cloud computing meaning
cloud computing and cyber security 2020
cloud computing tutorial is the arm and arm delivery of the IT sources in the
internet . Instead of buying and physically maintaining the data servers you can access technology services such as computing and storing the data
services .
cloud
computing basics
we
need data servers from the data
suppliers such as AWS (Amazon web service ) .

Cloudsecurity has many contains
·
The third party handling the data
In cloud computing our data has been handled by the
third party . The third party is
accessing and managing the data . There is no guarantee given for the security
of the data .
·
Cyber attacks
We see many times that the data which is stored in the
cloud is getting hacked . This is one of the major issue we face regarding in the cloud computing .
·
Insider threats
In this the person who are working
on cloud can still our data so there is a high risk of the data privacy
·
Government intrusion
In this there is a surveillance type of the
system and there are many programs who
can monitor the data .
·
Legal liability
In this if you have kept your data in it and if that
is illegal then legal court case can be file against you .
·
Lack of support
Things comes under this category is
that the companies which are providing the support to the consumers .
·
Lack of the standardization
In this category the different cloud
suppliers are not always following the same kind of standards .
Cloud computing also
has some threat
·
Dos
Denial
of service attack is basically a attack in which the hackers are trying to
bring the servers down .
·
MIM
Man in
the middle attack is the attack means the conversation which is going between
the two parties is not secure .
·
NS
Network
sniping is the attack in which the network which is between the different cloud
servers is closely monitor
·
PS
Port
scanning = In this basically the hackers try to access the data which is present in the
cloud .
·
SIA
SQL injection attack is the
attack in which the hackers try to steal
the personal information such as
username , password etc .
·
Xss
Cross site scripting attack in
this attack if any user clicks on
the site he may reveals its identity to the hackers
Is cloud computing the future
Google
, Microsoft and many more companies
are making the big investments in the cloud
computing . In 2020 the estimated
revenue generated from the cloud computing is $ 266.4 Billion .
In
September the Microsoft pentagons picks
Microsoft for JEDI has surprised
everyone by making the contract in the cloud computing over the Amazon .
 |
| cloud computing and cyber security 2020 |
In
July the IBM closes the landmark for the acquisition of the Red hat for $34
Billion .
Cloud
computing is changing the way tie for the business in technology and managing
the data , shopping , video and text .
The
data is processed in the servers and
managing the data take the times .
When
the business is move to the cloud like Amazon
handles some companies like aws and it focus
on how they can do best .
They
can use the resources from the third party . so that your company can have
bigger data severs .
After
AWS the business like NETFLIX , slack
has also launched products in
their IT domains .
cloud
computing future
Amazon
has 26.8 %
alibaba
has 92.8 %
Google
has 60.2%
IBM
has 24.7%
Microsoft
has 60.9%
Revenue
growth infrastructure as a service cloud market
You
don’t need to make any big fundamental or investments .
With
the help of cloud computing you can access the data resources which is
available in the cloud .
cloud
computing architecture
The architecture has been divided into two parts
·
Front end
·
Back end
 |
| cloud computing and cyber security 2020 |
FRONT
END
The
front end is basically is a user interface for the client . you can access cloud through any browser .
BACK END
The
back end is basically a cloud provider .
In this all the resources are managed .
in this we can access the storing , virtual machine , security etc .
Now
we will look at the architecture in details
In
this the front end is basically a GUI which is called as graphical user
interface
|
Client side interface |
Client
side interface
|
internet |
|
Services Storage devices |
FRONT
END (GIU)
In
back end all the applications , services and storage devices are managed .
cloud
computing virtualization
cloud
computing virtualisation is that it allows to share single physical instance
of an application or resource among multiple organisations .
cloud
computing and virtualization
Hardware
virtualization
It
means that creating a virtual machine over the existing operating system and
hardware .
Virtual
machine is managed by a software known as hypervisor.
Host
machine
is the machine on which the virtual machine is created .
Guest
machine
is the virtual machine .
This
is how the virtualisation is done
cloud computing characteristics
1. Partitioning
In
the virtualisation many applications and software’s are supported in a single system
It
means in one machine we can create many
virtual machines . we can create different machines on a single physical system .
2. Isolation
Host
machine and the virtual machine should be isolated . Here the word isolated
means that it can work independently .
3. Encapsulation
In
this the virtual machine should be encapsulated in a single site .
cloud computing platforms
·
Amazon web service (AWS)
·
Google cloud platforms (GPC)
·
Microsoft Azure
In
this we can have same infrastructure as a service (Iaas) , load balancing , Networking and DNS , CND and
BLOB STORE , and governance .
We
can have the platforms as a service (Paas) , server less , container orchestration , database ,
and telemetry .
cloud
computing degree
To
make a career in cloud computing one
should have completed his 12th
class college and then he can move further for certifications .
One
can go for the certification of Microsoft , Google and Cisco .
