Why Do You Want to Invest in Containers?
2
What are Containers?
A package/image that can be deployed anywhere (that’s running a Linux
Kernel)
Developers create a layered image of their application that contains
everything their application requires to run on top of a base OS layer
A container image will be able to be built once and run everywhere
Developers can focus on what they do best – development - opposed to
dealing with packaging or library dependency management
Operations can deploy an entire app stack in seconds as they don’t need to
worry about prerequisites

What are Containers?
Making more efficient use of your server resources while empowering your development and operations staff
Deploying the same code to dev and prod
Easier for developers – creating a package with just the software needed to run
Can run anywhere – On Premise, Public Cloud or Private Cloud – It’s no difference!

How Do Containers Help Transform IT?
Accelerate
application
development and
delivery
Build and deliver
new cloud native
applications
Ease application
transformation
5
Without Containers
Isolated development environment
Small team builds a POC
POC hand over to Dev/Ops teams
One of the following issues is likely:
• POC doesn’t run in production/staging
• Development environment not easy to setup (different OS, different tools, missing packages)
POC can’t be safely used in production or
easily migrated to production
With Containers
Team creating POC can also deploy
POC deployed with containers
POC runs in a staging/production environment
New dev environments are easy to setup
Developers can continue using the preferred tools and OS
Happy Developers! Productive teams!

Deploying Microservices
Microservices help companies move faster. Containers make it work!
Without Containers
• Set up development environments
• Download, Run all services locally
• (Try to) keep all services up to date
• Check code against dependencies
• Submission of code becomes difficult
With Containers
• Containers are great for
Microservices
• Setup a development namespace
• Developers push code into
dedicated containers -> saves lot of
time
• No need to keep code locally
• Continuous Integration/Continuous
Development (CI/CD) run against all
services

Why a Container Management Platform?

Total Cost Of Ownership is Compelling
The Business Case Works
“The reduction in duplication doesn't just free up
resources on the server, it frees up other
resources too. This is among the primary
drivers of containers in enterprise IT—to
reduce overhead and boost efficiency.”
Containers: Economically, they appear
to be a better option than hardware
virtualization. 451 Research.

What is SUSE CaaS Platform?
Speed application delivery to improve business agility
SUSE CaaS Platform is an enterprise class
container management solution that
enables IT and DevOps professionals to more
easily deploy, manage, and scale container-
based applications and services.

Three Key Technology Components
23
SUSE MicroOS for Hosting Containers
A purpose built operating system designed for running containers and
optimized for large deployments..
Contains everything you need for running containers in production
Key features include:
• An easy to manage/upgrade OS
• Easily setup/manage a cluster of nodes
• Use core SUSE Linux technologies,
such as btrfs, RPM, autoyast
• Scalable - up to thousands of nodes
• Transactional/Atomic updates
24
Kubernetes for Container Orchestration
Helps you deploy and run large numbers of containers at scale in a production
ready environment
Deploy
Manage
Scale
Clustered
Allows users to manage applications, not machines
• Complete container orchestration solution
• Open source
• Production grade
• Industry-leading container technology
• Designed by Google, now part of Cloud
Native Computing Foundation
25
Kubernetes Deployment is Not Easy
Kubernetes is great for container orchestration but is
notoriously hard to
• Set up/install
• Configure
• Update
• Manage
• Secure
SUSE CaaS Platform takes this pain away
What used to take hours for skilled engineers can be
done in minutes by junior administrators

HelmPackage management for Kubernetes
What is Helm? • Tool to manage Kubernetes application
• Streamlines installation and management
• It’s like ‘zypper’ for Kubernetes
• Helm has two parts: a client (helm) and a server (tiller).
• Tiller runs inside of Kubernetes cluster, and manages
releases (installations) of charts*
• During SUSE CaaS Platform set up the server can be
installed on the Kubernetes cluster and then Helm can be
used to deploy containerized applications.
Why Helm? • Ability to deploy applications from SUSE maintained Helm
charts or from 3rd party sources
• Official tool to deploy containerized products such as SUSE
Cloud Application Platform
• Easy to integrate with SUSE CaaS Platform* “Helm Chart” is the Kubernetes equivalent of an RPM file
