Generally, the performance of a single crawler is limited, and a sufficient number of related webpages cannot be crawled within a reasonable time range. Therefore, in practice, a distributed crawler is generally designed to allow each crawler node to crawl a website close to it, and then integrate the structure to the user. Distributed Technology Applies to web crawlers, which not only reduces operation costs, but also greatly improves crawler performance. Especially in today's rapid development

── Introduction to distributed computing open-source framework hadoop (I) During the design of the SIP project, we considered using the multi-thread processing mode of task decomposition to analyze statistics for its large logs at the beginning.ArticleTiger concurrent practice-parallel log analysis design and implementation. However, the statistics are still very simple for the time being, so memcache is used as the counter, and access control and s

Cloud computing is a hot topic nowadays, as Ben Pring, a senior analyst at Gartner Consulting, said: "cloud computing has become a hot topic for everyone ".

Regarding the Security protection of Cloud computing data centers, CSA (Cloud Security Alliance, Cloud Security Alliance) put forward a total of eight suggestions in D7 of the Cloud computing key field construction guide, four security risks related to network security are recommended:  Cloud service providers provide the right to obtain the commitment or authorization to audit customers or external third

First, let's take a look at the Classic views of masters on cloud computing: When talking about "the past, present, and future of Computer Science" in, Bill Gates said: "users only need KB of memory ." At that time, allProgramAll are very small, and MB hard disks are useless. Lee Kai-Fu (currently vice president of Google worldwide and president of China) made a metaphor: Qian Zhuang. At first, people put money under their pillows, and later they

In actual information systems, a lot of data computing is performed for front-end display. Reports are the most common form. These computing implementation processes are often not simple, and it is difficult to use SQL or stored procedures, thus affecting the front-end report design. Images. However, the computing capability of the rundry set
