The core components of IaaS generally include virtualized compute resources (virtual machines or VMs), storage (both block and object storage), networking (virtual networks, load balancers, firewalls), and operating systems. These components are provisioned and managed through a self-service portal or API, giving users considerable control over their infrastructure. Users can scale these resources up or down as needed, adapting to fluctuating demands and optimizing costs.

Additional services often offered include databases, monitoring tools, and security features.

Provider and User Responsibilities in IaaS

In an IaaS model, responsibilities are clearly divided between the provider and the user. The provider is responsible for the underlying physical infrastructure—the servers, networking equipment, data centers, and power—as well as the virtualization layer that allows for the creation and management of virtual machines. They also manage the underlying operating system of the physical infrastructure. The provider ensures the availability and security of this infrastructure, typically offering Service Level Agreements (SLAs) guaranteeing uptime and performance.The user, on the other hand, is responsible for managing the operating systems, applications, databases, and other software running on the virtual machines.

They are also responsible for configuring the network, security, and data management aspects within their virtualized environment. This includes tasks such as patching operating systems, installing and configuring applications, and backing up data. Essentially, the user manages everything “above” the virtualized infrastructure layer.
