Datadog vs Splunk
Datadog and Splunk are both data analysis platforms for infrastructure and security, but with different origins. Datadog was born in the cloud monitoring era; Splunk started as a log search and SIEM platform. Datadog wins for cloud-native application monitoring; Splunk wins for security operations (SIEM) and legacy log management at large scale.
