Mistaken identity Service A listens on 10.0.0.1:30000 over HTTP.
Microsoft Build 2017 6/24/ :43 AM Mistaken identity Service A listens on :30000 over HTTP. Client resolves Service A and gets address :30000 Service A moves to a different node. Service B is placed on and coincidentally uses the same port: Client attempts to connect to service A with cached address :30000. Client is now successfully connected to service B not realizing it is connected to the wrong service. How does the client know to re-resolve the address for service A? © Microsoft Corporation.

Microsoft Build 2017 6/24/ :43 AM Recommendations WebListener: Use for Internet-facing fixed-port stateless services. URL path and hostname routing features can be useful for hosting multiple web applications in the same cluster. Provides DoS protection. Windows authentication and other IIS features. Kestrel: Use for internal service communication. Much simpler service resolution. No URL registration required. Very fast. © Microsoft Corporation. All rights reserved.
