The modern cloud technology stacks all support and encourage rapid prototyping and experimentation. It is no longer necessary to form committees and wrangle budgets and mission statements and navigate umpteen different sub-groups with diverse needs and concerns.
A wide range of new products and services can be rapidly prototyped and iterated over days or weeks that would have taken months or perhaps even years just five short years ago.
They key challenges no longer lie primarily in the technology execution. Diligent research and investigation can very likely turn up technology options that will readily meet your needs and goals.
The key challenges will be in matching available technology capabilities with the business problem to solve and with the internal teams and external partners that can turn an inspiring idea into profitable reality.
