This series of articles is a learning record about the fundamentals of azure services development, and because of time constraints, the process of wishing to discuss and explore yourself is from scratch, to be able to develop basic programming for azure services. There may be a very deep topic relative to each topic, and I would like to have time to do it through other articles. 　　The positioning of this series is basically positioning, take 20-30 minutes, download the code first, follow the article, run to get the relevant experience. The previous article is about Azure queue storage, this is about ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

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 ...

In the past few years, relational databases have been the only choice for data persistence, and data workers are considering only filtering in these traditional databases, such as SQL Server, Oracle, or MySQL. Even make some default choices, such as using. NET will typically choose SQL Server, and Java may be biased toward Oracle,ruby, Mysql,python is PostgreSQL or MySQL, and so on. The reason is simple: In the past a long time, the relational database is robust ...

Blockchain is currently a relatively popular new concept, containing two concepts of technology and finance. From a technical point of view, this is a distributed database that sacrifices consistency efficiency and guarantees eventual consistency. Of course, this is one-sided. From an economic point of view, this kind of fault-tolerant peer-to-peer network just meets a necessary requirement of the sharing economy - a low-cost trusted environment.

Page 1th: Why use the IAM in the traditional sense, organizations invest in IAM practices to improve operational efficiency and meet requirements for regulatory, privacy, and data protection: improved operational efficiency The architecture of good IAM technologies and processes automates repetitive work such as user entry, 　　Thus improving efficiency (for example, self-service reset user request password without system administrator using Help desk dispatch system intervention). Compliance Management to protect systems, applications, and information from internal and external threats such as ...

The current network of telecom operators can be divided into three categories, namely, the main business, base operations, long tail and SP business. 　The main business includes the application of SMS, MMS and other telecommunications applications, including the current operators of music, video, animation base and so on, long tail business and SP business mainly includes the Internet class and the application of cooperative class. The main problems of current business system are: vertical construction of main business platform, continuous investment, small amount of existing SP business, low utilization of equipment, inability to share, long tail business development and operation cost is high, can not form effective contribution; Base business respective construction, content cannot ...

The main problems of current business system are: vertical construction of main business platform, continuous investment, small amount of existing SP business, low utilization of equipment, inability to share, long tail business development and operation cost is high, can not form an effective contribution; base business construction, content can not be shared, user information can not be shared. 　　 　　If the traditional business network architecture, these problems can not be fundamentally resolved, and the rise of cloud computing technology has brought us a glimmer of light. Telecom business pooling and virtualization technology has experienced more than more than 10 years of development, technology has been more mature. and Cloud tube ...

Today has entered the web2.0 high-speed development of the internet era, a variety of Internet Web applications have sprung up. So how do you develop a good Web application as a Web developer? There is no simple answer to this question, even the educational institutions may not be able to know clearly. So, like most web developers in this field, we only learned this by doing experiments. No one tells us how to do it, we start by doing something for ourselves, learn how to develop Web applications in this ...
