A proof of concept (PoC) is a way to demonstrate that a new cloud feature is feasible and works as intended. A PoC is usually limited to the technical requirements of the feature and does not involve the user interface or user feedback. A PoC is used to show the customer the working result of the new cloud feature and to convince them to adopt the solution12. A PoC is different from a benchmark, which is a measure of the performance or quality of a system or product. A PoC is also different from a baseline, which is a reference point or standard for comparison. A PoC is also different from a feasibility study, which is an analysis of the viability and benefits of a project or idea3.
