2. Describe each of the characteristics cloud services must have. Fshared services (with standard framework and shared application programming interface (API)) - these services can be shared in order for all users to have access to them Fstandard user interface - Web browsers to have access to the cloud services Fself-service - Users must help themselves by self service when it comes to doing cloud services since actions are carried over the computer, not from human to human Fservice metering - The Charge of the usage of the cloud services. Faccess over the Internet - The medium of having access to the Internet, as well as other places over the Internet

3. Explain horizontal and vertical services. Horizontal Services - cloud applications, cloud storage, cloud servers, and cloud collaboration. These horizontal services are the services that are spread around horizontally as the infrastructure, and the base of the cloud service. It provides the technology and memory for clouds for example. Vertical Services - government services, cloud entertainment, cloud publishing and online ad networks, cloud healthcare, and cloud telecommunications. These vertical services are basically what we use the cloud services for, which field they are in, and how they are used.

4. Define each layer of services. Infrastructure as a Service (IaaS) = this is a service usually from outsourcing done by an organization so that the actual infrastructure to hold the storage, hardware, and other components are stored elsewhere. Lass also defined as a computer infrastructure being as virtualization, being delivered as a service. In other words, Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.

Platform as a Service (PaaS)= Platform as a Service (PaaS) is a way to rent hardware, operating systems, storage and network capacity over the Internet. The service delivery model allows the customer to rent virtualized servers and associated services for running existing applications or developing and testing new ones. Application as a Service (AaaS)= Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

5. Explain the infrastructure capability terms Most of them are ITSPs and ISPs that have the resources and infrastructure capability, notably an Internet data centre, or iDC. True iDC and INET already provide cloud services for infrastructure and applications. In term of iDC, is when the companies had built a large facilities called Internet data centers, Which provide businesses with a range of solutions for systems deployment and operation.

6. Why is bandwidth important? Internet bandwidth will drive the popularity of cloud services in the country, as businesses and consumers will demand more services as bandwidth increases. Speedy network reliability is needed for "megabit-per-second" services. March 17 || 3.3_networks 3.4_internet 3.7_databases || According to the article, they mentioned that no corporation databases are not completely safe and secure enough to protect personal information. There are too much false which makes network perfectly safe. It is very large storage and contains a lot of personal information. If the network is too big, they can't manage the network well and all the weaknesses will occur. The hackers will aim to hack the corporate databases because it has a lot of information therefore; it is not actually very safe. 2. Should consumers be wary about providing personal data online? Yes, consumers should be wary about providing personal data online, because all services that store the online data are all under risk of being hacked, and the data compromised. Once the sensitive information is compromised, the user is more vulnerable to scam attacks through e-mails, as well as have their bank accounts or other user accounts online hacked. consumers should be a warning to be wary about providing personal data online because no corporate networks are frequently attacked by hackers and no matter how diligently their administrators work to protect them or how many protections are put n place, no network is perfectly secure. Even Sony' security systems are not perfect at all. Therefore, people have to be wary about providing personal data online 3. How valuable is data stored online? Data stored online is very valuable, especially sensitive information such as ID numbers and bank/credit card numbers. Other personal data such as names, passwords, and security question answers are useful for hackers, and can be easily used for impersonation on other sites to hack into user accounts for further bad intentions. || 1.2_security, 3.3_networks ||
