Google Cloud Storage

Google Cloud Storage is a RESTful online file storage web service for storing and accessing data on Google Cloud Platform infrastructure. The service combines the performance and scalability of Google's cloud with advanced security and sharing capabilities. It is an "Infrastructure as a Service" (IaaS), comparable to Amazon S3 online storage service. Contrary to Google Drive and according to different service specifications, Google Cloud Storage appears to be more suitable for enterprises.
Feasibility.
User activation is resourced through the API Developer Console. Google Account holders must first access the service by logging in and then agreeing to the Terms of Service, followed by enabling a billing structure.
Design.
Google Cloud Storage stores objects (originally limited to 100 GiB, currently up to 5 TiB) in projects which are organized into buckets. All requests are authorized using Identity and Access Management policies or access control lists associated with a user or service account. Bucket names and keys are chosen so that objects are addressable using HTTP URLs:
Features.
Google Cloud Storage offers four storage classes, identical in throughput, latency and durability. The four classes, Multi-Regional Storage, Regional Storage, Nearline Storage, and Coldline Storage, differ in their pricing, minimum storage durations, and availability.
