Troubleshooting DNS resolution issues is a core skill for infrastructure engineers. DNS underpins almost all network communication, so when it breaks, things stop working fast. Here’s how to isolate and fix the problem: 1. Verify the Problem Identify whether the issue affects specific systems, services, or the entire network. Try pinging the hostname (e.g., ping […]
Configuring IT infrastructure for cloud-native applications requires careful planning and implementation of modern technologies that enable scalability, flexibility, and high availability. Here are the steps you can follow to set up your IT infrastructure: 1. Assess Requirements Understand Application Needs: Identify the resource requirements (CPU, memory, GPU, storage, etc.), containerization preferences, networking needs, and dependencies. […]
1. Hardware Requirements Compute Nodes CPU: Choose servers with strong multi-core CPUs (e.g., AMD EPYC or Intel Xeon). Cassandra is CPU-intensive for queries and writes. Memory: Allocate sufficient RAM. Cassandra benefits from large amounts of memory for caching, but it doesn’t store data in memory. A good starting point is 32 GB to 64 GB […]
Storage integration makes or breaks a virtualization platform. Get it wrong and you’ll chase performance issues forever. Get it right and the infrastructure mostly runs itself. Here’s how to approach it. 1. Assess Your Storage Requirements Determine capacity based on actual VM workloads, not vendor sizing guides. Identify IOPS, throughput, and latency requirements for each […]
Troubleshooting CUDA errors on GPUs requires a systematic approach. Here’s a step-by-step guide: 1. Gather Information Before diving in, collect details about the problem: – Error Message: Note the exact CUDA error code or message (e.g., CUDA_ERROR_OUT_OF_MEMORY). – Environment: – GPU model (e.g., NVIDIA A100, RTX 3090). – CUDA version (e.g., CUDA 11.8). – Driver […]
Real-time collaboration tools — Microsoft Teams, Zoom, Slack, Google Workspace — run mostly in the vendor’s cloud. Your infrastructure job is network, identity, endpoint, and (if you self-host any components) the supporting servers and storage. Here’s the practical breakdown. 1. Assess Requirements Collaboration tools: List what you’re running (Teams, Zoom, Slack, Google Workspace, or self-hosted […]
