Apache Kafka

Despite the disadvantages I list, I really believe that Kafka is the right choice whenever you need a queueing or message broker system. Kafka is way too battle-tested and scales too well to ever not consider it. The only exception is if your use case requires many, many small topics. Also, Kafka doesn't support delay queues out of the box and so you will need to "hack" it through special code on the consumer side.

WSO2 API Manager

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?

Pros

Apache Kafka

  • Apache Kafka is able to handle a large number of I/Os (writes) using 3-4 cheap servers.
  • It scales very well over large workloads and can handle extreme-scale deployments (eg. Linkedin with 300 billion user events each day).
  • The same Kafka setup can be used as a messaging bus, storage system or a log aggregator making it easy to maintain as one system feeding multiple applications.

Cons

Apache Kafka

  • Still a bit inmature, some clients have required recoding in the last few versions
  • New feaures coming very fast, several upgrades a year may be required
  • Not many commercial companies provide support

WSO2 API Manager

  • Installation of this product is a hell. You need to be an expert to get this running together with WSO2 Analytics. It uses a really confusing method of "port + 1" to connect extra products. I guess this was meant to provide a handy way to add new WSO2 products. In reality you'll need to scroll through numerous config files to set this straight. If you use this out of the box, everything will work all right. But the moment you add SSL certificates, DNS names and you'll need special ports to configure your firewall, this product becomes unmaintainable.
  • The "Store" provides a nice way to group API's. However, the "Publisher" does not... if you have more than 30 API's searching for API's becomes really annoying.
  • The number of configs in this product is huge. As a developer myself, I've never seen (and definitely never created) a product that needed that much config files. Installation and maintenance of products should be stupidly simple, since no developer nor infrastructure person wants to learn something that "just" needs to be a tool.. opposed to being a whole new area of expertise. After using WSO2 API Manager for a while, we wanted to change the admin password... this should be simple enough, like just change the password in "Carbon." But nope. The whole WSO2 environment crashed. We just gave up. Too dangerous.
  • Why so many different "products"? Publisher, Store, Carbon, and numerous hidden interfaces. Analytics, ESB whatever... No wonder there are so many config files and port issues. Make it simple!!!

Kafka is quickly becoming core product of the organization, indeed it is replacing older messaging systems. No better alternatives found yet

We are using the Apache open source version of Kafka. The community is a good place to ask questions. and we can get most of our problems resolved there.

I would only use RabbitMQ over Kafka when you need to have delay queues or tons of small topics/queues around.I don't know too much about Pulsar - currently evaluating it - but it's supposed to have the same or better throughput while allowing for tons of queues. Stay tuned - I might update this review after we finish evaluating Pulsar. It's much less battle-tested though.

IBM API Manager is a better enterprise wide tool.

Return on Investment

Apache Kafka

  • Positive impact on ROI since now we can use one large deployment of Apache Kafka that can be used for multiple scenarios ( storage systems, log aggregate, messaging queue ).
  • It is open-source so there are no licenses or subscription fees reducing the cost of deployment.
  • Data can now be ingested and analyzed in real-time making it easy to fine-tune the customer experience and decision making for internal IT.

WSO2 API Manager

  • 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.
