Increase the examination of Compliance as Code (CI/C) tools, such as Azure Policy and Open Policy Agent.

(3) IaC Toolchain Expansion

The Infrastructure as Code (IaC) toolchain has been updated to better suit actual enterprise applications:

Added in-depth examination of the Bicep template language, replacing some ARM template content.

Strengthened the application of Terraform in the Azure environment, including state management and remote execution.

Added design and implementation requirements for Azure deployment environments, supporting on-demand self-service deployment.

Expanded the coverage of configuration management tools, including Azure Automation State Configuration and Azure Machine Configuration.

(4) Deployment Strategy and Feature Management Upgrades

Added Progressive Exposure and Update Channels deployment strategies.

Strengthened the implementation and management of Feature Flags in Azure Application Configuration.

Added the integration of A/B testing in the CI/CD pipeline, supporting data-driven release decisions.

Expanded the content of database deployment automation, including schema migration and data synchronization strategies.

(5) Monitoring and Observability Improvement

Strengthened Kusto. advanced applications of Key Query Language (KQL) to support complex log analysis.

Added implementation of distributed tracing in microservice architectures, including OpenTelemetry integration.

Expanded GitHub environment monitoring, including Insights and custom chart configurations.

Added consideration of key SRE (Site Reliability Engineering) metrics, such as Service Level Objectives (SLOs) and error budgets.
