- 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** |
