AWS offers powerful native tools alongside open-source and third-party options to provide end-to-end visibility into cloud infrastructure performance, health, and security. The AWS monitoring landscape includes services like CloudWatch, X-Ray, Amazon GuardDuty, AWS Config, Amazon Detective, Security Hub, and CloudWatch Synthetics. These tools offer features such as metrics collection, log analysis, trace visualization, security monitoring, automated response systems, and continuous improvement cycles. By adopting a layered approach to observability, including foundational services, architectural patterns, and advanced techniques like AIOps and SLOs, organizations can achieve resilience in complex AWS environments. The use of open standards like OpenTelemetry simplifies instrumentation and collection across different programming languages and cloud providers. Spacelift is an infrastructure orchestration platform that enables powerful CI/CD workflows for observability tools, while also providing drift detection and remediation capabilities.
