Amazon’s cloud storage services are going to be getting another major competitor this week: Google.

We hear that this week during its I/O conference, Google will be announcing a new service that is a direct competitor with Amazon’s S3 cloud storage. Google’s service will be called Google Storage for Developers, or ‘GS’. We believe it will be available in a private beta initially.

We also hear that the service will be positioned to make it very easy for existing S3 customers to make the switch to Google Storage.Features will include a REST API, the ability to use Google accounts to offer authenticated downloads, and data redundancy. Developers will be able to use a command line tool to manage their data, and there will be a web interface as well.We’d previously reported that Google was looking to expand its cloud service offerings, but that it would primarily be focused on ‘value-added’ services that took advantage of technology Google has been using internally, like its translation tools and video processing.

We’re hearing that such value-added services will not be part of this launch, but it is highly likely that they will be coming in the future. And that’s the key here — competitors will have a hard time matching the array of technologies and infrastructure Google has spent years developing.
