In general I'm in favor of more ad-hoc project-specific teams rather than
completely siloing every service to the Services group, or every mobile UI to the Mobile group.= Agreed, as long as everyone deploying services communicates through services team so there is no duplication of solutions. We should have 1 routing layer, standard monitoring and standard caching as it is been pointed out before. Specifics of services might be different but it seems the core mission of service team to provide common infrastructure, right?. That means that the 1st service we develop will be more work for services team than subsequent services. *Ideally* the mobile team should develop the service without having to solve (for example) any caching problems that are not mobile specific.

I strongly agree. Based on experience on both sides of this spectrum, I recommend (when feasible) favoring feature teams over functional teams.

(Note that the state of the art is that Mobile Apps are using Mobile
Web's
MobileFrontend extension as an intermediate API to aggregate & format
page
data -- which basically means Max has done the server-side API work for Mobile Apps so far.)
I'd expect to see Max and/or someone else from the Mobile team collaborating with the Services team to create what y'all need:
- something that does what Mobile Apps needs it to...
- and can be maintained like Services needs it to.

Regarding general-purpose APIs vs. mobile: I think mobile is in some

special case as their content transformation needs are closely
coupled
with
the way the apps are presenting the content. Additionally, at least
until
SPDY is deployed there is a strong performance incentive to bundle information in a single response tailored to the app's needs. One
strategy
employed by Netflix is to introduce a second API layer <

on top of the general content API to handle device-specific needs. I
think
this is a sound strategy, as it contains the volatility in a separate
layer
while ensuring that everything is ultimately consuming the
general-purpose
API. If the need for app-specific massaging disappears over time, we
can
simply shut down the custom service / API end point without affecting
the
general API.
I can definitely understand that motivation for providing mobile
specific
service layer - so if the services team wants to implement the API in
this
way and support that architecture, I am totally on board.
My remaining hesitation here is that from the reading of this proposal,
the
mobile team is the owner of implementing this service, not the services team (Maybe I am misreading?).
This leads me to ask questions like: Why is the mobile apps team investigating which is the best server side technology? That seems outside of our domain knowledge. Who will be responsible for maintaining this code? Who will be testing it to make sure that is performant?
I'm new, so maybe these answers are obvious to others, but to me they
seem
fuzzy when responsibilities are divided between two teams.
I would propose that this be a project that the Services Team owns. And that the Mobile Apps Team defines specs on what they need the new
service
to provide. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
