Cloud IaaS and PaaS Infrastructure Introduction Background. Delivering a new application can now be accomplished within a web browser, either using a point-and-click interface or by deploying custom code. This chapter has focused on many concepts that will be important in the rest of the book. This concept is operationalized in cloud computing through several service models as defined by the National Institute of Standards and Technology (NIST). IaaS is one of the four types of cloud services, along with software as a service ( SaaS ), platform as a service ( PaaS ), and serverless. The leading service in the cloud computing industry is SaaS with a 39. IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems. Follow the PaaS Considerations checklist. Besides SaaS, there are two more cloud computing models: PaaS and IaaS. NIST has also published a cloud computing reference architecture4. (Software as a Service). PaaS is at the middle of the stack between IaaS and software as a service (SaaS). The SPI model refers to the most common service models of cloud computing: software as a service (SaaS), platform as a service ( PaaS) and infrastructure as a service ( IaaS ). PaaS. Instead, concentrate on managing the key generic issue underlying it:… Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) and give some examples and case studies to illustrate how they all work. Cloud computing has become a staple in business strategy and IT architecture over the past years. Abstract.
