Package cloud contains a library and tools for open cloud development in Go. The Go Cloud Project allows application developers to seamlessly deploy cloud applications on any combination of cloud providers. It does this by providing stable, idiomatic interfaces for common uses like storage and databases. Think `database/sql` for cloud products. At the core of the project are common types implemented by cloud providers. For example, the blob.Bucket type can be created using gcsblob.OpenBucket, s3blob.OpenBucket, or any other provider. Then, the blob.Bucket can be used throughout your application without worrying about the underlying implementation. This project works well with a code generator called Wire (https://github.com/google/wire/blob/master/README.md). It creates human-readable code that only imports the cloud SDKs for providers you use. This allows Go Cloud to grow to support any number of cloud providers, without increasing compile times or binary sizes, and avoiding any side effects from `init()` functions. For sample applications and a tutorial, see the samples directory (https://github.com/google/go-cloud/tree/master/samples).
