High Availability Architecture: Requirements & Best Practices

High availability in cloud computing is about ensuring that services and applications are always up and running, even if something goes wrong. This involves having backup systems, automatically switching to those backups if a problem occurs, and spreading resources across different locations to prevent downtime. High availability architecture aims to minimize downtime and ensure the system can recover quickly from failures, reducing the impact on users and the business. To achieve high availability, focus on redundancy by using backup instances for critical components, automating failover to minimize downtime, implementing load balancing to distribute traffic, spreading resources across multiple locations, and continuously monitoring system health. By doing so, you can build a reliable, highly available cloud infrastructure that minimizes downtime and provides consistent service to your users.
