Then, the data needs to be shipped to Logstash, stored and aggregated in Elasticsearch, and then turned into Kibana graphs.

Which is better splunk or elk?

Both solutions are relatively easy to deploy and use, especially considering each respective platform's breadth of features and capabilities. That said, Splunk's dashboards offer more accessible features and its configuration options are a bit more refined and intuitive than ELK/Elastic Stack's.

Is ELK Stack a SIEM?

So, can the ELK Stack be used for SIEM? The answer to this question is simple. In its raw form, consisting of Logstash, Elasticsearch, Kibana, and Beats — the ELK Stack is NOT a SIEM solution. While an extremely powerful tool for centralized logging, the ELK Stack cannot be used as-is for SIEM.

Is Elk similar to Splunk?

Both Splunk and ELK include a dashboard-type interface with visualizations of aggregated data. The Splunk interface is a web-based user interface that allows users to add and edit dashboard components. Each user has access to a different customizable dashboard.

How many containers a pod can run?

Remember that every container in a pod runs on the same node, and you can't independently stop or restart containers; usual best practice is to run one container in a pod, with additional containers only for things like an Istio network-proxy sidecar.
