Is Autoscaling Elasticsearch horizontally or vertically possible?

Is there a way to AUTO-scaling elasticsearch nodes horizantally or vertically on premises or on cloud without losing data especially in SOC usage ?

please suggest

Yes, Elasticsearch supports Autoscaling.

On-cloud, https://cloud.elastic.co/, check Deployment autoscaling | Elasticsearch Service Documentation | Elastic.

On-premise, check Autoscaling | Elasticsearch Guide [8.15] | Elastic.

If you deploy on k8s, check Elasticsearch autoscaling | Elastic Cloud on Kubernetes [2.14] | Elastic.
