Alexandre Souza, a senior platform engineer at Getir, shares his expertise in managing large-scale environments and configuring requests, limits, and autoscaling.
He explores the challenges of *over-provisioning and under-provisioning* and discusses strategies for optimizing resource allocation using tools like *Horizontal Pod Autoscaler (HPA)* and *Vertical Pod Autoscaler (VPA)*.
You will learn:
- How to set appropriate *resource requests and limits* to balance application performance and cost-efficiency in large-scale Kubernetes environments.
- Strategies for implementing and configuring *Horizontal Pod Autoscaler (HPA)*, including scaling policies and behavior management.
- The differences between *CPU and memory management* in Kubernetes and their impact on workload performance.
- Techniques for leveraging tools like *KubeCost* and *StormForge* to automate resource optimization.
