Eh, regardless of how well your application is architected, it&#x27;s going to be a pain in the ass to migrate if you have a lot of data&#x2F;users&#x2F;versions of your app out in the wild.<p>If you continue to rely on BaaS providers you run the risk of playing perpetual musical chairs as each one shuts down over time. That&#x27;s not an acceptable level of risk for me, but, to each his own I guess.
