Why Kubernetes Is the New Application Server
It is hard not to build this impression of containers.  Worse, it seems that the docker image format is massive compared to what most war files were like.  This is annoying not just in terms of raw bytes to move around, but in taking stock of what is getting moved around.<p>My team originally pitched how docker solved much of the dependency upgrade management by having layers for each major set of dependencies.  That ignored the fact that upgrading a layer is not really something you do.<p>So, then you can go around the path of coordinating many containers communicating with each other.  That works, but in that world, things really don&#x27;t seem any easier than the earlier alternatives.  Harder, in many ways.<p>Don&#x27;t get me wrong, the momentum and raw money being put into containers certainly paints it as the future.  It just feels like lying to say that they have even come close to parity with what we were capable of not that long ago.
