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.

Tars - Tars is a highly performance rpc framework based on naming service using tars protocol and provides a semi-automatic operation platform


Tars comes from the robot in Interstellar movie. Tars is a high-performance RPC framework based on name service and Tars protocol, also integrated administration platform, and implemented hosting-service via flexible schedule. Tars, aka TAF(Total Application Framework), has been used in Tencent since 2008. It supports C++,Java,Nodejs and php for now. This framework offers a set of solution for development, maintenance and testing, which making develop, deploy and testing service efficiently. It integrated extensible protocol for encoding/decoding, high-performance RPC communication framework, name service, monitor, statistics and configuration. You can use it to develop your reliable distributed application based on microservice fast, and reach fully efficient service management.

thanos - Highly available Prometheus setup with long term storage capabilities.


Thanos is a set of components that can be composed into a highly available metric system with unlimited storage capacity. It can be added seamlessly on top of existing Prometheus deployments and leverages the Prometheus 2.0 storage format to cost-efficiently store historical metric data in any object storage while retaining fast query latencies. Additionally, it provides a global query view across all Prometheus installations and can merge data from Prometheus HA pairs on the fly.


keepalived - Keepalived


The main goal of the keepalived project is to add a strong & robust keepalive facility to the Linux Virtual Server project. It implements a multilayer TCP/IP stack checks. Keepalived implements a framework based on three family checks : Layer3, Layer4 & Layer5. This framework gives the daemon the ability of checking a LVS server pool states. Keepalived can be sumarize as a LVS driving daemon. Keepalived implementation is based on an I/O multiplexer to handle a strong multi-threading framework. All the events process use this I/O multiplexer.

Cobar - Proxy for sharding databases and tables


Cobar is a proxy for sharding databases and tables,compatible with MySQL protocal and MySQL SQL grama,underlying storage only support MySQL for support foreground business more simple,stable,efficient and safety。

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.

kube-aws - Kubernetes on AWS


Note: The master branch may be in an unstable or even broken state during development. Please use releases instead of the master branch in order to get stable binaries.kube-aws is a command-line tool to create/update/destroy Kubernetes clusters on AWS.

Ribbon - IPC library with built in software load balancers


Ribbon is a client side IPC library that is battle-tested in cloud. It provides Load balancing, Fault tolerance, Multiple protocol (HTTP, TCP, UDP), support in an asynchronous and reactive model Caching and batching.

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.

kubeadm-ha - Kubernetes high availiability deploy based on kubeadm (for v1


kube-apiserver: exposes the Kubernetes API. It is the front-end for the Kubernetes control plane. It is designed to scale horizontally – that is, it scales by deploying more instances. etcd: is used as Kubernetes’ backing store. All cluster data is stored here. Always have a backup plan for etcd’s data for your Kubernetes cluster. kube-scheduler: watches newly created pods that have no node assigned, and selects a node for them to run on. kube-controller-manager: runs controllers, which are the background threads that handle routine tasks in the cluster. Logically, each controller is a separate process, but to reduce complexity, they are all compiled into a single binary and run in a single process. kubelet: is the primary node agent. It watches for pods that have been assigned to its node (either by apiserver or via local configuration file) kube-proxy: enables the Kubernetes service abstraction by maintaining network rules on the host and performing connection forwarding. keepalived cluster config a virtual IP address (192.168.20.10), this virtual IP address point to k8s-master01, k8s-master02, k8s-master03. nginx service as the load balancer of k8s-master01, k8s-master02, k8s-master03's apiserver. The other nodes kubernetes services connect the keepalived virtual ip address (192.168.20.10) and nginx exposed port (16443) to communicate with the master cluster's apiservers.

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.
