2. GENERAL DISTRIBUTION
The Problem
Applications require
complicated installation
and integration every time
they are deployed

3. GENERAL DISTRIBUTION
THE PROBLEM
I.T. OPERATIONSDEVELOPERS

4. GENERAL DISTRIBUTION
DEVOPS
Everything as code
Automate everything
Application is always “releaseable”
Continuous Integration/Delivery
Application monitoring
Rapid feedback
Delivery pipeline
Rebuild vs. Repair

5. GENERAL DISTRIBUTION
The Solution
Adopting a container
strategy will allow
applications to be easily
shared and deployed.

6. GENERAL DISTRIBUTION6
WHAT ARE CONTAINERS?
It Depends Who You Ask
● 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

17. GENERAL DISTRIBUTION
Scheduling
Decide where to deploy containers

WE NEED MORE THAN JUST CONTAINERS
Lifecycle and health
Keep containers running despite failures
Discovery
Find other containers on the network
Monitoring
Visibility into running containers
Security
Control who can do what
Scaling
Scale containers up and down
Persistence
Survive data beyond container lifecycle
Aggregation
Compose apps from multiple containers

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