IaaS Cloud Services

Definition and Core Concepts

Infrastructure as a Service (IaaS) is a cloud computing model that delivers virtualized computing resources—such as servers, storage, and networking—over the internet. Unlike traditional on-premises infrastructure, IaaS eliminates the need for businesses to invest in and maintain physical hardware. Instead, organizations can access and manage these resources on-demand through a cloud provider's platform.

Key components of IaaS include:

• Virtual Machines (VMs): Virtualized servers that can be configured to meet specific computing needs.
• Storage Solutions: Scalable storage options, including block storage, object storage, and file storage.
• Networking: Virtual networks, load balancers, and IP addresses to ensure seamless connectivity.
• Management Tools: Dashboards and APIs for monitoring, provisioning, and scaling resources.

IaaS is characterized by its pay-as-you-go pricing model, which allows businesses to pay only for the resources they use, making it a cost-effective solution for organizations of all sizes.
