IaaS allows companies to rent basic computing, storage and networking resources on demand and pay only for what you need. This service allows you to reduce your IT infrastructure and hardware maintenance costs.
A cloud provider, such as Microsoft Azure, manages the IT infrastructure for you, while you’re still responsible for purchasing, installing, configuring, and managing your own software, operating systems, middleware, and applications.
IaaS benefits include optimized costs and improved scalability, performance, stability, reliability, security, and disaster recovery.
