Infrastructure as a Service (IaaS) is a cloud computing model where a third-party provider supplies virtualized computing resources over the Internet. Instead of managing physical servers, storage, and networking infrastructure in-house, organizations can use IaaS to access and manage these resources through a web-based dashboard.
The IaaS model offers flexibility and scalability, allowing businesses to focus on their core operations while relying on their IaaS provider for robust, scalable infrastructure.
IaaS provides a comprehensive suite of cloud-based services, including virtual machines, storage, and networking capabilities. By outsourcing infrastructure management to an IaaS provider, organizations gain access to high-performance computing resources without the need for physical hardware.
