The document discusses how to build trust in cloud computing. It recommends a four-layer approach: 1) Educate yourself on cloud terms and security measures; 2) Monitor cloud services and infrastructure for issues; 3) Establish processes for training, escalation, and documentation; 4) Practice failover procedures by backing up data and testing backup systems. Following these steps can help address common concerns about lack of control, visibility and reliability in cloud computing.
