What is IaaS?
Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. It offers on-demand access to servers, storage, networking, and other infrastructure components, eliminating the need for businesses to maintain physical hardware.
Key Features of IaaS:
- Scalable computing resources (VMs, storage, networking).
- Pay-as-you-go pricing (cost-effective).
- Fully managed infrastructure by cloud providers.
- Flexibility to deploy and manage workloads as needed.
Leading IaaS Providers & Services
- Amazon Web Services (AWS) – EC2, S3, VPC, EBS.
- Microsoft Azure – Virtual Machines, Blob Storage, Virtual Network.
- Google Cloud Platform (GCP) – Compute Engine, Cloud Storage, VPC.
- IBM Cloud – Virtual Servers, Object Storage, Kubernetes Service.
- Oracle Cloud – Compute, Storage, Networking
Advantages of IaaS
- Cost Efficiency – No need to buy & maintain physical hardware.
- Scalability – Easily scale resources up or down as needed.
