Universal Containers (UC) is implementing a Salesforce B2B multi-cloud project with large volumes of data and daily transactions from multiple third-party systems via multiple integrations. UC is looking at transactions of more than 1 million records a week and, in higher seasons, 10 million records a week. UC has made the decision to get a full copy sandbox to use to test all of its third-party integrations across its multiple clouds. UC has also invested in MuleSoft and the Anypoint Platform as the single enterprise service bus for all of the third-party data going into Salesforce.
