Infrastructure as a Service (IaaS)
IaaS is a cloud computing service model that provides virtualized computing resources over the internet.
Description
Infrastructure as a Service (IaaS) is a cloud computing service model that delivers virtualized computing infrastructure over the internet. In the context of AWS (Amazon Web Services), IaaS enables businesses to rent IT infrastructure, such as servers, storage, and networking resources, on a pay-as-you-go basis. This allows organizations to avoid the upfront costs and complexity of owning and managing physical servers. AWS offers a range of IaaS products, such as Amazon EC2 (Elastic Compute Cloud), which allows users to launch and manage virtual servers, and Amazon S3 (Simple Storage Service), which provides scalable storage solutions. Businesses can quickly scale their infrastructure up or down based on demand, providing flexibility and efficiency in resource utilization. Additionally, IaaS supports various operating systems and applications, enabling developers to create and deploy software without worrying about the underlying hardware. This model is particularly beneficial for startups and enterprises alike, as it reduces the burden of hardware management while allowing for innovation and agility in deployment.
Examples
- Amazon EC2: A service that provides resizable compute capacity in the cloud, allowing users to run virtual machines with various operating systems.
- Amazon S3: A scalable object storage service that allows users to store and retrieve any amount of data at any time from anywhere on the web.
Additional Information
- IaaS offers benefits like high availability, disaster recovery, and automated backups, which are essential for business continuity.
- Users can benefit from AWS's global infrastructure, ensuring low-latency access and redundancy across multiple geographical locations.
