    iii

    iii

    Effortlessly compose, extend, and observe every service

    iii is a backend unification engine that organizes application behavior around a small set of primitives such as functions, triggers, and workers. It is designed to connect existing backend systems into a more inspectable and programmable runtime. The project includes a console for developers and operators to inspect functions, triggers, traces, and live state. Its goal is to reduce backend sprawl by giving teams a single operational layer for event-driven and function-based workflows. iii appears especially useful for teams that want clearer visibility into distributed backend behavior without replacing every existing component. Its main value is combining orchestration, observability, and operational control into a compact backend engine.

    CloudRetro

    CloudRetro

    Web-based Cloud Gaming service for Retro Game

    CloudRetro provides an open-source cloud gaming platform for retro games. It started as an experiment for testing cloud gaming performance with WebRTC and Libretro, and now it aims to deliver the most modern and convenient gaming experience through technology. Theoretically, in cloud gaming, games are run on remote servers and media are streamed to the player optimally to ensure the most comfortable user interaction. It opens the ability to play any retro games on a web-browser directly, which are fully compatible with multi-platform like Desktop, Android, IOS. In ideal network condition and less resource contention on servers, the game will run smoothly as in the video demo. Because I only hosted the platform on limited servers in US East, US West, Eu, Singapore, you may experience some latency issues + connection problem. You can try hosting the service following the instruction the next section to have a better sense of performance.

It is designed to work directly with net/http. It is also BYOR (Bring Your Own Router), and plays well with most http routers available in the Go community by fully supporting net/http. Negroni is currently translated in a number of different languages, and comes with some default middleware that can be used for most applications and makes getting started with some of Negroni’s features a lot easier.

    Puma

    Puma

    A Ruby/Rack web server built for concurrency

    Unlike other Ruby Webservers, Puma was built for speed and parallelism. Puma is a small library that provides a very fast and concurrent HTTP 1.1 server for Ruby web applications. It is designed for running Rack apps only. What makes Puma so fast is the careful use of a Ragel extension to provide fast, accurate HTTP 1.1 protocol parsing. This makes the server scream without too many portability issues. If you are using Bundler, just add Puma to your project's Gemfile. Once you've installed your bundle, start Puma. If you are not using Bundler, you can install Puma directly from the command line. On MRI, there is a Global VM Lock (GVL) that ensures only one thread can run Ruby code at a time. But if you're doing a lot of blocking IO (such as HTTP calls to external APIs like Twitter), Puma still improves MRI's throughput by allowing IO waiting to be done in parallel.

    Suave

    Suave is a simple web development F# library

    Suave is a simple web development F# library providing a lightweight web server and a set of combinators to manipulate route flow and task composition. Suave is inspired in the simplicity of Happstack and born out of the necessity of embedding web server capabilities in my own applications. Suave supports Websocket, HTTPS, multiple TCP/IP bindings, Basic Access Authentication, Keep-Alive. Suave also takes advantage of F# asynchronous workflows to perform non-blocking IO. In fact, Suave is written in a completely non-blocking fashion throughout. We have a NuGet ready for your testing needs; Suave is an excellent server for running in-process integration tests, as it's very fast to spawn. On an ordinary laptop, running hundreds of randomized tests and micro-benchmarks as well as all Suave unit tests, take about 5 seconds on mono.
