What are the application flow restrictions of API gateway framework?

A large Internet company or platform , It always involves a lot of microserver management , Take a company website for example , Member products and order system are part of the website application . Both application access and browser access require access to background services , In this series of visits from different access ports , There will be some problems that need to be repeated , therefore api Gateway framework It came into being. .

api Application of gateway framework

On different microservers , If every server is equipped with a domain name , There will be a series of problems , Lead to inefficient maintenance and access . and api The role of the gateway framework arises , By using the same gateway portal , The same gateway can be used as all traffic portals . Forward the access requests from different portals to the server , Thus saving time , And it can complete a series of follow-up operations efficiently and quickly . The role of the gateway is not just forwarding , You can also extend a series of functions .

What are the current limiting types ？

I understand api Application of gateway framework , Let's take a look at several forms of current limiting for enterprise applications under different circumstances . Current limiting can be divided into single machine current limiting , This single machine has high current limiting performance , No remote calls are involved . Another current limiting method is distributed current limiting . Distributed current limiting requires a node to maintain the current interface . When some large-scale enterprises apply hierarchical flow restriction when the traffic is too high , It will ensure the overall stability of the system , Avoid the overall collapse of the whole system due to inadequate current limiting .

That's all api The application of gateway architecture . Gateway is the access port for all services , Therefore, the stability of a gateway is very high , In general , Stability requirements are higher than other service systems .
