The OpenStack Project

OpenStack DOAG Regio Hannover 14.12.2016


Motivation for OpenStack Private Clouds

• Operational Efficiency

– Reduce Deployment Time and Efforts

– Enable Self-Service

– Provisioning of Multiple Heterogenous Clouds

–One Management Tool for Multiple Clouds

• Reduce Costs

• Standardization and Reduce of Complexity

• Unified Application Deployment Model

Operational Efficiency, Cost, Innovation, Multiple Cloud Strategy



What is OpenStack?

• Open source cloud software

– Generic solution for IaaS, PaaS, and SaaS

– Bare metal provisioning to service catalog

• Combines compute, network, and storage resources – Self-service dashboard

– Services exposed through RESTful APIs

• Originally created by NASA and Rackspace for Linux

General Architecture and Use Cases

OpenStack Clouds



Basic Concepts: Virtualization for the Workload

• The Platform for Nova Instances

– Ressource Management (CPU, Memory,...)

• Provide Boot Storage Access

• Provide Application Storage Access

• Provide Network Access

Basic Concepts: Network Virtualization for the Cloud

• Networking for Tenants

– Split into "Broadcast Domains"

• Routing between Tenants

• Routing to External Networks

• Address Translation

• Firewalling

SDN for servers and switches

Orchestration with OpenStack


• Manages complex Group of connected Cloud Resources

• Tiered Application Deployments spread across multiple VMs

• Provide MetaData and UserData to Nova Instances

• Control Orchestration Flow

• Clean-up the Stack on removal

• Described through Templates

Live Demo – Orchestration with OpenStack


Building a Cloud



• Out-of-the-Box Ready to Use

– Creating a private Cloud is different than just installing a Server

– Designing the Cloud (Networks !)

– Design and Configure the underlying Infrastructure • Overall Integration

• Dependent on Expertise, Experience, Vendors, Maturing Technology

• Just a product

– 6 month Release Cycle

– Support lifespan linked to Release Cycle

– Update capability is Challenging • Update a Cloud Node

• Update the Cloud

• Free

–OpenSource does not mean free

– Investment needed to set up and support environment

Road to Success

• Start with a Clear Vision

• Establish a Team

– Project Sponsor, Customer (IT Dept & Users), Vendor and Partner

• Proof of Concept Matters

– Check what Really Works and Constantly Rethink and Rework Concepts

–Match Expectations, Requirements and Cloud Features

• The Road to Cloud is more than just Creating the Cloud Infrastructure

– Creating Images, Defining Flavors/Shapes, Software Deployment

– "Cloudifying" Internal Processes

• Engage and Convince the Prospective Users Early
