ChatGPT: Azure Active Directory B2C vs Duende IdentityServer
I recently did an analysis of authorization and identity solutions for use in a specific software application. I researched underlying technologies, solution providers, and all kinds of other information to make the best decision that I could as well as present that information in a helpful manner to the rest of my team for them to weigh in on the discussion.
One of the deliverables was this blog post: Showdown: Azure Active Directory B2C vs Duende IdentityServer (I tried to be thorough on the points that mattered to us but I did not spend a lot of time cleaning it up).
However, my team has recently been experimenting a little deeper with ChatGPT, OpenAI, and other AI solutions so I wondered how effecitve ChatGPT would be at providing this type of analysis for me.
For my first prompt, I asked a moderately generic question and allowed ChatGPT to select the evaluation criteria. I then followed that up with a second message asking it to evaluate the two solutions using the same set of criteria that I used in my own analysis.
Here is the raw and unedited result, recorded for the sake of interest and comparison. I will not vouch for the accuracy or helpfulness of any of this information but it is interesting to see the quality of analysis that may be accomplished in just a few minutes with ChatGPT.
