问题 I have a 1M rows of CSV data. select 10 rows, Will I be billed for 10 rows. What is data returned and data scanned means in S3 Select?

问题 I am using signed authorized S3 uploads so that users can upload files directly from their browser to S3 bypassing my server. This presently works, but the file name is the same as on the user's machine. I'd like to save it on S3 as a different name. The formdata I post to amazon looks like this: var formData = new FormData(); formData.append('key', targetPath); // e.g. /path/inside/bucket/myFile.mov formData.append('AWSAccessKeyId', s3Auth.AWSAccessKeyId); // aws public key formData.append(

问题 I need to set nested stack name explicitly in a CloudFormation template, but don't see such option in AWS documentation. Is there way to achieve this? I can specify stack name, when running a parent stack, but all nested stacks, got a randomly generated stack name, based on a resource name created, like: VPC: Type: AWS::CloudFormation::Stack Properties: TemplateURL: https://s3-eu-west-1.amazonaws.com/cf-templates-wtmg/vpc.yaml Parameters: EnvironmentName: !Ref AWS::StackName Which will

问题 I'm having some trouble accessing the AWS credentials in the SDK Store, but it seems to only be a problem when running under IIS. If I hit the same code by invoking an NUnit test with ReSharper the dependency injection works and the S3 client is able to authenticate. IAmazonS3 s3Client = new AmazonS3Client(); Has anyone else run into this problem? How were you able to get the dependency injection to work? [Edit] The credential file approach has been recommended for use with IIS because the

问题 I created a Cloudfront distribution with a CNAME images.domain.com with SSL, and I have 2 S3 buckets: one for user uploads, one for product pictures The default bucket is the uploads bucket I would like to use the same CloudFront for both buckets So I added the 2 buckets as origins and created a "Behavior", with the path /products/* using my product bucket as origin My "Behaviors" are : /products/* to: products bucket (precedence = 0) Default (*) to: uploads bucket (precedence = 1) When I go
