First, it destroys the service stateless feature. In order to ensure the security of the external services, we need to implement the access control of the service, and the Open service control mechanism will run through and pollute the entire open services business logic, this will bring the most direct problem is that the service cluster of the rest API stateless features. From the
MicroServices architecture, usually a business system will have a lot of microservices, such as: OrderService, Productservice, UserService ..., in order to make the invocation more simple, usually in the front end of these services to encapsulate a layer, similar to the following:In front of this layer is commonly known as "Gateway layer", its existence significance is that the "1 to N" problem into the "1 to 1" problem, while the request to the real
Some websites running on Nginx sometimes appear as "502 Bad Gateway" errors, some times even frequently. The following is a small compilation of some of the Nginx 502 error troubleshooting Methods for reference:
The reason for the Nginx 502 error is more due to a problem with the backend server in Agent mode. These errors are generally not nginx itself problem, must look for the reason from the back end! But nginx all these mistakes in their own body

this time, Nginx cannot transfer the PHP file to PHP-FPM processing, so the CPU will be reduced to very low (not to handle PHP, not to execute SQL), and the load will rise to very high (close and open children, nginx wait php-fpm), the network card traffic is also reduced to very low ( Nginx cannot generate data transfer to client)Solving the problem is simple, increase the number of children, and set max_requests to 0 or a larger value, restart PHP-FPMThe implication of Nginx 504
