Dear Sir/Madam,
We would like to introduce to you that we are a team with two AWS sysop administrators .
We are not for sure where do you store the upload and download data on amazon but we will try to give you some suggestions for solution as below :
1) if you store your data on S3 we can use aws-cli to download & upload or use aws api for some programming languages , such as : Php, Python, Java to download and upload .
2) if you store your data on ec2 we can use bash (scp, sftp etc) to download and upload the data.
We don't know your specific requirement about speed, schedule to download, upload, the file size, your strategy when storage reach limitation etc.
Therefore please give us a chance to discuss with you. We will help you solve your problem.
And please don't hesitate to contact with us to discuss for more detail about this project.
My Skype is phuongluuho.
Warms regards,
Phuong.
