Why the Linux OOM Killer Terminates Your C++ Processes on Linode (And How to Prevent It)

Understanding the Linux OOM Killer The Out-Of-Memory (OOM) Killer is a crucial component of the Linux kernel designed to prevent a system from crashing entirely when it runs out of available memory. When the system reaches a critical memory exhaustion point, the OOM Killer is invoked to reclaim memory by terminating one or more processes. […]

Disaster Recovery 101: Architecting Auto-Failovers for Elasticsearch and Ruby Deployments on Linode

Elasticsearch Cluster Setup for High Availability Achieving automated failover for Elasticsearch hinges on a robust, multi-node cluster configuration. We’ll focus on a setup designed for resilience, leveraging Elasticsearch’s built-in master election and shard replication mechanisms. For this example, we’ll assume a Linode environment with three dedicated Elasticsearch nodes, each running Ubuntu 22.04 LTS. The core […]
