Some time ago, the project planned to establish an independent logon Authentication center. Because a set of stable logon and Authentication code was developed separately, the final solution was to apply the Central Authentication Service (CAS) to the open-source Authentication center) for adaptive modification.

Introduction to Redis:First, IntroductionRedis is an open source, Key-value database that is written in C and that supports network interaction and can be persisted based on memory. Redis source code is very simple, as long as there is time to see rectification C language, to see the source of Redis can read 50-60%. The current largest cluster of Redis should be Sina. Redis is currently supported by Vmvaer, and many of the open source software needs t

Mongodb distributed cluster (2. Replica set) and mongodb cluster copyOverview
Replica set is a type of master-slave replication. It is a master-slave replication that comes with the Failover function. It solves the disadvantages of the master-slave replication and does not require human intervention when the master server fails, the system automatically selects a new master server.

Java EE
Cluster Generally speaking, Java EE cluster technology includes "load Balancing" and "failover" two parts. In the above illustration, load balancing means that a target object is requested by many client objects simultaneously. The load balancer is between the caller and the callee, and you can distribute the request to a target object with the same functionality but different locations. Both hig
