AWS Lambda Functions in Python: A Practical Guide
AWS Lambda is a serverless compute service that runs your code in response to events, without requiring you to manage any servers. Developers use it for event-driven and short-running tasks like processing file uploads, handling API requests, and running scheduled jobs. The code you deploy to Lambda is called a Lambda function, and it handles…

Auto-Generated Postmortems and RCA Summaries: How OpsAI Builds the Incident Timeline So You Don’t Have To
Post-mortems are one of the most valuable SRE practices. They are also one of the most consistently skipped. The reason is structural. Writing an accurate postmortem means reassembling an incident timeline days after it happened, from incomplete memory, scattered Slack threads, and dashboards that have already rolled over. The result is a postmortem that is…

AWS Lambda Limits: The Complete Guide to Quotas, Hard Limits, and Workarounds
AWS Lambda enforces more than a dozen limits at once. Most teams only discover the one that matters after a function fails in production. Some of these limits are hard ceilings that AWS will never raise. Others are soft quotas that scale automatically or on request. This guide covers every current Lambda quota in one…

AWS Lambda Timeout Best Practices: Causes, Limits, and Fixes
“Task timed out after 900.00 seconds.” That line in CloudWatch means your function ran out of time, and depending on where it happened, you might have a partial database write, a duplicate charge, or a customer staring at a blank screen. AWS Lambda timeouts are rarely about needing more time. Most trace back to a…

AWS Lambda CloudFormation: How to Create, Deploy, and Manage Lambda Functions
AWS Lambda runs your function code, while AWS CloudFormation defines and manages the function and its related resources, including IAM roles, triggers, and environment variables. This guide explains how to create, deploy, update, troubleshoot, and monitor a Lambda function with CloudFormation. See your Lambda functions the moment they deploy Get invocations, errors, and cold starts…

AI SRE Agent for On-Call Engineers: How OpsAI Cuts MTTR From Hours to Minutes
On-call engineering is one of the hardest knowledge-transfer problems in software, and most AI SRE agent for on-call engineers conversations start in the wrong place. A junior engineer inherits a production system at 2 AM with a P1 alert firing. They have no context for why the service behaves the way it does. Traditional runbooks…

AWS Lambda Observability With Middleware: A Setup Guide
Lambda makes shipping serverless applications fast, but troubleshooting slow executions, cold starts, or failed invocations often means switching between CloudWatch, X-Ray, and multiple monitoring tools. This guide walks you through setting up end-to-end AWS Lambda observability with Middleware from connecting your AWS account and enabling OpenTelemetry-based remote instrumentation to collecting correlated logs, metrics, and traces.…

OpsAI for Repeat Incidents: How Automated Incident Response Prevents the Same Outage Twice
Summary: Repeat incidents are not bad luck they are a failure of incident memory. Most production systems alert on symptoms, restart pods, and close tickets, but never retain the pattern so they can recognize the same failure next week. This post explains exactly how Middleware OpsAI delivers automated incident response across your full stack: using…

11 Best AI SRE Tools & Agents in 2026
AI SRE tools/agents are software systems that use large language models(LLMs) and observability data to detect anomalies, investigate root causes, and automate remediation during production incidents. SRE agents integrate with telemetry sources such as APM, logs, and infrastructure metrics to correlate signals across services. In practice, they automate work that SRE teams traditionally perform manually,…
