WSO2 (sometimes stylized as WSO2) is an open source application development software company focused on providing service-oriented architecture (SOA) solutions for professional developers. Coming quickly after an investment in Collax, an open source Linux server provider, Intel Capital has invested $4 million into WSO2, a global corporation with offices located in USA (Mountain View, CA; Bloomington, IN), UK (London) and Sri Lanka (Colombo). WSO2 was founded by Dr. Sanjiva Weerawarana and Paul Fremantle in August, 2005.

WSO2 projects are free and open source released under Apache License Version 2.[2] It follows open development principles and the architecture and development discussions are carried out through WSO2's public mailing lists. WSO2's annual conferences, named "WSO2Con", are held in Europe, USA, and Asia, to discuss about SOA, Cloud Computing, IT strategies, and applications,[3] apart from the series of free webinars on the related topics.

Products

WSO2 Carbon

WSO2 Carbon is an SOA middleware platform from WSO2. Built on OSGi, Carbon encapsulates major SOA functionality[4] such as data services, business process management, ESB routing/transformation, rules, security, throttling, caching, logging and monitoring. WSO2 products such as Application Server, Enterprise Service Bus, and Business Process Server are built on top of the WSO2 Carbon middleware platform. The WSO2 products are available to download, or can be custom-built by adding the components on top of the Carbon core.

WSO2 Stratos

WSO2 Stratos is a cloud middleware platform built on WSO2 Carbon.[5] WSO2 StratosLive is the publicly hosted Java Platform as a Service(PaaS) of WSO2 Stratos, deployed over Amazon Infrastructure as a Service,[6] letting the users to register an account of free or paid account types, based on their requirements. WSO2 Stratos is a polyglot PaaS and enables the WSO2 Carbon middleware platform and other languages or runtime environments to run on the cloud.[7]

WSO2 Identity Server

The WSO2 Identity Server is an open source identity & entitlement management server having support for Information Cards, OpenID and XACML.

WSO2 Enterprise Service Bus

The WSO2 Enterprise Service Bus (ESB) is a enterprise service bus (ESB) based on the Apache Synapse enterprise service bus, providing management and development/configuration support and SOA Governance capabilities. Ebay uses WSO2 Enterprise Service Bus as one of the key elements in its transaction software, which continuously executes $2,000 worth of transactions per second.[8]

WSO2 Enterprise Service Bus supports the creation of Proxy Services graphically, which allows users to create virtual services on the ESB layer to front existing services. Existing services are SOAP, Plain Old XML (POX)/REST services over HTTP/S, as well as SOAP or legacy services over JMS, Apache VFS file systems (e.g. s/ftp, file, zip/tar/gz, webdav, and cifs), Mail systems (such as Post Office Protocol (POP3), Internet Message Access Protocol (IMAP), and Simple Mail Transfer Protocol (SMTP)), Financial Information eXchange (FIX), Hessian, and Advanced Message Queuing Protocol (AMQP).

WSO2 Enterprise Service Bus takes advantage of the non-blocking https transport implementation built by Apache Synapse ESB over the Apache HttpComponents/NIO module, to handle thousands of concurrent requests using very little resources and threads. The implementation is capable of connection throttling to control the rate at which large messages are read and processed, and thus can handle heavy concurrent loads of large messages using constant memory.

WSO2 Enterprise Service Bus also supports clustered deployments, with support for load balancing, throttling, and caching over clustered deployments. The integration with the embedded WSO2 Governance Registry or an external Registry/Repository allows WSO2 Enterprise Service Bus to use externally defined resources for mediation, as well as save its configuration into an externally managed Registry/Repository for improved SOA governance. WSO2 Enterprise Service Bus can be extended with custom Java extensions or POJO classes, or via Apache BSF scripting languages such as JavaScript, Ruby, and Groovy. WSO2 Enterprise Service Bus ships with over 55 samples that can be executed out of the box.

The proxy services allow switching of transport, interface (WSDL/Schema/Policy), message format (SOAP 1.1, 1.2/POX/REST, Text, and Binary/Hessian), QoS (WS-Addressing, WS-Security, and WS-Reliable Messaging) and message optimization (MTOM/SwA).

WSO2 Application Server

WSO2 Application Server is an enterprise-ready Web services engine powered by Apache Axis2. It is a low-footprint platform for service-oriented architectures, enabling business logic and applications. Bringing together a number of Apache Web services projects, WSO2 Application Server provides a reliable runtime for deploying and managing Web services.

WSO2 Business Process Server

WSO2 Business Process Server (BPS) is a Business Process Server that executes business processes written following WS-BPEL standard. WS-BPEL is emerging as the de facto standard for composing multiple synchronous and asynchronous web services into collaborative and transactional process flows which increase the flexibility and agility of a service-oriented architecture. WSO2 BPS is powered by Apache ODE (Apache Orchestration Director Engine). WSO2 BPS provides a complete Web-based graphical console to deploy, manage and monitor business process and process instances. Some of the key features are


WSO2 Governance Registry

WSO2 Governance Registry is an enterprise-ready open source product for governing SOA deployments. With WSO2 Governance Registry, you can store, catalog, index and manage your enterprise metadata in a simple and scalable model.

WSO2 Data Services Server

WSO2 Data Services Server provides a convenient Web service interface for data stored in sources such as relational databases, CSV files & MS-Excel files. With WSO2 Data Services Server, data can be exposed and accessed in a secure (using WS-Security) and reliable (using WS-ReliableMessaging) manner; data is also made available for mashing-up with other Web services.

WSO2 Business Activity Monitor

The WSO2 Business Activity Monitor is a Business Activity Monitor designed to monitor and understand business activities within a SOA deployment, which also can be extended to cater for other general monitoring requirements.

WSO2 Gadget Server

The WSO2 Gadget Server is an Enterprise Information Portal, providing a framework built on top of the Google Gadget Specification, that helps enterprises organize information in their SOA across organizational boundaries.

WSO2 Business Rules Server

WSO2 Business Rules Server uses SOA to provide the service to clients, separating the business logic from the infrastructure code. WSO2 Business Rules Server allows business rules to be encapsulated in a simpler, more direct and accessible dialect focusing the business analysts.

WSO2 Web Service Framework

WSO2 Web Services Framework is a framework for web services, based on Apache Axis2/C and several related packages. It has bindings for a number of languages, including C, PHP, Java, Ruby, and more.

WSF/C

This module is an integration of the Apache modules

WSF/C is included in most non-Java bindings. Rather than requiring the relevant Apache packages, their distribution includes an outdated copy of them. This is consistent with the company's purpose to support and test portability and interoperability,[9] additionally providing Windows binaries, so as to boost deployment.

WSF/PHP

The PHP binding is built on top of WSF/C. It is a shared object (a.k.a. dynamic-link library) that is loaded as a PHP extension on start up. It defines a number of classes, including WSClient, WSClientProxy, WSService, WSMessage, WSHeader, WSFault, WSSecurityToken, WSPolicy, that can be readily used in PHP scripts, without requiring additional interpreted code to be loaded on each request.

Features like responding to any SOAP version as well as REST requests, latest WS-* specification, and .NET compatibility, make this a rather unique PHP library.[10]
