OpenStack is a cloud-computing software platform that can be likened to Amazon Web Services but can be hosted anywhere. Developed by Rackspace and NASA, it has gained high-profile supporters like Google, Hewlett-Packard, IBM, and Intel. The platform features a modular architecture with 16 services, including OpenStack meta-services. Datadog's integration provides visibility into Nova, the computing controller, and Neutron, the network management module, offering metrics on workload, virtual machines, hypervisor metrics, project/tenant information, host-level performance statistics, and more. The integration also includes up/down information for Keystone, an identity management and access control layer, and allows users to visualize and aggregate metrics from other systems or software in their stack, alert on abnormal behavior, detect outliers, and more.
