It starts with "we believe Linux containers are the first practical virtualization technology for the embedded world" but then the case for containers vs normal virtualization struggles:<p>"(VMs) [...] have two major drawbacks. The first, and most obvious, is the overhead required to run them. Embedded devices have limited storage space, computing power, and bandwidth, and increasing these resources to handle unnecessary overhead increases the per-device cost without adding any real benefit.".<p>They probably know that VMs don't really take any more storage space, computing power or bandwidth than containers. Maybe a little bit on the computing power side, but the overhead is insignificant.<p>Also the big selling point is "Isolated application failures" but there is no mention of security failures. Docker style containers aren't very strong on the security front.
