Abstract
Cloud computing represents a major shift in information systems architecture, combining both
new deployment models and new business models. Rapid provisioning, elastic scaling, and
metered usage are essential characteristics of cloud services, and they require cloud resources
with these same characteristics. Cloud offers various services to the customers starting from
SaaS (Software-as-a-Service), PaaS(Platform-as-a-Service), IaaS (Infrastructure-as-a-Service)
and FaaS(Function-as-a-Service). This paper prepared on researching various cloud services on
the internet.

Introduction
Cloud computing is a general term for the delivery of hosted services over the internet.
Cloud computing enables companies to consume a compute resource, such as a virtual machine
(VM), storage or an application, as a utility just like electricity rather than having to build and
maintain computing infrastructures in house (Rouse, 2012). Cloud computing is the delivery of
on-demand computing services from applications to storage and processing power typically over
the internet and on a pay-as-you-go basis. A fundamental concept behind cloud computing is that
the location of the service, and many of the details such as the hardware or operating system on
which it is running, are largely irrelevant to the user. It's with this in mind that the metaphor of
the cloud was borrowed from old telecoms network schematics, in which the public telephone
network (and later the internet) was often represented as a cloud to denote that the underlying
technologies were irrelevant (Ranger, 2018).
Cloud Characteristics
To employ new technology like cloud, organizations must understand what exactly they
are getting and various characteristics of it. Following are four essential characteristics of the
cloud:
On-Demand Self Service: A consumer can unilaterally provision computing capabilities, such
as server time and network storage, as needed automatically without requiring human interaction
with each service provider.
Broad Network Access : Capabilities are available over the network and accessed through
standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g.,
mobile phones, tablets, laptops and workstations).

Resource Pooling : The provider's computing resources are pooled to serve multiple consumers
using a multi-tenant model, with different physical and virtual resources dynamically assigned
and reassigned according to consumer demand. There is a sense of location independence in that
the customer generally has no control or knowledge over the exact location of the provided
resources but may be able to specify location at a higher level of abstraction. Examples of
