Cloud Computing Power Point Presentation 2022

Cloud Computing

Introduction
What is Cloud Computing?
It is a concept, that has been provided by the ICT (Information and
Communications Technology).
The operation of cloud computing is quite similar to that of web-based email
clients, which allows the user with the access permissions without asking much
for the hardware requirements.
Elasticity and resource pooling are some of its prime features.
This also serves a large number of clients with the same amount of resources

Key characteristics:
Improving the organizational agility by increasing user flexibility,
expanding or adding technological resources.
Cloud providers often claim cost reductions.
Independent in terms of device and location.
The cloud computing applications are comparatively easier to maintain
since they can be accessed from anywhere irrespective of the devices and
locations used.
Multitenancy is another prime characteristic that is provided by cloud
computing.
Enhanced productivity

Key concepts:
The uploaded information can be accessed remotely.
The companies providing cloud services to their clients, allows the users
to remotely store their applications and files.
These applications and files can later be accessed with the help 0f
internet.
Therefore, there is no need to carry personal devices as the files can be
accessed remotely.
All the computer related clustered tasks is moved to the cyber space
with the help of cloud computing.

Major cloud computing types:
Private Cloud- The resources are deployed for a particular organization.
Community Cloud- Specified organizations and communities are
responsible for accessing the resources.
Public Cloud- Government, business or academic organizations govern and
own the resources.
Hybrid Cloud- It can be used in B2C as well as B2B interactions. The
resources here are bounded by several clouds.

Cloud Computing Architecture:
In a cloud, there is always a front and a back end.
The front end comprises of the client part such as specified
applications and interfaces for the purpose of accessing the cloud
platform.
The back end comprises of the cloud itself which includes all the
resources that are required for the purpose of cloud computing
services.
The back end generally comprises of servers, virtual machines,
security mechanisms, data storage etc.

The concept of Virtualization:
It can be stated as the enabling technology for cloud computing services.
A single physical server can be partitioned into various logical servers with
the help of virtualization.
After the partition, each logical server acts as an individual physical server
and can independently run the applications along with an operating system as
well.
Virtualization is provided by many famous companies like Microsoft and
VMware.
In such cases, the company provides their clients to use their dedicated virtual
servers to store the data rather than storing them in the personalized system.

Key Purposes of
Virtualization:
In general, there are three prime purposes of virtualization. They are as
follows:
Network virtualization
Storage virtualization
Server virtualization

Why Cloud Computing?
Cloud computing is a huge shift from the traditional way of perceiving IT
resources. Few of the core reasons, as to why VideoDev Ltd. should move to
cloud computing platform have been mentioned below:
Cost
Speed

Characteristics of PaaS:
The concepts of PaaS is solely built on the process of
virtualization technology, signifying the possibility to scale
resources depending upon the business changes.
A wide range of services is provided by PaaS for the purpose
of assisting testing, deployment as well as development of
the apps.
Several users can access the development application at the
same time.
Integration of databases and web services.

Characteristics of IaaS:
Availability of the resources is on the basis of service.
High scalability of the services.
On the basis of the consumption, the price varies.
The clients have complete control over their
infrastructure.
Flexible and dynamic in nature.
A single piece of hardware is included to be operated
by multiple users

Differences between PaaS and
IaaS:
PaaS
PaaS stands for Platform as a
service.
Delivering a solution stack or
a computing platform is the
prime focus of the service
providers.
 In general, application
developers are the ones who
use PaaS.
IaaS
IaaS stands for infrastructure
as a service.
 Delivering computer
infrastructures, such as the
comprised resources of a
hardware is the prime focus of
the service providers.
In general, network architects
are the ones who use IaaS.

Recommended service model
for VideoDev Ltd.-
IaaSAdvantages
One of the most flexible cloud computing models is IaaS.
The scalability of this model is very high.
Clients have complete control over their infrastructures.
Consumption based hardware purchasing is done.
Only the resources that are immensely needed are
purchased.
Deploying storage, servers, networking and processing
power in an automated manner.

Limitations of IaaS:
Although an IaaS is one of the best service models in the field of cloud
computing, it has it’s potential threats and vulnerabilities associated
with it. These are as follows:
Security issues
Operation of Legacy Systems in the cloud
Internal training and resources
Multitenant security

Deploying other architectural
pattern:
The architecture and patterns of a software generally refers to the
fundamental structures comprising a system of software. Moreover, it
also involved some disciplines for creating these patterns and
structures. An additional architectural pattern that can be deployed is:
Data centric architecture

Data-Centric Architecture:
Using a general purpose relational system for the management of the
database.
Using table driven logic, dynamic in nature
Using the stored procedures running on the servers of the database.
Using a mutual database for the purpose of hosting a communication
between the computing applications (distributed) and parallel
processes.
An overall architecture of the enterprise

Implications of data centric
architecture:
Data integrity
Restore and backup features
Providing enhanced reusability and scalability
Reducing transient data overhead within the software components.

Standard Desktop Operating
Environment (SDOE)
A Standard Desktop Operating Environment describes a computer OS
(operating system) along with software and hardware applications.
SDOE is used to deploy the custom configuration of an organization.
