WSO2 is not for companies who want quick results from start. You need your organization - not just developers, even directors to get their hands dirty when need comes. It takes time to mature - then you can expect good results.

I've trained 100+ people in using the API Manager and it is my favorite of the 4 products from WSO2. IT works with all of the other products from WSO2. (IS as external Keymanager, EI as the mediation engine), BPS as the workflow engine) and Stream Processor (as the traffic manager and / or Analytics Server).

WSO2 API Management solution is used in one of the projects to enable API Access Control using in-built Auth Provider, publish, discover and subscribe APIs using simple, elegant, intuitive in-built Portals. Besides that, WSO2 API Management solution offers support for caching, traffic control & version control like every other API Manager at an enterprise grade but under open source umbrella. Though the product can be used free of cost under open source licensing, it is recommended to get a subscription which brings in a lot of support & services including early security patches and upgrades.

This application is open source, very reliable and lightweight. Actually It helped me to gain my skills and knowledge about handling API's within very short period of time. Any type of user can easily work with this tool( It comes with tutorials ). I have couple of years of experience with API management and this is the best choice I ever made. If you're using this amazing tool, it's not difficult to deploy and manage API's anymore. It comes with API store, API designing & deploying functionalities, user permissions, security controls, usage monitoring functionalities and many more.
