Chronos is a replacement for cron. It is a distributed and fault-tolerant scheduler that runs on top of Apache Mesos that can be used for job orchestration. It supports custom Mesos executors as well as the default command executor. Thus by default, Chronos executes sh (on most systems bash) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the Mesos agents on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchronous callbacks to notify Chronos of job completion or failures. Chronos is also natively able to schedule jobs that run inside Docker containers.
Dkron is written in Go and leverage the power of distributed key-value stores and serf for providing fault tolerance, reliability and scalability while keeping simple and easily instalable. Dkron is inspired by the google whitepaper Reliable Cron across the Planet and by Airbnb Chronos borrowing the same features from it.
cronsun is a distributed cron-style job system. It's similar with crontab on stand-alone *nix. The goal of this project is to make it much easier to manage jobs on lots of machines and provides high availability. cronsun is different from Azkaban, Chronos, Airflow.
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.
Resilience4j is a lightweight fault tolerance library inspired by Netflix Hystrix, but designed for Java 8 and functional programming. Resilience4j provides higher-order functions (decorators) to enhance any functional interface, lambda expression or method reference with a Circuit Breaker, Rate Limiter, Retry or Bulkhead. You can stack more than one decorator on any functional interface, lambda expression or method reference. The advantage is that you have the choice to select the decorators you need and nothing else.
Bastion is a highly-available, fault-tolerant runtime system with dynamic, dispatch-oriented, lightweight process model. It supplies actor-model-like concurrency with a lightweight process implementation and utilizes all of the system resources efficiently guaranteeing of at-most-once message delivery. Bastion comes with a default one-for-one strategy root supervisor. You can use this to launch automatically supervised tasks.
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.
Official Elixir starting guide that will take you through the language foundations. You will also explore how to build projects with Mix and OTP, and it will introduce you to more advanvced techniques suchs as meta-programming. Adoption is more than programming. Elixir is an exciting new language, but to successfully get your application from start to finish, you’re going to need to know more than just the language. You need the case studies and strategies in this book. Learn the best practices for the whole life of your application, from design and team-building, to managing stakeholders, to deployment and monitoring. Go beyond the syntax and the tools to learn the techniques you need to develop your Elixir application from concept to production.
LizardFS Software Defined Storage is a distributed, parallel, scalable, fault-tolerant, Geo-Redundant and highly available file system. It spreads data over a number of physical servers, making it visible to an end user as a single file system.
And thats all! Now you can call incCounter on serverA, and check counter value on serverB - they will be synchronized.You can look at batteries implementation, examples and unit-tests for more use-cases. Also there is an API documentation. Feel free to create proposals and/or pull requests with new batteries, features, etc. Join our gitter chat if you have any questions.
This markdown file contains a list of academic papers (and other works) in the field of distributed consensus. Many of the papers listed below fit into more than one section. However, for simplicity, each paper is listed only in the most relevant section. Where possible, open access links for each paper have been provided. Contributions are welcome. This section lists theoretical results relating to distributed consensus.
Welcome to Ios, a reliable distributed agreement service for cloud applications. Built upon a novel decentralised consensus protocol, Ios provides vital services for your cloud application such as distributed locking, consistent data structures and leader election as well as distributed configuration and coordination.This repository is pre-alpha and under active development. APIs will be broken. This code has not been proven correct and is not ready for production deployment.
It is a productivity and fault tolerance enhancing team practice that has been utilized by professional software development teams at large corporations, such as Sears and Groupon. It provides the ability to wrap blocks of code with an abstract feature branch name, and then specify in a configuration file which features to be switched on or off.
Ganesha is PHP implementation of Circuit Breaker pattern which has multi strategies to avoid cascading failures and supports various storages to record statistics. It is one of the very active Circuit Breaker in PHP and production ready: well-tested, well-documented. 💪 You can integrate Ganesha to your existing code base easily as Ganesha provides just simple interface and Guzzle Middleware behaves transparency.
