Commercial cloud storage services, such as Amazon S3 and Google Cloud Storage, offer highly available, scalable, and unlimited volume object storage services at affordable prices. To speed up the widespread adoption of these cloud products, these providers have developed a good developer ecosystem for their products through explicit APIs and SDKs. The cloud-based file system is a typical product in these active developer communities and has several open source implementations.
