Background simulation: there is a electric business platform is developed, compiled packaging, online operations, as the market is fast changing, the original discount system design cannot have satisfied the demand of now, if do not change the economy will bring to the company at any time, now need to modify the program logic, but the question comes, is doing sales promotions, system traffic cannot interrupt the existing service, even 30 will bring to the company irreparable loss,

My question:

1. How early in the design of this system to solve the problems behind
2. How to design a flexible discount system
3. In the case of not restart adaptation compiled languages how internal logic operation

CodePudding user response:

Micro service available?

CodePudding user response:

1, a more experienced architects can avoid the problem of system in the late more
2, discount system provides the internal extension interface, just add the code to achieve functional changes as far as possible, rather than directly modify the source code
3, hot deployment, double machine hot standby
