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…

Trace Explorer Gets a Smarter Way to Investigate Distributed Traces
When a request fails, it rarely fails in one place. It moves through multiple layers: network, application code, and database, with each layer adding its own step to the journey. When something breaks, the hard part is finding exactly which layer, which step, and which downstream call actually caused it, not just that the request…

Application Dependency Mapping (ADM): A Practical Guide
Application dependency mapping is the process of identifying and visualizing how the services, infrastructure, and external systems that make up an application depend on one another. It shows which components a request touches, in what order, and where a failure in one component can affect others. Teams use it for incident investigation, change impact analysis…

Why Observability Migrations Fail (and What Developers Can Do About It)
Observability migrations rarely fail because the new platform is worse. They fail in the gap between the pitch deck and week three, when a missing label breaks a 2 AM alert and nobody can say whether it’s the platform or the data. This guide breaks down the five patterns that quietly sink migrations, and what…

Incident Correlation: How to Automatically Group Related Alerts From the Same Root Cause
Incident correlation automatically links alerts, logs, traces, and metrics from the same failure into one incident, instead of paging on each signal separately. This article covers how correlation works, the main grouping techniques, and how to apply them when one outage floods your on-call channel with dozens of alerts. The core trade-off is speed versus…

OpenTracing vs. OpenTelemetry: Key Differences and Migration Guide
If you searched for opentracing vs opentelemetry because your instrumentation still imports an OpenTracing library, you are looking at a dependency that CNCF archived years ago. This guide lays out what actually changed between the two projects, why the switch matters for your traces today, and a concrete path to move your services onto OpenTelemetry…

10 Best Dash0 Alternatives in 2026: Features, Pricing & OTel Support Compared
Looking for Dash0 alternatives usually means you’ve hit one of three walls: Agent0 is still in Beta, there’s no on-call or incident management built in, or you need a self-hosting path Dash0’s SaaS-only model doesn’t offer. This guide compares 10 platforms, including Middleware, Datadog, and SigNoz, across OpenTelemetry support, pricing, and free tiers, so you…

Sentry Pricing 2026: Full Cost Breakdown by Plan & Team Size
Sentry bills differently than most observability platforms: instead of metering data volume, it meters events, errors, spans, replays, logs, and attachments each with its own quota and its own overage rate. Overages on the Team plan run from $0.0003625 per error in the 50k–100k tier down to $0.0001500 per error at 20M+ events, while Business…

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…

AWS Fargate vs. Lambda: 6 Differences and How to Choose
Choosing between AWS Fargate and AWS Lambda usually comes down to one question: do you need to run a container, or just a function? Fargate runs your existing container images without you touching an EC2 instance. Lambda runs short bursts of code with no container involved at all. Match the compute to the workload and…

13 Best OpenTelemetry Tools in 2026: Ranked for DevOps and SRE Teams
Summary: OpenTelemetry tools are observability backends that ingest, store, and query telemetry data – metrics, logs, and traces – collected using the OpenTelemetry standard. OpenTelemetry (OTel) itself is a CNCF project that defines how applications emit telemetry: language SDKs for instrumentation, the OTel Collector for processing, and OTLP as the wire protocol for delivery. The…

How Middleware Turns OpenTelemetry Data Into Actionable Intelligence – Part 2
In part1, we covered how Middleware helps engineering teams new to OpenTelemetry achieve full infrastructure and application coverage in hours rather than weeks through auto-discovery, zero-code instrumentation, and UI-based collector configuration. In this blog post, I will be going to discuss about platform teams who are already using OpenTelemetry setup in their infrastructure and applications. What…
