Infrastructure as a Service (IaaS): A Practical Overview
Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. Instead of purchasing and maintaining physical servers, storage systems, and networking hardware, organizations can access these foundational IT resources on demand through cloud platforms. IaaS forms the base layer of cloud computing, supporting higher-level services such as Platform as a Service (PaaS) and Software as a Service (SaaS).
Core Components of IaaS
At its foundation, IaaS consists of three primary components: compute, storage, and networking. Compute resources typically include virtual machines or containers that run operating systems and applications. Storage may be offered as block storage, object storage, or file storage, allowing users to store and retrieve data based on performance and access needs. Networking capabilities include virtual networks, load balancers, firewalls, and IP address management, enabling secure and scalable connectivity between resources.
