- Product Requirement Document: Private Cloud Control Plane - Edge (PCCP-Edge)
	  --- #### **Executive Summary** The "Private Cloud Control Plane - Edge"
	  (PCCP-Edge) is an extension of the Private Cloud Control Plane (PCCP), designed
	  to provide centralized management, secure communication, lifecycle management,
	  and compliance for distributed edge environments. Fully integrated with
	  GreenLake’s Central Service, PCCP-Edge leverages the Morpheus platform to manage
	  edge sites. Key features include autonomous edge operation, lifecycle management
	  for compute, network, and storage, secure VPN/RDA tunneling, and compliance with
	  ISO 27001 and GDPR standards. --- #### **Product Vision** PCCP-Edge extends
	  Morpheus' capabilities to manage distributed edge environments as part of a
	  unified hybrid cloud strategy. It provides seamless centralized control of edge
	  sites, secure communication with datacenter control planes, and a robust
	  platform for provisioning and managing compute, network, and storage resources.
	  PCCP-Edge aligns with HPE’s strategic direction to treat Morpheus as an
	  appliance, providing cloud-connected and disconnected deployment options. ---
- **Target Users** 1. **Infrastructure Managers**: MSP or CSP administrators
  managing edge sites from the central Private Cloud Control Plane (PCCP) via
  GreenLake Central Service. 2. **Infrastructure Consumers**: Application
  administrators, database administrators, VM administrators, and DevOps teams
  leveraging GUI, API, or Terraform to manage edge resources. 3. **Compliance
  Officers**: Professionals ensuring adherence to ISO 27001 and GDPR standards
  using pre-defined blueprints. 4. **Edge Operators**: Individuals responsible for
  maintaining local tasks and connectivity at edge sites. --- #### **Problem
  Statement** Organizations deploying workloads across distributed edge
  environments face the following challenges: - Centralized management of edge
  sites at scale while maintaining local autonomy for critical tasks. - Simplified
  lifecycle management of compute, network, and storage resources across edge and
  datacenter environments. - Secure communication across network paths in
  multi-hop architectures. - Compliance with strict industry standards such as ISO
  27001 and GDPR. - Providing a consistent user experience across GUI, API, and
  Infrastructure-as-Code (Terraform). PCCP-Edge addresses these challenges with a
  unified, secure, and scalable solution integrated with Morpheus and GreenLake.
  --- #### **Solution Overview** PCCP-Edge will: 1. **Centralized Edge
  Management**: Allow the Private Cloud Core Control Plane (Morpheus) to manage
  all customer PC Edge sites. 2. **Local Worker Nodes**: Deploy a small worker
  node instance at each edge site to execute local tasks and maintain connectivity
  to datacenter control planes. 3. **Lifecycle Management**: Provide full
  provisioning and lifecycle management of compute, network, and storage via GUI,
  API, and Terraform provider. 4. **Secure Communication**: Enable VPN and RDA
  tunneling for secure connectivity across multi-hop network architectures. 5.
  **Compliance Support**: Ensure compliance with ISO 27001 and GDPR standards via
  pre-defined blueprints (future requirement). --- ### **Requirements** |
