Edge Cloud Management Requirements
========================================
Edge services and deployment scenario
=========================================
+-------------------------+--------------------------+
| Edge Service | Deployment Scenario |
+-------------------------+--------------------------+
| Industrial application | On-prem |
+-------------------------+--------------------------+
| V2X | Network edge/ on-prem |
+-------------------------+--------------------------+
| AR/VR | Network edge/ on-prem |
+-------------------------+--------------------------+
| IoT analysis | on-prem |
+-------------------------+--------------------------+
| Cloud gaming | Network edge |
+-------------------------+--------------------------+
| CDN | Network edge |
+-------------------------+--------------------------+
| IoT control | On-prem/ network edge |
+-------------------------+--------------------------+
Note:
"On-prem" refers to deployment scenarios in which service being deployed in places like industrial park; “Network edge” refers to deployment scenarios in which service could be deployed in operators’ edge cloud.
Problems of providing edge cloud services
===========================================
Telco operators, also as edge cloud service providers, are facing the following problems when providing edge cloud services:
**Multiple types of cloud & remote deployment**
a) Edge resource type: VMs, containers, bare metals;
b) Widespread edge sites, hard to do deployment and installation.
**Incompatible cloud solutions from multiple cloud vendors or open source community**
a) Tens of thousands of edge sites could use IaaS from multiple vendors;
b) Different cloud solutions are incompatible to each other to some degree;
c) Inconvenient for edge cloud users if using different vendors’ edge IaaS directly.
**Lack of unified & regional-centralized operation and management**
a) Impossible to provide local O&M for each edge site (high cost, poor efficiency).
**Support both IT and CT applications**
a) Complicate for IT application to follow MANO processes;
b) Some IT applications have their own service management system;
c) Resource orchestration is enough for IT application or they don’t need to be orchestrated.
Requirements of providing edge cloud services
=================================================
**Unified management for multiple resource types**
a) Provide VM, container, bare metal resources;
b) Provide access management (connection management) and auto deployment for all edge resource pools.
**Standard resource & service interface**
a) Shield difference of multi-vendor products;
b) Provide standard and stable service, resource, APIs for edge cloud users (including end users & systems);
c) Simple deployment process for both IT & CT applications.
**Unified & Centralized O&M**
a) Centralized fcaps management;
b) Standard O&M APIs for other systems to subscribe O&M service;
c) Unified & automatic O&M entrance to provide localized O&M.
