+## [Release the first version of Apache - 2.4.0] Make API Gateway Simple
+
+> Disclaimer: In this article, `Apache ShenYu` refers to `Apache ShenYu (incubating)`
+> Author: Xiao Yu Apache ShenYu(incubating) Founder && PPMC
+> 2.4.0 Release Manager: Zhang Yonglun Apache ShenYu(incubating) PPMC && Apache ShardingSphere PMC
+
+The `Apache ShenYu` gateway is renamed from the original `Dromara/soul` gateway after donated to the `Apache` foundation.
+The `2.4.0` version released this time is the first version after the `Apache ShenYu` gateway enters the `Apache Incubator`. This version involves many new features,The project name, package name, and `maven` coordinates are changed.
+
+## What Is Apache ShenYu?
+
+`Apache ShenYu` is developed using the `Java reactor` programming method, and is an `API gateway` with features such as `asynchronous`, `high performance`, and `cross-language`.
+In terms of flow control, there is an exquisite Admin console, which can `precise` and `dynamic` control flow to meet complex business scenarios.
+In terms of functions, it uses plug-in design ideas and supports many common protocols: such as `http/https`, `Dubbo`, `Spring Cloud`, `gRPC`, `Motan`, `Sofa`, `Tars`, etc.
+And built-in very rich function plug-ins, such as `circuit breaking`, `current limit`, `authentication`, `access control`, `firewall`, `monitoring`, `parameter change` and so on. Its architecture diagram is as follows:
+
+ 
+
+## Flow Control
+
+The control of flow is the soul of the gateway. For flow control, `Apache ShenYu` has designed two concepts of `selector` and `rule` to control the flow.
+
+`Selector` and `Rule` are the most soulful things in the `Apache ShenYu` gateway. Master it, you can manage any traffic.
+
+A plug-in has multiple selectors, and a selector has multiple rules. The selector is equivalent to the first-level screening of traffic, and the rule is the final screening.
+
+For a plug-in, we hope that according to our configuration, the plug-in will be executed only if the traffic meets the conditions.
+
+The purpose of selectors and rules is to allow traffic to perform what we want when certain conditions are met. This kind of rules must first be understood.
+
+The plug-in, selector, and rule execution logic are as follows. When traffic enters the Apache ShenYu gateway, it will first determine whether there is a corresponding plug-in and whether the plug-in is enabled; then it will determine whether the traffic matches the plug-in's selector.
+
+Then determine whether the traffic matches the rule of the selector. If the requested traffic meets the matching conditions, the plug-in will be executed, otherwise the plug-in will not be executed and the next one will be processed.
+
+This is how the Apache ShenYu gateway completes flow control through layers of filtering. The flow chart is as follows:
+
+<img src="/img/shenyu/plugin/plugin-chain-execute-en.jpg" width="80%" height="70%"/>
+
+## Traffic filtering
+
+Traffic filtering is the soul of `selectors` and `rules`, corresponding to the matching `conditions` in the selectors and rules. According to different traffic filtering rules, we can handle various complex scenarios.
+
+Traffic filtering can obtain data from Http requests such as `Header`, `URI`, `Query`, `Cookie`,
+
+Then you can use `Match`, `=`, `SpEL`, `Regex`, `Groovy` and other matching methods to match the data you expected.
+
+You can use the matching strategy of `And/Or` to add multiple sets of matching. The above are all using `SPI design ideas`, users can `self-expand`: For more, please see: https://shenyu.apache.org/projects/shenyu/selector-and-rule/
+
+The process diagram is as follows:
+
+
+
+## Data synchronization and caching
+
+In order to improve the `performance` of the gateway, the `Apache ShenYu` gateway will cache all flow control rules in the `JVM` memory.
+
+In the `cluster deployment/distributed` scenario, `Apache ShenYu` independently developed a set of Remote synchronization of Admin console data to the JVM memory of each Apache ShenYu gateway node.
+
+Each scheme adopts the design idea of SPI, so that users can choose flexibly. Currently supported schemes are `HttpLongPull`, `Websocket`, `Zookeeper`, `Nacos`, `Consul`, `ETCD`.
+
+The overall process is as follows:
+
+
+
+## Admin console
+
+In order to facilitate the user to quickly and conveniently control the flow and all the functional characteristics of the gateway, `Apache ShenYu` provides a very beautiful `Admin console`, the user can `Chinese and English switch`, on this, you can freely `control the flow` , `Start-stop plug-in`, `Configure different parameters and strategies`, these operation changes are synchronized to the gateway's `JVM memory` through the aforementioned `data synchronization principle`. The backgr [...]

+
+##### Menu/data permissions
+
+The background management of the gateway is agent. For enterprise-level users and cross-departmental applications, `Apache Shenyu` designs a common `authorization control system`, including `button level menu permissions`, and `row data level data Permissions`. And these permissions are automatically configurable by the `administrator`.
+
+<img src="/img/community/admin-permission-en.jpg">
+
+## Protocol Proxy
+
+Protocol proxy is the core function of the gateway. Currently `Apache ShenYu` supports `http` to `http/https`, `Websocket`, `Dubbo`, `Spring Cloud`, `gRPC`, `Motan`, `Sofa` The conversion of protocols such as `Tars`, etc. will support `TCP`, `MQTT`, `MQTT` and other protocols in the future.

+* Custom plug-ins are dynamically loaded, which is convenient for users to expand and update quickly and without stopping.
+* Comprehensive coverage of integration testing and unit testing.
+
+## Community
+
+`Apache ShenYu` is an autonomous community open source project completely dominated by Chinese people. It is currently in a period of rapid development.
+`Function development`, `Complete documentation`, `fix BUG` and many other things need to be completed.
+The `Apache ShenYu` community follows the community philosophy of `Apache Way` and creates a `completely open` and `government` community. Every half month, a full community meeting will be held, and the community’s committers, contributors, and users will participate in it ,
+At the meeting, everyone can speak freely and put forward their own views and opinions, such as discussing different functions and different codes, and it is best to reach a consistent point of view.
+In the Apache ShenYu community, we respect the principle of communication priority of mailing list> Github Issue> WeChat group.
+The main purpose is to keep a record of every problem, no point of view, so as to better help others, so as to promote the sustainable development of the community.
