Scalability — Microsoft Azure Solutions Architect (AZ-305) Practice Questions
Scalability is the ability of a system to handle increased load by adding resources, either vertically (larger SKU) or horizontally (more instances), without redesigning the architecture. In AZ-305, scalability is tested across compute (VM Scale Sets, App Service autoscale, Azure Kubernetes Service node pools), data (Cosmos DB throughput partitioning, Azure SQL elastic pools, Synapse), and networking tiers. Architects must design for both scale-out triggers based on metrics and scale-in policies to avoid over-provisioning costs. The exam often presents workloads with unpredictable or bursty traffic and asks candidates to select the combination of services and autoscale rules that meets performance SLAs while controlling spend.
