Infrastructure-as-a-Service (IaaS) is a cloud-computing offering in which a vendor provides users access to computing resources such as servers, storage and networking. Organizations use their own platforms and applications within a service provider’s infrastructure.
Instead of purchasing hardware outright, users pay for IaaS on demand.
Infrastructure is scalable depending on processing and storage needs.
Saves enterprises the costs of buying and maintaining their own hardware.
Because data is on the cloud, there can be no single point of failure.
Enables the virtualization of administrative tasks, freeing up time for other work.
Platform as a service (PaaS) is a cloud computing offering that provides users with a cloud environment in which they can develop, manage and deliver applications. In addition to storage and other computing resources, users are able to use a suite of prebuilt tools to develop, customize and test their own applications.
PaaS provides a platform with tools to test, develop and host applications in the same environment.
Enables organizations to focus on development without having to worry about underlying infrastructure.
Providers manage security, operating systems, server software and backups.
Facilitates collaborative work even if teams work remotely.
