  • Tier: Tiers are logical groupings of servers that perform a similar function.
  • Nodes: Nodes are physical servers that are running one or more applications.
  • Business Transactions: Business transactions are groups of related technical transactions that represent a single business process.
  • Technical Transactions: Technical transactions are single units of work that are performed by an application.

Question 7: What is the AppDynamics infrastructure model?

Answer: The AppDynamics infrastructure model is a way of organizing and managing the infrastructure that supports the applications being monitored. It consists of the following components:

  • Clusters: Clusters are logical groupings of machines.
