Hey Bundit, that article is a good one from a year ago. Jon has a great blog. Jon highlighted some strengths of our product and we have additionally made significant improvements over the last year. I can understand your concern about how a new product could impact your production environment, and since I don't know your production environment, allow me to respond with some information about a few customers with some serious production requirements. Facebook used Delphix to insulate their production environment from the batch jobs required for reconciling their general ledgers in the financial close process. With Delphix they went from a process that took them 21 days and still had many errors to 2 days with zero errors. As you can imagine, they generate a massive amount of data on a daily basis. Also, four of the Fortune Top 5 use us because of how we reduce the risk of issues in production. I don't know of your specific use case, but here you can find Tim Campos (CIO of Facebook) talk about Delphix.
