Infrastructure as a service (IaaS) is a form of cloud computing that delivers on-demand IT infrastructure resources such as servers, virtual machines (VMs), compute, network and storage to consumers over the internet and on a pay-as-you-go basis.

You can use IaaS to scale your compute capacity while reducing your IT expenditure. Traditionally, enterprises purchased and maintained their own computing devices in an on-premises data center. However, this often required a heavy up-front investment to handle only occasionally high workloads.

What is Virtualization?

Virtualization is a technology that you can use to create virtual representations of servers, storage, networks, and other physical machines. Virtualization softwares mimics the functions of physical hardware to run multiple virtual machines simultaneously on a single physical machine. Businesses utilise virtualization to use their hardware resources efficiently and get greater returns from their investment. It also powers cloud computing services that help organizations manage infrastructure more efficiently.

Cloud deployment defines where your cloud infrastructure is hosted and how it is managed, while Cloud services define what type of functionality you’re consuming.

Choosing a cloud deployment model and service model is a basic, but necessary, part of cloud adoption.

It’s important to know the advantages and limitations of different types of cloud computing so you can understand how they will impact your business.

If you’re curious about the world of cloud engineering — whether you’re a beginner or a tech pro — you’re in the right place. In today’s episode, we’re starting with the basics: What exactly is the cloud? You’ve probably heard people say “It’s in the cloud,” but what does that mean?
