Cloud design principles focus on ensuring reliability, scalability, and recoverability to meet business needs. Below are the key aspects of effective cloud architecture.
1. Redundancy
Redundancy is a critical aspect of system design and architecture, aimed at ensuring continuity, reliability, and availability by duplicating essential components or systems.
Definition:
Redundancy refers to the duplication of critical components, systems, or data to mitigate the risk of failure. By having backups or alternative pathways, systems can continue functioning even when part of the infrastructure encounters issues.
Key Features:
- Hardware Redundancy:
Involves the duplication of physical components such as servers, storage disks, power supplies, or cooling systems. Example: A server with dual power supplies ensures operation even if one power source fails.
