Types of a cloud

12

Managing and (re)provisioning a DCN is difficult

Credit: Google

Build compute powers without vendor lock-in

Provide and build services, at lower costFacebook has 20,000 server per admin

Scale out easily by adding servers go to public clouds when needed (Cloud bursting)

OpenStack: Motivation and history

16

… and why OpenStack matters!

OpenStack Future (from its past!)

In 2012 Boris Renski (CMO) Mirantis made three arguments for money in OpenStack

Cloud is BIG $$$

Cloud will be open (Google, facebook, Rackspace back OpenStack)

OpenStack won the OpenCloud war (2012)

Average # of developers in an IRC channel as of 6/18

Mirantis raised $100 million as pure-play OpenStack in Aug 2015

Monetary Motivations (Enterprise and Entrepreneurs)

20

Job opportunity

“OpenStack continues to gain mindshare among enterprise CIOs …….. We continue to see OpenStack becoming the de facto open source option for deploying private clouds. However, this will accelerate only after more OpenStack-trained developers enter the workforce…..” [The 451Research Take (https://451research.com/openstack)]

OpenStack engineers make 36% more than other cloud engineers.Src: http://www.datacenterdynamics.com/

OpenStack: Managing your Cloud!

OpenStackProjects to control pools of compute, storage, and networking resource

Managed through API & dashboard

Open architecture, code, community!

Plugins (vendor specific)

OpenStack infrastructure abstraction --- connect any vendor

Open Architecture --- connect any tools with Open API

Open source (Apache license) softwareaccelerated innovation, community benefits

Plug-in architectureno vendor lock-in (hypervisors, storage soln, SDN soln)

On demand control of large pools of compute, network, storage

Enable IT automation

Multi-tenancy support with quotas and isolationability to control, monitor and monetize resources

32

Features/Benefit (high level)

Cinder: Managing block storage

Persistent block storage for VM instances lives through reboots and crashes

Can be used to create bootable volumesNo need for ephemeral storage!

Multiple volumes (disks) for a single VM

Can backup volumes, (perhaps) in swift!

A frontend to create and manage virtual disks and their VM association

Unstructured blobs, replicated in a ring across different zones

Default to three replicas

Objects accessible with a URLswift.example.com/v1/account/container/object

Massively scalable, but with eventually consistent behavior
