This document provides an overview of cloud computing. It discusses the introduction to cloud computing, tools and types of cloud computing including public, private, community and hybrid clouds. It also discusses the clients, cloud network and cloud application programming interface as tools of cloud computing. The document outlines the main services of cloud computing including Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Everything as a Service (XaaS). Finally, it discusses security and data protection in cloud computing, covering data encryption, backing up data and the Cloud Data Management Interface.

3. Cloud computing is a new and innovative technique for the
era of internet and technology. Cloud computing is a
systematic and technical way where related user can get on
demand access to the shared resources as well as
applications, servers’ storage or may any hardware device
over the internet or the network. Clients can buy the services
as per their need and requirement without getting the direct
access of hardware and User can access allocated services
and resources by using browser any where. Mostly root level
management is controlled by the vendor.
INTRODUCTION

4. Clients: A clients is a software application, platform or may be
device from where user or consumer can access their cloudy
services.
Cloud network: Cloud network is an interconnection of
resources or services between the user.
Cloud application programming interface: A cloud application
programming interface CAPI is a set of rules, tools and
that provides abstractions over a specific provider cloud.
TOOLS OF CLOUD COMPUTING

5. The public clouds: This is a general type of cloud. Normally small organization
use this type of cloud a start their system with cloud This type of cloud is highly
managed by cloud service provider.
The private cloud: This type of cloud computing infrastructure is used by single
organization and resources; services and access cannot be shared with other
organization.
The community clouds: This type of cloud can be shared among the multiple
organizations with a common tie. This type of cloud is generally managed and
controlled by a third party offering the cloud service.
The hybrid cloud: The hybrid cloud is concerned as another types of cloud
computing. In this type of cloud computing various internal or external services
provider provides service to multiple organization.
TYPES OF CLOUD COMPUTING

6. Cloud computing services provider companies or organizations are offering
range of services. According to the services module and usages it can be
categorized into four main types:
SERVICES OF CLOUD COMPUTING

7. SaaS (Software as a service)- It is an on-demand service where user or customer
pay per use of application in an independent platforming SaaS user can access
application or software as per their package anytime and anywhere by using the
browser. customer didn’t need to install the software on their PC.
PaaS (Platform as a service)- This type of service is generally used by developer
or programmers. PaaS provide environment for programming language
executional operating system, a web server and a database to the developer to
development, testing and running of their programs.
SERVICES OF CLOUD COMPUTING

8. IaaS (Infrastructure as a service)- This type of module or type offers computing
infrastructure and all computing resources including virtualization, networking
and more as well as the resources of SaaS and PaaS at a virtual environment .
type of module or type is mostly used by System administrators.
XaaS (Anything as a service) - This is a recent evolution to cloud computing
services. In XaaS, X is figure as anything which can be any cloud computing
services or as well as the mix of all resources of all three services. This module or
type is also known as ‘Everything-as-a-Service’.

9. Security is a major challenging factor with could computing and it’s data. In this
session we will shortly discuss some important mechanisms of protection can be
used for data security in cloud computing.
SECURITY & DATA PROTECTION IN CC

10. Data encryption: Data encryption is most important way to protect data from
being understood or used by unrelative users. Even if unfortunately, any
unauthorized or unrelative party got the access of the data in cloud, they con
read or use it.
Backing up the data: Backing up the data is also considered as important
mechanism in the protection of data in cloud. Backing up the data is another
better way to protect the data and backed up data also must be protected
by using encryption decryption method.
Cloud Data Management Interface: Cloud Data Management Interface (CDMI) is
a modern mechanism in the phase of protection of data in the cloud. With the
implementation of CDMI user can transferred their data securely and easily from
previous to new one vendor.
