How do you ensure high availability in an HLD?
Systems have high availability by using techniques like extra copies of parts, sharing workload across systems, having a contingency plan when things break, and a dispersed overall design. These methods ensure the system keeps running even when some pieces stop working properly.
Top High-Level Design(HLD) Interview Questions 2024
High-Level Design (HLD) gives a big-picture view. It shows the main parts of a system and how they fit together. HLD acts as a map, focusing on modularity, scalability, and smooth integration. The aim is clear development direction while meeting business goals and technical limits. Short sentences, longer explanations – HLD creates a balanced architectural blueprint.
