0、WSO2 API Manager概述

作为一个实现SOA的机构，可以通过暴露核心流程、数据和api服务给公众而获取利益。外部机构可以以创新的方式组合、混搭这些API构造出新的解决方案。

一个企业可以通过其简单的，分散API的方式促进发展的动力来增加其增长潜力和伙伴关系的进步。

然而，以协作的方式利用API在行使控制，建立信任，安全和监管等方面引入了新的挑战。因此，适当的API管理是至关重要的。

WSO2 API Manager使用一系列API创建、发布、生命周期管理、版本化、货币化、治理、安全等功能来克服这些挑战。

WSO2 API Manager overcomes these challenges with a set of features for API creation, publication, lifecycle management, versioning, monetization, governance, security etc. using proven WSO2 products such as WSO2 Enterprise Service Bus, WSO2 Identity Server, and WSO2 Governance Registry. In addition, it is also powered by the WSO2 Data Analytics Server and is immediately ready for massively scalable deployments.

WSO2 API Manager is fully open source and is released under Apache Software License Version 2.0, one of the most business-friendly licenses available today. It provides Web interfaces for development teams to deploy and monitor APIs, and for consumers to subscribe to, discover and consume APIs through a user-friendly storefront. The API Manager also provides complete API governance and shares the same metadata repository as WSO2 Governance Registry. If your setup requires to govern more than APIs, we recommend you to use WSO2 API manager for API governance and WSO2 Governance Registry for the other artefacts. That the default communication protocol of the Key Manager is Thrift.

The WSO2 API Manager is an on-going project with continuous improvements and enhancements introduced with each new release to address new business challenges and customer expectations. WSO2 invites users, developers and enthusiasts to get involved or get the assistance of our development teams at many different levels through online forums, mailing lists and support options.
