Infrastructure as a Service (IaaS)

In the next block, we’ll delve into Infrastructure as a Service (IaaS).

It’s a foundational component of remote work. IaaS revolutionizes how businesses get and manage their infrastructure.

We will focus on cloud service models:

  • Core concepts and features.
  • Its way of empowering organizations to scale their resources.
  • The benefits in terms of cost efficiency and flexibility.

What Is IaaS?

It’s a remote model that provides virtualized resources over the internet. In essence, IaaS offers the fundamental building blocks for IT infrastructure. It includes servers, storage, networking, and virtualization. Instead of buying physical hardware, users rent resources from a remote provider.

IaaS gives organizations the flexibility to scale resources up or down as needed. It reduces the cost and complexity of maintaining in-house infrastructure. This cloud service model allows businesses to focus on their core competencies and applications. While it’s leaving the infrastructure management to the provider.

Key Features of IaaS


  • Scalability. Users can quickly add or remove resources. It’s to meet the changing demands of their applications.
  • Resource Virtualization. Resources in IaaS are abstracted from physical hardware. Users can request and configure virtual machines, storage, and networking components.
  • Self-Service. Users can provision and manage resources through a web-based interface or API. It gives them control and agility.
  • Pay-as-You-Go. This example of cloud computing is typically billed on a consumption basis. It means users only pay for the resources they use.
  • Security. IaaS providers typically offer security features like firewalls, encryption, and access controls. It’s to protect data and applications.
  • Global Reach. It allows deploying resources closer to their target audience for better performance.

Examples of IaaS Providers


  • Amazon Web Services (AWS). AWS offers a wide range of remote platforms. It includes virtual machines, storage, and databases.
