- Since Fleet is self-managed, some metadata is stored wherever it is deployed (e.g. Amazon, Azure, Google, your own data center, hybrid cloud, anything). That's done using a MySQL database, but the bulk of the data is not stored there — instead, it flows directly into a tool like Splunk or ElasticSearch. You can send that information to any of Fleet's supported log destinations. + Since Fleet is self-managed, some metadata is stored wherever it is deployed (e.g. Amazon, Azure, Google, your own data center, hybrid cloud, anywhere).
