ARM Introduction

Over 1100 licensesGrowing by ~100 every year

Nearly 350 potential royalty payers

10.4bn ARM-based chips in ‘13~20% CAGR over last 5 years

ARM-based servers on track▪ 16 licenses now signed for server

applications▪ 2013: Chip development▪ 2014: Software optimization accelerates▪ 2015: First production systems▪ 2018: ARM expects 10-15% share

• Linaro is a collaborative software engineering company funded by members

• Instead of duplicating effort for common open source software, competitors share development costs and software is built once

• The work is carried out in the open, tested and then upstreamed into the relevant open source projects: kernel.org, AOSP ...

• The Linaro Enterprise Group (LEG) was formed e/o 2010 by fourteen companies• enable the ARM server ecosystem• share costs of the enablement engineering• focus on standards, avoid fragmentation• identify, test and optimise workloads and core libraries

Engineering (1): enablement

Engineering (2): workloads

it’s time for some cloud stuff now….

Recovery as a service (RaaS)

Mobility as a Service (MaaS)

Let’s start with one remote machine

Let’s add few more remote machines

It is not sustainable and not scaling

Let’s go back to one control point

Let’s add nodes now

We can now run multiple VM’s per node

We can run multiple runtimes per VM

And one or more apps per runtime

PaaS

SaaS

IaaS

It’s all ...as a Service

It’s running on ARM 64-bit now!

• Long cooperation with Canonical and Red Hat engineers• Reusing pre-built DevStack packages from Ubuntu• Leveraging on LEG kernel and Linaro KVM work• running on real ARM 64-bit hardware, APM X-Gene• running all applicable Tempest tests

• Ongoing• PackStack packages from Fedora• libvirt on XEN

What’s the effort and cost?

let’s review few open source projects

let’s rely on ohloh.net and the co.co.mo. model

• OpenStack is still relatively small but growing as fast as the Linux Kernel itself…

What about OpenStack on ARM then?
