Currently working on a project I'm uploading a series of JSON files to Amazon S3 to be received by mobile clients.
In order to reduce costs of individual file transfers, I'm wondering if it's possible to unzip a file once it's on the S3 server as opposed to unzip a file once it's on the EC2 server than transfer it across.
Any help would be appreciated.
S3 doesn't directly support functionality you ask for. However, there are two things you should consider to reduce your costs and transfers:
Compress your JSON files before uploading, store and serve them compressed and let the browser decompress them transparently (some info here)
Additionally you can use the Reduced Redundancy Option for storing your files (you save 50% here, but just on storage, not on transfers)
