Please find the attached question and my last week assignment.Make sure 0% Plagiarism and references should be in APA format. Need at least 2-3 pages.Using the four CSPs you used for the previous week’s assignment, conduct additional research on information they
provide to prospective customers on data security. Specifically look for protection while data is at rest (stored), while
data is being processed, and while data is in transit. If you find that the original concerns still exist, provide an opinion on
why there has been no change. If you find the concerns have been addressed, what contributed to the change? Also
research and discuss encryption used by the CSP. What type do they use?
Lastly, include steps for confirming their data protection practices.
Cloud Service Providers
The four leading public cloud providers in the world include Microsoft, Amazon Web
Services, Google, as well as Rackspace. There are various criteria that these service need to meet
and the comparison takes into account how well each of these cloud service providers meet the
set criteria. The criteria used in comparing the four CSPs are VM migration support,
Autoscaling, as well as network connectivity, among other features. AMS provides its users with
the most flawless VM migration path. It is the best VM migration path provider in the market
and is followed by Microsoft that is not far off behind. Through the use of a graphical device, the
various admin are in a position to manage the Amazon resources via a vCenter also making it
possible to migrate to the public cloud all the VMware VMs(Buyya et al., 2008). Microsoft
doesn’t provide a seamless process as is the case with AMS but it enables its users to migrate
VMs to and forth from the local data centers to the Azure. The process is easy although it has
some flaws. Google doesn’t allow its users to migrate VMs back or from the Google Compute
Engine Cloud even though it employs the services of third independent parties such as Cohesive
Networks that facilitate the migration of VMs. Rackspace doesn’t provide a means of migrating
VMs to or from its cloud.
Another critical aspect is auto scaling that is primarily the ability of the various cloud
providers to allow the available workloads to increase and decrease in regards to the current
demand. With Rackspace, there is aautoscale element that allow the cloud to increase as well as
decrease as in regards to the identified user-defined rules(Kim et al., 2009). Microsoft has
included a scale page that is intended to scale an application or introduce the parameters for
automatic scaling. Google also contains an autoscaler that is in a position to scale the uploaded
workload depending on the current demand; AWS has autoscaling abilities that are applicable on
a group basis.
Network connectivity is a fundamental feature that customers take into consideration
when settling for a cloud provider. The provider should provide the users with numerous
connectivity features to enhance connecting cloud network with the on-premises network. AWS
provides enhanced networking that guarantees the users high-performance networking that
enhance low jitter as well as latency. Rackspace provides the uses with numerous options for
networking to choose from. Google also provides its users with cloud DNS, primary cloud
networking potentials, as well as cloud load balancing (Buyya et al., 2008). Google also has an
interconnect feature with which the customers can directly link with Google or using a VPN.
Microsoft provides an Azure primarily designed to accommodate hybrid clouds. The Azure is
often utilized by users to act as an extension in regards to on-premises network.
With the current increase in CSPs, it is essential for the user to take certain factors into
consideration when settling for a particular CSP. These factors include the company’s cost limit,
the required features as well as designs. Other elements that need to be considered in this case
are the VM migration support, Autoscaling, custom image support, network connectivity, VM
migration storage choices, as well as regional support(Wei& Blake, 2010). These elements
determine the quality of services provided by the CSP as through these features and their
analysis, the consumer can determine the CSP that provides all its essential fundamental features.
