The docs linked from product page are 404ing. Ex: https://cloud.google.com/filestore/docs/quickstart-gcloud

Is it intentional that on the page, there's a list of Partner Solutions that are essentially a competitor of Filestore?

Extreme "Just my two cents" mode: user problems may be similar, but needs and solutions remain unique.

Any one group trying to build a solution to serve all needs is likely in line for complication, which is why great partners and options continue to be a wise choice.

(Gonna duck out of this thread, etc. now since this isn't my release and I assume people who work in storage can go a lot deeper.)

They all nominally do the same thing but they all have their pros and cons.

It’s like choosing which car to buy. They all get you from A to B, but there are still many options to choose from. ;)

They are trying to be nice to the partners they are now competing with.

I think these are the solutions that GCP Partners have created USING Filestore.

No, they are alternatives that have existed as solutions before Filestore was created. They still have unique features, better performance and other advantages if you need them.
