What Is a Linux Server? Everything You Need to Know (2026)

An open-source foundation for resilient infrastructure: on-prem, cloud, and hybrid. IT downtime costs organizations an average of $9,000 per minute, or more than $1 million per hour. That’s real money lost when websites crash, transactions fail, or internal systems go offline. For many organizations, avoiding those losses starts with choosing the right server operating system (OS). Why? The OS sets the foundation for how stable, secure, and cost-efficient your infrastructure will be.

Introducing Application Metrics: Track the signal, see the spike, jump to the trace

A few weeks ago we had a bug with Session Replay. Replays were failing in some browsers once more than 1,000 video segments loaded. We had no idea how often it happened or who was hitting it, and because the failure didn’t always produce an error, we had no way to find affected users to reproduce it. Before, we could’ve answered this with spans or logs, but it’s clunky — spans are often sampled, so you can miss outliers; logs are less structured and tend to change over time.

ActiveMQ JMS 2.0 Implementation Guide: Simplified API, Transactions & Spring

For most of JMS's lifetime, writing a simple producer required creating a ConnectionFactory, creating a Connection, starting it, creating a Session, creating a MessageProducer, creating a Message, calling send(), and then closing the producer, session, and connection with the close calls safely wrapped in finally blocks to prevent resource leaks. Every developer knew the pattern. Every developer wrote it slightly differently. Every code review had the same comments about resource management.

Introducing the Coralogix CLI: Headless Observability for Every Agent

This article is a high-level overview of the Coralogix CLI. For a deeper look at how it works in practice, read the full technical deep dive here. Agent-driven investigation sounds simple: read the alert, query the data, return the cause. In reality, most agents either overload their context window with raw logs or guess at queries and return incorrect results.

SmartAssist and SQL Analytics - AI-powered querying

SQL Analytics has always been one of my favourite SquaredUp features. That's not just because I can use raw SQL to achieve complex data transformations. The fact that I can run SQL queries over data from all sorts of sources — not just relational databases, gives incredible power and flexibility. The great news is that SQL Analytics now ships with our AI-driven SmartAssist technology.

The World Beneath The Dashboards

Most people assume the modern enterprise runs cleanly on the dashboards and cloud consoles that dominate today’s digital workspaces. Anyone who operates these environments understands a more complicated truth. The real work happens beneath those surfaces, in systems few people notice until something slips. Across industries, engineers face the same recurring scenario: a routine shift disrupted by signals of degradation somewhere in the environment.

Moving Beyond SolarWinds: A Guide to Modern Observability

Industry-leading observability experts provide strategic guidance on why and how modern IT teams are successfully moving beyond SolarWinds to more resilient, cloud-native platforms. IT teams running SolarWinds often know the pain points well before they start evaluating alternatives: separate modules for different monitoring needs, a self-hosted deployment model that requires ongoing maintenance, and pricing that gets harder to predict after each acquisition.

How to Monitor Your Node.js App on Hetzner with AppSignal

More and more developers are choosing self-hosting over traditional PaaS. At first, self-hosting may seem like unnecessary heavy lifting, especially when you can deploy as fast as creating a repo. However, with correct tooling, it’s easy to see why devs are moving away from PaaS. You get dedicated resources and (if needed) a European data center at a fraction of the cost.
