Apache CloudStack is an open-source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, VMware ESXi and XenServer/XCP for virtualization. Here are some of the services provided by CloudStack:

1. Infrastructure as a Service (IaaS): CloudStack provides a complete IaaS solution. It allows users to create, manage and deploy virtual machines, networks, and storage.

2. Network as a Service (NaaS): CloudStack provides a variety of networking models including Basic Networking (flat network or VLANs), Advanced Networking (VPC, Network as a Service), and Software Defined Networking (SDN).

3. Platform as a Service (PaaS): Although not a primary focus of CloudStack, it can be used to provide PaaS through integration with other tools like Kubernetes or OpenShift.

4. Storage as a Service (STaaS): CloudStack provides both primary storage for holding the running virtual machine disk images, and secondary storage for templates, ISO images and snapshots.

5. Database as a Service (DBaaS): While not a native feature, CloudStack can be integrated with other tools to provide DBaaS.

6. User Interface: CloudStack provides a user-friendly web interface for managing the cloud infrastructure. It also provides an API for programmatic access.

7. High Availability: CloudStack has built-in support for high availability of VMs. It can automatically detect and recover from VM failures.

8. Resource Accounting: CloudStack tracks resource usage for purposes of utility computing, user quotas, and reporting.

9. Multi-Tenancy: CloudStack supports multiple tenants in a single instance of the software, allowing service providers to offer public or private cloud services.

10. Scalability: CloudStack is designed to manage and monitor tens of thousands of physical servers in a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.

11. Security: CloudStack provides a robust security model, including user authentication, role-based access control, and secure API access.

12. Interoperability: CloudStack can interoperate with other cloud systems and APIs, including Amazon AWS APIs, and it supports a wide range of hypervisors and network devices.
