Just a little utility service for dealing with ARNs
If I’m understanding this correctly, it’s a utility to build ARNs from components or break ARNs into their constituent components. Out of curiosity, why is this a service and not a library? Is it just to make it (more) accessible to other languages?
Correct, that’s what it does. It’s really just the online version of what is available in the AWS SDK. I like to have small services that I can invoke and compose on the CLI, only having curl as the dependency. Same way that I query my public IP using curl ifconfig.co ;)
A question I have in this context is: Is the granularity and abstraction you gain worth the overhead in both complexity and performance?
Worth it? Not sure. What would be the complexity?
Well, let’s compare and contrast.
A library call has virtually no overhead. You’re running code on your machine. Full stop.
Creating a microservice adds the following levels of indirection:
And that’s just off the top.
Re-reading my responses to this, I have done exactly what I hate to see in other people’s posts. I allowed myself to go off half cocked based on my initial idea of “Why write a service for this when you can just call the SDK?” when there are clearly PLENTY of people who have many uses for this service.
I can only say that I will try to exhibit the kind of open mindedness I’d like to see in others in my future reactions to posts here.
