The Definition of the “Application” Has Changed

A single transaction now traverses services, Kubernetes, infrastructure, storage, networks, and increasingly AI-driven workloads — all operating together as a distributed system.

When performance drops, most teams can prove the app is slow. What they can’t prove is why.

This eBook explores:

• Why the traditional definition of “the application” no longer holds
• How hybrid and AI-driven systems blur ownership boundaries
• Why legacy APM creates debate instead of clarity
• What modern application observability must include to establish cause, not just symptoms
• Why breadth and depth are prerequisites for safe, effective Agentic AI

If your teams are stuck defending code during infrastructure-driven incidents or preparing for agent-driven operations, this guide reframes the problem.
