design of our services to avoid the availability of multiple versions.is micro-service the future?Our main purpose in writing this article is to explain the main ideas and principles of microservices. But when it comes time to do this, we realize that the MicroServices architecture style is a very important idea: something that deserves serious consideration in enterprise applications. We recently used this style to build a few systems that recognize enthusiasts who also use and like this appro

years, and voluminous information is generated from social networks every day. it is desirable to build an intelligent recommender system to identify what interests users efficiently.The task of KDD-cup 2012 track 1 is to develop such a system which aims to capture users 'interests, find out the items that fit to users' taste and most likely to be followed. the datasets are provided by Tencent Weibo, one of the largest social networkingWebsite in China, is made up of 2,320,895 users, 6,095 item

, Palm uses it, Nokia uses it, and RIM (Blackberry) recently announced it will switch to it. In addition to Microsoft, almost all browsers on smartphones use WebKit. Apple has set standards for mobile Web browsers by enabling its own WebKit technology. Second, let's talk about the "complete Internet 」. Adobe repeatedly said that Apple's mobile devices cannot access the "full Internet" because Flash is used for 75% of videos on the Internet. They did not mention that almost all of these videos ar

, the sparsity of the most widely studied movielens dataset is 4.5%, netflix is 1.2%, bibsonomy is 0.35%, and delicious is 0.046%. From Pearson correlation's calculation formula, if the intersection of two movies is much smaller than that of other movies, the similarity between the two movies is less reliable. From the data sparsity described above, we can see that in the recommendation system, there may be a small number of intersections. This will g

undoubtedly the best system option for gamers.If you want to play some old games (such as 16-bit games), modern Windows architecture often cannot complete the task. Linux supports 16-bit programs through 32-bit and 64-bit systems. This Is due to Wine (Wine Is Not an Emulator), and most Windows applications can run smoothly. Are you going to enjoy new and old games? The dual system helps you solve the problem.2. HostWhen running the operating system in the native mode (unlike virtual machines),

At the end of last year, Netflix published an article entitled "five lessons learned from turning to Amazon Web Services" (5 lessons we 've ve learned using AWS ). Amazon Web Services (AWS) is undoubtedly an outstanding representative of the so-called "cloud computing. Therefore, this article can also be seen as a key suggestion for any website that wants to switch to the "Cloud. Of course, these suggestions are really great! The following is what sho

With the introduction of several core components from the previous spring cloud, we have been able to build a short (imperfect) microservices architecture. As shown in the following example:We implemented service registries and service registration and discovery using the Eureka in spring cloud Netflix, while service consumption and balanced workloads across the ribbon or feign through the spring cloud Config enables the application of multi-environme

starting with version 1.2.0, Spring Cloud Netflix now supports the use of attributes and Ribbon documentation is compatible from Defining Ribbon Clients . This allows you to change the behavior at startup in different environments.The supported properties are as follows and should be prefixed with: NFLoadBalancerClassName: Should be implementedILoadBalancer NFLoadBalancerRuleClassName: Should be implementedIRule NFLoadBalancerPingCla

Performance diagnostics for Linux in 60,000 millisecondsWhen you log on to a Linux server in order to solve a performance problem: What should you check in the first minute?At Netflix, we have a huge EC2 Linux cloud, as well as a number of performance analysis tools to monitor and diagnose its performance. These include Atlas for cloud monitoring, and vectors for on-demand instance analysis. While these tools can help us solve most problems, we still
