In this industry, everyone seems to talk about innovation, but very few platforms exist which foster innovation.  More times than not, "innovation" is simply a buzzword used by some marketing campaign to hawk something about as novel as twenty-year-old accounting software.

Innovation does occur, of course.  But often real innovation leverages what already exists to create something which doesn't yet exist.  It may borrow from the known, but it produces something previously unknown.  For example, the industry has been going wild over cloud computing in the past few years, but many of the core cloud computing concept are actually old mainframe concepts reimagined in the world of commodity servers.

Making a Place for Innovation to Thrive

A bare-metal hypervisor -- like the one produced by the Xen Project -- can be an excellent platform for innovation.  We think of hypervisors as old technology, plumbing for newer technologies like cloud -- and, indeed, they are.  But the nature of the bare-metal hypervisor makes it an excellent platform for innovation to take place.

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.

Historically, the computer industry has been impressed with big things.  In the early decades, the mainframes and supercomputers were all the rage.  Even as the technology began to shrink, big rollouts supplanted the big machines.  And now you can find powerful technology which easily fits in the palm of your hand -- but you've probably only heard of the brands which sell in huge numbers.

This industry likes big things.  But sometimes the greatest value comes from the smallest things.  That can certainly be said of Open Source conferences.

Good Things Really Do Come in Small Packages

I've spoken at several dozen Open Source conferences over the years.  I remember when LinuxWorld Conference and Expo was all the rage a decade ago.  It had thousands of attendees, gigantic booths, a huge amount of swag, and plenty of press coverage.  With all its lights and noise, that conference was something to behold.

But I don't find myself wishing I could revisit those days. Instead, I find myself enjoying the smaller, community-driven, regional conferences.  These conferences aren't large, aren't noisy, and don't come with mountains of swag to take home, but they provide attendees with something much more valuable: the equipment to succeed.

It varies from conference to conference, but most of these local conferences include two very important elements: excellent information and local networking.
