A software development company is designing a new cloud-native application composed of multiple independent microservices. The application needs to handle highly variable loads, including periods of inactivity, and must scale down to zero instances to optimize costs. The architecture requires robust inter-service communication, dynamic service discovery, and the ability to perform A/B testing by routing a percentage of traffic to new versions of services. The development team has strong containerization skills but prefers a platform that abstracts away the complexities of direct Kubernetes API management and underlying infrastructure operations. Which Azure container hosting and orchestration service should the company recommend to meet these requirements efficiently?

A large enterprise has deployed a critical, multi-tier application on Azure, comprising Azure Spring Apps microservices, Azure SQL Database, and several Azure Virtual Machines hosting legacy components. They are currently experiencing unexpectedly high data ingestion costs due to default monitoring configurations. The operations team requires a comprehensive monitoring solution that provides deep application performance insights, infrastructure health, and user behavior analytics, while significantly optimizing costs. The design must fulfill the following specific requirements: * Collect detailed application telemetry, including custom events and metrics, from Azure Spring Apps. * Monitor infrastructure performance counters and system logs from Azure Virtual Machines efficiently. * Implement cost-effective data retention for frequently collected logs that are less frequently queried. * Ensure critical alerts are configured to be both proactive and cost-efficient. * Provide unified dashboard visualization for all collected telemetry. Which integrated monitoring solution design best meets these requirements?

A development team manages a critical application's source code in a GitHub repository. They need to implement a robust security and compliance plan for their `main` branch to ensure code quality and prevent unauthorized changes. The organization uses Microsoft Entra ID for centralized identity management. The team has identified the following requirements: * Direct pushes to the `main` branch must be strictly prohibited. * All code changes must go through a pull request process, requiring at least two approved reviews before merging. * Automated CI build and security scanning checks must pass successfully before a pull request can be merged into `main`. * All GitHub users must authenticate via Microsoft Entra ID, and their access policies should be validated against corporate standards. Which combination of GitHub and Azure features should the team implement to meet these set of requirements?
