You are to provide simple, plain language explanations for each of the following terms:
1. Mission Critical Systems
Mission-critical system are those that can stop an organization from performing its core functions if they fail.
2. Desktop and Office productivity
Another important factor in business computing is desktop office productivity software and systems. This refers to the application software used by staff in the organization at their desks, and progressively via mobile devices, as a general tool contributing to their productivity.
3. Cloud computing
Cloud computing involves accessing computing resources from remote location rather than from those located at the site of business activity.
Virtualisation is the process of making software-based, or virtual, representations of things, such as servers, applications and networks. It’s an effective way for a business to reduce IT expenses and boost efficiency and agility.
In computing, virtualization refers to the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources
5. Cloud ownership – 3 types
Private Cloud: the cloud services used by a single organization, which are not exposed to the public. A private cloud resides inside the organization and must be behind a firewall, so only the organization has access to it and can manage it.
Public Cloud: the cloud services are exposed to the public and can be used by anyone. Virtualization is typically used to build the cloud services that are offered to the public. An example of a public cloud is Amazon Web Services (AWS).
Hybrid Cloud: the cloud services can be distributed among public and private clouds, where sensitive applications are kept inside the organization’s network (by using a private cloud), whereas other services can be hosted outside the organization’s network (by using a public cloud). Users can them interchangeably use private as well as public cloud services in every day operations.
6. Software as a Service (SaaS)
Software as a Service (SaaS) is a licensing and delivery model for software hosted in the cloud by service provider and made available to user over the internet on some form of incremental pay-as-you fee. It is sometimes referred to as on-demand software. Some types available are: Office productivity tools and systems; Email and other messaging; Customer relationship management (CRM) tools; Warehouse and inventory management; etc.
7. Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is a form of cloud computing that provides access to computing hardware (virtualised or not) over the internet. It separates the user from being concerned about details of the infrastructure they are using. Might be described as a remote machine without software. Some providers include: Amazon AWS, Windows Azure, Google Compute Engine, etc.
8. Platform as a Service (PaaS)
Platform as a Service (PaaS) is a category of cloud computing providing clients with a mix of hardware and software to enable development, testing and deployment of user applications. The attraction of the PaaS approach is that its clients don’t need to own, set-up and maintain the required hardware and software components themselves. Instead, they can have they can have them provided quickly, almost on demand, and pay on a scaled rental.
9. ‘Thin’ client
A ‘Thin’ client provides desktop users with application functionality comparable to traditional software applications suites without needing a big, powerful PC huge memory and hard drives. ‘Thin’ client often means a browser, a good example is Google Chromebook.
10. Total cost of ownership (TCO)
The TCO extends beyond the initial price to include all financing, installation maintenance cost as well as associated staff cost.
11. Describe two (2) possible benefits of integrating cloud computing solutions for the business.
1. Have the software in the phone or tablets so the employees can book jobs and send invoices for example, been able to access for a anywhere, so they can be more efficient.
2. All business systems talk which other, for example Customer relationship management (CRM) and accounting software.
12. Describe two (2) possible risks of integrating cloud computing solutions to the business.
Training costs, some workforce will sabotage the change, or take longer to accept the change.
Losing information or don’t be able to log on the system, because of a breakout or no internet connection
13. Describe two (2) possible security and privacy concerns of integrating cloud computing solutions for the business.
1. Connectivity issues, without a continuous data connection to the cloud, cloud services stop. Mobile works my have problem using cloud services, because still have geographic dead zones in internet coverage.
2. Any company can fail and cease to trade, and it can happen overnight, this is just true for companies offering cloud services. It would be potentially disastrous for a business to find it had all its business data, customer records and critical operational systems provide via a company that is simply not there tomorrow. This is one of the major considerations against cloud computing. If things are in-house then, at least in theory, they are safe and under control.
14. Identify two (2) different sources of technical support and/or specialist advice, to assist with cloud computing solutions for a business.
Advice directly from the cloud service specialist. Usually if the business pays a fee it may have already a technical support available, some cloud services may charge a higher fee or a special fee just for the business have a technical support. Other option for the business it to pay a reputable ICT cloud consultant. My email is: firstname.lastname@example.org
