As someone who is non-technical, how much code/infrastructure would this save? I'm trying to understand how locked in this would really make you, and how difficult it would be to replace this on some other IaaS provider?
Any use of non-standardized service will only help you lock in further. Though a lot of companies/start-ups do not care if it saves time/cost and perhaps they are already deeply invested in the ecosystem.
It seems that this system puts together all events generated by Amazon services to trigger new events. This is usually not that complicated to code, but the catch is to make these (usually) scripts/programs highly available, which Amazon provides.
