What is IaaS Cloud Computing?

IaaS - Infrastructure as a Service, is a cloud computing solution that offers infrastructure including virtualized storage, servers and networking resources on a pay-as-you-go basis.

By deploying the IaaS cloud computing solutions, enterprises can operate the systems and applications on the third-party servers instead of their owned on-premises IT infrastructures.

In a nutshell, IaaS cloud computing has revolutionized the traditional hardware-oriented practices, allowing enterprises to scale up or down in a much more flexible manner.

What is SaaS Cloud Solution?

SaaS - Software as a Service, which will deliver software and applications over the internet via a subscription model.

With SaaS Cloud Solutions, enterprises no longer need to install, upgrade and manage software applications on their local services or computers as everything runs solely on the SaaS providers' servers.

SaaS cloud solutions allow enterprises to get rid of the complicated software and hardware management given that the only requirement is a stable internet connection.
