...
- Front End: The MECM-FE management plane mainly provides the registration of edge nodes, APPLCM, and application distribution and deployment functions from the user interface perspective, which is divided into three functional areas. Map area provides switch between nodes in different regions. The KPI, MEP capabilities and application capabilities are displayed in detail according to the currently selected node.
- AppO: Application orchestrator is the core module responsible for orchestrating life cycle maintenance operation of application. Appo orchestrates application deployment by executing specified process and automated sequence of tasks, rules and policies. Appo is responsible for retrieving the application instance information, edgeehost performance statistics and edge host platform capabilities.Rules management
- Inventory : Responsible for registrations like MEC Host, AppLCM, AppStore, application. Retrieves all the applcm records,mec host records and applications.
- APM: Application package manager responsible for application package management including Onboarding, distributing package to edge , retrieves the application package information and download the application package csar.
- Postgres DB: Open source PostgreSQL database is being used to store the information for mecm modules ie applcm details,app instance information,application data and package information.Recommended version is 12.3.

- aPaaS:
- Defect Detection Service: This is a service to detect the defect when PCB images provided
- Object Detection Service: This service can be used by developer app for various Object detection for example Bottle detection and count for Retail store inventory.
- PaaS:
- Vault: Vault is a tool for securely accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, and more. Vault provides a unified interface to any secret while providing tight access control and recording a detailed audit log.
- Cert Management: cert-manager is a native Kubernetes certificate management controller. It can help with issuing certificates from a variety of sources, such as Let’s Encrypt, HashiCorp Vault, Venafi, a simple signing key pair, or self signed. It will ensure certificates are valid and up to date, and attempt to renew certificates at a configured time before expiry.
- OpenEBS: OpenEBS is a Kubernetes native hyperconverged storage solution. OpenEBS consumes the storage (disks, SSDs, cloud volumes, etc) available on the Kubernetes worker nodes to dynamically provision Kubernetes Persistent Volumes.
OpenEBS can provision different type of Local PV for Stateful Workloads like Cassandra, MongoDB, Elastic, etc that are distributed in nature and have high availiability built into them. Depending on the type of storage attached to your Kubernetes worker nodes, you can select from Dynamic Local PV - Hostpath, Device, ZFS or Rawfile.
- Velero: Velero is an open source tool to safely backup and restore, perform disaster recovery, and migrate Kubernetes cluster resources and persistent volumes.
- Influx DB: Time series data base for user applications data.
- Prometheus Agent: cAdvisor, NodeExporter
- MEP Services:
- DNS: The MEP platform provides the domain name resolution services to the applications deployed in the EdgeGallery MEC, which can be utilized by the device applications in UE. MEC platform receives the DNS configurations from the MEC management, which includes the FQDN(Fully Qualified Domain Name), IP address and related entries. MEC applications can later query or modify the state of these configurations.
- MEP server: MEP platform services like service registry, discovery, DNS, traffic rules etc. MEP provides service registration, update, delete, and query related API interfaces. Applications can register, update, delete, and query services through LDVS-MEP. 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 authorised).MEP server: MEP platform services like service registry, discovery, DNS, traffic rules etc.Network and Rules management
- AppLCM: LCM controller and K8s plugin. Handles the application life cylce, where lcmController is mainly communicates with K8s plugin to upload config, remove config, instantiate, terminate,and query an application. It also provides APIs to query mep capabilities and kpi information from prometheus.
Below are details of Upstream and Opensource software's used in various nodes of EALTEdge Environment.
