I used Parse in South Korea to build mobile apps quickly, and the entire experience has been great. However... The latency from Parse data centers to South Korean consumers became an issue, and our users were complaining slow response time. The executive decision came when Parse was having scheduled maintenance, which took place somewhere between 11pm~5am in PST, which turned out to be our busiest time during a business day, in KST (Korea Standard Time). I had to re-build the entire infrastructure from scratch, import data from Parse, but overall it wasn't a pleasant experience. The biggest problems for me when using BaaS, was that I had no control over their business decisions, and sometimes you get screwed over and at best they can say is, "Sorry." BaaS is like the backbone to your application, if it goes down, it could mean the end for a fragile startup.
