In Kubernetes environments, applications often communicate with the Datadog Agent to send telemetry data such as custom metrics via DogStatsD or traces through Datadog APM. How this communication takes place depends on the communication mode set on the Datadog Cluster Agent's Admission Controller. With the sockets option, communication takes place through local inter-process communication via Unix domain sockets (UDS), whereas the service and default hostip options rely on network communication.

Developers have long used profilers to diagnose performance bottlenecks and improve the efficiency of their code. But a modern version of profiling, continuous profiling, is quietly redefining what profiling is and what it can do. By running nonstop in production with very low overhead, continuous profilers give teams always-on visibility into how their code behaves in the real world.

When organizations first begin deploying workloads on Kubernetes, it's common for them to start with a permissive egress traffic policy that allows any workload to reach the internet. This approach can make it easier for teams to stay agile and to get services up and running in fast-moving environments. But as your Kubernetes footprint grows, it's important to minimize public internet access on a per-workload basis to improve your organization's security posture.

As organizations migrate their legacy web applications from containerized or server-based deployments to serverless environments, they often run into a critical compatibility challenge. Traditional web frameworks like Flask, Express, or SpringBoot are designed to run on persistent HTTP servers, not event-driven, stateless environments like AWS Lambda. The AWS Lambda Web Adapter bridges this gap by allowing teams to run web server-based applications inside Lambda with minimal changes.

The OpenTelemetry (OTel) Collector plays a central role in collecting, processing, and exporting telemetry data. If you’re deploying the Collector in production, chances are you’ve reached for the otelcol-contrib distribution. It’s the easiest, most flexible, and most documented distribution, used in nearly every demo and getting-started guide. But here’s the catch: It’s not actually recommended for production use.

Container image layers provide valuable insight into what goes into a container, including which packages were installed, what commands were run, and where vulnerabilities might live. The metadata associated with these image layers is essential for debugging, optimizing image size, and managing security risks. However, key container-layer metadata fields such as digest, size, and created_by are sometimes missing, which can disrupt important tasks.

DASH 2025 brought the Datadog community together like never before. During our biggest event yet, thousands of attendees gathered at the North Javits Center in New York City for two and a half days of content, learning, and community, where they deepened their knowledge and connected with peers. Here's a quick look back at some of the highlights from this year's DASH.

As your application grows in complexity, identifying the root cause of issues becomes increasingly difficult. Many monitoring strategies make this even harder by siloing frontend and backend data. To effectively troubleshoot problems that spread across your app, you need visibility not just into each part of your stack, but also into how these parts interact.

As large language models (LLMs) grow more powerful, organizations are deploying agentic AI applications to tackle complex, multi-step tasks. With Amazon Bedrock Agents, developers can orchestrate these agents to manage tasks such as triggering serverless functions, calling APIs, accessing knowledge bases, and maintaining contextual conversations—all while breaking down complex user requests or tasks into manageable steps.

We are thrilled to announce that, for the fifth consecutive year, Datadog has been named a Leader in the 2025 Gartner Magic Quadrant for Observability Platforms. We believe that this recognition reflects our continued focus on helping customers observe, secure, and act on everything that matters across their technology stack.
