Cloud computing offers businesses significant advantages like cost savings, easy data sharing, automatic backups, and reduced costs. However, security and reliability are two major disadvantages - outages at large cloud providers like Amazon can impact many companies. While cloud computing improves efficiency, businesses lose some control over software and depend on providers, so outages can cause issues. Security is also a concern if sensitive data is compromised through a provider's systems. For businesses to benefit from cloud computing, providers must ensure reliable, scalable infrastructure and capacity to meet growing demand.

2. INTRODUCTION
Cloud computing is a model of computing in which computer
processing, storage, software, and other services are provided
as a pool of virtualized resources over a network, primarily the
Internet. These clouds of computing resources can be
accessed on an as-needed basis from any connected device
and location. The term "Cloud Computing" has appeared on
the radar screen of information systems/information technology
and business professionals over the last few years. The term
"Cloud" refers to the Internet and "Computing" refers to the use
of technology.

4. Cloud computing has become a standard method of
software operation for many businesses. It offers many
significant advantages, such as a potential cost savings,
ease of sharing data and applications, quickly find the
desired information, automatic backups, reduced support
and maintenance costs and improve the efficiencies.

6. Using the cloud computing, the two major disadvantages are
security and reliability. In this case study, Amazon's cloud
service has shown significant outages in 2011 and 2012,
causing serious consequences. There are many large sites are
using Amazon's cloud computing, so Amazon's cloud computing
failure will not only affect Amazon, but also spread to many
other companies and have a great impact on them. It also
because the user loses control over the software application
and becomes dependent on the provider to maintain, update
and manage it. If something goes wrong, the user does not
have direct access to the software and must depend on the
provider to fix the problem. If the provider is unresponsive or
unable to fix the problem quickly, the user can experience
significant issues. According to the Paris International Group of
a report, after investigation they found that each year there are
about ten hours or more the server fails.

7. Another important issue is security. By using a cloud system,
your company’s sensitive data and information will be stored on
third-party servers, and you will probably have very limited
knowledge or control regarding this information. If the provider
has inadequate security or encryption systems or procedures,
or if a breach of these systems or procedures occurs for any
reason, your company’s private and confidential data may
become compromised. This could have devastating effects, and
could cause legal problems for your company if third party
confidential information (for example, customer information) is
compromised.

8. Total Cost Ownership (TCO) is a financial estimate intended to
help buyer and owners determine the direct and indirect cost
of a product or system.
Amazon must provide hardware capacity planning and
scalability. With the development of information technology,
Amazon will have more and more customers. Not just Amazon,
but Amazon's customer requires a large database to store a
variety of data and information. This will help the company
grow. Amazon must bear the total TCO of its services, while
Amazon is also needed to maintain the profitability of the
company. However, the services' subscribers benefit from not
having to worry about these issues.

10. Capacity planning is defined as the process of predicting when
a computer hardware system becomes saturated to ensure
that adequate computing resources are available for work of
different priorities and that the firm has enough computing
power for its current and future needs. Indeed, Amazon must
plan its future needs to be capable of providing sufficient
computing power for both AWS and Amazon retail services, a
lack of which will result in the a fore mentioned rejection by
subscribers.

11. Related to capacity planning is scalability, which is defined as
the ability of a computer, product, or system to expand to
serve a large number of users without breaking down.
Scalability is a ability of a system, network or process to
handle a growing amount of work in capable manner or its
ability to be enlarged to accommodate that growth. Scalability
relates to both Amazon and AWS subscribers. Amazon must
be able to provide its customers with services that are
scalable, as it claims to do on its website: “Take advantage of
our massive compute capacity and storage to build whatever
kinds of applications your business demands, no matter how
fast it grows or how big it gets”.

13. As information technology and social development, there have been more
and more companies need cloud services. First, the information Internet
companies need to use cloud services, such as Facebook, Google,
Instagram, Blogspot, Ebay, etc. Because the cloud computing can store
large information, and share the information. Second, large multinational
corporations, one of the advantages about the cloud computing is that
people from around the world can get a faster connection
Cloud services can help employees of multinational corporations to establish
good communication channels and share the company's resources. This
saves the cost of the work to help multinational companies, improve work
efficiency. Meanwhile, cloud computing is not perfect, it is sometimes also
appear outage. Therefore, it is recommended to use cloud computing
company “would be a major risk consider using another computing service
as a backup.” Enterprise-class business cloud services can be hugely
beneficial, even for quite small businesses.

Regardless of whether a cloud provider sells services at a low level of
abstraction like EC2 or a higher level like AppEngine, we believe computing,
storage, and networking must all focus on horizontal scalability of virtualized
resources rather than on single node performance.
