I have a bunch of images in Amazon S3 that I need to physically rotate. I currently do this by downloading the image to my server, rotating it using GD and overwriting it back to S3.
This process takes ~5 secs per image. I was wondering if there is any AWS API or such that can do this rotation directly in S3, preferably as in a batch mode?
I would appreciate it if anyone who has any experience with that kind of stuff can give me any pointers!
There is no way to rotate an image 'on' S3. Any method you employ is going to have to read the file from S3, do the rotation, and write it back to S3.
If the server you are doing it on now is not an EC2 instance, than its worth a try to do it there - the latency will be reduced quite a bit. Lambda is another option for you in that it will run within the AWS infrastructure, so network overhead will be reduced.
