- 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** |
**Category** | **Requirement** | **Benefit** | **Acceptance Criteria** |
**Priority** |
|---------------------------|-----------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------|--------------|
| **Centralized Edge Management** | PCCP Core Control Plane (Morpheus) must
manage all customer PC Edge sites. | Simplifies managing edge sites from a
single control plane. | PCCP reflects edge site inventory, monitors connectivity
status, and allows provisioning and updates. | High | | | Support hierarchical
management views in GreenLake’s Central Service. | Organizes edge sites by
regions, tenants, or business units. | Central Service UI provides hierarchical
views of edge sites and associated resources. | Medium | | **Local Worker
Nodes** | Deploy a small worker node instance at each edge site to execute local
tasks. | Ensures edge systems operate autonomously during outages. | Worker node
successfully executes local tasks independently of the central control plane. |
High | | | Facilitate connectivity between edge sites and datacenter control
plane instances. | Maintains secure communication and integration with PCCP. |
Worker nodes automatically establish and manage VPN/RDA tunnels for reliable
connectivity. | High | | | Worker nodes must maintain their own state for
critical resource management. | Improves edge system reliability and resilience.
| Worker nodes retain state information after reboots or connectivity
interruptions. | High | | **Lifecycle Management** | Provision compute resources
via GUI, API, and Terraform provider. | Enables flexible and user-friendly
resource management. | Compute resources (VMs, bare metal nodes) are
provisioned, monitored, and updated via GUI, API, Terraform. | High | | |
Provision network resources via GUI, API, and Terraform provider. | Simplifies
network configuration for edge systems. | Network resources (e.g., VLANs, VPN
tunnels) are provisioned and managed via GUI, API, Terraform. | High | | |
Provision storage resources via GUI, API, and Terraform provider. | Enhances
storage lifecycle management for edge workloads. | Storage resources (e.g.,
volumes, file shares) are provisioned and updated via GUI, API, Terraform. |
High | | | Provide lifecycle management workflows for compute, network, and
storage updates. | Simplifies resource upgrades and patching processes. |
Updates are applied successfully to edge resources, with rollback options
available in case of failures. | High | | **Secure Communication** | Establish
encrypted VPN tunnels between edge sites and the central control plane. |
Protects data in transit across multi-hop network architectures. | VPN tunnels
are encrypted with AES-256 and self-routed for multi-hop scenarios. | High | | |
Implement RDA tunneling as an alternative secure communication method. |
Addresses use cases where RDA is preferred over VPN. | RDA tunnels are
operational with encryption and performance comparable to VPN tunnels. | Medium
| | **Compliance** | Enable compliance with ISO 27001 standards through
configurable blueprints. | Ensures edge systems meet industry-standard security
requirements.| ISO 27001 compliance blueprints are created, validated, and
applied to edge systems. | Medium | | | Enable compliance with GDPR standards
through configurable blueprints. | Ensures edge systems adhere to data privacy
regulations. | GDPR compliance blueprints are created, validated, and applied to
edge systems. | Medium | | **Monitoring and Instrumentation** | Collect metrics
and logs from edge systems for centralized monitoring. | Improves visibility
into system performance and health. | Metrics (e.g., CPU/memory usage,
filesystem space) and logs are sent to GreenLake Central Service. | High | | |
Implement predictive analytics for resource usage and upgrade requirements. |
Proactively identifies capacity or performance bottlenecks. | Central Service
displays resource usage trends and upgrade recommendations. | Medium | | **High
Availability** | Support high availability for edge worker nodes in both virtual
