Infrastructure-as-a-Service (IaaS)

Infrastructure as a service (IaaS) is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. In this lecture, we’ll take a look at the detail of the IaaS cloud service type.


In this lecture, you will be introduced to the foundational concept of cloud computing, specifically focusing on Infrastructure as a Service (IaaS). The session will begin with an exploration of the three main categories of cloud services: IaaS, Platform as a Service (PaaS), and Software as a Service (SaaS), which are collectively known as the computing stack.

The lecture will delve into IaaS in detail, clarifying that it provides computing resources like compute power, storage, and networking on a pay-as-you-go basis, thereby eliminating the capital and operational costs associated with maintaining on-premises data centers.

You’ll learn about the flexibility and scalability benefits of IaaS, which make it ideal for a variety of business scenarios, such as Lift-and-Shift migrations, test and development environments, storage, backup, recovery, and support for web applications. The lecture will also touch upon the utility of IaaS in high-performance computing tasks like simulations and complex problem-solving.

Towards the end, the lecturer will reinforce the key points you need to remember for exams: IaaS allows for on-demand provisioning of essential computing resources on a pay-as-you-go basis. The cloud service provider manages the infrastructure while you are responsible for managing your software stack, which includes the operating systems, middleware, and applications.

The lecture is designed to not only define IaaS but also to contextualize its use in practical business applications, enhancing your understanding of when and how to leverage IaaS solutions effectively.
