I had started to publish about DataPower earlier, and I intend to continue to share more knowledge about it. However, I will change my post priorities by the importance I have seen in API Management concept lately.
Before my API Connect journey, I suggest you read two good IBM articles, in which API Management and ESB purpose, and related operational responsibilities are discussed.
An ESB is not API Management
Several years into the era of APIs and still one of the most common points of confusion is the positioning of APIs and…
Is a Combined ESB and API Management a Good Idea?
What if you took all of the API Management functionality that is not in a traditional ESB and added it to the ESB as a…
My API Connect journey began at the moment I thought my DataPower journey ends.
My mission: expose SOAP services into REST with JSON.
I had already created several routes using DataPower following that structure:
- filter requests;
- change the REST request methods such as GET and PUT to POST SOAP requests;
- transform my request to SOAP envelope with the “text editor” (hi IBM, kindly improve the layer of XSLT editing in DataPower);
- invoke SOAP services and routing the response and faults;
- transform response via XSLT to JSONX;
- transform JSONX to JSON.
Yes, something very easy…
When I went to publish into the production environment, a definition: The exposure for Internet APIs will be provided by API Connect.
I had even seen how to implement OAuth into DataPower, and at first, I had not understood how the concept of an API Management would interfere with my application. I still believed it would be much easier to make the transformations into an ESB and continue exposing the routes via DataPower … a mistake that I intend to show you during this series.
The work I did in DataPower Multi-Protocol ended up losing, but as time went by, I started to understand how DataPower and API Connect relate themselves. When we install API Connect into a Docker image, you could see that the DataPower image will also be present, and then the integration between these two tools will become clearer.
Well, I will finish this post here, the next I will explain a bit better the API Connect proposal.
See you next time!
PS: I intend to improve my written English, so if you find out some mistake, please, notify me.
