1 2 ——————————————————— Split Line —————————————————————- The problem with MySQL is actually due to a series of soft rib decisions, so we have to use middleware or other solutions to solve, including: Make a choice between forcing constraints and transactional and full-text indexing (InnoDb vs MyISAM) It is not easy to "impersonate" a transaction in the client code Inconsistent DB states are easy to obtain without enforcing constraints If there i

As of the SQL Server 2008 R2 version, Microsoft has not yet launched an official load-balancing component that can be DIY only through other technical features of SQL Server or by using Third-party components. In previous articles, the small series also summarized some common "SQL Server cluster" SQL Server Data Synchronization "SQL Server Failover" ... and other related implementation techniques. It's not

server load balancer system. You do not need to interrupt the running of your application. Therefore, seize this opportunity. Of course, the cost is that this requires a little more complexity during application development. This is the content to be covered in this article. Then you may say to yourself, "but how do I know I am using server load balancer ?". The

However, the customer's requirements are unlimited. In the past two days, the customer hoped that we could support both HTTP and T

transparent.It also reduces the reliance on the F5 hardware load balancer by obtaining a list of service provider addresses in the consumer, which can reduce the partial cost.(2) When further development, inter-service dependencies become a complex, even unclear which application to start before which application, the architect can not fully describe the application's architectural relationship.At this poi

If Nginx does not only have to proxy a server, it is not as hot as today, Nginx can be configured to proxy multiple servers, when a server down, can still keep the system available. The specific configuration process is as follows:1. Under the HTTP node, add the upstream node.Upstream LINUXIDC {Server 10.0.6.108:7080;Server 10.0.0.85:8980;}2. Configure the Proxy_pass in the location node under the server node to be://+ upstream name, i.e. "HTTP://LINUXIDC ".Location/{root HTML;Index index.html i

In the past, when running a large web application, it was necessary to run a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the "Large server" model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies.The advantages of "more small servers" over the "l

The interviewer is always fond of asking some questions about Server Load balancer. I don't know if they are really involved or self-satisfied. I just want to say, when you deny others' ideas, whether it is better to seriously consider others' ideas than yours. This means that multiple users request services. The server is a cluster, and a layer of load balancing
