- Core competencies are the main strengths or strategic advantages of a business that include pooled knowledge and technical capacities that allow a business to be competitive. They should provide potential access to markets and make a significant contribution to customer benefits. They are also difficult for competitors to imitate. - Amazon's core competency is its cloud computing service AWS, which provides visibility and control of infrastructure through a unified interface. It allows viewing optional data from various AWS resources and grouping them for monitoring, troubleshooting, and controlling groups of resources. AWS also enables quick detection and resolution of problems through easy-to-use automation.
