Where do you start to develop cloud computing applications?

2009 years of Cloud computing still continues its heat in the 2008, and it is not difficult to predict that the application running on the cloud (hereinafter referred to as cloud applications) is bound to be more and more, and that there will surely be a growing number of developers who have to consider or participate in the development of cloud applications. The essence of cloud computing is access to applications and services over the Internet, which are often not run on their own servers but are provided by third parties. For cloud developers, in cloud computing mode, while deploying applications without concern for infrastructure issues, it also brings new problems, such as opening ...

Database research in cloud computing era

Introduction with the advent of the cloud computing era, various types of Internet applications are emerging, the relevant data model, distributed architecture, data storage and other database related technical indicators also put forward new requirements. Although the traditional relational database has occupied the unshakable position in the data storage, but because of its inherent limitation, has been unable to satisfy the cloud computing age to the data expansion, reads and writes the speed, the support capacity as well as the construction and the operation cost request. The era of cloud computing has put forward a new demand for database technology, which is mainly manifested in the following aspects. Mass data processing: to ...
