The Kubernetes community has undergone tremendous growth over the past two years. A number of K8S use cases are currently being implemented by organizations.

1. Kubernetes Growth and
Community

Agenda
• History of Kubernetes
• Kubernetes Community Growth
• Kubernetes Use Cases

3. APPRENDA.COM
AWS is Decade Old
• Distributed, shared,
dynamic infrastructure is
“boring” (GOAL!)
• AWS valued at $168B
• Dawn of de-facto
standards for distributed
applications

4. APPRENDA.COM
Why containers?
• Performance
• Repeatability
• Isolation
• Quality of service
• Accounting
• Visibility
• Portability
A fundamentally different way
of managing applications

5. APPRENDA.COM
Now that we have containers...
Isolation: Keep jobs from interfering with each other
Scheduling: Where should my job be run?
Lifecycle: Keep my job running
Discovery: Where is my job now?
Constituency: Who is part of my job?
Scale-up: Making my jobs bigger or smaller
Auth{n,z}: Who can do things to my job?
Monitoring: What’s happening with my job?
Health: How is my job feeling?

Enter Kubernetes in 2014
• Google starts over
2,000,000,000 containers per
week
• Based on 15 years of container
and orchestration R&D
• Builds on lessons learned (e.g.
labels)
• Distributed systems genetics:
– cgroups
– mapreduce
– Bigtable
"Everything at Google runs in a
container… Everything"
Joe Beda, Kubernetes Founder

7. • No middleware, databases, analytics, or storage
• No marketplace or set external services
• No Infrastructure automation
• No source-to-image lifecycle management or policy
• No logging, application telemetry or notification service
• No configuration management
• No machine configuration, maintenance, management, or self-healing systems

Use Cases
- DIY Self-Service Platform for
Many Applications
- Component for Few, or Single,
Distributed App
- Operation’s Container
Orchestration
- Hosting Off the Shelf
Applications

14. APPRENDA.COM
DIY Platform
Build a self-service platform, likely managed by operations, where
developers can host application
• Seen in some of the F100
• Do not underestimate effort
• Benefit is that the platform is your intellectual property
• Downside are cost, management, lock-in to SW company with one
customer (yourself)
• CIO/CTO/Operations project

15. APPRENDA.COM
Component for Distributed App
Build, or repackage, a single or few application for Kubernetes or containers
• Very common. Starting point for most Kubernetes initiatives
• Operations will need to host these applications
• Reach inflection point as operations host more applications where
centrally hosted K8S in operations makes sense

16. APPRENDA.COM
Operation’s Container Orchestration
Operations deploys Kubernetes to manage containers, but it does not have
self service SLAs for developers
• Ops can use Kubernetes as VMware for the container world
• Benefits - less virtualization, middleware and operating systems
• Will see more often when more COTS and framework options

17. APPRENDA.COM
COTS & Frameworks
Hosting off the shelf applications and frameworks (e.g. redis) on Kubernetes
• Early Days
• SIG-Apps - http://goo.gl/VR0HTj
• Future state

18. APPRENDA.COM CONFIDENTIAL
Developers have been presented with the challenge of writing
code on laptops and desktops that provided nowhere near
enough power to run the OSes, middleware, and application
servers that would eventually host their applications
Sinclair Schuller
CEO of Apprenda

What is Minikube?
• Local, single-node Kubernetes cluster - EASY
• Runs inside a VM (VirtualBox, VMWare Fusion, KVM, xhyve)
• Includes:
– Lightweight Linux VM
– Docker
– All Kubernetes components
• Optimized for local development and fully compatible
• Supports additional features like DNS, Dashboard, ConfigMaps/Secrets
