Infrastructure as a Service (IaaS) offers a set of core infrastructure capabilities like elastic compute and storage to provide customers the ability to run any workload in the cloud. Essentially, the cloud allows IT shops to engage in low-risk development. IaaS can be thought of as “rented hardware” that enterprises can access instantly with little upfront cost, providing them with the computing, storage, and networking functions for existing services or new projects.
Platform as a Service (PaaS) allows business users and developers to cost-effectively build, deploy, and manage application workloads seamlessly on premises or in the cloud—with superior choice, openness, security, and ease of use.
As the cloud matures, more and more enterprises are utilizing solutions such as Oracle Cloud, AWS, and Azure to launch projects in the cloud.
