IaaS (Infrastructure as a Service)

IaaS stands for Infrastructure as a Service — a form of cloud computing that provides virtualized computing resources over the internet. Instead of buying and managing physical servers and hardware, businesses can rent these resources on demand from cloud providers.

🔧 What is IaaS?

IaaS delivers fundamental IT resources such as:

• Servers (virtual or physical)

• Storage

• Networking

• Operating Systems

These services are typically billed on a pay-as-you-go model, meaning you only pay for what you use.

🧱 Components of IaaS:

🌐 Examples of IaaS Providers:

• Amazon Web Services (AWS EC2)

• Microsoft Azure

• Google Cloud Platform (GCP)

• IBM Cloud

• Oracle Cloud Infrastructure

✅ Benefits of IaaS:

• Scalability: Instantly add or remove resources based on demand.

• Cost-efficiency: No need to invest in expensive hardware or maintenance.

• Flexibility: Use any operating system or app environment you need.

• Business continuity: Built-in disaster recovery and backup services.

• Global reach: Deploy infrastructure anywhere in the world.

🔄 IaaS vs. Other Cloud Models:

🧠 Use Cases:

• Hosting websites and web apps

• Running big data applications

• Creating development and test environments

• Backup and recovery systems

• High-performance computing (HPC)

🚀 Summary:

IaaS gives organizations the power and flexibility of modern IT infrastructure — without the complexity of buying and maintaining physical servers. Whether you're a startup launching an app or a large enterprise scaling operations globally, IaaS can be the foundation of your digital presence.
