size JVM pods and scale them.

الموضوعات المخطط لها

• Requests are used for scheduling; limits are enforced ceilings.
• Exceeding the memory limit kills the pod (OOMKilled); set the JVM heap relative to the limit (for example -XX:MaxRAMPercentage=75); verify flags for your JDK version.
• CPU limits can throttle; many teams set CPU requests and fewer limits. Decide deliberately.
• Horizontal Pod Autoscaler (HPA) adds or removes replicas based on CPU, memory, or custom metrics.
• Rolling update settings (maxSurge, maxUnavailable) control the pace and capacity.
