CLOUD COMPUTING

Cloud Computing

Introduction

Integrated online services such as Google, Amazon, IBM Blue Cloud, Sales force and Microsoft's Azure have become a future trend of shared data center, accessible, secure and scalable for companies at a cost like any other service. The easiest way to that you return the comprehension from this page and you might want to know more, I illustrate one possibility is that the concept of cloud computing. Take for example your word processing software.

It is in most of the SCAS Microsoft Word or Open Office sometimes. In short, it does not matter! What concerns us is that traditional software is installed on your computer. With cloud computing you connect to the Internet, anywhere, with any computer and you access one hand direct met logical a word processor but also to your entire document stored online.

What is Cloud Computing?

Cloud computing is a concept that is to deport on servers remote processing computer located on the position traditionally Client of the user.

Is a term that is defined as a technology that offers services through the Internet platform, the service users have access to free or pay all depends on the service needed to use.

The term is a trend that responds to multiple integrated features. One example of this "cloud" is the service provided by Google Apps which includes a browser to the storage of data on its servers. Programs should be in the online servers and can access the services and information through internet. (K.E., Trenberth, 1992)



Characteristics of cloud computing

One of the main differences of cloud computing is that there is need to understand the infrastructure behind it, becomes "a cloud" where applications and services can easily grow (scale), running fast and almost never fail, without knowing the details of how this "cloud."

This type of service is paid according to some measure of consumption, not the equipment used by itself, but for example in electricity consumption or CPU / hour as in the case of Amazon EC2. Other features include:

Auto Reparable: Auto Repairable: In case of failure, the last backup of the application automatically becomes the primary copy and generate a new one.

The whole system / architecture are predictable and efficient. If a server handles 1,000 transactions, 2 servers handle 2000 transactions.

Governed by a Service Level Agreement (SLA) that defines a number of policies and what are the expected times of return and in case of peak, you must create more instances. In the case of AWS still wondering if your SLA is appropriate.

Virtualized: Applications are independent of the hardware on which to run, even several applications can run on a single machine or an application can use several machines at once.

Multipurpose: The system is built in such a way that allows different customers to share the infrastructure without worrying about it and without compromising your security and privacy

Examples of Cloud Computing

There are several large companies who are dedicated to providing these services, promoting easy access ...
