未來的cloud native

  https://blog.cimicorp.com/?p=4251 if the market is heading to cloud-native, you can’t differentiate your cloud-native approach by adopting the same tools as everyone else. >>要賺錢活命的要多想想 Despite the way the market has talked about the cloud and cloud-native, it’s always been really a development issue The cloud has features that the typical data center doesn’t have.   The application was  written  to run in the cloud, not moved there from somewhere it was already running. "The central adaptation of components to cloud-native status is making them into microservices, which are stateless (in some way) features that can be spun up and run, taken down, moved, and so forth, as conditions demand.  Having a bunch of application features floating out there in the ether isn’t exactly how most application developers think, and the tools to make this work start with an abstraction of connectivity, or virtual connection fabric .  That’s what service meshes provide." >> 但這讓se
