Describe how CloudWatch contributes to the creation of an observability strategy in a microservices architecture on AWS.
CloudWatch enhances observability in microservices architecture on AWS by providing comprehensive monitoring, logging, and alerting capabilities. It collects metrics from various sources like EC2 instances, Lambda functions, and custom applications, enabling users to analyze performance trends and identify bottlenecks.
Integration with other AWS services such as X-Ray and ElasticSearch allows for distributed tracing and log analysis, giving insights into service dependencies and potential issues. CloudWatch Alarms can trigger actions like auto-scaling or notifications, ensuring proactive response to anomalies.
CloudWatch Logs store application logs, while Log Insights enables querying and visualization of log data, simplifying troubleshooting. Additionally, CloudWatch Dashboards provide a customizable view of key metrics, facilitating informed decision-making.
