Hi all, I've used Google App Engine for more than 2.5 years. I suffered a hard time to read the English documents, articles and the SDK source code. I thought I knew it very well, but now I find I was wrong. It was a great platform to build either small or big web services, but I believe it won't be a good choice under the new price for both of them.
I think Google will earn most money from the big apps, so let's talk about it first. For the big ones, they must use multiple instances. Each instance charges $0.04 * 24 * 30 = $28.8/month. It's no doubt that you can buy much powerful VPS with these money, and you are unlikely be charged for any other fees like network transport, database, etc. I know Google saves us time of building these service API and maintaining the platform, but it's not worth charging them for each instance. Then the small ones. I would like to talk about my own blog hosting in GAE. I wrote every line of it's code and spent much time on optimizing it. Under the old price, I can keep it free even if it gains 20x traffic (about 200k PVs) than now. But switching to the new one, I'm already have to pay for it $0.01 ~ $0.02 each day, and at least $9 per month. I'm surprised how would this happen, then I found Google played a trick on the datastore operations. Say I need fetch all of my tags. It's just a simple query, only takes less than 1 CPU second to fetch about 50 entities, I can do it 6.5 * 3600 = 23400 times per day. But under the new price, it's considered as 50 Datastore Reads operations, I can only do it 50k / 50 = 1000 times per day. Without memcache, the free quota will be used up in less than 500 PVs (I also need fetch articles, comments, etc.). Though I have used memcache very aggressively, I have no way to handle 10k PVs within the free quota since the memcache often loses the cached data. I remembered the birthday of GAE, Google said we could build an app to server 5 million PVs per month for free. After 2 major price increasing, Google makes it leave preview, and is making us leave it. I still want to say thanks to GAE, I learned Python, the most wonderful language I have seen, because of you. I wish I was the one who made a wrong decision. ---------- keakon My blog(Chinese): www.keakon.net Blog source code: https://bitbucket.org/keakon/doodle/ -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
