RabbitMQ
RabbitMQ is an open-source message-broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols. Written in Erlang, the RabbitMQ server is built on the Open Telecom Platform framework for clustering and failover. Client libraries to interface with the broker are available for all major programming languages. The source code is released under the Mozilla Public License. History Originally developed by Rabbit Technologies Ltd. which started as a joint venture between LShift and CohesiveFT in 2007, RabbitMQ was acquired in April 2010 by SpringSource, a division of VMware. The project became part of Pivotal Software in May 2013. The project consists of: *The RabbitMQ exchange server *Gateways for AMQP, HTTP, STOMP, and MQTT protocols ...

AMQP
The Advanced Message Queuing Protocol (AMQP) is an open standard application layer protocol for message-oriented middleware. The defining features of AMQP are message orientation, queuing, routing (including point-to-point and publish-and-subscribe), reliability and security. AMQP mandates the behavior of the messaging provider and client to the extent that implementations from different vendors are interoperable, in the same way as SMTP, HTTP, FTP, etc. have created interoperable systems. Previous standardizations of middleware have happened at the API level (e.g. JMS) and were focused on standardizing programmer interaction with different middleware implementations, rather than on providing interoperability between multiple implementations. Unlike JMS, which defines an API and a set of behaviors that a messaging implementation must provide, AMQP is a wire-level protocol. A wire-level protocol is a description of the format of the data that is sent across the network as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mozilla Public License
The Mozilla Public License (MPL) is a free and open-source weak copyleft license for most Mozilla Foundation software such as Firefox and Thunderbird The MPL license is developed and maintained by Mozilla, which seeks to balance the concerns of both open-source and proprietary developers; it is distinguished from others as a middle ground between the permissive software BSD-style licenses and the General Public License. So under the terms of the MPL, it allows the integration of MPL-licensed code into proprietary codebases, but only on condition those components remain accessible. MPL has been used by others, such as Adobe to license their Flex product line, and The Document Foundation to license LibreOffice 4.0 (also on LGPL 3+). Version 1.1 was adapted by several projects to form derivative licenses like Sun Microsystems' Common Development and Distribution License. It has undergone two revisions: the minor update 1.1, and a major update version 2.0 nearing the goals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pivotal Software
Pivotal Software, Inc. was an American multinational software and services company based in San Francisco that provided cloud platform hosting and consulting services. Since December 2019, Pivotal has been part of VMware. History Pivotal Software was formed in 2012 after spinning out of EMC Corporation and VMware (which was majority-owned by EMC). The name came from the Pivotal Labs LLC which had been acquired by EMC, and briefly used the name GoPivotal, Incorporated. On April 24, 2013, the organization announced a investment from General Electric (for 10% equity) and Pivotal One, including Cloud Foundry for cloud computing. Paul Maritz became Pivotal's chief executive immediately after the spin-out. Maritz had joined EMC in February 2008 when Pi Corporation, a company he co-founded, was acquired and was previously the CEO of VMware. The Greenplum Database (acquired by EMC in 2010) formed the basis of a division selling software for the big data market. In March 2013, a d ...

Open Telecom Platform
OTP is a collection of useful middleware, libraries, and tools written in the Erlang programming language. It is an integral part of the open-source distribution of Erlang. The name OTP was originally an acronym for Open Telecom Platform, which was a branding attempt before Ericsson released Erlang/OTP as open source. However neither Erlang nor OTP is specific to telecom applications. The OTP distribution is supported and maintained by the OTP product unit at Ericsson, who released Erlang/OTP as open-source in the late 90s, to ensure its independence from a single vendor and to increase awareness of the language. It contains: *an Erlang interpreter (which is called '' BEAM''); *an Erlang compiler; *a protocol for communication between servers (nodes); *a CORBA Object Request Broker; *a static analysis tool called Dialyzer; *a distributed database server (Mnesia); and *many other libraries.

Apache Kafka
Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. Kafka can connect to external systems (for data import/export) via Kafka Connect, and provides the Kafka Streams libraries for stream processing applications. Kafka uses a binary TCP-based protocol that is optimized for efficiency and relies on a "message set" abstraction that naturally groups messages together to reduce the overhead of the network roundtrip. This "leads to larger network packets, larger sequential disk operations, contiguous memory blocks ..which allows Kafka to turn a bursty stream of random message writes into linear writes." History Kafka was originally developed at LinkedIn, and was subsequently open sourced in early 2011. Jay Kreps, Neha Narkhede and Jun Rao helped co-create ...

MQTT
MQTT (originally an initialism of MQ Telemetry Transport) is a lightweight, publish-subscribe, machine to machine network protocol for Message queue/Message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth. It must run over a transport protocol that provides ordered, lossless, bi-directional connections—typically, TCP/IP. It is an open OASIS standard and an ISO recommendation (ISO/IEC 20922). History Andy Stanford-Clark ( IBM) and Arlen Nipper (then working for Eurotech, Inc.) authored the first version of the protocol in 1999. It was used to monitor oil pipelines within the SCADA industrial control system. The goal was to have a protocol that is bandwidth-efficient, lightweight and uses little battery power, because the devices were connected via satellite link which, at that time, was extremely expensive. Historically, the "MQ" in "MQTT" came from the IBM MQ (then 'MQSeries') pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erlang (programming Language)
Erlang ( ) is a general-purpose, concurrent, functional programming language, and a garbage-collected runtime system. The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang programs. The Erlang runtime system is designed for systems with these traits: *Distributed *Fault-tolerant * Soft real-time * Highly available, non-stop applications *Hot swapping, where code can be changed without stopping a system. The Erlang programming language has immutable data, pattern matching, and functional programming. The sequential subset of the Erlang language supports eager evaluation, single assignment, and dynamic typing. A normal Erlang application is built out of hundreds of small Erlang processes. It was originally proprietary software within Ericsson, developed by Joe Armstrong, Robert Virding, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpringSource
Spring (previously known as SpringSource) was the company created by the founders of the Spring Framework (a programming model for enterprise Java applications) to support and develop Spring and related projects. Originally incorporated as Interface 21, it was renamed SpringSource in 2008 to better reflect its main business. Over time most of the Spring developers were employed full-time by the company which offered training and consulting services to finance its activities (Spring itself is open source and is freely available to all). The company was then renamed as Spring. Recognizing that the platform of choice for most Spring applications was Apache Tomcat, Spring merged with Covalent on January 29, 2008. Like Spring, Covalent was the financial vehicle supporting some of the developers of Tomcat. Several other acquisitions followed: G2One (the company behind Groovy and Grails), Hyperic (who developed a tool for monitoring Java applications and their environment) and Clou ...

Streaming Text Oriented Messaging Protocol
Simple (or Streaming) Text Oriented Message Protocol (STOMP), formerly known as TTMP, is a simple text-based protocol, designed for working with message-oriented middleware (MOM). It provides an interoperable wire format that allows STOMP clients to talk with any message broker supporting the protocol. Overview The protocol is broadly similar to HTTP, and works over TCP using the following commands: *CONNECT *SEND *SUBSCRIBE *UNSUBSCRIBE *BEGIN *COMMIT *ABORT *ACK *NACK *DISCONNECT Communication between client and server is through a "frame" consisting of a number of lines. The first line contains the command, followed by headers in the form : (one per line), followed by a blank line and then the body content, ending in a null character. Communication between server and client is through a MESSAGE, RECEIPT or ERROR frame with a similar format of headers and body content. Example SEND destination:/queue/a content-type:text/plain hello queue a ^@ Implementations Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
