Kubernetes auto-scaling comes in three layers: Horizontal Pod Autoscaler (HPA) for replica count, Vertical Pod Autoscaler (VPA) for pod resource requests, and Cluster Autoscaler for node count. You’ll typically use HPA first, add Cluster Autoscaler when nodes run out of capacity, and use VPA carefully — it restarts pods and can fight with HPA if […]
Configuring IT infrastructure for satellite communication systems requires a specialized setup to handle data transmission, processing, storage, and security. As an IT manager responsible for datacenter, storage, backup, servers, virtualization, and other components, your plan must integrate high-performance systems and ensure reliability, scalability, and redundancy. 1. Understand the Requirements Satellite Communication Needs: Determine the type […]
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 […]
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 […]
Troubleshooting application compatibility issues in a mixed infrastructure — datacenters, storage, backup, servers, virtualization, Kubernetes, GPU workloads — takes a methodical process. Here’s how to work through it. Step 1: Identify the Scope Gather the application’s documented requirements: supported OS versions, libraries, dependencies, hardware minimums. Determine whether the problem is isolated to one component (OS, […]
