IaaS

- Overview

Infrastructure as a Service (IaaS) is a cloud computing model providing on-demand servers, storage, and networking over the internet. It replaces physical hardware with virtual resources hosted in remote data centers. 

Infrastructure as a Service (IaaS) is a cloud computing model that lets you rent servers, storage, and networking over the internet on a pay-as-you-go basis. It removes the need to buy and fix physical computer parts. 

Infrastructure as a service (IaaS) is when a provider manages your infrastructure - the actual servers, networking, virtualization, and storage - for you, either through a public or private cloud. You access the infrastructure through an API or dashboard, and the infrastructure is leased. 

You manage things like operating systems, applications, and middleware, while providers like AWS or Microsoft Azure provide the hardware, networking, hard drives, storage, and servers—they take care of outages, repairs, and hardware issues.

Major platforms include Amazon Web Services, Microsoft Azure, and Google Cloud. 

1. Core Components:

• Compute: Virtual machines and CPU power.
• Storage: Hard drive space and data backups.
• Networking: Firewalls, routers, and IP addresses. 

2. Core Features and Working:

• Virtualization: Replaces physical computers and cables with virtual machines and software networks.
• Access: Uses a web dashboard or an application programming interface (API) to manage settings.
• Pay-as-You-Go: Charges only for the exact amount of computer power or storage space you use.

3. Main Benefits:

• Cost savings: Removes the high upfront price of buying and fixing real hardware.
• Fast scaling: Lets you grow or shrink your system size instantly based on current needs.
• No maintenance: Frees your team from physical upkeep inside a server room.
