SignalR-ScaleOutCarter Ho2 Minutes2019年5月3日

• 當VM達到承載數量上限後必須另開VM做附載平衡，Signalr也不例外
  
• Signalr實作ScaleOut目前有三種方式
  • Azure ServerLess
  • Redis
  • MsSql
    
• 以Redis實作為例

  //// 參考Nuget
  Microsoft.AspNet.SignalR
  Microsoft.AspNet.SignalR.Core
  Microsoft.AspNet.SignalR.StackExchangeRedis
  Microsoft.AspNet.SignalR.SystemWeb
  Microsoft.Owin
  
  //// Startup.cs
  [assembly: Microsoft.Owin.OwinStartupAttribute(typeof(RedisScaleOut.Startup))]
  namespace RedisScaleOut
  {
      using Microsoft.AspNet.SignalR;
      using Owin;
  
      public partial class Startup
      {
          public void Configuration(IAppBuilder app)
          {
              GlobalHost.DependencyResolver.UseStackExchangeRedis(new RedisScaleoutConfiguration("redisConn", "redisAffixKey"));
  
              app.MapSignalR();
          }
      }
  }
