Likelihood to Recommend It's free! No argument can win a fight with that! And it's the only reason I gave it a 5. If you have no money to spend, and a simple environment you'll have a nice product. But free does come with a price. After 5 years we're still struggling with ports, and analytics (it just won't work without any errors caused by some configuration somewhere). An API Manager should work out of the box. The only configuration expertise that any developer wants to invest in, is the configuration of API's. Not the product itself... Anyone who've seen the training material, just for installing this thing will agree that this is not the way to go. Of all the API Managers out there (we've tried 4), WSO2 is the only one were you need to know how this dragon of a java application works internally. Did I already mention the humongous amount of config files?
Read full review WSO2 ESB is an awesome product for companies looking to venture into the world of SOA with an ESB. They have a lot of other products too that can work really well with their carbon infrastructure. The interface is simple for deploying and managing proxy services. You can also write custom modules within the ESB using Java with IDE like Eclipse
Read full review Pros Authentication based on OAuth 2.0 and HTTP Basic Authentication. Rate Limiting applied at different levels like Subscriber, API, Resource and Backend. Monitoring by exporting the metrics in Prometheus and traces in Jaeger. Mediation to perform transformation, orchestration etc. Read full review One of the basic requirement of an ESB product is that it should be able to support transformation. WSO2 ESB provides support of XSLT, so you can transform your request to whatever format. Moreover, transformations like converting your xml payload into JSON and JSON payload to XML are out of the box available. WSO2 ESB provides a scheduler feature, by which you can configure your own scheduler to call a proxy service at a particular time of day or or initiate sequence. WSO2 ESB provides excellent error handling techniques, WSO2 ESB provides detailed error handling scenarios to tackle all the situations. WSO2 ESB also provides custom error handling by which you can make your own custom error message before sending it back to client. Read full review Cons Better QA testing prior to releases rollout Better support needed Read full review While it's easy to configure for a quick start, it is not so easy to deploy by yourself in a complex production scenario. Not very stable for production usage, we encountered several trivial bugs that make us believe that this product is still not widely adopted. Lack of a built in mechanism for auto-restart in case of an application server crash. Read full review Usability Compared to competitors the overall experience has been fine
Read full review Reliability and Availability Lack of auto-restart built-in capabilities. In case of running out of memory there are no built-in methods to recover from a crash, just for example, Oracle WebLogic Node Manager.
Read full review Performance The product is performing well and consuming few resources
Read full review Support Rating Our experience with the WSO2 support has beent satisfactory
Read full review Alternatives Considered Providing better capabilities comparing the overall API lifecycle management, especially the availability of API Integration layer and a strong identity layer of their own which provides an end-to-end API ecosystem that would be advantageous in terms of a large software development initiative.
Read full review It's the only one truly open source and free.
Read full review Scalability Adding a server node is really straightforward, there are just few point in the configuration files.
Read full review Return on Investment We've moved away from legacy SOAP services where nobody knew what services was used by who. WSO2 eliminated at least 90% of time spend on any service. Creating API's (or actually creating the API Management layer...) is so simple that new developers can get away with it in no time. Again, real time gainer. Since creating API's is so simple, developers are very fast in adopting a kind of "Domain thinking". In comparison with Azure API Manager: Azure does not demand knowledge of "how" the product works, but it's definitely more difficult to get an API up and running in Azure. And for some reason, azure does not promote clean domain driven architecture. Domain Driven architecture is the greatest time saver strategy possible. And WSO2 fits nicely in there. Read full review Very well documented tutorials and case studies makes it easy to learn. It has a really supportive community It is fast and it can easily handle 300 tps of average use on a VM with 4Gig RAM Read full review ScreenShots
