NATS is a simple, secure and performant communications system for digital systems, services and devices. NATS is part of the Cloud Native Computing Foundation (CNCF). NATS has over 40 client language implementations, and its server can run on-premise, in the cloud, at the edge, and even on a Raspberry Pi. NATS can secure and simplify design and operation of modern distributed systems.

cowsql (/ˈkaʊ,siːkwəl/ listen) is a C library that implements an embeddable and replicated SQL database engine with high availability and automatic failover.

cowsql extends SQLite with a network protocol that can connect together various instances of your application and have them act as a highly-available cluster, with no dependency on external databases.

HAProxy offers HA, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited to Web sites crawling under very high loads while needing persistence or Layer 7 processing. Supporting tens of thousands of connections is clearly realistic with today's hardware.

The Corosync Cluster Engine is a Group Communication System with additional features for implementing high availability within applications. The project provides four C Application Programming Interface features:

• A closed process group communication model with extended virtual synchrony guarantees for creating replicated state machines.

• A simple availability manager that restarts the application process when it has failed.

• A configuration and statistics in-memory database that provide the ability to set, retrieve, and receive change notifications of information.

• A quorum system that notifies applications when quorum is achieved or lost.

NSQ is a realtime distributed messaging platform designed to operate at scale, handling billions of messages per day.

Key features:

• support distributed topologies without SPOF

• scale horizontally (no brokers, seamlessly add more nodes to the cluster)

• low-latency push based message delivery (performance)

• combine load-balanced and multicast style message routing

• excel at both streaming (high-throughput) and job oriented (low-throughput) workloads

• primarily in-memory (beyond a high-water mark messages are transparently kept on disk)

• runtime discovery service for consumers to find producers (nsqlookupd)

• transport layer security (TLS)

• data format agnostic

• few dependencies (easy to deploy) and a sane, bounded, default configuration

• simple TCP protocol supporting client libraries in any language

• HTTP interface for stats, admin actions, and producers (no client library needed to publish)

• integrate with StatsD for realtime instrumentation

• robust cluster administration interface (nsqadmin)

Kronosnet, often referred to as knet, is a network abstraction layer designed for High Availability use cases, where redundancy, security, fault tolerance and fast fail-over are the core requirements of your application.

Kronosnet is the new underlying network protocol for Linux HA components (Corosync), that features ability to use multiple links between nodes, active/active and active/passive link failover policies, automatic link recovery, FIPS compliant encryption (nss and/or openssl), automatic PMTUd and in general better performances compared to the old network protocol.

Libqb is a library with the primary purpose of providing high-performance, reusable features for client-server architecture, such as logging, tracing, IPC and polling. Libqb is not intended to be an all-encompassing library, but instead provide focused APIs that are highly tuned for maximum performance for client-server applications.

Hugs 98 is an interpreter and programming environment for developing Haskell programs. It provides an almost complete implementation of Haskell 98, which includes expression and pattern syntax, primitives for monadic I/O, with support for simple interactive programs, handle-based I/O, and exception handling. Hugs has a nearly complete implementation of the Haskell module system and supports a number of advanced extensions.
