Re-Think of Virtualization
and Containerization
Hyper: Make VM run like container
“All problems in computer science can be
solved by another level of indirection, except of
course for the problem of too many
indirections.”
–David Wheeler
Agenda
• Background
• Hyper: Make VM Like Container
• Hyper Internals
• Next Step: Hypernetes — Real CaaS w/o IaaS
Background
• Docker is the most disruptive innovation in Cloud
• Docker is based on Container technology
• Container is light weight comparing to VM
• But container is weak isolated until now ——
• How to make container strong isolated like VM
What is Docker, Fundamentally?
• Docker = Linux Container + Docker Image
• Container —
• Runtime Isolation (light and weak)
• Image —
• All in One: app and its dependencies (ref rpm/deb)
• Immutable: one step convergence (ref chef/puppet)
• Layered: storage and distributing friendly (ref vm image
What is Docker: the Answer
DOCKER is APP-CENTRIC, and
APP-CENTRIC is AWSOME
Container vs. VM

Container Virtual Machine
• The critique of virtual machine is about
"machine" rather than "virtual"
• Why not make an App-Centric VM
What is Hyper, Fundamentally?
Hyper ≈ hypervisor + docker image
Hyper: Look & Feel

launch
How Hyper Works
• Then it works Hyper VM Hyper
