Infrastructure as a service (IaaS) is a type of Cloud Computing model that provides businesses with access to computing resources, such as servers, storage, and networking, on a pay-per-use basis. IaaS providers offer these resources over the internet, allowing businesses to access and use them as needed without the need to purchase and maintain their own hardware and infrastructure.
IaaS is typically used by businesses that want to outsource the management and maintenance of their IT infrastructure to a third-party provider. This can help businesses to reduce their upfront costs and ongoing maintenance expenses, as well as to increase their flexibility and scalability.
IaaS providers typically offer a range of computing resources, including virtual machines, storage, and networking, that can be accessed and managed through a web-based interface or API. This allows businesses to quickly and easily provision and configure the resources they need, without the need to purchase and install hardware or manage infrastructure.
In addition to providing access to computing resources, IaaS providers often offer a range of additional services, such as Load Balancing, backup and recovery, and security. These services can help businesses to ensure that their applications and data are available and secure, even in the event of hardware failure or other disruptions.
Overall, IaaS is a valuable tool for businesses that want to outsource the management and maintenance of their IT infrastructure, while retaining control over their applications and data. By providing access to a wide range of computing resources on a pay-per-use basis, IaaS providers can help businesses to reduce their costs, increase their flexibility, and scale their operations more easily.
