Yeah, AppEngine has been around for a while. That doesn't make my general AppEngine article less timely. Hey, I don't just write about stuff because its hip. In a few months, I'll announce what Google Chrome means for the web landscape. Seriously.
Although a lot of people believe Google App Engine is a very big thing and extremely important to the landscape of the web, I get the strong impression from outside the camp that its more of a toy, and I want to address that. As with my quick review of App Engine itself, its hard to make real calls when everything is still beta, but we're working with what we've got here. The people who see the real potential of App Engine feel it and the people who just think its neat Just Don't Get It. What is there to get that so many developers are missing and why would those of us that do think its important enough to be evangelical about, as I'm doing right now?
Once again, making any claims or arguments in this discussion has to start by defining what we're talking about in the first place. Are we talking about the choice of first runtime (Python) and included libraries (namely, the Django templates)? Is Google's design of the Datastore API and what other service APIs they provide the import factor to praise or ignore? Perhaps the details of their hosting plan makes it all worth gold, regardless of what software they put on top of all that iron? Going with my previous post on App Engine, it all comes down to the experience we need to discuss.
For Newbies This Means...
People just starting out with Python, web development, or even programming at all have a great opportunity here. They can focus on writing code in a very low-barrier environment and not worry about a lot of the details of deployment and hosting that got in the way before. The river between the Field of Writing Code and the Field of Running Your Website has been reduced to a trickle that can easily be waded across.
Few deny the benefit of the lower barrier here for the uninitiated, but there may be some misplaced valuation. There is more to benefit these individuals than staving off their eventual need to understand how to manage and deploy to their own hosting solution. New developers are in an amazing position that none of the rest of us are privy to: they may go entire careers without knowing how to setup a webserver. This is wonderful. Does it mean they are incapable of it or that we'll get a flood of developers who are less able to perform? I believe we see a change in the way we learn. We're narrowing disciplines and we aren't wasting mental cycles and man hours having every gear understand the entire machine. If you write code well, then learn that and just that. Ignore the rest.
Every coder today knows something about designing, even if they aren't good at it. Anyone who has written a line of code, HTML, or CSS for the web has probably configured a database at some point. We take this as normal and expected, and just rites of passage. We fit ourselves into specialties as we gain experience in our niche, but we all have an expectation of knowing a little about a lot. We seem adverse to the idea that the next generate will know how to do their job well, and not at all the jobs we know, but don't do on a regular basis.
For Experienced Hobbyists This Means...
Even when a developer reaches the point that hosting things themselves, managing servers, and configuring databases is feasible, none of it is necessarily worth the effort. All of that is time that could be spent solving the real problem at hand, with your family, or on your real job. The ability to do something doesn't negate the cost in time and effort of doing it. Being able to handle a problem when it arises does not make it meaningless to avoid the possibility of that adversity in the first place.
For Serious Ventures This Means...
With the flood of tiny little apps being launched on App Engine, the question of a large scale app being unrolled on the platform is a big one. Will anyone really build businesses hosted on App Engine? Can Google be trusted with your code? Will this platform offer the real power and opportunity needed to meet the demands of a growing business? None of these are particularly interesting to me in this context, because the deeper question is if the benefits that work for tinkerers and hobbyists extends to "serious" work. I think it does.
