cache deployed in a cluster of multiple servers, providing the caching service as a cluster. One is the distributed cache, which is represented by JBoss cache, which needs to be updated synchronously, and one is a distributed cache of non-communication represented by memcached.Memcached design simple, excellent performance, complementary communication server cluster, massive data scalable architecture another site architects flock to. Asynch

NET site architecture time (eight) testIn general, the overall test strategy is: the performance and stress test for some systems, the peak processing performance of each part, and then simulate the overall process testing, at this time not to follow the peak run, focus on testing the overall business process and business expected load.After defining the test strategy for each part, the specific tool use selection is not the main problem.1, differen

For server monitoring I recommend using the cacti software. The server is configured with a dual network card, an intranet, an extranet. Increase the SNMP protocol on the Internal network card, and then add the servers that need to be monitored in the cacti. To cacti an extranet IP, you can view the status of the server through the

In fact, even if you use Java to build a web application that is not very cumbersome, it is not easy. There are many things to consider at the beginning of the architecture. From a high point of view, there are many questions for developers: How to Establish user interfaces? Where can I process the business logic? How to persist data. In this three-layer architecture

The MVC pattern is very common in the site architecture. It allows us to create a three-tier application that separates useful layers from the code, helps designers and developers work together and improves our ability to maintain and extend existing programs.
