Understanding Auto Scaling: A Key Concept in Cloud Computing

Auto scaling is a critical feature in cloud computing that automatically adjusts the number of compute resources (such as servers or instances) based on current demand. When traffic spikes, the system adds more resources to handle the load; when demand drops, it removes excess resources to save costs. This ensures applications remain available and responsive without manual intervention. Auto scaling is widely used in platforms like AWS, Azure, and Google Cloud to optimize performance and cost efficiency.
