Infrastructure as a Service (IaaS) is a cloud computing model where a third-party provider hosts and maintains the underlying infrastructure, including servers, storage, and networking resources, and provides them to customers as a service over the internet. Customers can rent these resources on-demand and pay for them on a pay-as-you-go basis.
Some examples of IaaS providers include:
- Amazon Web Services (AWS): One of the most popular IaaS providers, AWS offers a wide range of cloud computing services, including EC2 (Elastic Compute Cloud), which provides scalable compute capacity in the cloud, and S3 (Simple Storage Service), which provides scalable object storage for data.
- Microsoft Azure: Another leading IaaS provider, Azure offers a range of cloud computing services, including Virtual Machines, which provide scalable compute capacity in the cloud, and Blob Storage, which provides scalable object storage for data.
- Google Cloud Platform: Google Cloud Platform offers a range of IaaS services, including Compute Engine, which provides scalable compute capacity in the cloud, and Cloud Storage, which provides scalable object storage for data.
- DigitalOcean: DigitalOcean is a smaller IaaS provider that focuses on simplicity and ease of use. They offer a range of cloud computing services, including Droplets, which provide scalable compute capacity in the cloud, and Spaces, which provide scalable object storage for data.
IaaS is a popular cloud computing model for organizations that want to outsource their IT infrastructure and focus on their core business. It allows organizations to quickly provision and scale resources as needed, without the overhead of managing physical infrastructure.
