network Engineers, who manage computer networks in offices, are also changing. Now, there’s a big demand for Cloud Network Engineers who manage networks online in the cloud. Moving from a Network Engineer to a Cloud Network Engineer can bring more job opportunities, better pay, and the chance to work with the latest online technology that many companies are using today.

Network Engineer

A Network Engineer is a person who helps set up and maintain the computer networks that allow devices like computers, printers, and phones to communicate with each other in a company. Their job is to make sure the network runs smoothly, without any problems, and to fix any issues that come up. They are also responsible for protecting the network from hackers and other security threats. Network Engineers are important because they ensure that everyone in the company can access the network to do their work.

Roles and Responsibilities

• Design and Build Networks: Network Engineers plan and create computer networks for businesses. They decide what equipment is needed and how it will be connected. They set up local networks (LAN), which connect computers in one office, or larger networks (WAN), which connect computers across many locations. They also set up VPNs that allow people to work securely from home.

• Monitor Network Performance: Network Engineers ensure it works well after setting up the network. They monitor how fast data moves, check for any problems, and ensure everything is running as expected. If something goes wrong, they act quickly to fix it.

• Fix Network Issues: If the network slows down, stops working, or has any other issues, the Network Engineer is responsible for finding the cause and solving the problem. This could involve fixing a connection, repairing a router, or working with Internet providers to get things back on track.

• Protect the Network: A big part of a Network Engineer’s job is securing the network. They set up firewalls and other tools to protect the network from hackers and viruses. They also make sure that only authorized people can access the network and sensitive data.

• Maintain and Upgrade Network Equipment: Over time, networks need to be updated to keep up with new technology. Network Engineers regularly update and replace old equipment, install new software, and ensure the network meets the company's needs as it grows.

Skills Required for a Network Engineer

• Understanding Networks: Network Engineers need to know the basics of how computer networks work. This includes understanding how devices like computers and printers connect using common protocols like TCP/IP. They should be familiar with IP addresses and how to set up and manage these connections to ensure everything runs smoothly.

• Problem-Solving: When network issues arise, Network Engineers must quickly figure out what’s wrong and fix it. This means being able to diagnose problems by looking at network traffic, checking device settings, and solving hardware issues. Good problem-solving skills help keep the network running without interruptions.

• PuTTY: PuTTY is a program used to connect to network devices remotely. It supports protocols like SSH and Telnet, which let engineers manage and configure devices from afar. This tool is important for remote access and handling network issues without being physically present.

Cloud Network Engineer

A Cloud Network Engineer works with computer networks that are hosted in the cloud, meaning they manage virtual networks that are set up and run on the internet through services like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. Unlike traditional networks that use physical equipment, cloud networks use virtual resources. This job involves setting up, managing, and securing these online networks to ensure they work well and meet the company’s needs. Cloud Network Engineers help businesses move their IT systems to the cloud and keep them running smoothly and securely.
