OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. Here are some of the core services provided by OpenStack:

1. **Nova (Compute Service)**: This is the primary computing engine behind OpenStack. It is used for deploying and managing large numbers of virtual machines and other instances to handle computing tasks.

2. **Swift (Object Storage Service)**: Swift is a storage system for objects and files. Rather than the traditional approach of referring to files by their disk location, developers can instead refer to a unique identifier referring to the file or piece of information and let OpenStack decide where to store this information.

3. **Cinder (Block Storage Service)**: Cinder is a block storage component, which is more analogous to the traditional notion of a computer being able to access specific locations on a disk drive. This is often used for access to files at a low level than the file system itself, and is often used by databases.

4. **Neutron (Networking Service)**: This provides the networking capability for OpenStack. It ensures that each of the components of an OpenStack deployment can communicate with one another quickly and efficiently.

5. **Horizon (Dashboard)**: This is the dashboard behind OpenStack. It is the only graphical interface to OpenStack, so for users wanting to give OpenStack a try, this may be the first component they actually “see.”

6. **Keystone (Identity Service)**: This provides identity services for OpenStack. It is essentially a central list of all of the users of the OpenStack cloud, mapped against all of the services provided by the cloud which they have permission to use. It provides multiple means of access, meaning developers can easily map their existing user access methods against Keystone.

7. **Glance (Image Service)**: This provides image services to OpenStack. In this case, “images” refers to images (or virtual copies) of hard disks. Glance allows these images to be used as templates when deploying new virtual machine instances.

8. **Heat (Orchestration Service)**: This is a service to orchestrate multiple composite cloud applications using templates, through both an OpenStack-native REST API and a CloudFormation-compatible Query API.

9. **Ceilometer (Telemetry Service)**: This provides telemetry services, which allow the cloud to provide billing services to individual users of the cloud. It also keeps a verifiable count of each user’s system usage of each of the various components of an OpenStack cloud.

10. **Trove (Database Service)**: This provides scalable and reliable Cloud Database as a Service functionality for both relational and non-relational database engines.

These are the core services provided by OpenStack. However, there are many other components that can be added to an OpenStack deployment to provide additional functionality.
