IaaS Architecture
IaaS (Infrastructure as a Service) Architecture is a cloud computing model where virtualized computing resources—such as servers, storage, and networking—are provided over the internet on a pay-as-you-go basis. It enables organizations to outsource their physical infrastructure to cloud providers, allowing them to scale resources dynamically without managing hardware. This architecture forms the foundation for building and deploying applications in a flexible, cost-effective manner.
Developers should learn IaaS Architecture when building scalable applications that require on-demand infrastructure, such as web hosting, big data processing, or disaster recovery solutions. It is particularly useful for startups and enterprises needing to avoid upfront capital expenditure on hardware while maintaining control over operating systems and applications. Understanding IaaS helps in designing resilient systems that can handle variable workloads efficiently.
