background information Consul is a service grid solution. Consul KV, one of its cores, is a distributed key value database, which is mainly used to store configuration parameters and metadata, and also allows users to store index objects.In the microservice architecture mode, when the upstream service changes due to capacity expansion and hardw ...

This paper introduces the characteristics of Apache apisid and GraphQL, and how to use Apache apisid, an API gateway, to proxy GraphQL requests, and puts forward a solution to the pain points of the actual scene.background information GraphQL is an open source, API oriented data query operation language and corresponding running environment. Or ...

1. Introduction The gateway is the common entrance for all requests, so the current can be limited in the gateway, and there are many ways to limit the current. The current limit of the gateway is realized through sentinel component. Sentinel supports current limiting for spring cloud gateway, Zuul and other mainstream gateways. The curre ...

@TOC Insert code slice here Recently joined a company that built it from scratch. The rpc framework is motan. The reason why motan is used is mainly because the company is divided into two teams: java and php. motan can realize cross language call and is relatively lightweight, so motan is selected. Since rpc is used for communication between ...

It provides unified, high throughput and low latency features for processing real-time data.Its persistence layer is essentially a "large-scale publish / subscribe message queue according to the distributed transaction log architectur ...

With the rise of micro service architecture, maintaining service security has become more challenging than before. Multiple back-end server instances using a single static key to access the database server will bring huge risks. If the key certificate is leaked, the whole system will be affected. In order to solve the impact of key certificate ...

CSRF (Cross Site Request Forgery), that is, cross site request forgery. The key point of launching cross site request forgery attack is to make the target server unable to distinguish whether the source of many requests is a real user or an attacker. The general process of attack is as follows: first, the attacker will induce the user to naviga ...

Open Policy Agent (OPA) is an open source lightweight general policy engine, which can replace the built-in policy function module in the software to help users realize the decoupling of service and policy engine. Benefit from OPA Perfect ecosystem , users can easily integrate OPA and other services, such as program library, HTTP API, etc. As ...
