Closed 10 months ago . Recently Amazon launched Lightsail. Is there any difference between them? If yes, then what's the difference? Are Lightsail instances more powerful than EC2? 回答1: Testing¹ reveals that Lightsail instances in fact are EC2 instances, from the t2 class of burstable instances. EC2,

问题 I'm writing a simple logging service in DynamoDB. I have a logs table that is keyed by a user_id hash and a timestamp (Unix epoch int) range. When a user of the service terminates their account, I need to delete all items in the table, regardless of the range value. What is the recommended way of doing this sort of operation (Keeping in mind there could be millions of items to delete)? My options, as far as I can see are: A: Perform a Scan operation, calling delete on each returned item,

问题 I am trying to automate the GoogleAuth process when using the pydrive library (https://pypi.python.org/pypi/PyDrive). I've set up the pydrive and the google API such that my secret_client.json works but it requires web authentication for gdrive access every time i run my script: from pydrive.auth import GoogleAuth from pydrive.drive import GoogleDrive gauth = GoogleAuth() gauth.LocalWebserverAuth() drive = GoogleDrive(gauth) textfile = drive.CreateFile() textfile.SetContentFile('eng.txt')

问题 I want to reuse some code logic from a self-hosted web application in my Windows Azure web application. Currently I have code like this: void myFunction( params ) { //environment-neutral code } I need to rewrite that code to make the program act differently depending on whether is is on Azure: void myFunctionModified( params ) { if( onAzure() ) { //run Azure-specific code } else { //run non-Azure code } } yes, I know about virtual functions, but I'll need such code for at least instantiating

问题 I am learning Paxos algorithm (http://research.microsoft.com/en-us/um/people/lamport/pubs/paxos-simple.pdf) and there is one point I do not understand. We know that events follow a timely order, and it happens when, say, events 1-5 and 10 are decided, but 6-9 and 11 thereafter are not yet. In the paper above, it says we simply fill in the gap between 6-9 with no-op values, and simply record new events from 11 and on. So in this case, since event 10 is already recorded, we know some kinds of

问题 I've deployed an Azure service - once in a while I see in my logs that OnStop() is called, then after about 20 minutes OnStart() is called. I'd like to know why that's happening. How can I know whether my role is restarted manually or by Azure runtime? 回答1: Can you explain what you mean by restarted manually? Is that someone logging in via RDP and hitting reboot? You only have a few options that can trigger a reboot: Someone logged in via RDP and literally rebooted. No way to track that one.

问题 I would like to boot from an EBS snapshot for convenience but then I would like to detach the volume after launch so I don't have to pay for it. Is this possible? 回答1: No, it's not possible. The EBS volume is the system partition so it the same as pulling the harddrive out of the server. To reduce costs you could try to minimize the size of the volume so it has just enough space to hold all the system files and your data. 来源： https://stackoverflow.com/questions/2453852/ec2-booting-from-an-ebs

问题 CI have written an R package for OpenCPU and want to use it on my own Cloud server. I cannot access any functions even though the package itself is recognized and can be updated, and I can access other (non-custom, e.g. base or stats) packages normally via POST and GET. I have installed the custom package together with all dependencies to /usr/local/lib/R/site-library and I can use the functions from within an R session locally on the server. > TestConnectivity function (x = 100) { return(sum
