The actual drawbacks (the author has chosen to ignore them): - less secure - you still have to update the system images and redeploy a lot (its made for that so its fine). you cant just spin an image and stop caring for it. libraries will update and potentially breaking ur app because u know, performance, sec fixes, the usual - docker itself is not very nicely made, hard to debug etc. hopefully will get fixed over time. what is actually does better? its faster.. not 26:1 but it is faster obviously. mainly, you dont have to preprovision vms since there is no boot time. so you can deploy fast. its also providing a much needed API/glue for all the things.
