Isn't your ability to "migrate workloads without rebooting" similar to Google Compute Engine transparent maintenance and to the live-update capability that Amazon is progressively deploying (which is explained in the post)?
How is it different from Xen or KVM live migration?
- josh2600 12y agoIt's much faster and doesn't use VMs.
- ngrilly 12y agoI guess it's much faster because you migrate containers instead of full VMs? (and also because your implementation is probably very good!)
- josh2600 12y agoIt's faster because we made it fast. What's the difference between migrating a container with network, RAM, CPU and disk state and migrating a VM? IMHO, the difference is that the VM has a massive performance penalty and the container implementation does not. It's not enough to just migrate the container, you also need to migrate the network and the storage too. That's actually the harder part, IMHO. Everyone forgets about network and storage until it's time to go into production and then it gets hard.
