Elastic Observability 8.2: Tail-based sampling, plus more serverless visibility for AWS

Elastic Observability 8.2 introduces advanced features aimed at enhancing visibility and efficiency in cloud-native environments, with key updates including tail-based sampling for distributed tracing and enhanced support for AWS services. Tail-based sampling allows for more strategic data collection by deciding which transactions to sample after completion, offering granular control to capture significant transactions based on criteria like duration and outcome. Additionally, the release improves serverless visibility by enabling the collection of traces from AWS Lambda functions and simplifies data ingestion from various AWS sources, enhancing overall observability. The update also introduces new synthetic testing infrastructure in beta and supports compressed spans to optimize network transfer and storage costs for data-intensive applications. These advancements are designed to help DevOps and SRE teams eliminate blind spots, reduce total ownership costs, and accelerate troubleshooting in complex, high-volume distributed systems, while continuing to enhance alerting and management capabilities.
