cloud

问题 I am managing a web application that uses Rackspace Cloud Hosting to store user images and files. Currently, when serving user pages, the real links to the files in the cloud are used. Potentially a user could view other users' files by guessing the file names. The file names are obfuscated containing about 30 alphanumeric digits, bit still this does not feel good. Is my concern valid, and if it is how can I best solve this? 回答1: I think it depends on the sensitivity of the information in the

问题 I have google cloud compute engine which is centOS 7. It was located in asia-southeast1 (SG). However, I checked the external IP it was on the Mountain View, CA. Is it possible to change the IP where it can be located to Singapore? Thanks, Edmhar 回答1: Sure.

问题 Suppose my Azure role is notified that it will be terminated soon and technically can clean up local resources after itself (temporary files for example). Should it do so? I'm not asking about whether someone will see my leftover temporary files - just how my role can be a polite good Azure citizen. Does it make sense for the role to clean up local resources or should it just leave everything as is? 回答1: Like Stuart said, there's no reason to do any local storage cleanup. You either leave it

问题 Is it possible to trigger a resize of an Azure VM automatically based on a set condition? For example, increase from a 'Medium' machine to 'Large' if the processor/RAM is over 90% usage out for 5 minutes? Then, obviously scale back down when usage reduces? Or... is it possible to schedule a resize between (peak) UK office hours then downscale off-peak? Just a thought... 回答1: Worth checking out the Auto Scaling Building Block from the patterns and practices team, part of the Enterprise Library
