HAProxy - The Reliable, High Performance TCP/HTTP Load Balancer

HAProxy is a fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware.

orchestrator - MySQL replication topology management and HA

orchestrator actively crawls through your topologies and maps them. It reads basic MySQL info such as replication status and configuration.It provides with slick visualization of your topologies, including replication problems, even in the face of failures.

serf - Service orchestration and management tool

Serf is a decentralized solution for service discovery and orchestration that is lightweight, highly available, and fault tolerant.Serf runs on Linux, Mac OS X, and Windows. An efficient and lightweight gossip protocol is used to communicate with other nodes. Serf can detect node failures and notify the rest of the cluster. An event system is built on top of Serf, letting you use Serf's gossip protocol to propagate events such as deploys, configuration changes, etc. Serf is completely masterless with no single point of failure.

Akka - Build Concurrent and Scalable Applications

Akka is the platform for the next generation event-driven, scalable and fault-tolerant architectures on the JVM. It helps to write simpler correct concurrent applications using Actors, STM & Transactors. It could scale out on multi-core or multiple nodes using asynchronous message passing. For fault-tolerance it adopts the Let it crash or Embrace failure model to build applications that self-heals, systems that never stop.

OpenCDN - Content Delivery Network

OpenCDN aims at the development of an application-level Content Delivery Network, suitable for replication and splitting of live and recorded multimedia content. It uses Relay technology, which splits incoming media packets for each downstream flow. Media distribution is hierarchically arranged among participating Nodes, coordinated by a centralized control unit.

Coral CDN- Content Distribution Network

Coral is a peer-to-peer content distribution network. Sites that run Coral automatically replicate content. Using modern peer-to-peer indexing techniques, CoralCDN will efficiently find a cached object if it exists anywhere in the network.

evQueue - Job scheduler and queueing engine

evQueue is an open source job scheduler and queueing engine. It features an event-driven C++ engine and a PHP / MySQL web control interface which provides tasks monitoring and creation. It provides both simple task execution and complex task chaining (workflow) using an easy to use drag & drop web interface. Workflow description includes output linking to input, conditions, loops... Queues management provides an easy way for task parallelization and resource control.

freno - freno: cooperative, highly available throttler service

Cooperative, highly available throttler service: clients use freno to throttle writes to a resource.Current implementation can throttle writes to (multiple) MySQL clusters, based on replication status for those clusters. freno will throttle cooperative clients when replication lag exceeds a pre-defined threshold.

spilo - Highly available elephant herd: HA PostgreSQL cluster using Docker

Spilo is a Docker image that provides PostgreSQL and Patroni bundled together. Patroni is a template for PostgreSQL HA. Multiple Spilos can create a resilient High Available PostgreSQL cluster. For this, you'll need to start all participating Spilos with identical etcd addresses and cluster names.Spilo's setup assumes that you've correctly configured a load balancer (HAProxy, ELB, Google load balancer) that directs client connections to the master. There are two ways to achieve this: A) if the load balancer relies on the status code to distinguish between the healthy and failed nodes (like ELB), then one needs to configure it to poll the API URL; otherwise, B) you can use callback scripts to change the load balancer configuration dynamically.
