问题 Cloud computing is about providing computing, storage and networking capacities on demand. It is a fresh but very compelling concept for solving some specific tasks, for example: Running CPU heavy computations Having a scalable storage system for raw data Scaling realtime services up to the customer demand as it goes up and down.

问题 Suppose I have an Azure role with three instances running. I ask Azure to change the role count to two either by Management Portal or via Management API.

To specify a Range request in boto, just add a header dictionary specifying the 'Range' key for the bytes you are interested in. Adapted from Mitchell Garnaat's response: import boto s3 = boto.connect_s3()

问题 I have a site that users upload images to. Those images are resized to various dimensions. I currently do that on my server, but was thinking of processing that on AWS or something similar. Is that a good idea? 回答1: I've been using EC2 and dedicated servers for similar tasks, and here are some tips: Use as little IO as possible. If you intend on using things like ImageMagick, know that writing to disk is a waste of io resources (unless you want to cache it anyway.) PHP/GD lets you send jpeg
