Nitro License Docs Twitter Discussions

Nitro (formerly known as Go Micro) is a blazingly fast framework for distributed app development.

Overview

Nitro will provide the core requirements for distributed app development, IoT, edge and p2p including RPC and Event driven communication. The Nitro model is in-memory defaults with a pluggable architecture. Blaze with pure in-memory development and swap out as needed to go multi-process or multi-host.

Nitro is currently undergoing a complete rewrite and is considered unstable for use.

Features

Nitro is now focusing on dapps, IoT, edge and p2p. Features include:

  • Lightweight RPC based communication
  • Event broadcasting and notifications
  • CRDT Data synchronisation and storage
  • Consensus protocol and execution engine
  • WebAssembly target compilation support
  • Unique randomized token generation aka BLS
  • P2P networking stack written in user space

FAQ

What happened to Go Micro?

Go Micro has now been renamed to Nitro. Go Micro moved back to being a personal project. So no longer lives under the organisation github.com/micro. The company is now doubling down on Micro itself and has pulled in the needed interfaces to consolidate a Server, Framework and CLI into one tool. Go Micro is now no longer maintained by a company. Yet it continued to create confusion even as a personal repo. So for that reason, we're renaming to Nitro.

Why has the license changed from Apache 2.0 to Polyform Noncommercial

Go Micro was largely a solo maintained effort for the entirety of its lifetime. It has enabled the creation of a company called Micro Services, Inc. which now focuses on Micro as a Service and has consolidated any interfaces here into a service library in that project. For the most part, Go Micro was unfunded and in some ways under appreciated. In version 3.0, going back to something of a personal project of more than 6 years I have made the hard decision to relicense as a noncommercial project. For any commercial applications I am looking for github sponsorship so that I can then use those funds for maintenance and support efforts.

Where are all the plugins?

The plugins now live in github.com/asim/nitro-plugins. This was to reduce the overall size and scope of Go Micro to purely a set of interfaces and standard library implementations. Go Plugins is Apache 2.0 licensed but relies on Nitro interfaces and so again can only be used in noncommercial setting without a commercial license.

What's the new direction of Nitro?

Nitro will now focus on distributed app development using the Go standard library. It will continue to define abstractions for distributed systems but will only do so without external dependencies. All those external dependencies will live in Nitro Plugins. In this manner the hope is Nitro can be picked up with minimal overhead for all sorts of new applications that have a low memory or low resource footprint. The assumption is there are places which would like to use distributed apps just as embedded systems or web assembly, unikernels, and related targets that would benefit from a framework that defined these as primitives for such use.

Where is the top level Service definition?

The top level service definition has been moved to the app package. Nitro exploded in terms of the interfaces it offered. While originally it was a small library, this increase in packages has meant the top level can't really provide full scope for everything. It's unclear at this time whether the top level definition should return.

Where are the default initialised interfaces?

The defaults are gone. This proved to be a bad design pattern which meant one definition of an interface needed to live along side it. Over time it became quite complex and switching out meant you had a pre-initialised implementation there with a lot of cleanup that wasn't possible. So removing it feels as though a cleaner approach to interface design and modularisation of packages.

Where is the cmd package, flag parsing etc?

These are also gone. The complexity of this code was quite honestly horrible. The command package had to make assumptions about how to load plugins because every package depends on other package. As a whole system this became impossible to maintain and even in Micro we'll be looking to scrap it for simpler initialisation. The flag parsing, plugin loading, etc is all gone in favour of users self defining it. What we find is most plugins require more initialisiation than what we can provide as hard coded values. For this reason we may look into github.com/google/wire as a better alternative.

How do Nitro and Micro now differ?

Micro is a platform for cloud native development. A complete experience that includes a server, framework and multi-language clients. Beyond that it also include environments, multi-tenancy and many more features which push it towards being a hosted Micro as a Service offering. It is a complete platform.

Nitro is more of a pluggable framework for distributed app development and now once again a purely personal project maintained by me and perhaps others who still find use for it commercially or noncommercially. It's of sentimental value and something I'd like to carry on for personal projects such as things related to edge, IoT, embedded systems, p2p, web assembly, etc.

I used Go Micro to build microservices. What should I do now?

You should quite honestly go look at Micro and then consider the hosted offering at m3o.com which starts as a purely free Dev environment in the cloud. Micro continues to address many of the concerns and requirements you had if not more. It is likely you managed metrics, tracing, logging and much other boilerplate that needed to be plugged in. Micro will now take this complete platform story approach and help you in that journey e.g you're probably running managed kubernetes on a major cloud provider with many other things. We're doing that for you instead as a company and platform team.

I want to use Go Micro version 2.0 for my company. Can I still do that?

Yes. Go Micro 2.0 is still Apache 2.0 licensed which means you can still freely use it for everything you were using before. If you're a new user you can do the same. These things are using go modules so you're import path is simply github.com/micro/go-micro/v2 as it was before. Because GitHub handles redirects this should not break. Please continue to use it if you like, but my own support for 2.0 is now end of life. I will be focusing on some side hacking on 3.0 as I find time.
