Initial Post 1: Facebook as a SaaS Facebook can best be described as Software as a Service. From the description of the SaaS, the user does not need software installed on the computer to access it. This is the same case for Facebook. It can be accessed through the browser. All that is required is to create an account. From anywhere, it will be easy to access it. What is in question regards payment. Facebook needs payment to be done when making advertisements. This is paramount and a requirement. Facebook fails to qualify as PaaS, on the other hand. On PaaS, an environment is provided (Erl, Puttini & Mahmood, 2013). This means that the user is supposed to create their own customized application. However, they will still be under the provider. Other attributes that fit Facebook as SaaS are the limited control granted to the users. The control and configuration of the appearance are managed by the provider. As such, the user is left to conform to the requirements provided on Facebook rather than improve the environment. Software as a Service (SaaS) Software as a Service is a product (Erl, Puttini & Mahmood, 2013). It is not installed to the user computer or in the organization’s system but is accessed through the internet from the respective computers (Erl, Puttini & Mahmood, 2013). Lack of an environment justifies that the SaaS, unlike PaaS can be used for diverse activities in the organization. It is not limited to a basic configuration which can be done with ease as per the needs of the user. A browser is the only required software in this case. SaaS can be accessed anywhere through the browser (Benlian & Hess, 2011). For instance, Google Docs is an example of SaaS. To access SaaS, one needs to ensure that they log into their Google account and access the doc, spreadsheet, PowerPoint, and excel. As such, I believe that SaaS best fits social media. As well, it can best be used for activities that do not need a lot of activities or are not used often. A well, like social media such as Facebook and LinkedIn, it can be used when the application needs to be accessed by both computers and phone. Using SaaS, accessibility is made simpler. Deployment Model Public cloud is the most appropriate deployment model for both Facebook and LinkedIn. An insight into the characteristics of the public cloud clearly matches with Facebook and LinkedIn. Although classified as relatively not strong, the public cloud is usually secure (Dillon, Wu & Chang, 2010). There is easy accessibility of the services and the systems by the users (Erl, Puttini & Mahmood, 2013). Facebook and LinkedIn are open for public use which is one of the attributes of public cloud. In relation to the private cloud, Facebook and LinkedIn do not qualify due to the limited accessibility. The high scalability of both Facebook and LinkedIn makes more public. On the other hand, a private cloud is more limited and is actually applied to organizations (Erl, Puttini & Mahmood, 2013). There are tight security and limited access to users. This is an attribute that is not evident to Facebook and LinkedIn. As such, without a doubt, Facebook and qualify to be a public cloud when it comes to deployment models. Initial Post 2: Out of my insight, I think Facebook uses Software as a Service (SaaS) cloud computing solution. A PaaS affords hardware and software equipment over the internet, and those use this equipment to develop applications. PaaS users are mostly developers. SaaS platforms make software program available to users over the internet. This is precisely applicable to "Facebook" users. Following the definition of cloud computing, "Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction” (Grance, 2011), and With SaaS, users don’t need to put in and run software programs to their pc. Everything is available over the internet while you log in on your account online. Users can usually get admission to the Software from any device, anytime so long as there may be a web connection (Thomas, 2008). Taking all the above points into consideration, in the end, Facebook can be considered as a SaaS cloud computing solution. On the flip side, there are also arguments that Facebook is nether SaaS nor PaaS. SaaS Characteristics: 1. Available over the net. 2. Hosted on a remote server via a third-party provider. 3. Scalable, with different sizes for small, medium, and enterprise-level businesses. 4. Comprehensive, offering protection, compliance, and maintenance as part of the cost. SaaS platforms are perfect for users when a user wants the software to run efficiently and reliably with minimal input from them. For instance, consider E-mail server. We use e-mail just for communication purpose and sharing files, documents etc. in this scenario, Users no need to worry about updates and settings. Moreover, there will be cases when the server cracks down, and users cannot access their mails. In such situations, a SaaS platform is used to run e-mail. Using SaaS solutions minimizes such risks (Kim, 2009). I believe the hybrid cloud is the most appropriate deployment model for a social media site such as Facebook or LinkedIn. Hybrid cloud is a combination of the cloud computing deployment models like public, private, and community cloud deployment model. One of the most common uses of a hybrid cloud is a mixture of public and private clouds with touchy data staying in a private cloud, and different less vital data stored in a public cloud. There are many advantages in adopting hybrid cloud-like hybrid clouds enable in maintaining sensitive data safe (O. Sharma, 2015). Get some of the scalability and cost-effectiveness of public cloud, Ultimate flexibility. Flexibility is the primary drawcard of the hybrid cloud. By combining specific deployment models, users may select and choose the perfect stability between legal compliance, protection, and scalability. If nether public cloud or private cloud meet all the objectives and needs of the user, Hybrid cloud might work out in such cases, and for these reasons, I believe hybrid cloud is the most appropriate deployment model for a social media site.
