Ask three teams what assets exist in your environment, and you’ll get three different answers. Most organizations don’t lack tools. They lack agreement on what actually exists in their environment. Asset, endpoint and cloud data exist — but it’s fragmented, stale and trusted differently by teams across every department and function.

Somewhere out there, a domain that looks almost exactly like yours may already be registered. Maybe it swaps one letter. Maybe it uses a Cyrillic character that is visually identical to a Latin one. Maybe it just adds the word "login" or "secure" to your brand. These lookalike domains are the raw material of phishing, and most companies have no idea how many exist for their brand until something goes wrong.

ClickHouse LowCardinality cuts storage and speeds up queries on low-cardinality columns, but backfires on trace IDs. How to tell the difference. Prathamesh works as an evangelist at Last9, runs SRE stories - where SRE and DevOps folks share their stories, and maintains o11y.wiki - a glossary of all terms related to observability.

Dynamic Host Configuration Protocol (DHCP) activity changes faster than most IP inventory systems can keep up. Devices reconnect. Leases expire. Infrastructure changes constantly across servers, endpoints, and cloud environments. If your IP inventory cannot reflect those changes automatically, teams quickly lose confidence in the data they rely on to operate the network.

In recent years, the conversation about digital sovereignty has focused on data. Where it is stored, who can access it, and which laws apply when something goes wrong. Those questions still matter, but AI is forcing us to think about sovereignty in a different way.

Your Python app is throwing errors in production right now. Some of them are obvious: a 500 response, an angry Slack message from support. But most are quiet. A background task swallows an exception. A race condition surfaces only under load. A third-party API returns unexpected data and your code handles it by not handling it. If you’re relying on log files and user reports to find these, you’re debugging after the damage is done.

Learn how AWS Cloud WAN works, key benefits, limitations, use cases, and adoption best practices. As AWS environments grow across multiple regions and accounts, networking can become increasingly difficult to manage. What starts as a handful of virtual private clouds (VPCs) can quickly evolve into a complex web of connectivity, routing policies, and security requirements.

Cost monitoring, exploration, investigation, and reporting used to live in separate places, so following a single cost question meant hopping between tools.
