What we’ll be discussing today:

AGENDA

● Who am I?○ … and why should you care?

● The official abstract for this session.○ … and how we’ll diverge from most of it.

● A grand history of software development○ It’s not like history class, I promise.

● Software development methodologies and technologies○ All the cool flashy stuff that developers use and do

● Containers○ Buckets, boxes and bins

● Orchestration○ … and I won’t even bring out my son’s trombone.

● Putting it all together○ And, if you’re good, a demo


Who the heck am I?

ABSTRACT

This session will focus on the how and why

businesses are containerizing their

applications. The portability of an application

and having the ability to move it from one cloud

to another, on premise to off, is not as difficult

as it may sound. Listen to how leveraging

container orchestration systems like

Kubernetes and Docker are giving this desired

flexibility.

modern solutions,

we need to discuss

begin with.

Where do Containers fall into all this already?

19

The ProblemApplications require complicated installation and integration every time they are deployed


20

The SolutionAdopting a container strategy allows applications to be easily and consistently shared and deployed.


Containers - An Evolution in Application Deployment

21

Enable efficiency and automation for microservices, but also supports traditional (even monolithic!) applications

Enable faster and more consistent deployments from Development to Production

Enable application portability across infrastructure footprints● Physical, Virtual, Private & Public Cloud

Containers Are Everything to Everyone

26

● Sandboxed application processes on a shared Linux OS kernel

● Simpler, lighter, and denser than virtual machines

● Portable across different environments

● Package my application and all of its dependencies

● Deploy to any environment in seconds and enable CI/CD

● Easily access and share containerized components

Great! We will use containers! Thxcya!

… But wait, there’s more.30

What about multiple coupled containers running at scale?

Containers Alone Aren’t Enough

Lifecycle and healthKeep containers running despite failures

DiscoveryFind other containers on the network

MonitoringVisibility into running containers

SecurityControl who can do what

ScalingScale containers up and down

PersistenceSurvive data beyond container lifecycle

AggregationCompose apps from multiple containers


Kubernetes to the Rescue

34

Kubernetes is an open-source system for automating deployment, operations, and scaling of containerized applications across multiple hosts.

For General AudiencesKUBERNETES

35

Kubernetes is a

cluster of simple

worker nodes

running containers

and managed by

one-or-more control

nodes.
