• What & Why?
• Cloud Native Software Stacks!
• The people behind!
• How to engage/contribute?
3. Who we are
CNCF is an open source
foundation created to
We promote the use of
applications in a
architecture on any
public, private or hybrid
software developers to
build great products,
allowing businesses to
move faster than ever
4. What is cloud native …????
Cloud-native applications are
purpose built for the cloud
model. These applications—built
and deployed in a rapid cadence
by small, dedicated feature
teams to a platform that offers
easy scale-out and hardware
greater agility, resilience, and
portability across clouds. Pivotal
At the heart of "cloud-native" lie Linux,
Linux containers, and the concept of
applications assembled as microservices in
containers. Indeed, the Linux Foundation
launched the Cloud Native Computing
Foundation. But cloud-native means a lot
more than implementing Linux clusters and
running containers. It's a term that
recognizes that getting software to work in
the cloud requires a broad set of
components that work together. It also
requires an architecture that departs from
traditional enterprise application design. .
Here’s how a blog on IBM’s developer
web site distinguishes the two adjectives
Cloud-Native and Cloud-Enabled:
You can say that a cloud-enabled
application is an application that was moved
to cloud, but it was originally developed for
deployment in a traditional data center.
Some characteristics of the application had
to be changed or customized for the cloud.
On the other hand, a cloud-centric
application (also known as cloud-native and
cloud-ready) is an application that was
developed with the cloud principles of multi-
tenancy, elastic scaling and easy integration
and administration in its design.

7. 1) Kubernetes: Automating deployment, scaling, and management of containerized applications
2) Prometheus: Monitoring, metrics, alerting, visualizing, queries, integration
3) OpenTracing: Distributed tracing. Libraries available for various languages
4) Fluentd: Fluentd allows you to unify data collection and consumption for a better use and understanding of data.
5) GRPC: Define your service using Protocol Buffers, a powerful binary serialization toolset and language
6) Conainerd: An industry-standard container runtime with an emphasis on simplicity, robustness and portability.
7) Rkt: pod-native container engine for Linux. It is composable, secure, and built on standards.
8) CNI: Container Network Interface - networking for Linux containers
9) Envoy: EDGE AND SERVICE PROXY
10) Jaeger: Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber
11) Notary: A project that allows anyone to have trust over arbitrary collections of data
12) TUF: The Update Framework specification
13) Vitess: A database clustering system for horizontal scaling of MySQL
14) Linkerd: ServiceMesh - A transparent proxy that adds service discovery, routing, failure handling, and visibility
15) CoreDNS: DNS & Service Discovry - chains plugins. Each plugin performs a DNS function, such asKubernetes service
discovery, Prometheus metricsor rewriting queries.
16) Rook: File, Block, and Object Storage Services for your Cloud-Native Environments
• New proposals:
1) NATS: https://github.com/cncf/toc/pull/81
2) OPA: Consistent policy expression and enforcement mechanism and common toolset.
3) SPIFFE: Service identity (LOAS) bringing together all the pieces to recreate the environment

OCI (Open Container Initiative):
Established in June 2015 by Docker
and other leaders in the container
industry, the OCI currently contains
two specifications: the Runtime
Specification (runtime-spec) and the
Image Specification (image-spec).
The Runtime Specification outlines
how to run a “filesystem bundle”
that is unpacked on disk. At a high-
level an OCI implementation would
download an OCI Image then
unpack that image into an OCI
Runtime filesystem bundle.
Istio: An open platform to connect
Istio essentially provides developers with a
single service mesh that provides the
monitoring services to then implement the
necessary load balancing, flow-control and
security policies they need to keep their
applications running even if the network
Istio also allows developers to authenticate
and secure the communications between
different applications using a TLS
connection (which means the developer
doesn’t have to manage certificates, for
Google, IBM and Lyft launch Istio, an open-
source platform for managing and securing
Metaparticle enables you to focus on
your code, while allowing you to treat
your architecture as code as well.
Metaparticle works by defining service
patterns, which you can instantiate via
simple code. This code contains both the
definition of your architecture as well as
the implementation of the service itself.
This work was an experimental by
Brendanburns, Kuberntes Creator.
10. CNCF taking up Serverless Computing…..
CNCF created the Serverless Working Group to ‘explore the intersection of cloud native and serverless technology.’ The first
output of the group was creation of serverless landscape, which is available. https://www.cncf.io/blog/2018/02/14/cncf-takes-
19. Source Code: Git Hub
One of the prominent contributions to the open source community is in the
form of source code to existing projects.
To get start attend the SIG to start code contribution:
And so on.. For each project has its own repo, communities…..
Creating a new project
• If you have a new project to propose to CNCF please go through the
document shown in the link
• You start with proposing the project to the Technical Oversight Committee
(TOC) and based on the vote in TOC it may get accepted to the inception,
incubation or graduate stage. The process is the same for both existing
projects which seek to move into the CNCF, and new projects to be formed
within the CNCF. To graduate from inception or incubation status, the
project must meet the criteria as shown in the link
Note: To get start: Documents are an essential part of the any software
development process but most often ignored. These may include user guides,
architectures, presentations, etc.

22. Ambassador Program
• CNCF has a program called ambassadors who contribute to the CNCF projects in various ways. The Cloud Native Ambassador
program exists to empower community members with tools and resources needed to promote cloud native projects and
technology, educate a local community on the CNCF mission and contribute to CNCF projects:
