Network OS Middleware ...

Traditional approach: handcrafted automation silos

You need to be a manufacturer to win the game!

How to Build an App: 1. Have Idea 2. Get Budget 3. Code 4. Test 5. Launch 6. Automatically Scale

How to Build an App: 1. Have Idea 2. Get Budget 3. Submit VM Request request 4. Wait 5. Deploy framework/appserver 6. Deploy testing tools 7. Code 8. Test 9. Configure Prod VMs 10.Push to Prod 11. Launch 12.Request VMs to meet demand 13.Wait 14.Deploy app to new VMs 15.Etc.

VirtualizedHow to Build an App: 1. Have Idea 2. Get Budget 3. Submit hardware acquisition request 4. Wait 5. Get Hardware 6. Rack and Stack Hardware 7. Install Operating System 8. Install Operating System Patches 9. Create user Accounts 10.Deploy framework/appserver 11. Deploy testing tools 12.Code 13.Test 14.Buy and configure Prod servers 15.Push to Prod • Launch 1. Order more servers to meet demand 2. Wait… 3. Deploy new servers 4. Etc.

IT Manufacturing means...

PaaS is a perfect fit!

STANDARD PARTS. STANDARD PROCESS.

STANDARD INFRASTRUCTURE. BUILD FOR CHANGE.

Standardized. Interoperable. Multi-vendor.

STANDARD PARTS. STANDARD PROCESS.

STANDARD INFRASTRUCTURE. BUILD FOR CHANGE.

Eliminate redundancy. Encourage flexibility.

Drive modularity.

Jenkins (CI)

Maven (Builds) Apache

(HTTP)

CodeJBoss

Git Repo MySQL

STANDARD PARTS. STANDARD PROCESS.

STANDARD INFRASTRUCTURE. BUILD FOR CHANGE.

Process drives tools. Not the other way around.

RHEL RHEL

Runs on RHEL on Any Infrastructure

RHEL

Public / Hybrid / Private / Virtualization / Bare Metal

Willow Run

STANDARD PARTS. STANDARD PROCESS.

STANDARD INFRASTRUCTURE. BUILD FOR CHANGE.

Turn craftwork into commodities.

Design for improvement, not function.

PaaS needs to become Service Oriented

InfrastructureThe world is changing from Client-Server to Mobile-Cloud …

Is your Infrastructure able to handle that?

But does that really taste well?

We Want Composition?

We want Portability• JVM

• Virtualization

• Mobile Numbers

• Laptops

• iCloud

• Cloud Services

http://www.oxforddictionaries.com/definition/english/portable

portableAble to be easily carried or moved,

especially because being of a lighter and smaller version than usual:

a portable television

Software Vendors react• Lightweight App Server

• Lightweight Web Frameworks

• Micro Services

• Dynamic Endpoints

• Etc.

IT needs to be versatileSource: http://bit.ly/1iMOAdd

Something new on the HorizonSource: http://bit.ly/1gyjX71

ContainersSource: www.glynlowe.com/containers

Traditional Enterprise OS• Single Userspace Runtime

• Environment and Lifecycle defined by Host OS

• Trend to isolate Appls on HW Level

• Managed by IT (Limited Delegation)

• Very Limited Flexibility

Virtualization and IaaS• Application Isolation per

VM

• Application and Runtime abstracted from Hardware

• Complex Multi-Level Management of Host and VM Layers

App Delivery using Containers• Application packaged with

individual Runtime Stacks

• Multi-Instance, Multi-Version, Maximal Flexibility

• Provides Shared Services to be be re-used inside containers

• Clustering, Orchestration

Containers vs. Virtualization• Not either one or other

• Virtualization: Vertical Abstraction

• Containers: Horizontal Segmentation

• Horizontal Application Isolation

• Lightweight Delegation

• Application Virtualization

• Density

Layering

• Images can be layered

• Layering Model supports Specialization

• Base Image / Core Build

• Add Consumable Services on Top

Sharing and Self-Service

• Images are pushed to a central Registry

• Can be pulled by any developer

• Any Environment, Any Application Version, Runs Anywhere

Still isolated on the Host• Applications

• can be Linked

• can talk to each other

• What about scalability?

• What about Portability?

Self ServiceProvisioning

GOALS Provision complex environments in minutes

Easy scaling of developer teams

Use Case „Continous Delivery“

GOALS Optimize operational efficiency

Increase deployments by a factor of x6

PaaS enables Dev and Ops to focus on what they’re

good in.
