Linux Cluster
Topic starter 14/07/2025 7:37 am
A Linux cluster is a group of interconnected Linux-based computers (nodes) that work together as a single system to provide increased performance, availability, and scalability. These clusters are often used for high-performance computing, data analysis, or situations where a single computer cannot handle the workload.

Key Concepts:
Nodes:
Individual computers within the cluster, each running the Linux operating system.
Interconnected:
Nodes are connected via a network, allowing them to communicate and share resources.
Shared Resources:
Nodes can share resources like storage, processing power, and memory to tackle complex tasks or provide high availability for services.
Single System Image:
From a user's perspective, the cluster appears as a single, powerful computer, even though it's composed of multiple machines.

Types of Clusters:
High Availability (HA) Clusters:
Designed to ensure continuous service even if one or more nodes fail. They achieve this through automatic failover mechanisms, where services are quickly transferred to a working node.
Load Balancing Clusters:
Distribute incoming traffic across multiple nodes to prevent any single node from being overwhelmed.
High-Performance Computing (HPC) Clusters:
Combine the processing power of multiple nodes to solve computationally intensive problems.
Shared Storage Clusters:
Utilize shared storage (like a SAN) to ensure data consistency and accessibility across all nodes
