My Review: Intro to Networking and Cloud Computing

I recently completed a course focused on Networking and Cloud Computing, which is part of the Microsoft Cybersecurity Analyst Professional Certificate series on Coursera. This course is designed as a beginner-friendly introduction to key concepts in networking and cloud environments — and it absolutely delivers on that promise. Spread across five modules, the course covers fundamental topics like network infrastructure, monitoring, network security, cloud computing basics, virtual machines, and cloud services.

It’s especially useful for those preparing for the Microsoft SC-900 exam, which can lead to the Security, Compliance, and Identity Fundamentals Certification. I found the explanations to be clear and accessible, even for those with no prior IT experience. The course strikes a great balance between technical depth and simplicity, making it an ideal stepping stone for anyone looking to build a foundation in cybersecurity and cloud systems. Overall, it’s a valuable addition to any beginner’s learning path in tech.
