PAAS FOR THE OPEN EDGE CLOUD
• Using NB PaaS APIs, Edge Cloud Services Controller provides isolation from the
underlying infrastructure as well as from virtualization, lifecycle management,
networking and connectivity platforms.
• Using PaaS APIs, the controller allows its own developers, 3rd parties and MVNOs
to create, onboard, instantiate and manage container/VM/P4-based service &
service graphs, collect analytics data, utilize provided ML libraries, and connect to
public clouds, etc.

KEY TAKEAWAYS
CORD enables telcos monetize their assets at the network edge in new ways that are in line with today’s cloud offerings.
An edge cloud platform should provide multi-tenancy in two dimensions: telco end-user subscribers and edge cloud PaaS customers.
An edge cloud is necessary to start offering delay-sensitive services to end users &
enterprises.
The edge cloud architecture needs to be inherently different than today’s cloud. It is
a distributed computing paradigm where connectivity meets the cloud.
ONF’s CORD leverages commodity hardware, disaggregation, virtualization
and programmability to provide telcos with a compelling solution.
Turk Telekom and Argela are key partners in ONF. We look forward to continued significant contributions to the platform developments from Argela and their lead in lab/field trials at Turk Telekom for M-CORD and Open Edge Cloud.
ONF’s open edge cloud aims to enable telco-offered PaaS to 3rd party application developers: Connectivity-as-a-Service, Service Mesh-as-a-Service, Telemetry-as-a-Service are example offerings.
