Software-as-a-Service (SaaS):
SaaS applications are hosted on cloud servers and accessed via the Internet rather than being installed on the user’s device. SaaS is similar to renting a home: the landlord takes care of the property, while the renter gets to utilize it as if it were their own. Salesforce, MailChimp, and Slack are examples of SaaS apps.
Platform-as-a-Service (PaaS):
Companies don’t pay for hosted applications under this model; instead, they pay for the components they need to develop their own apps. PaaS companies provide everything needed to construct an application via the Internet, including development tools, infrastructure, and operating systems. PaaS is comparable to renting all of the tools and equipment needed to build a house rather than the house itself. Heroku and Microsoft Azure are two instances of PaaS.
Infrastructure-as-a-Service (IaaS):
A corporation rents the servers and storage it requires from a cloud provider in this approach. They then construct their applications on top of that cloud architecture. IaaS is similar to a firm renting a piece of land on which they can construct whatever they want, but they must provide their own construction equipment and supplies. DigitalOcean, Google Compute Engine, and OpenStack are examples of IaaS providers.
Did you know? that GBCloud is also IaaS, it provides virtualized computing resources over the internet. This includes virtual servers, storage, and networking services. Users can rent these resources on a pay-as-you-go basis, allowing for scalability and flexibility in managing infrastructure without the need to invest in physical hardware.

Previously, the three primary paradigms of cloud computing were SaaS, PaaS, and IaaS, and almost all cloud services fell into one of these categories. In recent years, however, a fourth model has emerged:
Function-as-a-Service (FaaS):
FaaS, also known as serverless computing, divides cloud applications into smaller components that run only when they’re needed. Imagine being able to rent a house in small increments: for example, the tenant only pays for the dining room when they are eating, the bedroom when they are sleeping, and the living room when they are watching TV, and they do not have to pay rent on those rooms when they are not in use.
All of these cloud computing paradigms, including FaaS or serverless applications, nevertheless run on servers. However, they are referred to as “serverless” because they do not run on dedicated machines and the company who create them do not have to manage any servers.
Also, when more people use the app, serverless functionalities scale up, or replicate – imagine if the tenant’s dining room could expand on demand as more people came over for dinner!
