Machine learning workloads demand a different infrastructure profile than general-purpose IT. Training, inference, and data preprocessing each stress compute, memory, storage, and network in distinct ways. Here’s how to build and tune a stack that keeps GPUs fed without wasting budget. 1. Assess Workload Requirements Identify the workload mix: training (high GPU, high bandwidth), inference […]
Resolving “Out of Memory” (OOM) killer events on Linux servers requires a systematic approach to identify the cause and implement appropriate solutions. Here are the steps and strategies to address OOM issues: 1. Analyze Logs and Identify the Cause Check System Logs: Examine the /var/log/messages or /var/log/syslog file for OOM-related entries. Search for “oom-killer” or […]
Long-term data archival demands a strategy that covers integrity, security, accessibility, and compliance. Here’s how to build one. 1. Assess Your Archival Needs Data type: determine what you’re archiving (compliance records, logs, historical data, media files). Retention period: define how long each category must be kept based on legal, regulatory, or business requirements. Access frequency: […]
Backing up and restoring Kubernetes clusters is necessary to maintain the availability and integrity of your applications and data. This article covers the key components to back up, tools you can use, and the steps to perform backup and restore operations. Key Components to Back Up etcd Database — Stores the cluster state, including secrets, […]
Backing up and restoring Kubernetes configurations is a critical task for business continuity and disaster recovery. Backup Kubernetes Configurations Kubernetes configurations are primarily stored in etcd, the key-value store that Kubernetes uses as its backing store. You should also back up application manifests, custom resource definitions (CRDs), and other cluster-level configurations. 1. Backup etcd Data […]
Just-In-Time (JIT) access reduces the attack surface by granting privileged access only when needed, for a limited time. Here’s how to implement it for critical infrastructure. 1. Define Scope and Objectives Identify Critical Systems: Pinpoint the systems requiring JIT access (servers, storage, virtualization platforms, Kubernetes clusters, network devices). Define Use Cases: Determine scenarios where JIT […]
