Introduction
Cloud computing is simple on demand available computer resource data management and
computing power active management for the user. This term is simply used to describing the data
center which is available for the entire user. In cloud computing, various types of services are
also offered like database, server, and other functions. Cloud computing is simply used as a
metaphor for the internet. It is also used to maintain data and applications.
Dotcom company is simply a multinational company which issued for managing the data by
using remote desktop and for this it is not an efficient way to solve this problem (data handling),
and the major problem of this is that remote desktop client doesn’t allow the user to work at
different location and devices.
Solution for this data handling problem is using cloud computing techniques in it which helps the
data for smooth flow and a user can use the data at different location & device.

LO1 Demonstrate an understanding of the fundamentals of Cloud Computing
and its architectures
P1 Analyse the evolution and fundamental concepts of Cloud Computing.
Cloud computing technology was developed in 1960 and which is developed by Carl and
Licklider. There are 3 phases present in cloud computing. The first phase is simple to use for the
evolution of computing and as well as grid computing, and it was developed in 1960. The second
phase is related to the pre-cloud phase, and it uses the help of the internet, and it was developed
in 1999 and lasted 2006. The third phase is simply related to real techniques like IaaS, SaaS,
PaaS, which is developed in 2007.
In cloud computing there is 2 type of block front end, and back end is connected via the internet,
and the work which is done by front end and backend is the front end is used to interact client
with the system, and backend is used to provide various services in it like data storage and
servers. There is also various kind of layer application files also present in cloud computing
(Simplilearn.com, 2019).

P2 Design an appropriate architectural framework Cloud Computing for a given
scenario
Architecture framework of cloud computing consists of various things which also include multi-
cloud. In cloud computing there is single “All-in-One” is used, in this server various server
templates which contain web server, PHP.
Figure 1: Basic Architecture of cloud computing
(Source: tutorialspoint, 2019)
There are various types of architecture present in cloud computing:
 Single Cloud Site Architecture
 Multi-Datacenter Architecture
 Auto-scaling Architecture
7 | P a g e

These are the most commonly used architecture:
Single Cloud Site Architecture: In this type of architecture 3-tier website architecture is
present which include at least one server in it, in this architecture, it is further divided into 2
parts:
Figure 2: Single cloud architecture
(Source: Docs.rightscale, 2019)
Non-reductant 3 tier architecture: It is used if a user only wants to interact and test the
architecture; this system is also used to save cost and resources which are using in it, so the basic
purpose of this architecture is to test and development (Docs.rightscale, 2019)

(Source: Docs.rightscale, 2019)

2. Reductant 3-Tier Architecture: This type of architecture model is used for recovery and
failover purpose. In this, we use the server to the application for the autoscaling in the cloud
Figure 4: Reductant 3 tier architecture
(Source: Docs.rightscale, 2019)
Multi-Datacenter Architecture: It is used to support multiple zones at a single time of period,
in this, there is another kind of layer also add just for redundancy and protection, these zones are
used when power error occurs then it is used to protect and save the given data.

Auto-scaling Architecture: It is used as the ability of scale which we are using in it; this type of
architecture is simply used for the applications which simply refer to the cloud.

M1 Discuss why an organization should migrate to a Cloud Computing solution
Cloud computing has several numbers of advantages which are present in various industrial
purposes which is used to led the uses of this in further process. The basic and primary reason of
migration is basically used to allow all the organization to use the software which is related to
cloud computing from any place by just using internet services and server of it because migration
consists a safe and secure way to use the information and data which e are using in it. In this
process, user cannot depend on the location and complete that task at any time period, due to it is
location independent so a user can do work at any work location even at home. This technology
is also considered as flexible, also it consists of another advantage within it like storage and
payment through using it upgrade and add additional requirements which are needed in it. It also
has some key feature points in it like technology doesn't require backup plans in it, like there are
no risks related to data loss and data storage, through cloud technology it can be accessed easily
at the time in different devices. These technologies are simply used to share the data very easily
and safely (Growth Business, 2019).

LO2 Evaluate the deployment models, service models and technological
drivers of Cloud Computing and validate their use
P3 Define an appropriate deployment model for a given scenario
A cloud deployment model is simply a configuration of certain cloud parameters which include
data storage, size, and accessibility in it. There are 4 types of cloud deployment model are
present in cloud computing:
 Public
 Private
 Hybrid
 Community
Public cloud: This cloud model is mostly and widely use deployment model which is mostly
used model over these 4 models. Some of the most common example which is related to this
cloud model is IaaS, PaaS, SaaS. It is also used to manage and access the data files for the
organization. The basic advantage of public cloud is it is available at a low price, location
independent and it is very easy to solve the complexion and scalable ( Esds, 2019).
Figure 7: Public cloud
(Source: Esds, 2019)
Private cloud: It is used to address some of the main and important issues which are related to
the public cloud. In this deployment model, it is only using a single organization. It is also
known as internal cloud and cooperate cloud. It is also used to control privacy and security.
Private cloud deployment is used to control the data and flexible use of technology (Plusserver,
2019).
