什么是surging

surging从中文译义来说，冲击，汹涌，也可以翻译成风起云涌。我所希望的是.net core 能成为最流行的技术。

surging从技术层面来说就是基于RPC协议的分布式微服务技术框架,框架依赖于Netty 进行异步通信,采用Zookeeper作为服务注册中心，集成了哈希，随机和轮询作为负载均衡算法 1.服务化应用基本框架

框架的执行过程如下：

1.服务提供者启动，根据RPC协议通过配置的IP和port绑定到netty上

2.注册服务信息存储至Zookeeper

3.客户端CreateProxy调用服务时，从内存中拿到上次通知的所有效的服务地址，根据路由信息和负载均衡机制选择最终调用的服务地址，发起调用 2.简单示例 

  创建IModuleServices

   IUserService.cs:

  [ServiceBundle]  //服务标记
   public interface IUserService
   {
        Task<string> GetUserName(int id);

        Task<bool> Exists(int id);

        Task<int>  GetUserId(string userName);

        Task<DateTime> GetUserLastSignInTime(int id);

        Task<UserModel> GetUser(int id);

        Task<bool> Update(int id, UserModel model);

        Task TryThrowException();
    }

 创建领域对象

 UserModel:

   [ProtoContract]
    public class UserModel
    {
        [ProtoMember(1)]
        public string Name { get; set; }

        [ProtoMember(2)]
        public int Age { get; set; }
    }






 AssemblyInfo.cs，扩展AssemblyModuleType来标识模块，根据AssemblyModuleType进行相关规则的反射注册






 [assembly: AssemblyTitle("Surging.IModuleServices.Common")]
 [assembly: AssemblyDescription("业务模块接口")]
 [assembly: AssemblyModuleType(ModuleType.InterFaceService)]





// 如果此项目向 COM 公开，则下列 GUID 用于类型库的 ID
[assembly:]








创建Domain Service



PersonService.cs



[ModuleName("Person")]  //标识实例化名称



        public Task<string> GetUserName(int id)
        {
            return GetService<IUserService>("User").GetUserName(id);
        }






        public Task<bool> Exists(int id)
        {
            return Task.FromResult(true);
        }






        public Task<int> GetUserId(string userName)
        {
            return Task.FromResult(1);
        }






        public Task<DateTime> GetUserLastSignInTime(int id)

        public Task<UserModel> GetUser(int id)

            return Task.FromResult(new UserModel
            {
                Name = "fanly",
                Age = 18
            });
        }






        public Task<bool> Update(int id, UserModel model)
        {

            services.AddLogging();
        }






    }
 }










远程服务调用




 ServiceLocator.GetService<IServiceProxyFactory>().CreateProxy<T>(key)










本地模块和服务调用




 ServiceLocator.GetService<IServiceProxyFactory>().CreateProxy<T>(key)









5.负载均衡



surging提供3种负载均衡方式:



Random:随机，调用量越大分布越均匀，默认是这种方式



Polling:轮询，存在比较慢的机器容易在这台机器的请求阻塞较多



HashAlgorithm:一致性哈希，对于相同参数的请求路由到一个服务提供者上。
6.其他功能



surging还会提供分布式缓存，AOP数据拦截，基于rabbitmq订阅发布, 监控服务，后续完善后再来讲解。
6.性能测试



测试环境



CPU:Intel Core i7-4710MQ



内存：16G



硬盘：1T SSD+512G HDD



网络：局域网
测试结果如下：
1万次调用，也就2290MS，平均单次也就0.229毫秒，性能不错。
7.总结
surging 0.0.0.1版本的发布意味着分布式微服务已经走出了第一步，以后还有很多工作需要完善。我会花很多空余时间去完善它。如果大家还有任何疑问或者感兴趣的话，可以加入QQ群：615562965
