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!

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.

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

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
