Cloud Native: CNCF (2015)
•Cloud native computing uses an open source
software stack to:
– segment applications into microservices,
– package each part into its own container
– and dynamically orchestrate those containers
to optimize resource utilization

Avoid Vendor Lock-in
Open source software stack enables deployment
on any public, private cloud or hybrid cloud

8. 8
Enable Unlimited Scalability
Scales from several nodes on your laptop to tens
of thousands of self-healing multi-tenant nodes

9. 9
Increase Agility and Maintainability
By splitting applications into microservices
with explicitly described dependencies

10. 10
Achieve Resiliency
To failures of individual containers, machines, and
even data centers and to varying levels of demand

11. 11
Improve Efficiency and Resource Utilization
Via a central orchestrating process that dynamically
manages and schedules microservices

Edge?

20. 20
Edge computing is a method of optimizing cloud computing systems by
performing data processing at the edge of the
network, near the source of the data.

21. 21
The possibility of intermittent cloud connectivity is a
serious concern for mission-critical IoT applications such as a connected vehicle or other types
of autonomous systems.
…and…why Edge?
Increasing costs of shipping the large volumes of
data to the cloud for processing and storage.
Data governance and security — many organizations have sensitive data that
they don’t want to leave their premises under any circumstances.
Real-time decision making —the latencies
involved in shipping the data to the cloud for analytics
are unacceptable.
Reduce the Cost
Trust & Security
Real time, Ultra Low Latency
Offline, Independent

Kubernetes : Orchestration and Management of Edge Nodes and or workloads
Prometheus : Data Metrics and Monitoring Dashboard
Helm : Deployment Charts
Envoy: Proxy and Reverse Proxy for North-South and East-West
Core DNS : DNS resolution and management (it helps for east west or north south DNS resolution)
CNI : Workload networkings (container /pod)
gRPC: Workload messaging
NATS : Optimized Messaging service (esp for streaming data) for applications (pub/sub)
Spiffe (spire) : workload to workload identity and authentication
We can also have….cloudevents for Serverless, rook for storage, opentracing for distributed
tracing, opa for policy management..
Of course, rkt and conatinerd are part of our container runtime…
…and more based on your deployment….
