Infrastructure as a Service

In this lesson, you will learn about Infrastructure as a Service (IaaS), the most flexible category of cloud services. IaaS provides you with the maximum amount of control over your cloud resources, allowing you to manage and configure them according to your needs.

What is IaaS?

Infrastructure as a Service (IaaS) allows you to rent hardware in a cloud datacenter. The cloud provider is responsible for maintaining the hardware, network connectivity, and physical security. You, as the user, are responsible for everything else, including:

• Operating System : Installation, configuration, and maintenance.
• Network Configuration : Setting up and managing your network.
• Database and Storage Configuration : Managing databases and storage solutions.

IaaS gives you the flexibility to run your own applications and manage your own data, providing a high level of control over your IT infrastructure.

Shared Responsibility Model

The shared responsibility model outlines the division of responsibilities between the cloud provider and the user for all cloud service types. In the IaaS model, the largest share of responsibility lies with you. The cloud provider maintains the physical infrastructure and ensures its connectivity to the internet, while you handle the installation, configuration, patching, updates, and security of your applications and data.

Scenarios for IaaS

IaaS is suitable for several common scenarios:

• Lift-and-Shift Migration : This approach involves setting up cloud resources similar to your on-premises datacenter and migrating your existing applications and data to the cloud without significant changes.
• Testing and Development : IaaS is ideal for creating and managing development and test environments. You can quickly repl…
