The blogosphere has plenty to say about cloud computing, but most content targets the business, CIO, or IT crowds. Information exists for developers who want to produce software friendly to cloud computing, but it’s more scattered, it’s vendor-centric, and it doesn’t match the SEO profile that obsesses much of the industry. As a result, I believe that many developers have only hazy ideas about how they can leverage the power of the cloud to provide radical improvements in scale, responsiveness, and connectivity for their customers.
This ought to change. Cloud computing isn’t just interesting to datacenter managers; it enables many new technological strategies. Cloud-savvy engineering can boldly go where no software has gone before—if we’re smart enough to take it there.
On my company’s website, I’ve begun a new series of blog posts about how to “cloudify” your code and designs. Read the inaugural post, and check back on Fridays for new installments in the series. I’ll be making connections back to concepts here on codecraft, such as what the programming language of the future ought to look like, how to encapsulate for cloud, and so forth.
I believe that a competence with cloud–cloud-oriented programming, if you will–will be a checkbox on future tech resumes.
If X works for 1 ___ [minute | user | computer | customer | …], then 100X ought to work for 100, right? And 1000X for 1000?
Sorry, Charlie. No dice.
One of my favorite books, Universal Principles of Design, includes a fascinating discussion of our tendency to succumb to scaling fallacies. The book makes its case using the strength of ants and winged flight as examples.
Have you ever heard that an ant can lift many times its own weight–and that if that if one were the size of a human, it could hoist a car over its head with ease? The first part of that assertion is true, but the conclusion folks draw is completely bogus. Exoskeletons cease to be a viable structure on which to anchor muscle and tissue at sizes much smaller than your average grown-up; the strength-to-weight ratio just isn’t good enough. Chitin is only about as tough as fingernails.

I’d long understood the flaws in the big-ant-lifting-cars idea, but the flight example from the book was virgin territory for me.
Humans are familiar with birds and insects that fly. We know they have wings that beat the air. We naively assume that at much larger and much smaller scales, the same principles apply. But it turns out Continue reading →
