Scalable Architectures in Distributed Cloud Systems Distributed and cloud computing systems consist of numerous autonomous computer nodes, enabling the construction of massive networks with millions connected to edge infrastructures. These scalable systems can achieve web-scale connectivity through various configurations like clusters or peer-to-peer (P2P) networks. They utilize high-speed interconnections for resource sharing among heterogeneous components, allowing dynamic provisioning and management across a virtualized environment.
Service Models Transforming Computing Efficiency Cloud computing offers three primary service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides users with essential infrastructure resources without managing underlying hardware; PaaS allows deployment of user-built applications on integrated platforms; SaaS delivers software applications via browsers without upfront investments from users. This model enhances efficiency by reducing costs associated with traditional hosting while offering flexibility in application development.
