Cloud computing is one of the highly dependable technology
solutions claimed by the service provider. However, recent hacking attacks
clouds of Apple Inc. and Sony pushed back many companies from adopting cloud
technology. However, the recent disclaimer of former U.S. Secretary of Defense
Donald Rumsfeld lots of negativity is circulated in the business market. To
clarify things on cloud computing Dubai so that companies stop believing on
risks often linked to cloud technology.
Risk No. 1: clouds work on shared access:
One of the prominent features of public cloud is multi-tenancy
which means that multiple users share the same computing resources, such as,
memory, the physical building, memory storage and CPU. Multi-tenancy is now very
common concept, where the risk of confidential information sharing always
presents. Not only can this, but exploitation and accidental information
sharing happen at any point. Because one flaw can automatically make the whole
cloud where other clients can also suffer from data breaches.
There are several issues that may rise because of
multitenancy, although, researchers have been able to recover other tenant’s
data and move it to another “New Storage” space. New security measures are
discovered to protect data stored on public clouds that have reduced the risk
factor significantly.
However, with time issues and risks associated with the shared
approach are explored and given significant importance that has helped
companies overcome data breach issues with multitenancy. The best example of
this kind is a web server, where one website is placed with thousands other,
unrelated websites.
Risk No. 2: Virtual exploitation:
Another significant risk associated with cloud computing Dubai is its virtual exploitation. Generally, every large cloud service
provider is an important user of virtualization. However, it associates it with many other
risks caused by physical machines, its own created threats, including external
exploits that target virtual server hosts and its guests. There are four types
of virtual exploits than can happen on clouds, such as guest to guest, guest to
host, server host only and host to guest.
However, these exploits can happen because most managements
never see any vulnerability in their system and they bypass this can happen to
their virtual server. But if they consider virtual exploits seriously and check
their own virtualization software vendor patch list and other virtual
management tools than they can easily reduce risks.
Risk No 3: Availability
For customers of public cloud computing Dubai, it is impossible
to deal with redundancy and faultiness. Usually, back-end details are not
shared with the customers. It is completely opaque for the customer. Customers
are provided with the technical coverage service as well, however, they find
them hopeless when service interruptions happen again and again.
The customer becomes more concerned when they lost access to
their data and sometimes never get the recovery. In most situations, cloud
service provider gives a guarantee of 100% backup after the crash, but lots of
data can never recover. To avoid such situations, often companies are
recommended to keep an in-house backup, and in some cases cloud service
providers provide this backup. This way they can reduce the risk of data loss.
