The document discusses the Cloud Native Computing Foundation (CNCF), a non-profit organization that promotes cloud native technologies. It provides an overview of why organizations adopt cloud native approaches, including better efficiency and higher development velocity. The document also summarizes CNCF's achievements in Slovakia and outlines upcoming meetups, including topics like automation, configuration, and cloud-native storage and databases.

2. What is CNCF?
● founded in December 2015 and is a part of The Linux
Foundation.
● A non-profit foundation for getting Cloud Native:
a) open source projects
b) companies
c) enthusiasts
to come together in a neutral place.

3. Why Organizations Are Adopting Cloud Native
1. Better resource efficiency lets you to run the same
number of services on less servers
2. Cloud native infrastructure enables higher
development velocity – improving your services faster
– with lower risk
3. Cloud native allows multi-cloud (switching between
public clouds or running on multiple ones) and hybrid
cloud (moving workloads between your data center
and the public cloud)

Containers

From Virtualization to Cloud Native
•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

Network Architecture Evolution
• 1.0: Separate physical boxes for each component (e.g., routers, switches,
firewalls)

Network Architecture 1.0

16. © 2019 Cloud Native Computing Foundation16
Network Architecture Evolution
• 2.0: Physical boxes converted to virtual machines called Virtual Network
Functions (VNFs), often running on OpenStack

Network Architecture Evolution
• 3.0: Cloud-native Network Functions (CNFs) running on Kubernetes on
public, private, or hybrid clouds
