Cloud computing is connecting with the entire world

3. It is a phrase used to describe a variety
of computing concepts that involve a large number of
computers connected through a real-time
communication network such as the Internet.
In science, cloud computing is a synonym
for distributed computing over a network, and means
the ability to run a program or application on many
connected computers at the same time.
In common usage, the term "the cloud" is essentially a
metaphor for the Internet.

5. IT PROVIDES BASICALLY THREE TYPES OF SERVICES :
1. SAAS
2. PAAS
3. IAAS

7. INFRASTRUCTURE AS A
SERVICE
In the most basic cloud-service model, providers
of IaaS offer computers – physical or (more often)
virtual machines – and other resources.
IaaS clouds often offer additional resources such
as a virtual-machine disk image library, raw
(block) and file-based storage, firewalls, load
balancers, IP addresses, virtual local area
networks(VLANs), and software bundles

8. PLATFORM AS A SERVICE
In the PaaS models, cloud providers deliver
a computing platform, typically including
operating system, programming language
execution environment, database, and web
server. Application developers can develop and
run their software solutions on a cloud platform
without the cost and complexity of buying and
managing the underlying hardware and software
layers.

11. • COST EFFICIENT
• ALMOST UNLIMITED STORAGE
• BACKUP AND RECOVERY
• AUTOMATIC SOFTWARE INTEGRATION
• EASY ACCESS TO INFORMATION
• GLOBALIZE OUR WORK
• STREAMLINE PROCESS
• IMPROVE FLEXIBILITY

12. SECURITY AND CONFIDENTIALITY
Since technology has started to expand in the
exponential ways we are seeing in this day and
age, cyber-crime has become a concerning
issue. Cloud computing does pose the risk of
increased security threats. While most
companies have an up-to-date virus database,
this does not make the files and information
stored in the cloud immune to hackers.

13. LESS CONTROL
By using this technology you risk losing a level
of control over your company. While many IT
managers are experimenting with various ways
of implementing an in-house cloud system that
runs on delivered metered services, this is not
always the most lucrative business move.
TECHNICAL ISSUES
this technology is always prone to outages and
other technical issues. Even the best cloud
service providers run into this kind of trouble, in
spite of keeping up high standards of
maintenance. Besides, you will need a very good
Internet connection to be logged onto the server
at all times. You will invariably be stuck in case of
network and connectivity problems.

14. • Like any new technology
advancement, cloud computing
also creates disruptive
possibilities and potential risks.
• The fact that cloud computing
involves the aggregation of
computing power, and more
importantly, information, has
become a source of increasing
concern.

15. The top favorite among CSPs was,
quite unsurprisingly, Amazon.
Amazon offers a vast spectrum of
cloud services with its
infrastructure, called Amazon Web
Services. This includes offering
such as EC2 compute, S3 storage
and so on.
Google is yet another cloud
provider which has found its way
right to the top of the heap.
Offering several features and
functionality, the search giant’s
Compute Engine (GCE) forms the
very essence of its cloud services.
What GCE lacks in a management
console, it makes up in speed.

16. Yet another top contender, again
unsurprisingly, is Microsoft, which
is now emerging as a formidable
CSP. The company is unique, since
it uses the selfsame infrastructure
software for running apps on-premise
or in the cloud. Microsoft
additional provides Windows
Azure, its own PaaS offering.
SPIDEROAK
One of the
most secure
cloud
providers,
SpiderOak
enables users
to protect
their data
with
encryption,
so as to
prevent
unauthorized
access of the
same.
SUGARSYNC
As the name suggests, SugarSync basically
provides file sync and file sharing services.
This provider offers 5GB of free storage space.
You can switch to a paid package if you need
more space.
