Software as a Service (SaaS) allows users to connect to and use cloud-based apps over the internet. Common examples are email, calendar and office tools (such as Microsoft Office 365). It is a licensing and delivery model for software hosted in the cloud by a service provider and made available to users over the internet on some form of incremental pay-as-you-use fee. Accessing software in this way has become part of the strategy of nearly all large enterprises and many smaller ones. The providers of SaaS services include Office 365, Adobe and Google Apps. 16. When a business rents the capabilities of a PC via the cloud, is the cloud service provider typically allocating a physical PC which will be dedicated to that customer? Why or why not? (2 marks) Because the provider's business model is based on managing the space and applications that the customer requires instead of renting a physical space as such. In other words, the provider should be able to service several clients with the same infrastructure or shared hardware. 17.

Provide TWO (2) examples of the SECaaS providers. (3 marks) Security as a service (SECaaS or SaaS) is a business model in which a service provider integrates their security services into a corporate infrastructure on a subscription basis more cost effectively than most individuals or corporations can provide on their own, when total cost of ownership is considered. The providers of SECaaS include Oracle Cloud Access Security Broker (CASB) and OKTA. 19. Why is it necessary to seek assistance from specialist advisors to determine relevant cloud computing services? (4 marks) While ICT decisions are risky and expensive, most non-technical people in business do not have the background or time to fully understand new concepts and technologies. However, the technical people who can heavily influence the final decisions do not always understand all the issues either. In these situations, it is beneficial to seek expert advice. Although it may be costly to use consultants, the up-side is the assistance they bring, not only for planning but in the implementation phases that follow. 20. When consulting with outside advisors and using services of specialist advisors, it is important to follow business protocols. What does the term “business protocols” mean? (2 marks) Business protocol is a general term that may define several aspects of a business. Everything from behaviou r and dress to task execution is defined under a business’s protocol. These guidelines are typically defined for each employee upon being hired. Employees might be asked to provide written proof that they have read, understood and agree to the terms of the ir company’s protocol. Assessment 1 total: 80 marks

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
