1. Interoperability Between Modern Clouds using DevOps
Probing Presentation
Sean Bird and Mike Corley
CSE 775 (Spring 2017)

2. Project Goal (refresher)
Establish a Hybrid Cloud (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]

3. DevOps Overview
DevOps (Development and Ops)– out growth of Agile manifesto
Agile embraces constant change, DevOps embraces constant test, constant delivery
How? Break down the silos sub teams (Dev, Ops, Test, Q/A). Everyone becomes a first class citizen.
Principles
Collaboration - TFS, etc.
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

5. Enabling Technologies
Openstack (complete private Cloud deployment)
Multi-level virtualization
libvirt – hypervisor management
Traditional virtual machines augmented with micro services
Containers (Docker)
Lots of tools that enable DevOps
Focus on automation, orchestration, and configuration management.
Linux
Interesting:
Hybrid Cloud (private cloud and public cloud) deployment and a public Cloud such a Rackpace/TryStack, Amazon Web AWS->EC2, Azure

6. Demonstration for today
Complete Openstack (Private) Cloud (IaaS)
Build/install cooperative service(s) model to 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)
Demonstrate: Automation, infrastructure as Code (IaC) examples
Survey Public Cloud Providers
Amazon (AWS -> EC2), Azure, Rackspace/Trystack (public Openstack SandBox):
Docker Container Examples
Running Windows 7 in a container (yes! Windows 7)

7. Openstack deployment on a VMware
Hardware: Dell Precision m6500 (Intel i7-CPU), 32g memory
Windows 10 Professional (Host Operating System)
VMWARE Workstation pro (v12) VM

8. Openstack Cooperative services Concept

9. Containers

10. Container Image layer (Stack) Concept

11. 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

12. Hardware Emulation (x86 Intel)
Container 1
eth0
tap0
VM_NET (eth0)
br0

14. Next Steps: Finishing Surveying Tools and standup DevOps environment
Openstack, and (AWS or Azure)
Chef, Heat,
Develop, deploy ZeroMQ application in the Public cloud and consume expose/share data in private (on premises) cloud
