Types of Cloud Computing
Cloud Computing is multiplying, resulting in it being
classified into several different categories. However, out of various
categories, there are six that stand out. These six categories are further
divided into two parts: the category of cloud-based
deployment and the category of cloud-based services.
Cloud Computing is divided into three categories based on
deployment, including:
·
Public cloud
·
Private cloudCloud Computing -
·
Hybrid cloud
The remaining three categories are divided based on the
services they offer, including:
·
Infrastructure
as a Service (IaaS)
·
Platform as a Service
(PaaS)
·
Software as a Service
(SaaS)
Now that you have a better idea of what the cloud categories
are let’s learn more about them in-depth.

Types of cloud computing
There are three main types of cloud computing service models
that you can select based on the level of control, flexibility, and management
your business needs:
·
Infrastructure as a service (IaaS) offers
on-demand access to IT infrastructure services, including compute, storage,
networking, and virtualization. It provides the highest level of control over
your IT resources and most closely resembles traditional on-premises IT
resources.
·
Platform as a service (PaaS)
offers all the hardware and software resources needed for cloud application
development. With PaaS, companies can focus fully on application development
without the burden of managing and maintaining the underlying infrastructure.
·
Software as a service (SaaS) delivers a
full application stack as a service, from underlying infrastructure to
maintenance and updates to the app software itself. A SaaS solution is often an
end-user application, where both the service and the infrastructure is managed
and maintained by the cloud service provider.

According to Wikipedia website?
Though service-oriented
architecture advocates "Everything as a service" (with the
acronyms EaaS or XaaS, or simply aas), cloud-computing
providers offer their "services" according to different models, of
which the three standard models per NIST are Infrastructure as a
Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
From <https://en.wikipedia.org/wiki/Cloud_computing>
According to IBM website?
IaaS
(Infrastructure-as-a-Service), PaaS (Platform-as-a-Service) , and SaaS
(Software-as-a-Service) are the three most common models of cloud
services, and it’s not uncommon for an organization to use all three.

Cloud model types
If we analyze the Cloud technology intelligently, we will
see that most people separate the cloud computing model into two distinct sets:
·
Deployment Model: refers to the management
of the cloud's infrastructure. The cloud hosting deployment model designates
the cloud environment's exact category, its size, and the accessing mechanism.
It also tells the nature and purpose of the cloud.
·
Service model: Cloud computing is a broad
term that holds a more extensive range of services. It is composed of a
particular type of service; a cloud computing platform allows its users to
access.

Types of cloud services: IaaS, PaaS, serverless and SaaS
Most cloud computing services fall into four broad
categories: infrastructure as a service (IaaS), platform as a service (PaaS),
serverless and software as a service (SaaS). These are sometimes called the
cloud computing stack because they build on top of one another. Knowing what
they are and how they are different makes it easier to accomplish your business
goals.
Infrastructure as a service (IaaS)
The most basic category of cloud computing services. With
IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage,
networks, operating systems—from a cloud provider on a pay-as-you-go basis.
Platform as a service (PaaS)
Platform as a service refers to cloud computing services
that supply an on-demand environment for developing, testing, delivering and
managing software applications. PaaS is designed to make it easier for
developers to quickly create web or mobile apps, without worrying about setting
up or managing the underlying infrastructure of servers, storage, network and
databases needed for development.
Serverless computing
Overlapping with PaaS, serverless computing focuses on
building app functionality without spending time continually managing the
servers and infrastructure required to do so. The cloud provider handles the
setup, capacity planning and server management for you. Serverless architectures
are highly scalable and event-driven, only using resources when a specific
function or trigger occurs.
Software as a service (SaaS)
Software as a service is a method for delivering software
applications over the Internet, on demand and typically on a subscription
basis. With SaaS, cloud providers host and manage the software application and
underlying infrastructure and handle any maintenance, like software upgrades
and security patching. Users connect to the application over the Internet,
usually with a web browser on their phone, tablet or PC.

Types of Cloud Services
Regardless of the kind of service, cloud computing services
provide users with a series of functions including:
·
Email
·
Storage, backup, and data retrieval
·
Creating and testing apps
·
Analyzing data
·
Audio and video streaming
·
Delivering software on demand
Cloud computing is still a fairly new service but is being
used by a number of different organizations from big corporations to small
businesses, nonprofits to government agencies, and even individual consumers.

Types of Cloud Computing
Cloud computing is not a single piece of technology like a
microchip or a cellphone. Rather, it's a system primarily comprised of three
services: software-as-a-service (SaaS),
infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).
1.
Software-as-a-service (SaaS) involves the
licensure of a software application to customers. Licenses are typically
provided through a pay-as-you-go model or on-demand. This type of system can be
found in Microsoft Office's 365.1
2.
Infrastructure-as-a-service (IaaS) involves
a method for delivering everything from operating systems to servers and
storage through IP-based connectivity as part of an on-demand service. Clients
can avoid the need to purchase software or servers, and instead procure these
resources in an outsourced,
on-demand service. Popular examples of the IaaS system include IBM Cloud and
Microsoft Azure.12
3.
Platform-as-a-service (PaaS) is considered
the most complex of the three layers of cloud-based computing. PaaS shares some
similarities with SaaS, the primary difference being that instead of delivering
software online, it is actually a platform for creating software that is
delivered via the Internet. This model includes platforms like Salesforce.com
and Heroku.

What Are the Main Types of Cloud Computing?
The main types of cloud computing services include
Infrastructure-as-a-Service (IaaS), Platforms-as-a-Service (PaaS), and
Software-as-a-Service (SaaS).10
·
IaaS provides IT infrastructure to
end-users via the internet and is commonly associated with serverless
computing.
·
PaaS serves both software and hardware to
end-users, who are generally software developers. PaaS allows the user to
develop, run, and manage their own apps without having to build and maintain
the infrastructure.
·
SaaS is a software licensing model, which
allows access to software on a subscription basis using external servers
without having to download and install them locally.
