In Splunk Cloud, only apps that have been certified and vetted by Splunk are supported. This is because Splunk Cloud is a managed service, and Splunk ensures that all apps meet specific security, performance, and compatibility requirements before they can be installed. This certification process guarantees that the apps won't negatively impact the overall environment, ensuring a stable and secure cloud service.
Self-service installation is available, but it is limited to apps that are certified for Splunk Cloud. Non-certified apps cannot be installed directly; they require a review and approval process by Splunk support.
Splunk Cloud Reference: Refer to Splunk's documentation on app installation and the list of Cloud-vetted apps available on Splunkbase to understand which apps can be installed in Splunk Cloud.
