Re: Nate Amsden Re: containers are the future

".....Containers have their use cases...." Definitely, as in "what is the cheap way to stack existing hard systems?" They cannot replace hypervisored VMs for one very simple reason - containers share far too much of the underlying OS to ensure one container misbehaving cannot affect other containers. Sure, they claim they can by portioning out disk I/O, RAM, CPU time, etc., but VMs using individual OS instances are therefore more resilient and will always be more attractive for high-availability solutions. Pottie mentioned Slowaris Constrainers (sic), maybe he should read the following Oracle best practices for RAC as it points out very early on that real HA and containers means dumping all the stacking advantages of containers; "....Provision one Oracle Solaris Container per node or server....." - http://www.oracle.com/technetwork/articles/systems-hardware-architecture/deploying-rac-in-containers-168438.pdf
