What is IT infrastructure?

This episode of Techsplainers introduces IT infrastructure as the foundation of modern digital business. It explains how hardware, software and networking work together to support the systems organizations depend on every day, from servers and storage to operating systems, business applications and employee devices. The episode walks through the difference between traditional on-premises infrastructure and cloud infrastructure, highlighting how virtualization made modern cloud computing possible and helped pave the way for services like IaaS, PaaS, SaaS and hybrid cloud. It also explores why infrastructure has become a strategic business enabler, powering cloud computing, process automation, AI, generative AI and real-time analytics. Listeners will also hear how modern IT infrastructure supports innovation, improves security, and keeps evolving to support new developments in DevOps and AIOps.
