The First Generation Cloud Dealt with Orchestration; The Next Generation Will Deal with Applications

During the past decade, the world of the cloud has been consumed with orchestration: How can we make an infrastructure which can adapt to the needs of the enterprise?  Words like automation, flexibility, and control have ruled the world of the cloud to date.

But now that a number of cloud orchestration projects have begun to mature, it's time to take a look at the applications themselves.  Until now, the applications which dwell in clouds look suspiciously like the applications which inhabited the traditional datacenter.  And while they may function pretty well, they are not really designed with an agile infrastructure in mind.

Make It Small, Make It Fast

In the world of the cloud, it would make sense to have small applications which are lightweight and nimble.  They should be quick to start and stop.  They should do what they need to do and then get out of the way so that valuable compute resources can be focused on applications which require compute power -- like databases, for instance.

Docker has made inroads in this area by using container technology to share the operating system space between many applications.  Virtual machines contain a full operating system for each instance, which requires lots of disk space, lots of memory, and prolonged startup and shutdown times.  Docker-type solutions keep memory usage down, make startups and shutdowns lightning quick, and create application bundles which are easy to deploy.

But shared resources can mean that an exploit of the base operating system can cause the compromise of dozens or even hundreds of applications resident on that host.  It also means that multi-tenant situations are difficult to achieve, as shared resources could mean increased ability to see your neighbor's work. If you don't trust your neighbor, you want a wall between the two applications which makes them invisible to each other, just like the solutions already extant in the world of hypervisors.

Recently, I attended a conference session where the presenter said of his mature project, "We are focused mostly on performance these days, not much on new stuff."  To most people, I'm sure this statement was unremarkable.  However, as one who is associated with a project which is over a decade old and powers many of the largest clouds in the world, I found the statement both sobering and horrifying.

It is sobering to think that lack of  innovation within a project speaks of the impending end of the effort; a race has been run, a finish line crossed, and a horse put out to pasture.  It's the inevitable death of all things when there is no more room for real ingenuity or growth.  All that remains is to wait for the inevitable replacement to stand up and become the new go-to solution in the area.

But it is also horrifying to think that a project would choose to so casually embrace this fate.  I understand that once you set out to do something and you succeed, it is easy to say, "Well, I guess we're done with the new and interesting stuff."  But if you come to that conclusion too quickly, you probably suffer from a gigantic vision problem.

Couldn't make it to this year's Xen Project User Summit in New York City?  No problem!  Most of the videos are now available for viewing at XenProject.org.  These aren't highlight reels or a handful of talks from a few selected people; these are the meat-and-potatos talks from our event.  Most sessions are available right now; the final few should be posted in the next few days.

Take a look at some of the great talks already available...
