Scalability in a Cloud Native environment is achieved by designing applications as microservices, running them in containers and managing them through orchestration platforms such as Kubernetes. This allows individual components to scale independently based on demand. By configuring autoscaling based on CPU or memory usage, the environment automatically adapts to changing workloads. Using stateless services where possible also makes it easy to add or remove replicas. Monitoring and observability tools provide real time insights into performance, enabling timely adjustments and cost control.
