Write once, run on any cloud ☁️
The Go Cloud Project is an initiative that will allow 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.
Imagine writing this to read from blob storage (like Google Cloud Storage or S3):
blobReader, err := bucket.NewReader(context.Background(), "my-blob", nil)
and being able to run that code on any cloud you want, avoiding all the ceremony of cloud-specific authorization, tracing, SDKs and all the other code required to make an application portable across cloud platforms.
The project works well with a code generator called
Wire. 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.
You can learn more about the project from our announcement blog post, or our talk at Next 2018:
go get gocloud.dev
go get github.com/google/wire/cmd/wire
Go Cloud builds at the latest stable release of Go. Previous Go versions may compile but are not supported.
samples/tutorial
shows how to get started with the project by
using blob storage.
samples/guestbook
contains an example guestbook application (just
like it's 1999!) that can be run locally, on Google Cloud Platform or on Amazon
Web Services. The instructions take about 5 minutes to follow if running
locally. If you want to see the guestbook app running on cloud resources, it
will take about 30 minutes to follow, and uses Terraform
to automatically provision the resources needed.
This project is in alpha and is not yet suitable for production.
While in alpha, the API is subject to breaking changes.
Go Cloud provides generic APIs for:
- Unstructured binary (blob) storage
- Variables that change at runtime (configuration)
- Connecting to MySQL databases
- Server startup and diagnostics: request logging, tracing, and health checking
Thank you for your interest in contributing to Go Cloud! ❤️
Everyone is welcome to contribute to Go Cloud, whether it's in the form of code, documentation, bug reports, feature requests, or anything else. We encourage you to experiment with Go Cloud and make contributions to help evolve it to meet your needs!
The GitHub repository at google/go-cloud currently contains Google Cloud Platform and Amazon Web Services implementations as examples to prove everything is working. Unfortunately, we cannot support every cloud provider directly from the project.
If you create a repository that implements the Go Cloud interfaces for other cloud providers, let us know! We would be happy to link to it here and give you a heads-up before making any breaking changes.
See the contributing guide for more details.
You can contact us on the go-cloud mailing list.
