Analysis is the core of all enterprise data deployments. Relational databases are still the best technology for running transactional applications (which is certainly critical for most businesses), but when it comes to data analysis, relational databases can be stressful. The adoption of an enterprise's Apache Hadoop (or a large data system like Hadoop) reflects their focus on performing analysis, rather than simply focusing on storage transactions. To successfully implement a Hadoop or class Hadoop system with analysis capabilities, the enterprise must address some of the following 4 categories to ask ...

Before 2013, there may be a wait-and-see or scepticism about the cloud, but after a year of development, cloud computing has completely landed: Big companies are busy with how to deliver faster, more stable and safer cloud services, how to snatch users in the cloud market, and small companies to consider how to use cloud computing to reduce their operating costs. How to make your system into a cloud structure; startups think about how to use the cloud to reduce upfront spending, and even how to use the concept of "cloud" to start a business and sell yourself in front of a VC. According to Gartner, 2013 Global ...

"Openness" is also a new term in the field of technology. It may sound like "open" or "closed", but some technical experts believe that openness is simply a popular word, and that there is not much real value to customers. In this article, we will explore the differences between marketing terminology and reality in the open cloud domain. To arrive at a precise conclusion, we first need to define the term exactly. We first need to understand the meaning of "open". Open Cloud is not the same thing as open source cloud. Open source refers to a software licensing model. In fact, the free feature of open source software is not the customer's most concern ...

In the past, we have introduced some principles of software development, such as the 10 commandments of high quality code and the UNIX design principles described in the UNIX legend (next article). I believe that you can learn from middle school some knowledge of design principles, as I said in the "How Do I Recruit procedures", a good programmer usually consists of its operational skills, knowledge level, experience level and ability four aspects. Here I would like to talk about some of the principles of design, I think these things belong to the long-term experience summed up knowledge. These principles should be understood by every programmer. But...

Are the legal uncertainties about APIs and fair use going to impact the cloud computing market? Now, when it comes to intellectual-property issues, it is a bit of a bore-even when technology giants are dealing with the courtroom. However, copyright cases between Google and Oracle have allowed cloud computing to change concerns about the impact of the event. The problem is the copyright of the Oracle Java Application Interface (API), which accuses Google of embezzling 37 of them into the Android operating system. In Monday, a jury in California concluded that part of the ruling was that Google violated Oracle ...

The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...
