This domain explores how to apply this principle across critical areas, including:

• "Caching": Storing frequently accessed data closer to the application to reduce latency and improve performance.
• "Logging and Monitoring": Collecting, analyzing, and acting on telemetry data from applications and Azure resources.
• "Troubleshooting": Systematically identifying, diagnosing, and resolving issues in applications and infrastructure.
• "Performance Optimization": Improving application responsiveness, throughput, and resource efficiency.

The focus is on comprehending and applying Azure operational best practices and services to meet specific development requirements, ensuring robust and efficient application delivery.

Scenario: A company needs to optimize its critical web application for high performance and ensure it has deep visibility into its runtime behavior. They need to implement caching, centralize logs, set up alerts, and have tools for efficient troubleshooting.
