According to Bruce Schneier,
"The downside is that you will have limited customization options. Cloud computing
is cheaper because of economics of scale,
and—like any outsourced task—you tend to get what you want. A restaurant with a
limited menu is cheaper than a personal chef who can cook anything you want.
Fewer options at a much cheaper price: it's a feature, not a bug." He also
suggests that "the cloud provider might not meet your legal needs"
and that businesses need to weigh the benefits of cloud computing against the risks.[129] In
cloud computing, the control of the back end infrastructure is limited to the
cloud vendor only. Cloud providers often decide on the management policies,
which moderates what the cloud users are able to do with their deployment.[130] Cloud
users are also limited to the control and management of their applications,
data and services.[131] This
includes data caps,
which are placed on cloud users by the cloud vendor allocating a certain amount
of bandwidth for each customer and are often shared among other cloud users.[

Cloud computing has some limitations for smaller business
operations, particularly regarding security and downtime. Technical outages are
inevitable and occur sometimes when cloud service providers (CSPs) become
overwhelmed in the process of serving their clients. This may result in
temporary business suspension. Since this technology's systems rely on the
Internet, an individual cannot access their applications, server, or data from
the cloud during an outage.

Advantages of Cloud Computing
Cloud-based software offers companies from all sectors a number
of benefits, including the ability to use software from any device either
via a native app or a browser. As a result, users can carry their files and
settings over to other devices in a completely seamless manner.
Cloud computing is far more than just accessing files
on multiple devices. Thanks to cloud computing services, users can check
their email on any computer and even store files using services such as Dropbox
and Google Drive.56 Cloud computing services also make it possible for
users to back
up their music, files, and photos, ensuring those files are
immediately available in the event of a hard drive crash.
It also offers big businesses huge cost-saving potential.
Before the cloud became a viable alternative, companies were required to
purchase, construct, and maintain costly information
management technology and infrastructure. Companies can swap costly
server centers and IT departments for fast Internet connections, where
employees interact with the cloud online to complete their tasks.
The cloud structure allows individuals to save storage space
on their desktops or laptops. It also lets users upgrade software
more quickly because software companies can offer their products via the web
rather than through more traditional, tangible methods involving discs or flash
drives. For example, Adobe customers can access applications in its Creative
Cloud through an Internet-based subscription.7 This allows users to
download new versions and fixes to their programs easily.

Disadvantages of the Cloud
With all of the speed, efficiencies, and innovations that
come with cloud computing, there are, naturally, risks.
Security has always been a big concern with the cloud
especially when it comes to sensitive medical records and financial
information. While regulations force cloud computing services to shore up their
security and compliance measures, it remains an ongoing issue. Encryption
protects vital information, but if that encryption key is lost, the data disappears.
Servers maintained by cloud computing companies may fall
victim to natural disasters, internal bugs, and power outages, too. The
geographical reach of cloud computing cuts both ways: A blackout in California
could paralyze users in New York, and a firm in Texas could lose its data if
something causes its Maine-based provider to crash.
As with any technology, there is a learning curve for both
employees and managers. But with many individuals accessing and manipulating
information through a single portal, inadvertent mistakes can transfer across
an entire system.

Advantages of Cloud
·
Low Cost: To run cloud technology, users
don't require high power computers and technology because the application will
run on the cloud and not on users' PC.
·
Storage capacity: The Cloud storage
capacity is unlimited & generally offers a vast storage capacity of
2000-3000 GBs or more based on the requirement.
·
Low cost of IT infrastructure: As discussed
earlier, the investment will be less if an organization uses Cloud technology;
even the IT staffs and server engineers are also not required.
·
Increase computing power: Cloud servers
have a very high-capacity for running and processing tasks and the processing
of applications.
·
Reduce Software Costs: Cloud minimizes the
software costs as users don't need to purchase software for organizations or
every computer.
· Updating: Instant software update is possible & users don't have to face the choice problem between obsolete & high-upgrade software.
From <https://w3schools.in/cloud-computing/>
Disadvantages of cloud
·
Internet speed: Cloud technology requires a
high-speed internet connection as web-based applications often require a large
bandwidth amount.
·
Constant Internet Connection: It's impossible
to use cloud infrastructure without the Internet. To access any application or
cloud storage, a constant internet connection is required.
· Security: Data storage might not be secure. With cloud computing, all the data gets stored in the cloud & hence the unauthorized user may gain access to the user's data in the cloud.

Limitations Of Cloud Computing
Although there are myriad benefits of Cloud Computing, it
has certain limitations, as discussed below:
Variable performance:
When working in a Cloud environment, your application runs
on a server that simultaneously offers resources to several other businesses.
Any DDOS attack or covetous behaviour on your Cloud computing platform can
influence the overall performance of your shared resource.
Prone to technical issues:
There are high risks of outages and other technical issues
with Cloud technology. Even the renowned cloud service providers might perceive
this trouble notwithstanding preserving the high maintenance standards.
Downtime:
Your Cloud provider might suffer from poor Internet
connectivity, power loss, service maintenance, etc.
Odds of security threat in the Cloud:
Before implementing Cloud technology, keep in mind that you
would be sharing your organisation’s sensitive info with a third-party type
cloud computing service provider. This information may be susceptible to
hackers.
Depends on Internet connectivity:
Decent Internet connectivity is mandatory in cloud
computing. It is impossible to access Cloud in the absence of an internet
connection. No other way is available to assimilate data from Cloud.
Lower Bandwidth:
Several cloud storage service providers restrict the
bandwidth consumption of their users. If an organisation exceeds the specified
allowance, extra charges can be significantly expensive.
Limited flexibility and control:
The Cloud infrastructure is wholly owned, administered, and
supervised by the respective service provider. So, it assigns minimal control
over the customer. A Cloud provider's management policies and end-user
licence agreement (EULA) may levy limits on what customers can accomplish with
their deployments.
Risk of data privacy:
Customers often fear for their data safety. With cloud,
there remains an issue regarding data confidentiality or breach. Thus cloud
providers must ensure confidentiality and security.
Inadequate Support:
Cloud Computing companies are unable to offer adequate
customer support. Furthermore, they anticipate their user to rely on online
help or FAQs. This can be a challenging task for non-technical
individuals.
