How did John address scalability challenges in the Kubernetes clusters he managed?
assistant
The client's previous setup struggled with scalability due to underutilized nodes and misconfigured autoscaling policies. John redesigned the architecture by implementing Horizontal Pod Autoscalers (HPA) and Cluster Autoscaler, which dynamically adjusted resources based on workload demands. He also optimized load balancer configurations to distribute traffic evenly, addressing bottlenecks and ensuring smooth scaling during peak usage periods. John addressed scalability challenges by implementing HPA, Cluster Autoscaler, and optimized load balancing, ensuring efficient resource allocation and seamless scaling.
