Any Organization Can Use Cloud Computing

Payment for Cloud Computing services is usually on some incremental basis. In other words, you pay for only what you use. This works for organization of most any size. It is possible that for smaller organization, Cloud Computing will allow the use of software that would normally be prohibitively expensive if the organization had to buy it and install it on their own server. For very small organizations, it might be possible to find Cloud Computing services that are free for low levels of usage.

Blurring of Services

It is possible to assemble a service-oriented architecture (SOA) that uses services from multiple Cloud providers along with services provided by systems internal to an organization. This results in a blurring of where the services actually reside. In fact, most often it does not matter where they reside for functionality. Location of services are often dictated governance issues such legal or security concerns, as opposed to technical issues.

Basic types of Clouds in Cloud Computing:

  • Private Cloud

  • Public Cloud

  • Hybrid Cloud

Variations on the basic types of Clouds in Cloud Computing:

  • Virtual Private Cloud

  • Community Cloud

Basic terms and concepts of mobile technology

Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. Tablets are available on the 3G and 4G networks.

4G Networking[edit]

One of the most important features in the 4G mobile networks is the domination of high-speed packet transmissions or burst traffic in the channels. The same codes used in the 2G-3G networks are applied to 4G mobile or wireless networks, the detection of very short bursts will be a serious problem due to their very poor partial correlation properties. Recent study has indicated that traditional multilayer network architecture based on the Open Systems Interconnection (OSI) model may not be well suited for 4G mobile network, where transactions of short packets will be the major part of the traffic in the channels. As the packets from different mobiles carry completely different channel characteristics, the receiver should execute all necessary algorithms, such as channel estimation, interactions with all upper layers and so on, within a very short period of time.

Operating systems[edit]

Many types of mobile operating systems (OS) are available for smartphones, including: Android, BlackBerry OS, webOS, iOS, Symbian, Windows Mobile Professional (touch screen), Windows Mobile Standard (non-touch screen), and Bada. Among them most popular are the Apple iPhone, and the newest – Android. Android is a mobile operating system (OS) developed by Google. Android is the first completely open source mobile OS, meaning that it is free to any cell phone mobile network.

Since 2008 customizable OSs allow the user to download applications ("apps") like games, GPS, Utilities, and other tools. Any user can also create their own Apps and publish them e.g. to Apple's App Store. The Palm Pre using webOS has functionality over the Internet and can support Internet-based programming languages such as Cascading Style Sheets (CSS), HTML, and JavaScript. The Research In Motion (RIM) BlackBerry is a smartphone with a multimedia player and third-party software installation. The Windows Mobile Professional Smartphones (Pocket PC or Windows Mobile PDA) are like that of a personal digital assistant (PDA) and have touchscreen abilities. The Windows Mobile Standard does not have a touch screen but uses a trackball, touchpad, rockers, etc.
