gRPC releases Beta opening door for use in production environments

Posted by Mugur Marculescu, Product Manager

The gRPC team is excited to announce the immediate availability of gRPC Beta. This release marks an important point in API stability and going forward most API changes are expected to be additive in nature. This milestone opens the door for gRPC use in production environments.

We’re also taking a big step forward in improving the installation process. Over the past few weeks, we’ve rolled out gRPC packages to Debian Stable/Backports. Installation in most cases is now a two line install using the Debian package and available language specific package managers (e.g. maven, pip, gem, composer, pecl, npm, nuget, pod). In addition gRPC docker images are now available on Docker Hub.

We’ve updated the documentation on grpc.io to reflect the latest changes and released additional language-specific reference docs. See what’s changed with the Beta release in the release notes on Github for Java, Go and all other languages.

In the coming months, the focus of the gRPC project will be to keep improving performance and stability and adding carefully chosen features for production use cases. This is part of our principles and goals to enable highly performant and scalable APIs and microservices on top of HTTP/2. Documentation will also be clarified and will continue to improve with new examples and guides.

We’ve been very excited to see the community response to gRPC and the various projects starting to use it (etcd v3 experimental api, grpc-gateway for RESTful APIs and others). We really want to thank everyone who contributed code, gave presentations, adopted the technology and engaged in the community. With your help support we look forward to the 1.0!

Introducing gRPC a new open source HTTP 2 RPC Framework

Today, we are open sourcing gRPC, a brand new framework for handling remote procedure calls. It’s BSD licensed, based on the recently finalized HTTP/2 standard, and enables easy creation of highly performant, scalable APIs and microservices in many popular programming languages and platforms. Internally at Google, we are starting to use gRPC to expose most of our public services through gRPC endpoints as part of our long term commitment to HTTP/2.

Over the years, Google has developed underlying systems and technologies to support the largest ecosystem of micro-services in the world; our servers make tens of billions of calls per second within our global datacenters. At this scale, nanoseconds matter. Efficiency, scalability and reliability are at the core of building Google’s APIs.

gRPC is based on many years of experience in building distributed systems. With the new framework, we want to bring to the developer community a modern, bandwidth and CPU efficient, low latency way to create massively distributed systems that span data centers, as well as power mobile apps, real-time communications, IoT devices and APIs.

Building on HTTP/2 standards brings many capabilities such as bidirectional streaming, flow control, header compression, multiplexing requests over a single TCP connection and more. These features save battery life and data usage on mobile while speeding up services and web applications running in the cloud.

Developers can write more responsive real-time applications, which scale more easily and make the web more efficient. Read more about the features and benefits in the FAQ.

Alongside gRPC, we are releasing a new version of Protocol Buffers, a high performance, open source binary serialization protocol that allows easy definition of services and automatic generation of client libraries. Proto 3 adds new features, is easier to use compared to previous versions, adds support for more languages and provides canonical mapping of Proto to JSON.

The project has support for C, C++, Java, Go, Node.js, Python, and Ruby. Libraries for Objective-C, PHP and C# are in development. To start contributing, please fork the Github repositories and start submitting pull requests. Also, be sure to check out the documentation, join us on the mailing list, visit the IRC #grpc channel on Freenode and tag StackOverflow questions with the “grpc” tag.

Google has been working closely with Square and other organizations on the gRPC project. We’re all excited for the potential of this technology to improve the web and look forward to further developing the project in the open with the help, direction and contributions of the community.
