Edge Computing along with 5G promises to revolutionize customer experience with immersive applications that we can only imagine at this point. The edge will include PNFs, VNFs, and mobile-edge applications; requiring containers, virtual machines and bare-metal compute. But while edge computing promises numerous new revenue streams, managing and orchestrating these edge infrastructure environments is not going to be a seamless, instant process. In this webinar, experts in NFV orchestration discuss the concerns you must address in the transition to the edge, and show how you can use available open source tools to create a single management environment for PNFs, VNFs, and mobile-edge applications.

Edge Computing
Edge Cloud
Cloud principles applied
at the network edge
close to the user
● Virtualization (Compute,
Storage, Networking)
● On demand
● API driven
● Automated LCM
● Commodity hardware
Convergence of IT and
telecom networking
Allows network operators to open up
their networks to new opportunities
and value chains
New, Innovative,
Immersive Applications
Opportunity for App developers to
create applications:
● Tailored to local conditions
● Provide contextualized services
● Low latency, high bandwidth
guarantees for apps

● Docker pods vs. VM pods
○ Docker pods can runs edge applications
and VNFs that are containerized
○ VM pods can run VM based VNFs and
edge applications
● Coexistence and seamless networking
with container pods and VM pods
● K8s has the CRI and we can have a k8s
CRI implementation for VM workloads
● Virtlet: one way to implement VM pods
in k8s environment
○ Virtlet is an open-source project

11. 11
What is a Virtlet?
Kubernetes CRI implementation for running VM workloads
○ Targeted at VM workloads that need to behave as containers on the outside
○ Run unmodified OpenStack VM images using qcow2 format
○ Build higher-level Kubernetes objects using VM pods
○ Use familiar kubectl pod commands to work with your VMs
○ Integrate with cluster networking using normal CNI plugins
○ Easy to deploy - only need to install simple CRI Proxy package on the nodes

12. 12
Virtlet Capabilities
● VM pods join k8s cluster network as first-class citizens
○ Pod IP is used inside the VM
○ VM pods can be targeted by k8s services like any other services
○ TCP and HTTP readiness probes supported
● Support for cloud-init
○ Can add ssh keys to VMs
○ Can add extra setup scripts
○ Mount raw devices / ephemeral volumes
○ Propagate ConfigMaps / Secrets into the VMs

13. 13
MCP Edge Networking with Virtlets
● Multiple CNI
implementations are
supported
○ Most widely used ones like
Calico, Weave and Flannel
○ Multiple CNI support using CNI
genie
(updated to support CNI spec 0.3.x)
○ SR-IOV
● Control plane and Data plane
traffic isolation
● Well suited for VNFs

14. Cloudify - The Open Edge Orchestrator
● Challenges with Edge Computing Management
● Open Edge Orchestration
● Orchestrating Multiple Environments
● Sample Use Cases

15. Edge computing
makes existing
approaches to
cloud
orchestration /
management
obsolete
Network connectivity can break, &
devices need to assume a degree
of autonomous management
Unreliable Network
Fits low-cost, small device
capacity
Minimal Footprint
Moving from thousands to
millions & billions of
managed devices
Extreme Scale
Managing devices across
multiple sites/devices
Highly Distributed

Challenges with Edge
Computing Management

16. Existing Approaches
to Network
Orchestration don’t
fit into highly
dynamic and
distributed
environment
Challenges with Edge
Computing Management
The application lifecycle and network
lifecycle doesn’t match.
Operational Challenge
Fragmented network environment with wider security
holes (open ports opened even when not needed, VPN
open permanently and not only when needed), Firewall
rules and load-balancer rules doesn’t get updated when
the application change.
Security Challenge
