From IaaS to FaaS: An Evolutionary Analysis of Cloud Service Models

Abstract

Cloud computing has undergone a significant transformation through the development of service models, which are gradually shifting more infrastructure management responsibilities to cloud. This research examines the complete development of cloud computing services, spanning from IaaS to PaaS and FaaS. The paper demonstrates that this technological progression represents a strategic adaptation to meet the rising needs of developers for productivity and operational requirements for efficiency and business flexibility. The paper examines IaaS, PaaS, and FaaS through their essential features, benefits, and drawbacks, showing how they balance control with convenience and cost-effectiveness. The research presents a systematic evaluation that demonstrates how various models support specific design approaches and financial needs. The paper examines the key elements of containerization and microservices architecture that have enabled this technological advancement. The paper establishes that cloud-native development will succeed through the combined use of IaaS, PaaS, and FaaS within a unified system, allowing the developers to select the best solution for each application requirement.
