IT Problem: Complexity Explosion

• Manual and “hand-crafted”

• Tightly bound to individual skills

• Reproducibility?

• Quality? High defect/error rate

• Magic configurations

• Expensive and slow

IT Today: Stuck Pre-Industrial Revolution

Manufacturing before the Ford Model-T

8

• Use machines instead of manual labor

• Assemble with standardized parts

• Break large and complicated processes into smaller and easier sub-processes

• Apply specialized and general labor accordingly (engineers vs. assembly workers)

• Deliver agility and responsiveness

Why use Crowbar?

• Crowbar takes DevOps to the Cloud‒ Automates infrastructure provisioning and deployment

‒ Highly customizable deployment

11

● Slow ROI● Long term maintenance ● Business liability● Not standardized● Very expensive

Hand Assembled or Homegrown

● Difficult/impossible to integrate/extend

● Vendor-lock in● Lack of ecosystem● Very costly

ProprietaryCommercial

● Some lack a successful track record

● Some limited in configuration capabilities

● Lock-in risk if developed by single entity

Other Open Source

● Narrowly focused Installers● No ability to “operate”

environment beyond install● Sales tool

How Crowbar Assembles the Cloud

13

CloudOps: The Cloud Frontier

• Cloud‒ Elastic and oversubscribed

• Ops‒ Stable AND dynamic

‒ Maximum utilization!

• Crowbar Benefits‒ Delivery of Cloud services

as needed

‒ Managed resilience

‒ Rapid recovery from node failures

‒ Automated and dependable DevOps and CloudOps

14

Core Concepts

• DevOps / Reference Deploy

• Open Operations / Best Practice

• Late Binding > Continuous Deploy

• Layered / Interconnected Orchestration

• Network Abstraction for DevOps

• Physical Infrastructure is Complex (Net, NIC, RAID, Admin, etc)

15

• Includes all the components required to implement an entire cloud infrastructure including ecosystem partners

• Pluggable components deploy cloud infrastructure

• Allows for addition of proprietary IP and expansion by the community services and customers

• Can integrate with existing proprietary products

• Delivers basic data center services and required cloud infrastructure.

• Provision bare-metal servers from box to cloud WITHOUT user intervention (other than racking/cabling and some minimal configuration questions)

Assembly is Layered and Ordered

Crowbar Plus OpenStack“Boxes to working OpenStack in <2 hours”

• Crowbar’s birthright was as an OpenStack installer

• OpenStack is complex

• To create an OpenStack project, needed:

‒ To get cloud sites running quickly

‒ Cope with frequent updates

‒ Connect many moving parts

‒ Be part of the open source community

• Crowbar can deploy

‒ OpenStack (Grizzly, Havana)

‒ Hadoop

‒ Applications

• Crowbar API and Partial UI‒ Adds states and transitions to Orchestration‒ Customizes UI specific to barclamp‒ Visual extensions to nodes/networks/utils

• Chef Recipes‒ DevOps description of application‒ Enforced repeatable configuration

• O/S App Packages‒ Operating system dependencies (Debs and RPMs)

• Components and Scripts‒ Ad hoc configuration not covered by Chef
