ISP is internet service provider. Peering is a process by which two internet networks connect and exchange traffic. It is used because it is cheaper and sometimes easier to control traffic flows.

Under what conditions can the Internet strengthen supplier bargaining power? Be able to give an example.

If network effects are strong or a seller's goods are highly differentiated, the internet can strengthen supplier bargaining power. Example: In the airline industry, fuel is a major component and their are only two main suppliers of it: Boeing and Airbus.

Suppose now your company wants to adopt an enterprise software application (e.g., CRM, ERP) and you have two options - buying some packaged enterprise software or using software-as-a-service model (i.e. getting on-demand enterprise software). What are the benefits of buying the packaged one and what are the benefits of getting the on-demand one? Understand how the size of your organization affects your choice.

If the size of the organization is large, SaaS model is the better option since it helps reduce costs, provides the advantage of being highly scalable, and generally have higher quality and service levels. If the organization is small, the packaged enterprise software option is beneficial because they are easier to work with, especially for firms that don't have IT professionals, the software is the same throughout the company, and it makes purchasing decisions easier.

What is IaaS? For this service model, what are the resources the cloud vendor will provide/manage and what are the resources the cloud user will have a control? What basic question is it essentially addressing for a cloud user?

Infrastructure as a service offers an organization an alternative to buying its own physical hardware. The cloud vendor usually manages the infrastructure whereas the cloud user can select their own operating system, development environments, underlying applications, and other software packages.

Net neutrality is the concept that ISPs treat all internet communications equally and do not discriminate or charge based on user, content, website, content, etc. Netflix and Facebook are companies that support net neutrality. Verizon, AT&T, and Comcast are against net neutrality. This is because ISPs are the ones who benefit most because they can charge higher amounts for those who use more or slow down services. For companies like Netflix, they want their streaming to be consistent so they can maintain their users base. I would side with companies like Netflix and Facebook to ensure that all users are experience a fair experience when using the internet.

What is net neutrality? Who would you side with, Netflix or the large ISPs? Why?

Net neutrality is the principle that all internet traffic should be treated equally and that ISPs should not discriminate, slow down access, or charge differently per use, content, site, platform, application, type of attached equipment, or modes of communication. I would side with Netflix because when internet traffic is not treated equally, it puts a strain on the consumers who don't know what speed or prices to expect from the products and services via internet they are using.

What "class" of software does Netflix use to make movie recommendations? Think about Chapter 2: Which key competitive resource does this software "create"? What kinds of benefits does this provide to the firm? How does the long tail effect interact with its recommendation software?

Netflix uses collaborative filtering called Cinematch. It gives a competitive resource by harnessing powerful, detailed data. It benefits the firm by improving customer experience, building brand, and creating a switching cost. The cinematch suggests obscure movie as it knows the customer better, improving customer experience and better relations with the supplier.

What is PaaS? For this service model, what are the resources the cloud vendor will provide/manage and what are the resources the cloud user will have a control? What basic question is it essentially addressing for a cloud user?

Platform as a service delivers tools so an organization can develop, test, and deploy software in the cloud. The vendor provides the platform such as hardware, operating system, database, and other software. The user controls the applications they build using the vendor resources. The basic question it addresses for a cloud user is where can I develop/store my applications.
