Microsoft Azure Fundamentals AZ-900 Practice Question

Scalability is the ability of a system to handle increasing or decreasing workloads by automatically adding or removing resources based on demand. In Azure, scalability ensures that the application can efficiently cope with fluctuating user demand without manual configuration. High availability refers to a system's ability to remain operational and accessible despite failures, but it does not address resource adjustment for changing workloads. Fault tolerance and disaster recovery focus on maintaining service continuity during failures or disasters but are not related to automatic resource scaling.
