Amazon Web Services (AWS) - Amazon's web service that provides companies with infrastructure web service platforms in the cloud. Amazon's Elastic Computer Cloud (EC2) - A web service that provides resizable compute capacity in the cloud, designed to make web-scale computer easier for company developers. Amazon's Elastic Block Store (EBS) service - this service provides block level storage volumes for use with Amazon's EC2 instances. The EBS volumes are off-instance storage that is independent from the life of an instance. http://aws.amazon.com/ 5. If possible, describe a solution to the concern (issue). A solution to the reliability concern is for businesses and companies to filter out what they plan to put on Amazon's cloud services, and what to keep in their private network within their control. Balancing the two would beneficial and can prevent a lot of damage that a failure of a server may do the company as well as its files and data stored in the cloud. Amazon explaining how their cloud service actually works and have it backs up everything should be able to calm down businesses, and regain their trust again once everything is back up and running again.

Why might some people want to use tablets? They are lighter and easier to carry around than PCs and easier to control because it is touch screen so you don't need a mouse to control the cursor, and just touch the screen. It may not be good for typing up documents, but they are easy for online searches as you don't need to sit down, open the laptop and search, but just do it on the spot.

Which would you use? march 17 kuni

I would use Google Sketchup, because this is one of the applications that I have on my computer. Google Sketchup is a software with which you can make a 3D model easily. Compared to the other 3D modeling software, Google Sketchup is easier to use. It has some tutorials for beginners, and you will find out how easy it is to create 3D model like a kid making a tower of blocks. Also, if you buy it, you will be able to convert it to a file that can be used for other 3D modeling software and modding games. I would use Google Trends just to see what's trending and Flight simulator in Google earth sounds pretty fun for when you're bored. I would use ; Google Page Creator, Flight simulator in Google Earth, and SketchUp. I would use the fight simulator, because it looks fun, and SketchUp mainly because I've always wanted to do some sort of graphics design on the computer. -In my opinion I would like to use Google SketchUp, and Google Book Search. First of all Google Sketch Up is helping me to make 3-D model. This is very useful in art class because when we have something like installations, we need some sketch of location and installation therefore by this program, I can draw 3-D installation and see how it looks like therefore this program is very useful for me. Also For the Google Book Search, this is kind of digital library which I can find book very easily and efficiently. I can see the books by this program also I can upload by own books which I can scan it. Therefore it might be very useful when I have something like writing essays. I would use Google Page creator. It enables to me create a page where I can find snippets of web pages, quotes, and images all over the web.

Identify the area of impact the scenario relates to. Business Identify the main stakeholders to the IT system. Sony, Geohot, users of PS3, users of Geohot, twitter, youtube, Google 3. Identify one ITGS social/ethical concern in the article. Privacy and anonymity 4. Describe ITGS terminology and systems. IP address : An Internet Protocol address (IP address) is usually a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Sources : http://en.wikipedia.org/wiki/IP_address iOS : iOS is Apple's mobile operating system. It was originally developed for the iPhone, and it has extended to support other Apple devices such as the iPod touch, iPad and Apple TV. Geohot : George Hotz, known for working with other people to unlock the iPhone, allowing the phone to be used with other wireless carriers. 5. If possible, describe a solution to the concern (issue). There is no possible solution because even if Sony gets hold of all IP addresses, there will be alternate ways for users to still access GeoHot's websites and videos. Moreover, the US justice system shouldn't give rights to companies to access personal information, because it is basically invading peoples' privacy.

Why does apple rank low for being green? Which companies are fairly green? Why don't companies want to disclose their energy consumption? Is cloud computing green? Determine if use of IT often reduces environmental impacts or not. april 28 nat

Why does apple rank low for being green? Because of their huge electricity consumption and the increase in their consumption in a new facility, which consumes approximately the same amount of electricity 80,000 US homes. Which companies are fairly green? Yahoo, Google and Amazon. Why don't companies want to disclose their energy consumption? They don't want others to know what they did or what they had to do to reach to the position they are in now. Is cloud computing green? No, it's not green as it already accounts for approximately 2& of the world's electricity consumption, and it is predicted that it will rise. Determine if use of IT often reduces environmental impacts or not. Yes it does, because if something was electronically saved, it can save paper. Moreover, It has been said that there are less carbon emissions produced when music is downloaded of the web, rather than bought in CD stores, because you don't need to use CDs.

Authentication- Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords. Knowledge of the password is assumed to guarantee that the user is authentic. Each user registers initially (or is registered by someone else), using an assigned or self-declared password. Tokens- A Hardware Token is an Authenticator in the form of a physical object, where the user's interaction with a login system proves that the user physically possesses the object. Hardware Tokens authenticate users on the basis that only the Token assigned to the user could have generated the pseudo-random number or code response keyed in by the user. Successful entry of this code implies that the user is in physical possession of the Token. This implies that the user does not allow users to use his Token, and has not lost it. It is use to prove one's identity electronically, and it is small enough to put it in the pocket or attach to keychain. Smart Card-A card with an embedded computer chip on which information can be stored and processed. It is a plastic card about the size of a credit card, with an embedded microchip that can be loaded with data, used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use. Biometric- Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes.

Define: AWS Iaas Define and describe: Free redundancy rapid scalability server failover maintainability Explain each lesson and determine whether you agree or not with each one. May 13 az

1) Define: AWS- The Amazon Web Services (AWS) are a collection of remote computing services (also calledweb services) that together make up a cloud computing platform, offered over the Internet byAmazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3. Iaas - infrastructure-as-a-service; a way to deploy a less reliable server, quickly and without human intervention. 2) Define and describe: Free redundancy- re-deploying your application in another data center or cloud service using on-demand resources instead of having an idle redundant data center. Rapid scalability- Scalability approach that doesn't require access to AMIs that is stored on S3 or EBS. Instead, it uses the on-demand resources. This is when the system can withstand changes in transaction volume without major changes. Server failover- Virtual servers fail more frequently that physical servers, and when they do, there is less ability to recover them. Treat server failover the same way as scalability, just bring up a new server. Maintainability- Use a fully automated deployment and not a server configuration that is created manually to make it maintainability. Since, when a server configuration that is created manually and saved to a "golden image" has numerous problems such as: only the person who built it knows what is there, so if that person is gone, it can be time consuming to re-configure it. On the other hand, a fully automated deployment is not only a maintainable process, it also serves as documentation. 3) Explain each lesson and determine whether you agree or not with each one. Wrong lesson #1 The lesson where the infrastructure of the cloud is either not ready for its time to shine, or never will be. This is the lesson that explains that the infrastructure is still carried out on physical servers, just in remote areas where they are held in the physical data center in large numbers. These physical server
