The document discusses best practices for continuous delivery in financial services. It advocates for starting with the customer experience rather than the application, preventing problems before they impact customers. Gap-free data across the entire delivery chain is essential. The goal is enabling DevOps rather than just operations. Dynatrace provides unified user and application insights to help optimize spend, improve release quality, and keep up with changing customer expectations.

Remediate Fast
• Things you can’t easily diagnose with debugging tools
– New Environment / Component - Pipe Cleaning
– Race Conditions
– Intermittent Faults
– Performance issues
– You don’t have a debugger active in that environment anyway
plus you would need multiple instances
• The stuff you wish you’d logged.
