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.

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.

Pacemaker is a high-availability cluster resource manager.

It achieves maximum availability for your cluster services (a.k.a. resources) by detecting and recovering from node- and resource-level failures by making use of the messaging and membership capabilities provided by Corosync.

It can do this for clusters of practically any size and comes with a powerful dependency model that allows the administrator to accurately express the relationships (both ordering and location) between the cluster resources.

Virtually anything that can be scripted can be managed as part of a Pacemaker cluster.

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.

This package implements a Raft algorithm logic (no I/O and no system calls). On top of that, various drivers are provided that implement actual network communication and persistent data storage.

The core part of the library is designed to work well with asynchronous or non-blocking I/O engines (such as libuv and io_uring), although it can be used in threaded or blocking contexts as well.

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.

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.

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.
