"Coding in Java, buying SAP, deploying OpenStack, and using Amazon Web Services: each one introduces a type of lock-in. Lock-in–described by Wikipedia as something that “makes a customer dependent on a vendor for products and services”–is always a hot topic of discussion in the technology community.
