Azure Service for Centralized Monitoring

C

The following diagram gives a high-level view of Azure Monitor. At the center of the diagram are the data stores for metrics and logs, which are the two fundamental types of data used by Azure Monitor. On the left are the sources of monitoring data that populate these data stores. On the right are the different functions that Azure Monitor performs with this collected data. This includes such actions as analysis, alerting, and streaming to external systems.

Based on the requirements provided, the best Azure service to use in this scenario is Azure Sentinel (Option A).

Azure Sentinel is a cloud-native Security Information and Event Management (SIEM) solution that provides intelligent security analytics and threat intelligence across the enterprise. It is specifically designed to address the challenges of modern-day security, such as data explosion, the increasing sophistication of attacks, and the ever-increasing number of alerts.

Azure Sentinel is an ideal solution for centralized monitoring, as it can collect log and diagnostic data from multiple sources, including third-party hosting providers and Azure subscriptions, and aggregate it into a single repository. This makes it easy to analyze data and detect potential threats across the entire environment.

Additionally, Azure Sentinel can automatically analyze log data and detect threats using a combination of machine learning algorithms and security intelligence. It can also provide automatic responses to known events, such as sending an alert or triggering an automated response.

While Azure Log Analytics (Option B), Azure Monitor (Option C), and Azure Application Insights (Option D) are all useful Azure services for monitoring and managing Azure resources, they do not provide the same level of security intelligence and threat detection as Azure Sentinel. Azure Log Analytics is a centralized logging solution that provides insights into operational data and application performance, but it does not have the same security-focused features as Azure Sentinel. Azure Monitor is a monitoring solution that provides metrics and logs for Azure resources, but it does not provide the same level of threat detection as Azure Sentinel. Azure Application Insights is an application performance management solution that helps developers detect and diagnose issues in their applications, but it is not designed for centralized monitoring and threat detection across multiple environments.

Therefore, based on the requirements provided, Azure Sentinel is the best Azure service to include in the solution.
