Dan (he’s a good guy, check him out on Twitter @dturkenk), your “East Coast vs West Coast PaaS Psychology. And Why It Matters.” is great write up. Loved it! I’ve got to say, I’m pretty much in agreement with almost every single thing you’ve written here. Matter of fact I’m staunchly in agreement with a lot of it. There’s a few other abstractions I’d like to add, that makes the reality of east coast and west coast PaaS what it is, and why some of these things are like this.
You write,
“While the West Coast conception of PaaS is an appealing vision, (and may well be the answer for many smaller companies and start ups)…”
which I agree with whole heartedly. The fast, agile, and lean companies of tomorrow need this type of technology today. They can’t survive trying to throw together traditional environments. They need PaaS like people need food and water. However you also write on the end of that statement,
“it doesn’t really mesh with today’s enterprise reality.”
which I know is true, sometimes. There are however many enterprises out there that do indeed want to and are starting to move over completely. These enterprises see the value add and are not waiting around. They’re not going halfway with a hybrid solution, they’re moving full bore and realizing economies of scale that internal IT shops will not and cannot realize.
This type of enterprise, is where a lot of the west coast and east coast mentality is realized. There is a risk aversion on the east coast, rightfully so with such things as financial institutions and Government being a dominent presence on the east coast. On the west coast though, the enterprises operate under a very different cultural perspective, they attempt to realize the advantages – competitive and disruptive that they are – of startups and small business. It’s as much a competitive survival for the west coast enterprise as it is for the startups and small business. Thus, we get some of the differentiators not just in technology, but in the enterprises themselves. This is the core of this psychological difference, not something that was born from a PaaS psychology, but for the ore business itself. Being that PaaS technology and its origins are from the west coast, it becomes obvious why most are focused on public or privately accessible public infrastructure.
Overall, the culture expands into all those sectors in the east and west, and starts to stand out when we look at different approaches to doing business and competing. Regardless of these minor differences and the associated differences in doing business, we both agree on one thing regardless of which coast we’re on.
The applications and application developers is where the value is for enterprises, mid-size, and small businesses, and startups.
Without doubt, PaaS technology is focused on that core value. Enabling developers to build applications in an easier, faster, scalable and more reliable way. So far, all the platforms are doing a damn good job helping us developers do just that.

It does sound like you’re in agreement with a lot of what Dan wrote; we all agree enterprise will and must adopt PaaS. I don’t think that east coast vs. west coast PaaS is a distinguishing factor and attribute we apply to enterprises – but rather label more applicable to us vendors. Enterprises, regardless of where they are, are all bound by one thing: their size and complexity. East coast or west coast, they are not adopting PaaS in a way that says “You know what, chuck everything we’ve done for 20 years out the window and let’s start fresh. Adn we’re using node, and ruby, and nothing else going forward. Oh, and our developers can forget about regulations and performance and legacy.” That is a completely unrealistic view of the world. Period. East coast vs. west coast is merely an acknowledgment that some of us vendors grew up with DNA that focused on startup problems (West Coast) and others on enterprise problems (East Coast).
Oh, and the comment that “Being that PaaS technology and its origins are from the west coast, it becomes obvious why most are focused on public or privately accessible public infrastructure.” is probably misplaced. The oldest and most proven (i.e. running the most important apps) PaaS technologies I’ve seen running in the wild were built YEARS ago by enterprises in NYC and in Europe;-)
I’m speaking from a “brought PaaS to market…”. Besides Apprenda I don’t know of another company that has brought an actual PaaS offering, deployed, to market. Red Hat might count, but they weren’t exactly first.
But anyway, yeah, not really any disagreement. We can talk who is or isn’t innovating sometime for sure. That I’m sure will be a battle.
I think I generally agree with that picture and the sentiment. :p
