High Availability Architecture Demystified

A high available architecture is crucial for businesses that require continuous operation without failure. This system ensures optimal performance even during peak times by using multiple components, modules, or services working together. High availability clusters are a group of hosts that merge as a single system to prevent downtime and maintain continuity of service in case of failures. Load balancing plays a vital role in preventing system failures by distributing traffic across different web nodes. Active/passive and active/active clusters are two types of high availability architectures, each with its own benefits. To maximize durability and high availability, businesses need to consider load balancing, scalability, geo-redundancy, failover capabilities, Recovery Point Objective (RPO), and advanced solutions like Redis Enterprise.
