3 Types of Cloud Services Introduction

1
Cloud computing has three most common types of
cloud services to offer. Depending on the needs
of users, any type of cloud computing service is
used either individually or in combination with
others. The following is a brief introduction to
the three cloud service types, namely, SaaS,
PaaS and IaaS.

• Software as a service (SaaS)

SaaS is also known as on-demand software. Users
of SaaS rather than fully buy the license of
various software hire the software at regular
intervals and use it through an Internet
browser. The variety of software provided by SaaS
is very broad. There are a number of software
used by SaaS from companies such as ezTalks Video
Conferencing that employs in content management,
human resources management, accounting, ERP,
customer relationship management and other
relevant areas. The software-as-a-service type
of cloud computing grows very quickly, while the
largest market for software-as-a-service
electricity is customer relationship
management. In this service model, the
cloud-based applications are offered to the
customer as a service on request. It is a single
instance of the service running on remote
computers in the cloud, owned and operated by
others, and connected to the users' computers
over the Internet and typically a web browser.
Social networking sites like Facebook, Twitter,
Flickr and Google are all examples of SaaS,
although users are able to access the services
through any Internet-enabled device.

• Platform as a service (PaaS)

PaaS provides computers platforms for users of
cloud computing. It is also the link between the
other two services provided by cloud computing
SaaS and IaaS. A normal computer requires a
computer platform that contains hardware
architecture along with a framework of software.
Such a platform is the basis of the collaboration
of hardware and software, which includes the
operating system of the operating system,
architecture and languages. When it comes to
cloud computing, in the absence of a real
computer, it is platform as a service that
provides users with everything that is required
to compose a computing platform. Some of the
facilities that PaaS provides include hosting,
implementation, test and application
development, and application design. In addition,
cloud service providers that offer PaaS include
a set of features to design, test, implement,
manage, and run applications. All these
facilities can be used by both individual and
business customers, by subscribing to a single
package with all the features offered. The
platform-as-a-service (PaaS) model is a level
above the software as a service setup and
provides hardware, network and operating system
so that a customer can design their own
application and software. In order to meet the
requirements of applications such as scalability
and manageability, a predefined combination of
operating system OS and application servers from
PaaS vendors. For example, at any stage of the
process to develop, test and ultimately host
their sites, Web developers can use individual
PaaS environments.

• Infrastructure as a Service (IaaS)

IaaS is the third type of computing across the
cloud. Just like PaaS and SaaS,
different software and hardware devices deliver
on a cloud platform, while IaaS provides a
virtualized platform. The process of hardware
virtualization shows the users only the abstract
computing platform instead of the physical
functions. Such virtualization results
3
in the creation of a so-called "virtual machine
monitor" or "hypervisor", which is the creation
of the third part of the cloud computing, i.
Interface as a service. Infrastructure available
to users of Interface as a Service includes
software, servers, network devices, and data
center space. The cost incurred by customers'
cloud service providers typically depend on the
amount of activity performed by the user and is
therefore not set. However, there is a minimal
amount of charge depending on the number of
facilities that a user has subscribed
to. Infrastructure-as-a-Service (IaaS) is a
basic computing and storage space provided by a
standardized service over the network. This model
has made the workload easier by consolidating
and providing data center space, storage systems,
network devices, servers, and so on. In
addition, the customer can develop and install
their own operating systems, software and
applications. There are a number of advantages
of using cloud computer technology. However, any
type of cloud service comes with its own set of
advantages and disadvantages. In order to make
the right decision, it is imperative that users
carefully weigh the pros and cons. https//www.ez
