IAAS is known as Infrastructure as a service. It is one of the layers of the popular computing model. IAAS is about virtualized computing resources, such as servers, storage, and networking, over the internet . With IaaS, users can rent these resources on a pay-per-use basis, rather than having to purchase and maintain their own physical infrastructure. This allows for greater scalability, flexibility, and cost-effectiveness in managing IT resources.
Use cases for IaaS
IaaS can be used in a variety of ways, depending on the needs of the user. Some common use cases for IaaS include:
- Web hosting: IaaS can be used to host websites and web applications, providing the necessary computing resources to handle traffic and maintain uptime.
- Development and testing: IaaS can provide a cost-effective way to test and develop applications, without the need for on-premises infrastructure.
- Big data processing: IaaS can be used to process and store large amounts of data, which can be analyzed to gain insights and inform business decisions.
Features
IaaS providers typically offer a range of features and services to support their customers. Some of the key features of IaaS include:
- Virtualization: IaaS relies on virtualization technology to create virtual machines, which can be used to run applications and store data.
- On-demand scalability: With IaaS, users can quickly and easily scale their computing resources up or down as needed, based on changes in demand.
- Self-service: IaaS providers typically offer self-service portals or APIs, which allow users to provision and manage their own computing resources.
- Pay-per-use pricing: IaaS users only pay for the computing resources they use, based on an hourly or monthly rate.
