AWS Application Auto Scaling
AWS Application Auto Scaling is a service that automatically adjusts the capacity of scalable resources in AWS to maintain steady, predictable performance at the lowest possible cost. It works with various AWS services like EC2, ECS, DynamoDB, and Aurora to scale resources based on predefined policies or schedules. This helps applications handle varying loads efficiently without manual intervention.
Developers should use AWS Application Auto Scaling when building applications on AWS that experience fluctuating traffic, such as web apps, APIs, or data processing systems, to ensure high availability and cost optimization. It's particularly useful for handling traffic spikes, seasonal demand, or unpredictable workloads, as it automatically scales resources up during peak times and down during lulls, reducing operational overhead.
