This document discusses DevOps practices and container technologies like Docker and Kubernetes. It provides an overview of containers as an application delivery mechanism and how Docker and Kubernetes can be used to deploy and manage containerized applications at scale. It also summarizes key benefits of containers like speed, efficiency, and portability as well as how Docker and Kubernetes address challenges like application deployment, scaling, networking, and reliability.

7. Agenda

9. developers
I need to create applications
at a competitive rate without
worrying about IT
New applications run smoothly
on my machine but malfunction
on traditional IT servers
My productivity and application
innovation become suspended
when I have to wait on IT

10. IT
I need to manage servers
and maintain compliance
with little disruption
I’m unsure of how to integrate
unfamiliar applications, and I
require help from developers
I’m unable to focus on both
server protection and
application compliance

14. DevOps is the union of
people, process, and
products to enable
continuous delivery of
value to our end users.

18. Recap

19. Developers
Enable ‘write-once, run-anywhere’ apps
Enables microservice architectures
Great for dev/test of apps and services
Production realism
Growing Developer Community
Operations
Portability, Portability, Portability
Standardized development, QA, and prod
environments
Abstract differences in OS distributions
and underlying infrastructure
Higher compute density
Easily scale-up and scale-down in response
to changing business needs

20. container
Containers = operating system virtualization Traditional virtual machines = hardware virtualization
Windows Server containers: maximum speed and density Hyper-V containers: isolation plus performance

21. container
Not a real thing. An application delivery mechanism with
process isolation based on several Linux kernel features.
(what a process can see) (what a process can use)

22. What is ?
• An open source container runtime
• Mac, Windows & Linux support
• Command line tool
• “Dockerfile” file format for building container
images
• The Docker image format with layered filesystem

30. Kubernetes
Portable
Public, private, hybrid,
multi-cloud
Extensible
Modular, pluggable,
hookable, composable
Self-healing
Auto-placement, auto-restart,
auto-replication, auto-scaling

31. Kubernetes
Deploy your
applications quickly
and predictably
Scale your
applications on
the fly
Roll out
new features
seamlessly
Limit hardware
usage to required
resources only

41. Azure Container Service
(AKS)

43. Why AKS?

50. The best way to find, share, and use software
built for Kubernetes
Manage complexity
Charts can describe complex
apps; provide repeatable
app installs, and serve as a
single point of authority
Easy updates
Take the pain out
of updates with in-
place upgrades and
custom hooks
Simple sharing
Charts are easy to
version, share, and host
on public or private
servers
Rollbacks
Use helm rollback
to roll back to an older
version of a release
with ease
