Quantum Computing(QC):
Cloud is a cause for rain, Cloud Computing is cause for new revolution in the next era. It is applicable only to daily users of computer, banking, accounting etc., Today if we start to use internet, within less than a second you will get the result. Means Internet is fast* its all about the bandwidth and the Optical fiber(OF) communication, on which people are working 24/7. Sometimes even 100Mbps speed will become very slow in front of some good applications. So people are thinking in a new way to increase the speed.
First will come Cloud Computing using softwares or you may say working server.
Second one Scientific people are thinking to pass 100% light through OFC(optical Fibre Cable) till now we are able to pass 68% in low cost. But last year Nobel Prize shared for Optical Fibre Communication in which he passed 98.99% of light, but that technology is costly and we cant use it for applications.
Third one is Wireless Communication: Which comes out from the Transmitter and received by receiver. Essential is again OFC without that no signal can travel in air. Difficult one, people are trying more. Nowadays imagination has crossed the limits, research groups are making electrons to travel in the air. If it became possible next 10 Nobel prizes are for Physics.
So todays topic begins here,
Quantum Algorithm makes Quantum Computer. Which works equally with Supercomputer(India has three one in IISC). According to Tathagat's research papers Quantum Algorithms are the new way for searching or search engines.
Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories:
Infrastructure-as-a-Service (IaaS),
Platform-as-a-Service (PaaS) and
Software-as-a-Service (SaaS).
The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.
A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, typically by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as improved access to high-speed Internet and a weak economy, have accelerated interest in cloud computing.
A cloud can be private or public. A public cloud sells services to anyone on the Internet. (Currently, Amazon Web Services is the largest public cloud provider.) A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services
Infrastructure-as-a-Service like Amazon Web Services provides virtual server instances with unique IP addresses and blocks of storage on demand. Customers use the provider's application program interface (API) to start, stop, access and configure their virtual servers and storage. In the enterprise, cloud computing allows a company to pay for only as much capacity as is needed, and bring more online as soon as required. Because this pay-for-what-you-use model resembles the way electricity, fuel and water are consumed, it's sometimes referred to as utility computing.
Platform-as-a-service in the cloud is defined as a set of software and product development tools hosted on the provider's infrastructure. Developers create applications on the provider's platform over the Internet. PaaS providers may use APIs, website portals or gateway software installed on the customer's computer. Force.com, and GoogleApps are examples of PaaS. Developers need to know that currently, there are not standards for interoperability or data portability in the cloud. Some providers will not allow software created by their customers to be moved off the provider's platform.
In the software-as-a-service cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. SaaS is a very broad market. Services can be anything from Web-based email to inventory control and database processing. Because the service provider hosts both the application and the data, the end user is free to use the service from anywhere.
Why Google search engine is in top position from long years. They are having new technologies with respect to time.I am not saying Microsoft's Bing is not having. If we compare with Google then its not. I may say Google adapted Cloud Computing, for its users. But Company has not disclosed any matter regarding this, its because of competition in business. One example,Google is launched new browser Google Chrome, big firms are not worried about browsers, they are worried about search engines. As Mozilla if we would have used, it will ask for add-ins. But the Chrome doesn't asks.The speed changes in both. Chrome is faster.
It may be difficult for Google, Its user, if surfing from any other browser they might have faced the problem to fix the target in Cloud. So its easy way for them to fix the target (Whatever it may be). According to me Big Browser took birth "Google Chrome". If you open Google page it will ask you to install for next uses(No conditions to install). For them it will be the clear road in that we can ride or bike till up to 100Km/Hour. If road is not good, we are having good bike in hand, we cant give the satisfaction to our vehicle. For them, they created good road, choosing bike is your option.
Long one this time, future no posts on CC.
