Dynamic Scaling
Dynamic scaling is a cloud computing concept that automatically adjusts the number of computing resources (such as servers, containers, or virtual machines) in response to real-time changes in workload demand. It enables systems to scale up (add resources) during peak usage and scale down (remove resources) during low usage, optimizing performance and cost-efficiency. This is typically implemented using automated policies based on metrics like CPU utilization, memory usage, or request rates.
Developers should learn dynamic scaling to build resilient and cost-effective applications in cloud environments, especially for services with variable traffic patterns like e-commerce sites, streaming platforms, or SaaS products. It ensures applications maintain performance during traffic spikes while minimizing expenses during off-peak times, reducing the need for manual intervention and over-provisioning.
