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.

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.

The agents are fast. The orchestration is chaos. You’re bouncing between terminal windows, manually rebasing branches, cleaning up messy commits, and trying to remember which agent is touching which repo.
