Today's links 08/06/2015: #SSD no panacea for VMs, Hardware X86 #security breach, #Bigdata stream engine

  • SSD no panacea with VM : because of is operational model SSD tend to have poor performance in virtual environment when shared across multiple VM. The authors suggest to isolate and dedicate SSD for each VM in order to benefit from the speed benefit of SSD. Micro storage solution anyone ?
  • X86 design flaw : Apparently there is a way to escalate from ring 0 to the high privileged state. This can be really interesting if this would enable VM or container to escape and gain access to the bare-metal system. : :
  • Heron : the descendant of Storm by Twitter. The architecture seems nice and try to address some of Storm shortcoming.
