SLIDE 10

New AWS FeaturesCustom kernels

● Run a user-specified kernel using an Amazon-provided AKI that runs PVGRUB

● PVGRUB reads /boot/grub/menu.lst from your AMI

● Must support pv_ops kernel

● If you have launched an instance of Maverick recently, you've already used it.

SLIDE 11

Why is the pv-ops kernel good?

● Much less maintenance for development● No need for huge XEN patchset● Will be maintained more like a kernel flavor● Essentially the plain distro kernel with a few configuration tweaks

● Upgrade your kernel in an instance (EBS)● Kernel updates and testing can be done without waiting for official AKI● Makes it more like the normal distribution● Conforms to user expectation

● PV-on-HVM drivers will not make Maverick● There will not be an official Ubuntu AMI for the Amazon Cluster Compute Cloud● Cluster Compute instances require PV-on-HVM drivers which the Server team feels have significant

outstanding bugs● A PPA kernel will be built for testing purposes

SLIDE 12

Other new EC2 features worth mentioning

● Resource tagging

● Filtering the “describe” commands

● Use your own keypair

● Micro-instances

● IAM: Identity and Access Management (Beta)

● Idempotent instances
