OpenStack + VMware : Deploy, Upgrade and Operate Powerful Production OpenStack Cloud in Minutes!

It was 2011, and it was an exciting time

to be in the cloud business!

3

Cactus had just been released, and I was attending my first design summit.

4

Turns out, getting Cactus running in my lab was a *LOT* of work…

…and that was before Cinder, Neutron, Ceilometer, Heat, & many more projects even existed.

5

Managing it after I built it was kind of awkward in the early days…

Upgrades? Patches? Diagnosing problems? High availability? Existing workloads?

6…sometimes the problems proved both costly & painful.

This is not 2011.

This is not Cactus.

We’ve come a long way.

Now pull up a seat and let’s talk about what a modern OpenStack cloud should look like.

What is VMware Integrated OpenStack?

• It’s an OpenStack distribution• Deployed as a vApp in VC

• Uses upstream code and drivers• VMware is a major contributor to

OpenStack• It’s an OpenStack Powered™ product

(2016.08 compliant)• Integrated = uses a well tested stack:

• vSphere for compute• NSX or DVS for networking• VMDK driver on vSAN or any

vSphere-friendly storage• Can be managed with vRealize

tools• Got an Enterprise Plus ELA? VIO is free to download!

• Option to purchase support• Now shipping: VIO 3.0 (Mitaka)

• HA & compact modes• Import existing workloads• Much more!

Powerful Parts

Powerful Cloud

Let’s start with deployment…how easy is it to deploy?

Pretty easy!

• If you can deploy an OVA in vCenter, you can deploy VIO.

• Designed to be familiar for vSphere admins and simple for anyone.

• No need to learn a lot of new stuff to get started…use what you’ve already got and what you already know.

• Upload OVA file• Click on the vApp• Fill out a few fields (IP addresses, passwords, etc)• Go get a drink

Under the hood, we’ll be deploying a highly available OpenStack to your management cluster…

• HAProxy load balancer pair w/Keepalived• Control node pair• RabbitMQ nodes• MariaDB w/Galera Cluster• Compute node per VC cluster• OpenStack Management Server (OMS) for management tasks

Your ops guy (who’s been a VC admin for ages and knows his way around VC operations like the back of his hand) wants to vMotion a VM within a cluster? Go ahead!

Puts the power of both VMware and OpenStack in the palm of your hand!

Want to protect workloads with vSphere HA? You can!

Want to use the DRS or SPBM? Not a problem!

Use vCenter to see what’s going on and what’s in use? You’ll see OpenStack info in there too (instance ID’s, etc)!

Let’s not forget control plane/data plane decoupling…

• ESXi host goes down? VM’s rescheduled to another host in the cluster. (optional)

• vCenter goes down? All workloads keep functioning!

• Upgrading or patching services? No app downtime!

• Got cattle and pets? No problem!

• Reduced number of nova-compute instances reduces MQ/API chatter.

Ok, now I’ve got this awesome cloud

…but it’s empty.

I built it, but will the workloads come?

What if you could import your existing workloads and use them as OpenStack instances going forward?

• Imported instances can now be manipulated with Openstack API’s

• Networks imported as provider networks

• Achieve critical mass faster

• Existing templates can also be imported as Glance images

Ok, I’ve got a cloud and critical workloads on it. Now what about all the Day 2 stuff like:

• Operations

• Patching

• Upgrades

• Just plain being able to know what’s going on in my cloud

• Patching:• Upload patch to OMS• Patch staged and ready• Deployment and service

restart are automated• No downtime

• Monitoring• vRealize Operations

management packs for OpenStack

• LogInsight • vRealize Business for

costing• Or use whatever tools you

like…it’s OpenStack!

• Other stuff• Add new storage• Add new hosts or retire old

ones• Start/stop/restart services

Another way to find information about what’s going on in your cloud:

Just pull up your VC client.

Let’s take a minute to talk about upgrades...

How We Do Upgrades: Blue-Green Upgrade Pattern

Load Balancer

• Allows hardware to be swapped• Allows new control plane to be tested before going live• Very fast rollback• Allows for root causing of problems since both planes can be kept in event of failure• Skipping releases? No problem.• Leverages existing deployment code• Doesn’t depend on n-1 or n-2 compatibility in control plane components• Eases addition of new components/decomposition since green plane is “just a new deploy”

Kilo Control Plane Mitaka Control Plane

CONFIDENTIAL 25

Blue-green upgrades are testable, transactional upgrades: much less awkward than trying to upgrade pieces at a time.

“BTW just did an upgrade [from Kilo to Mitaka]...while drinking a beer and watching the game! How an OpenStack upgrade should be!”

“We just found out the customer upgraded recently…with no help. They didn’t even tell us they were doing it.”

So is anyone running important stuff on top of this?

• E-commerce platforms (yes, on Black Friday and back-to-school season)

• Telecom• Transaction processing/ticketing• CI/CD for dev teams• Automotive• NFV workloads• Live demos at OpenStack Summit

keynotes• Many more!
