Discussion and student response

Many organizations are moving to the cloud to protect their  infrastructure, reduce infrastructure costs, and improve their backup  capabilities. As a cybersecurity practitioner, you may very well be  asked to assist in the selection and implementation of a cloud computing  service model.

Go to Basic Search: Strayer University Online Library to  locate and integrate at least two quality, academic resources (in  addition to your textbook) on the cloud computing service models defined  by the National Institute of Standards and Technology (NIST). You may also use government websites, such as Cybersecurity from the National Institute of Standards and Technology.

Please respond to the following in a post of at least 200 words:

  • Compare and contrast the cloud computing service models defined by NIST.
  • Integrate practical examples of organizations you have researched  that that are using the various platforms, highlighting the advantages  and disadvantages of each.
  • Provide full citations and references, formatted according to Strayer Writing Standards.
    • For assistance and information, please refer to the Strayer Writing  Standards link in the left-hand menu of your course. Check with your  professor for any additional instructions.

In 60 to 75 words, please respond to at least one other post. Choose to respond to those who have few or no responses. 

Note: You will find the information from this post  and the feedback you receive on it useful as you prepare your final  Cloud Computing assignment due this week.

Hi Professor and Class!

 

Looking at the cloud computing service models provided by the National Institute of Standards and Technology (NIST), We have Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) (NIST, 1). All three are important and answer problems that companies have. Starting with Software as a Service, “The capability provided to the CSC is to use the CSP’s applications running on a cloud infrastructure. 6 The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The CSC does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings”. OnlyDomains is a company that uses SaaS, and they provide software that allows customers to obtain domain names, email addresses, web hosting, and a website building tool. (AccelerateAgency, 2).

 

The second is Platform as a Service, “The capability provided to the CSC is to deploy onto the cloud infrastructure CSC-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider.*3 The CSC does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.” An example of this is Heroku.com, they provide customers with a platform to create an app using their provided tools.

 

Last, Infrastructure as a Service, “The capability provided to the CSC to provision processing, storage, networks, and other fundamental computing resources where the CSC can deploy and run arbitrary software, which can include operating systems and applications. The CSC does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications, and possibly limited control of select networking components (e.g., host firewalls).” An example of this is AWS. This type of service allows companies to host their servers, networks, OS’s, etc. in the cloud.

 

Thanks!

 

Justin
