Unified Communication X
Communication framework for data-centric high-performance applications
Accelerate Your Network Performance with UCX. Collaboration between industry, laboratories, and academia to create an open-source, production-grade communication framework for data-centric and high-performance applications. Unified Communication X (UCX) is an award winning, optimized production proven communication framework for modern, high-bandwidth and low-latency networks. UCX exposes a set of abstract communication primitives which utilize the best of available hardware resources and offloads. These include RDMA (InfiniBand and RoCE), TCP, GPUs, shared Memory, and network atomic operations. UCX facilitates rapid development by providing a high-level API, masking the low-level details, while maintaining high-performance and scalability. UCX implements best practices for transfer of messages of all sizes, based on accumulated experience gained from applications running on the world’s largest datacenters and supercomputers. -

cpp-httplib
A C++ header-only HTTP/HTTPS server and client library
A C++11 single-file header-only cross-platform HTTP/HTTPS library. It's extremely easy to setup. Just include the httplib.h file in your code! This is a multi-threaded 'blocking' HTTP library. If you are looking for a 'non-blocking' library, this is not the one that you want. SSL support is available with CPPHTTPLIB_OPENSSL_SUPPORT. libssl and libcrypto should be linked. When using SSL, it seems impossible to avoid SIGPIPE in all cases, since on some operating systems, SIGPIPE can only be suppressed on a per-message basis, but there is no way to make the OpenSSL library do so for its internal communications. If your program needs to avoid being terminated on SIGPIPE, the only fully general way might be to set up a signal handler for SIGPIPE to handle or ignore it yourself. cpp-httplib officially supports only the latest Visual Studio. It might work with former versions of Visual Studio, but I can no longer verify it. -

µWebSockets
Compliant web server for the most demanding of applications
Being meticulously optimized for speed and memory footprint, µWebSockets is fast enough to do encrypted TLS 1.3 messaging quicker than most alternative servers can do even unencrypted, cleartext messaging. Furthermore, we partake in Google's OSS-Fuzz with a ~95% daily fuzzing coverage with no sanitizer issues. LGTM scores us flawless A+ from having zero CodeQL alerts and we compile with pedantic warning levels. µWebSockets is written entirely in C & C++ but has a seamless integration for Node.js backends. This allows for rapid scripting of powerful apps, using widespread competence. We've been fully standards compliant with a perfect Autobahn|Testsuite score since 2016. Companies with everything to lose rely on µWebSockets on a daily basis - we power the trading APIs of Bitfinex.com & Kraken.com, handling volumes of multiple billions of USD every day. Other companies include Trello, where µWebSockets is serving their 50 million users with real-time board updates. -

Pushpin
Proxy server for adding push to your API
Pushpin is a proxy server that pins client connections open, making it easy to build real-time API endpoints. Pushpin supports HTTP streaming, HTTP long-polling, and WebSockets. For compatibility with older browsers, it can also translate from SockJS. Clients communicate using your API contract. Pushpin is a server-side implementation detail. An existing real-time API can be migrated to or away from Pushpin without breaking clients. Since Pushpin is a proxy server, the backend can be written in any language. Convenience libraries are available to make integration easy. With Pushpin, API management systems can manage real-time endpoints. Authentication, analytics, etc. work as you'd expect. Pushpin listens on port 7999. Edit the routes file to point traffic to your backend. Make an endpoint on the backend that responds with instructional HTTP headers. -

lixa
LIXA, LIbre XA, is a free and open source XA transaction manager
LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages. -

LAppS
Lua Application Server for micro-services with default communication
This is an attempt to provide very easy-to-use Lua Application Server working over WebSockets protocol (RFC 6455). LAppS is an application server for micro-services architecture. It is build to be highly scalable vertically. The docker cloud infrastructure (kubernetes or swarm) shall be used for horizontal scaling. LAppS has most scallable WebSockets server out there. LAppS is the same thing to WebSockets as the Apache or Nginx are to HTTP. LAppS does not supports HTTP (though it supports HTTP Upgrade GET request as per RFC 6455). The only supported scripting language so far is the Lua. -
