Infrastructure as a service (IaaS) is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. IaaS is one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless.
Benefits of IaaS
Migrating your organization's infrastructure to an IaaS solution helps you reduce maintenance of on-premises data centers, save money on hardware costs, and gain real-time business insights. IaaS solutions give you the flexibility to scale your IT resources up and down with demand. They also help you quickly provision new applications and increase the reliability of your underlying infrastructure.
IaaS lets you bypass the cost and complexity of buying and managing physical servers and datacenter infrastructure. Each resource is offered as a separate service component, and you only pay for a particular resource for as long as you need it. A cloud computing service provider like Azure manages the infrastructure, while you purchase, install, configure, and manage your own software-including operating systems, middleware, and applications.
Migrating your organization's infrastructure to an IaaS solution will help you:
- reduce the maintenance of local data centers,
- save hardware costs,
- get information in real time.
- enable flexible vertical increase or decrease of the capacity of IT resources based on demand.
- they also help to quickly provision new applications and increase the reliability of the underlying infrastructure.
