Infrastructure-as-a-Service (IaaS) is a cloud computing solution, providing complete IT infrastructure components, such as servers, networks, storage system, data center, and others, to various user groups including large and small & medium enterprises (SMEs). It reduces hardware cost by providing virtual server rooms and network systems to third-party or in-house data centers. Major IaaS solution providers, including Amazon Web Services, Inc., IBM Corporation, Microsoft Corporation, and others, improve efficiency, security, and optimize business operations for enterprises through robust virtual computing infrastructure. In addition, IT infrastructure utilization through flexible data usage and structuring virtual machines as per customer requirement augment the IaaS market growth. It enables users to scale up their hardware need with various components including network connections, load balancers, server space, and others. In the recent years, several industry verticals, such as healthcare, manufacturing, retail, automotive, telecom & IT, business service providers, and others, have adopted IaaS for better IT stability with reduced cost of infrastructure.
