VMware + OpenStack: Better Together

4

… industry leading data center virtualization

technologies that enterprise IT already

knows how to operate.

An industry-wide API + tool

ecosystem that cloud application developers love…

5

What is Openstack?

6

Openstack is NOT…

A single open source project that you can download and install

A hypervisor

A storage platform

A public cloud service

A VMware competitor

OpenStack as a Framework

• Use a single cloud API ecosystem with different underlying virt. technologies

• Use a variety of deployment models (from do-it-yourself to a vendor solution)

OpenStack is a flexible cloud framework that lets you…

& Cloud Admins

What SW/HW infrastructure technologies and/or vendors

meets my needs for advanced features, ease-of-use, cost

structure, scale, reliability, monitoring, performance,

SLAs, troubleshooting, etc?

VMware’s OpenStack Integration: Embracing Customer Choice

• Devops-friendly + vendor-neutral API ecosystem for your developers.

• Many options when deciding how to build and/or buy your cloud solution.

• Best-in-class software-defined datacenter (SDDC) technology, as individual components or as an integrated software suite.

…with the innovation, reliability, and ease-of-use of VMware

The benefits of the OpenStack framework…

What are VMware’s Goals with OpenStack?

Contribute to OpenStack

• Integrate VMware compute, network, storage SW with OpenStack.

• Make OpenStack better, helping customers succeed with their cloud effort.

Help our Customers Succeed with OpenStack.

• Show customers how VMware components help them run a better cloud.

• Work with ecosystem to make sure it is easy to deploy OpenStack + VMware

Our Goal: Make VMware the best and easiest way to run OpenStack

VMware’s focus on SDDC allows VMware to embrace customer choice.

12

Choosing a Compute Driver: Why vSphere for Nova?

Technical:

• Purpose-built hypervisor platform provides

unmatched combination of reliability, security, and

performance.

• Availability features (vMotion, HA) and compatibility

testing protect critical production workloads.

• Advanced resource management (e.g., DRS,

SDRS) better utilizes HW, providing higher density

and avoiding “noisy neighbors”.

Operational:

• Enterprise-polished solution simplifies adoption.

• Enterprises already have the expertise.

• Vast array of VMware + Ecosystem tools to manage

the infrastructure layer

• Deploying OpenStack can be as simple as

deploying a single “controller” VM.

Choosing a Network Driver: Why NSX for Neutron?

Technical Capabilities:

• First and most production-hardened network

virtualization solution.

• Doesn’t relay on physical network for VLANs,

FW, etc. Works with gear from any vendor.

• The technical “details” matter:

• Tunneling packet performance

• High-availability + scale-out model.

• “Distributed” network services.

Compatibility + Ecosystem:

• Works on KVM, XenServer, and ESX.

• Integrations with many HW Switch vendors to allow

NSX to manage physical workloads.

Operations:

• Troubleshooting tools to view how virtual networks

are built, impact of physical network failures.

Choosing a Block Storage Driver: Why vSphere for Cinder?

Simple but Powerful:

• Single driver works with any vSphere

validated storage (NFS, iSCSI, FC)

• Leverages huge validation efforts

across many vendors.

• Includes VAAI array acceleration work

for snapshot, clone, etc.

Enables VMware “virtual SAN”:

• Provides shared storage leveraging

SDD/Hard-disks on the hypervisor.

• Low-cost storage devices, but with

accelerated by local SSD cache.

• SSD cache is configurable per-disk,

allowing extremely high IOPs for data

intensive workloads.

Choosing an Images Driver: Why vSphere for Glance?

Simplified Storage Management

• Use the storage already previsioned for VM

disk use to store images.

• No need to maintain separate storage (e.g.,

Swift). Can use existing SAN or vSAN.

Efficient handling of Images during

boot + snapshot operations:

• VM boot does not require streaming an

image through Linux glance server. Can be

an efficient inter or intra-datastore

operation.

• Similar benefits for images created by

snapshotting a root disk or volume.

Management Technologies with OpenStack

Application Management:

• vCloud Automation Center (vCAC) 6.0

includes support for consuming from

OpenStack clouds, in addition to other

back-ends like vSphere, KVM, + AWS.

• Provides governance, policy, workflow,

and costing, which are not present in

OpenStack.

Infrastructure Management:

• vCenter and the NSX manager provide

base troubleshooting capabilities for

investigating issues at SW layer.

• vCenter Operations Management

(vCOPs) provides advanced visibility

into the relationships between different

elements, health monitoring, anomaly

detection, etc.

• vCenter Log Insight ….

25

Internal OpenStack Development Cloud

Started as OpenStack “Essex” based cloud, running with Nicira

NVP (now VMware NSX) and KVM.

Now ~200 physical servers, 5K VMs, 1K+ networks.

Use cases:

• Development machines.

• Build + Continuous Integration.

• Training + Development Lab Environments (customers, staff, partners)

Rich networking capabilities of NSX enables

• Private networks without VLANs that span racks.

• overlapping IPs

• remote bridging of networks to partner datacenters.

• Multi-hypervisor VM connectivity (KVM + vSphere)

Recent expansions use vSphere + vSAN for compute + storage.

• Much better density with (1) DRS and (2) vSAN eliminating dedicated storage nodes.

• Easier cloud operations from better visibility, infra handling of node failures.

Try it Yourself: VOVA and VMware Hands-on-Labs

VOVA + VMware OpenStack Community:

https://www.vmware.com/go/openstack

VMware + OpenStack Hands-on-Lab:

http://www.vmware.com/go/openstacklab

“VOVA”: A tool for experimenting with OpenStack + vSphere

• A single OVF file containing a full OpenStack install.

• Deploy VMs via OpenStack to an existing cluster.

• Import, answer a few questions, and go!

• OpenStack on vSphere in under 20 minutes.

Also available as a Hands-on-Lab:

• No lab infrastructure required. You just need a browser.

• Hands-on-Labs site provides a virtual desktop to a remote lab

environment running in VMware’s cloud.
