According to 451 Research, 90 percent of enterprises are on the cloud. Cloud computing offers various benefits, including cost-effectiveness, daily backups, unparalleled mobility,  extreme reliability, easy scalability, and better security. Within the cloud computing umbrella, there are three main types of cloud computing: Software-as-a-service (SaaS), Infrastructure-as-a-service (IaaS), and Platform-as-a-Service (PaaS). Let’s discuss each type.

Infrastructure-as-a-Service (IaaS)

IaaS provides organizations with the essential computer, network, and storage resources over the internet on a pay-as-you-go basis. For this type, cloud vendors host the infrastructure components, such as networks, storage, and servers. Enterprises opt for IaaS to avoid the costs of establishing on-site data centre infrastructure.

Platform-as-a-Service (PaaS)

Through PaaS, organizations rent everything needed to develop applications from a cloud provider, such as infrastructure, development tools, and database management systems. This is useful for organizations to avoid the costly and difficult process of purchasing software licenses. This also allows the developers to focus on the application they are building rather than on the backend components.

Software-as-a-Service (SaaS)

SaaS providers host software that organizations can rent and distribute to their employees. Rather than downloading the software on each computer, employees can access the software through their web browser using their usernames and passwords. As long as the user has internet connectivity, they can access their software. The software provider manages the software and hardware and keeps it secure. SaaS, therefore, allows businesses to access applications quickly and at minimal costs.

Which Type Is Right For Your Business?

The right cloud-computing configuration depends on each business’s needs. Furthermore, a combination of the models may be appropriate for the organization.
