Application platforms provide runtime environments for application logic. They manage the life cycle of an application or application component, and ensure the availability, reliability, scalability, security and monitoring of application logic. They typically support distributed application deployments across multiple nodes. Some also support cloud-style operations (elasticity, multitenancy and self-service).
Gartner defines business process automation (BPA) tools as software that enables the design, execution and monitoring of business processes involving diverse sets of systems and humans. BPA tools provide an environment for developing, running and monitoring business processes that incorporate process models (and other business, decision and data models) enabling automation of business operations. BPA tools play a crucial role in streamlining business processes, thereby increasing efficiency, reducing human error and enabling better decision making across various functions and industries.
