Introduction Today we are introducing an important enhancement to AWS Systems Manager (SSM) Documents environment variable interpolation when processing parameters. This feature, now available in schema version 2.2 with AWS Systems Manager Agent v3.3.2746.0 or later, simplifies document execution by ensuring parameter values are treated as literal strings, eliminating unexpected behavior and streamlining your automation processes. […]

Modern architectures generate vast amounts of observability data across metrics, logs, and traces. When issues arise, teams spend hours—sometimes days—manually correlating information across multiple dashboards to identify root causes, directly impacting MTTR and productivity. Amazon CloudWatch Application Signals addresses this challenge by providing deep application visibility through automatic instrumentation, capturing key metrics like latency, error […]

AWS Config tracks configuration changes across your AWS resources and AWS Organizations. AWS Config uses the configuration recorder to detect changes and records them as configuration items (CIs). As your infrastructure grows and becomes more complex, choosing the appropriate recording frequency becomes critical for maintaining operational visibility, meeting compliance requirements, and supporting your security posture. Since the launch of the periodic recording […]

Organizations leveraging AWS CloudTrail to audit API access encounter a common challenge: CloudTrail data volume grows proportionally with AWS infrastructure expansion. A multi-account AWS organization generating millions of API calls daily can quickly amass terabytes of CloudTrail logs. When security teams conduct incident investigations or account activity audits, querying these logs in Amazon Athena becomes […]

In today’s digital world, availability and reliability are crucial competitive advantages. For DevOps and SRE teams, the ability to respond quickly and effectively to incidents can mean the difference between a minor issue and a major disruption of service that impacts millions of customers. Teams must have clear-cut runbooks and appropriate observability to be ready […]

In practice: SLO monitoring with CloudWatch Application Signals In the previous post, we’ve shared the basic concepts and benefits of burn rate monitoring. In this post, we, the Amazon Product Search team, will share anecdotes from our migration from an in-house solution to CloudWatch Application Signals, and introduce how we actually implement monitoring and dashboards. […]

In theory: SLO concepts applied to Amazon Product Search In this series of posts, we will show you how we, the Amazon Product Search team, monitor key systems using Service Level Objectives (SLOs) and share our migration journey from an in-house solution to Amazon CloudWatch Application Signals. Amazon Product Search is a large distributed system […]

In today’s cloud-native world, incident response teams face overwhelming challenges. When critical applications fail, engineers must sift through mountains of observability data across multiple services; all while under intense pressure to restore service quickly. This manual correlation process is time-consuming, error-prone, and often delays resolution, resulting in extended outages and frustrated customers. Traditional monitoring tools […]

Modern distributed systems must be resilient to unexpected disruptions to maintain availability, performance, and stability. Chaos engineering helps teams uncover hidden weaknesses by deliberately injecting faults into a system and observing how it recovers. While traditional testing validates expected behavior, chaos engineering tests system resilience during failures. AWS Fault Injection Service (AWS FIS) is a […]

Introduction As the adoption of agentic AI applications continues to grow, ensuring the reliability, performance, and overall observability of these systems becomes increasingly critical. Agentic AI applications, powered by large language models (LLM) and integrated with various data sources and APIs, can quickly become complex, making it challenging to gain visibility into their inner workings […]
