The edge layer which this blueprint targets is the Telco Edge. 

Below are the high-level features which this blueprint will go on to implement in phase-wise.

• Lightweight MEP Solution
• Autonomous MEP Edge Sites. 
• Unified Portal for platform management and for App developers.
• Sandbox with SDKs and tools chains for MEC app developers
• Heterogeneous deployment on Multi-Arch. 
• ETSI MEC Compliant Compliant.

Use Case

Lightweight MEC platform, enable real-time enterprise applications on 5G telco edge.

...

Diverse types of applications in various sectors, not limited to below:
● Gaming Applications, VR Live broadcasting
● Industrial The industrial park, Campus office etc.
● Video Orchestration and Optimization
● Latency Senstive Sensitive Application for Enterprise scenarios Etc

...

Use Case 3

Business Drivers

The EALT EALTEdge Blueprint is for the Telco Edge, it targets the telecom operators to leverage this blueprint platform services and provide value added service, in return for better revenue generation. It also provide an Application Development Ecosystem by providing open SDK to developer community to develop application which can be tested and deployed easily on the MEP sites. 

...

The Enterprise Applications on Lightweight 5G Telco Edge platform architecture consists of a MECM (Controller) Cluster  (Cloud) and single to multiple MEP Edge MEC Host  Sites .

The MECM Cluster is a Central Cloud Server which controls the deployment of applications on MEP SitesMEC Hosts.  The MECM node can be a single node or a multiple node K8S Cluster.

MECM Components:

• User Management Portal
• Application Management 
• Dashboard for Monitoring MEP Sites.
• Workflow
• IAAS Adapter
• Policy
• FCAPS
• Host Selection

MECM: 

MEC Manager is the central entity in the MEC system responsible for application and service deployment in an highly distributed computing environment, it provides overall view of hosts and applications deployed in the hosts. MEC Manager is the central entity in the MEC system responsible for application and service deployment in an highly distributed computing
environment, it provides overall view of hosts and applications deployed in the hosts.
MECM comprises of MEP manager which performs the following tasks
➢ Application Package Management: On-boarding of application packages and if necessary adjusting them to comply with operator policies, keeping a record of on-boarded packages
➢ Applicatin LCM: Selecting appropriate MEC host(s) for application instantiation based on user inputs, keeping record of instantiated applications on specified hosts. Also carries out other LCM operations like query, deletion, termination etc.

MEC Host:

The MEC Host The MEP Sites are the components where the real action takes place. MEP MEC Host components manages  the execution of various Telco Edge Applications, it provides various services which can be leveraged by edge applications for smooth functioning and its planned to provide additional aPaas services like Machine Vision, Video Analytics , IoT Analytics etc in future releases. The MEP sites will be a single node  or a multiple node K3S Cluster, on which applications will be deployed the MECM Application Management module. The MEP MEC Host will be hosted on a light weight OS.

MEP Components:

• MEP Services – Location , RNI , Bandwidth , DNS. 
• Event BUS
• Service Registry
• Monitoring

API: EALTEdge Blurprint provides ETSI compliance interfaces specified below for mentioned functionalities:

• MP1 : It is a interfaces between applications and MEP for Service Registry , Discovery and Service Availability Notification.
• MM3: It is a interface between Mobile Edge Orchestrator and the Mobile Edge Platform Manager is used for the management of the application lifecycle and keeping track of available mobile edge services.

Platform Architecture

The below diagram gives a overall architecture of the Enterprise Application on Lightweight 5G Telco Edge blueprint which will be finally commissionedas given in Release 3. 

In the current release the  components released are 

In MECM :

• Dashboard
• APP Mgmt
• Common DB

In MEP :

• Monitoring
• Service Registry
• Event Bus
• CNI
• Lightweight Kubernetes EcoSystem.

Note: EALTEdge Blueprint Deployment has been tested on Cloud VM and is not tested on Bare-Metal Environment. Though, theoretically deployment should work in bare metal,  provided hardware and software prerequisites are met. Kindly refer R3 - Test Documentation of Enterprise Applications on Lightweight 5G Telco Edge (EALTEdge) to get details on the tested deployment.

MECM Components:

• Application LCM: Handles the application life cycle management of Applications. 
• Catalog: Provides application package management
• Monitoring: Monitoring and Visualisation of platform and applications.
• Common DB: Persistent Database.

MEC  Host Components:

• MEP Agent: Client Libraries for application developer for service registry and discovery.
• API Gateway: Single entry point for MEP Services.
• Certificate Management: Cloud Native Certificate Creation and Management.
• Secret Management: Cloud Native Secret Generation and Management.
• Event BUS: Message BUS Service offered to applications.
• CNI: Container Network.
• Service Registry: The service registry provides visibility of the services available on the MEC server.
• Monitoring: Monitoring and Visualisation of platform and applications.
• Common DB: Persistent Database.

Software Platform Architecture

EALT EALTEdge Software Components 

Unified CLI: Command Line Interface provides the user interface to install the EALT EALTEdge environment.

MEPM: 

• APPLCM: Handles the application life cycle management including Application Creation, Instantiation, Termination, Deletion, Query etc. on one or multiple MEC Hosts. 
• Catalog: Provides application package management including Application package Upload, Query, Deletion, etc. 

MEP:MECM Module to deploy applications on MEP Cluster.

• Service Registry : The service registry provides visibility of the services available on the MEC server. It uses the concept of loose coupling of services, providing flexibility in application deployment. In addition, the service registry presents service availability (status of the service) together with the related interfaces and versions. It is used by applications to discover and locate the end-points for the services they require, and to publish their own service end-point for other applications to use. The access to the service registry is controlled (authenticated and
