Google I/O 2011: Scaling App Engine Applications

Justin Haugh, Guido van Rossum

During this talk, we'll discuss how to write highly scalable apps on App Engine. We'll describe how an app is granted more instances as traffic grows, and the importance of low latency, low memory usage, concurrency, async APIs, load testing, and profiling. We'll also help you avoid common pitfalls, like entity contention and hot tablets.

@YoLninYo Thankfully Guido is a man of quality character, and doesn't agree with your ... need to worship people. He's happy to work with junior engineers rather than sociopathically have them lick his boots.

Great video Thanks for sharing this discussion.

can't you use Prediction API's for prediction ? :)

@lessercylinder I get what you're saying but my point is not about ego, it is more about giving proper respect to people of Guido's calibre. Why can't he be given a separate talk? Google IO is half techno babble, would it be too difficult to give people like Guido etc. a platform of their own, and let them speak their minds?

Yeah they work for the same company, but one guy is an empoloyee & the other guy's stuff the whole company is built around. There is a difference. Google better recognize!

@YoLninYo your idea of software engineering is an incredibly toxic. The point is that we ARE all the same. There is no one who is better than another person. When your entire career is dedicated to working with other people to collaborate and build things, egos like yours have no place.

@ 4:55, "if it's a laptop, you're " what does he say?

I can't hear it properly.

Why not subtitles/transcripts to this like there's for movies?

It would just help to have one, not a big deal right.

[YoLninYo]

why do they put a legend like Guido with a wet behind the ear "software engineer" ? Is this some google way of showing how "egalitarian" they are? Somehow this made me feel offended.

They put the creator of python with some swift talker who is a total nobody! no offence meant to the nobodies, but people like Guido, Rob Pike et. al. are legends of computer science, they deserve a little more respect from us. Just because they work for the same company, they're not all of a sudden "equal".

Guido, you are an impressive speaker.
