IT Transformation from Business's Perspective

10

Leading to Huge ROI Expectations in the Cloud

11

IT Transformation from Operation's Perspective

12

Still focusing on delivering Cloud Infrastructure

13

If you build it they will come...

Enter the Developer Realm

New Cloud World Order

The Expectation of “Everything”-as-a-Service

● Identity-as-a-Service

● Queueing as a Service

● Backend-as-a-Service

● Database-as-a-Service

18

Servicing Needs Beyond Infrastructure

IaaS (Infrastructure as a Service)

“How do I use this?”

• Servers in the cloud• You must build and manage everything

(OS, App Servers, DB, App, etc.)

SaaS (Software as a Service)

• Someone else’s app in the cloud (CRM, etc.)• You are restricted to the features of the 3rd

party application“I’m not sure this app

does what I need.”

19

IT Transformation ...from the Developer's Perspective

20

Multiple, Diverse, Complex Application Use Cases

● Require more than just “Infrastructure”

● Run on a diverse eco-system of application stacks

● Need to be secure, compliant and well-managed

● Scale or Fail

Platform as a Service fills out the Cloud Layer Cake

Key to a Successful Private Cloud Initiative: PaaS

● Expectation Management

● Add a PaaS Layer to your Cloud

– Increases Interoperability

– Adds On-Demand, Self Service

– (Security+Privacy+Control ) = Compliance

PaaSLanguages, frameworks, web servers

Services: Data, Messaging, others

Infrastructure as a Service gives you

• Network, storage & compute as an on-demand service

• Basically, servers in the cloud

• You’re still on the hook to configure & manage the cloud & stack

“How do I use this?”

24

Software as a Service gives you

• An on-demand application

• Nothing to install or configure

“This is all my customers and users care about!”

25

Platform as a Service delivers!

• Application run-time environment in the cloud

• Configures & manages both the cloud & stack for your application

“The cloud is now useful!”

26

Platform as a Service Benefits

● Automate Application Environment Deployment● Reduce Time to Market● Standardize Application Deployment● Security of Data● AutoScaling of Applications● Privacy & Control Over Data● Control for Corporate IT● Customize to Your Requirements● Mitigate Risk

So how does PaaS work it's magic in the Cloud?

• Broker – Management host, orchestration of Nodes

• Node – Compute host containing Gears

• Gear – Allocation of fixed memory, compute, and storage

resources for running applications

• Cartridge – A technology/framework (PHP, Perl, Java/JEE,

Ruby, Python, MySQL, etc.) to build applications

• Application – Instantiation of a Cartridge

• Client Tools – CLI, Eclipse, Web Console for creating and

managing applications

RUNS ON IaaS

OpenShift Origin is a PaaS that runs on top of Infrastructure

OpenStack RHEV VMWare

Amazon EC2 Rackspace Bare Metal

33

BROKER

An OpenShift Broker can manage multiple node hosts.

Fedora/RHEL Fedora/RHELFedora/RHEL

Brokers Node Node

Nodes are where User Applications live.

34

COMMUNICATION

Communication from external clients occurs through the REST API

The Broker then communicates through the messaging service to nodes

35

BROKER

The Broker is responsible for state, DNS, and authentication.

Recap: PaaS+IaaS = Successful Private Clouds

● Automate Application Environment Deployment● Reduce Time to Market● Standardize Application Deployment● Security of Data● AutoScaling of Applications● Privacy & Control Over Data● Control for Corporate IT● Customize to Your Requirements● Mitigate Risk
