OpenStack Tenant Deployment Options

Deployment Option A: Operator Provides OpenStack End Point Credentials to EdgeXR

In this Deployment option, EdgeXR software is a tenant on an existing Operator OpenStack environment. EdgeXR is provided with a pool of compute resources and access to the OpenStack API endpoint. EdgeXR create cloudlets and needed platform software components using these resources and endpoint access and manage the cloudlets henceforth. EdgeXR will also manage required Firewall in OpenStack tenant level for open networks. The operator can optionally manage additional Firewall as well for restricted cases.

Neutron ML2 port security enabled
VM instance console access (VNC, SPICE, etc.)

Networking requirements

/28 External Public or External Wireless Network with a minimum of 8 IPs.
IaaS OpenStack API endpoint need to be reachable from OpenStack external/Provider networks.

Networks

External UE Wireless Network - Mandatory
External Internet Network - Optional needed only if UE Wireless Network can’t reach EdgeXR Public end points.

Image requirements

Operator can download EdgeXR Platform base image needed to create cloudlet directly during cloudlet on-boarding with EdgeXR provided Artifactory credentials on supported file formats like qcow2, vmdk, etc.
Operator need to upload EdgeXR Platform base image to OpenStack Glance first time. All subsequent base images will be loaded automatically after every EdgeXR cloudlet up-grades.

Flavor requirements

Cloudlet Management

vCPU: 2
RAM Size (MB): 4096
DISK (GB): 40

Edge application workload

Deployment Option B: Operator Onboards EdgeXR Cloudlet via EdgeXR Console

In this Deployment option, EdgeXR software will be a tenant on an existing Operator OpenStack environment Operator will access EdgeXR console, furnish cloudlet general and geographic information along with OpenStack tenant access credentials and create the cloudlets based on the instructions provided in EdgeXR console. EdgeXR will manage the cloudlets automatically henceforth. EdgeXR will also manage required Firewall in OpenStack level for open networks. Operator can optionally manage additional Firewall as well for restricted cases.
