 <summary>What components/projects of OpenStack are you familiar with?</summary><br><b>
+I’m most familiar with several core OpenStack components:
+
+- Nova for compute resource provisioning, including VM lifecycle management.
+- Neutron for networking, focusing on creating and managing networks, subnets, and routers.
+- Cinder for block storage, used to attach and manage storage volumes.
+- Keystone for identity services, handling authentication and authorization.
+
+I’ve implemented these in past projects, configuring them for scalability and security to support multi-tenant environments.

These modules are typically used to add support for hardware devices, filesystems, or system calls. The kernel itself is monolithic, but with modules, its capabilities can be extended without having to reboot the system or recompile the entire kernel.
