3. Project Goal (refresher)
Establish a Hybrid Cloud (an environment) composed of cutting edge technologies to enable DevOps.
What is DevOps?
DevOps ("software DEVelopment" and "information technology OPerationS") is a term used to refer to a set of practices that emphasize the collaboration and communication of both software developers and information technology (IT) professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably [1]

4. DevOps Overview
DevOps (Development and Ops)– out growth of Agile manifesto
Agile embraces continuous change, DevOps embraces continuous test/integration/delivery/deployment
How? Break down the silos sub teams (Dev, Ops, Test, Q/A). Everyone becomes a first class citizen.
Principles
Collaboration
Use tools that influence collaborations/enforce policy
Infrastructure as Code (IaC)
entire environment (servers/links/platforms/apps/configuration) all represented as scripts stored in version control
Tools: Heat, AWS Cloud Formation, Docker, Chef, Puppet, Vagrant, Docker
Automation
Script as much manual processing as possible!
Continuous Integration/Test/Delivery/Deployment
Tools: Jenkins/Team City/AWS DevOps
Monitoring:
Cloud watch (AWS), Ceilometer (Openstack), VictorOPs

6. Containers

7. Container Image layer (Stack) Concept

8. Flexible OS Stack (Run Linux or Windows)
XenServer Hypervisor
Linux Virtual Machine
Docker Engine
Base Image: Bins/Libs /Dependencies
QEMU (Bin)
Windows OS Guest
Image Layers
QEMU: Machine Hardware Configuration 1
Linux OS Guest
QEMU: Machine Hardware Configuration 2
Update respective layers to extend new machine hardware and Operating System type
Running container instance: build from image
Shares host OS with other containers

9. Implementation/Demonstration

10. Demonstration for today
Demonstrate: (DevOps principles: Automation and Infrastructure as Code) in a hybrid cloud composed solution
Openstack (private/on premises), Public Cloud Provider: Amazon (AWS -> EC2)
Key component is the orchestration tools: HEAT, Cloud Formation
Complete Openstack (Private) Cloud (IaaS) deployment
Cooperative service(s) model controller, 10 processing nodes
Keystone (identity) management service (controller) (1 node)
Horizon (Dashboard) service ( 1 node)
Nova (Compute -- hypervisor) service (2-3 nodes)
Neuron (Networking) (virtual networking) service (1 node)
Cinder (Block storage – LVM partition management) (1-2) nodes
Glance (Image) service (1 node)
Swift (Object storage) service (1-2 nodes)
Heat (Application orchestration – Restful) service (1 node)
AWS-EC2 (Amazon Elastic cloud)

11. Demonstration: Application Deployment
MariaDB instance hosted inside AWS Docker container
Containing SQL database for wordpress wiki page
Open public IP with MariaDB service hosted on port 3306
Wordpress web host deployed in Openstack
Using Openstack Heat orchestration

12. Design: Highest Level (10,000 ft view)
Public - AWS
Public Data Storage
MariaDB
Private Data Storage
Wordpress Front End
Private - Openstack

13. Openstack deployment on a VMware
