Re: [Openstack] Refocusing the Lunr Project

2011-07-08 Thread Erik Carlin
From a Rackspace perspective, we do not want to expose block operations in the compute API. The plan has been to expose the attach/detach as nova API extensions, and that still makes sense, but will there be a separate, independent block service and API? Erik From: Chuck Thier

Re: [Openstack] Thinking about Openstack Volume API

2011-04-22 Thread Erik Carlin
To promote consistency across OpenStack APIs, I suggest we follow the same model as in OS compute. That is, have a high level entity called /flavors. One can query flavors to determine what types of volumes are available (based on sla, performance tiers, whatever) then pass in the flavor ID

Rick - Agree with everything below. IMO, #3 should apply in general to all OS services (core network, block storage, load balancing, etc.) We want things to work as a suite of services but each service should be independent and deployable by itself. There will obviously by interface

Good discussion. I need to understand a bit more about how cross org boundary bursting is envisioned to work before assessing the implications on server id format. Say a user hits the http://servers.myos.com api on zone A, which then calls out to http://servers.osprovider.com api in zone B,

John - Are we just talking about compute aspects? IMO, we should NOT be exposing block functionality in the OS compute API. In Diablo, we will break out block into a separate service with it's own OS block API. That means for now, there may be functionality in nova that isn't exposed (an

That all sounds good. My only question is around images. Is glance ready to be an independent service (and thus have a separate API) in Cactus? Erik From: John Purrier j...@openstack.orgmailto:j...@openstack.org Date: Mon, 28 Feb 2011 16:53:53 -0600 To: Erik Carlin erik.car

Re: [Openstack] OpenStack Compute API 1.1

2011-02-18 Thread Erik Carlin
The way I see it, there isn't a singular OpenStack API (even today there is swift, nova, and glance). OpenStack is a suite of IaaS each with their own API – so there is a SUITE of standard OS APIs. And each OS service should strive to define the canonical API for automating that particular

I would just call it VMDK. That's what Vmware (http://www.vmware.com/technical-resources/interfaces/vmdk.html) and everyone else calls it, even though there may be extra files to support it. We're just naming the disk format here. We had also talked about the IMG disk format to support AMIs but

Correct me if I am wrong, but I believe AMIs use IMG so that should be another disk format a well (it would be the only one in the AMI appliance format unless AWS changes it). Is there enough variance in the virtual disk and envelope formats over time that we want to include version columns or

We know Amazon is highly, highly elastic. While the instances launched per day is impressive, we know that many of those instances have a short life. I see Guy is now teaming up with CloudKick on this report. The EC2 instance ID enables precise measurement of instances launched, and CloudKick
