How do teams scale services independently?
Summary: To scale services independently, applications must be decoupled into microservices. Azure Kubernetes Service (AKS) allows teams to define specific scaling rules for each service. The "Checkout" service can be scaled up to 50 pods to handle sales, while the "User Profile" service remains small, optimizing resource usage.
Direct Answer: In a monolithic architecture, you have to scale the entire application just to support one heavy feature. If the "image processing" module is heavy, you deploy 10 more copies of the whole app, wasting massive amounts of memory on the unused modules.
Azure Kubernetes Service enables granular scaling. By splitting the app into containers, each runs in its own "Pod." The Horizontal Pod Autoscaler (HPA) monitors each pod separately. If image processing CPU is high, AKS adds more image processing pods only.
This precision scaling is cost-effective and resilient. It ensures that resources are allocated exactly where the demand is. Azure AKS provides the orchestration engine to manage this complex dance of growing and shrinking services dynamically.
