VMware’s hybrid cloud – a discussion with customers

Summary: Hybrid cloud gets a lot of press and VMware are claiming a stake in a market predicted to grow massively over the next few years. I discuss with customers what vCloud Air can offer businesses and what you need to consider.

On Tuesday 25th November I took part in an online discussion about the hybrid cloud with a couple of vCloud Air customers (Schalk van der Merwe from The Hut Group and Matthew Garrett from Cloud Business) along with VMware’s Rick Munro (Chief Technologist, vCloud, EMEA), and well known blogger Julian Wood. The discussion lasted around an hour and we discussed topics such as;

  • Is hybrid cloud just a stepping stone to the public cloud?
  • Is data sovereignty an issue for customers?
  • Are clouds converging to a global platform or diverging into niches (market verticals like healthcare, government etc)?
  • Is the rapid pace of change a challenge when making a business case for cloud?
  • Does adopting cloud lead to changes in established ways of doing business, from a people/process/technology perspective?

You can view an edited version our discussion below which (luckily for you dear reader) is only 18 minutes;

If you don’t have time to watch, some of my takeaways were;

  • agility is a key driver of cloud adoption, more so than cost savings (which in my experience aren’t always expected or delivered). Results speak louder than RFPs!
  • it’s not a case of ‘private’ OR ‘public’ OR ‘hybrid’ cloud – you can, and probably should, use all three depending on your use case
  • start small and build on success (just as the DevOps crowd advocate!).
  • hybrid cloud may be a stepping stone, but it’s essential to take a first step
  • vCloud leverages your existing knowledge and skills so is an easy first step

Personally I think hybrid cloud is here to stay. Mainframes are still with us (from the 1950’s) and email has been available as a SaaS offering for at least 18 years (Hotmail started in 1996) yet today there are still thousands of companies running their own email systems.  For many enterprises ‘hybrid cloud’ will actually mean a multitude of different clouds including vCloud Air, AWS etc, despite the additional management overheads that will introduce. Time will tell!


Transitioning away from vCloud Director – the unspoken plan

Summary: vCloud Director, once the flagship product spearheading VMware’s vCloud Suite, is slowly winding down for enterprise customers – potentially leaving some companies with a roadmap challenge.

Having just started work for a cloud service provider in the Channel Islands (Foreshore) my focus has shifted and vCloud Director is a product I’m working with. After VMworld last year I wrote about how badly VMware communicated their product shift away from vCloud Director (vCD) and this year I’ve not seen much sign that communication has improved. At VMworld Barcelona this year only one session out of over 400 was about vCD. Yep. One (although to be fair it was ‘vCD roadmap for service providers’ – more on that later). How the mighty have fallen.

 What do we know about the vCD roadmap?

As announced last year the vCloud Suite roadmap involves the current features moving into other products, both in the vCloud Automation Center (now vRealize Automation) and the core vSphere product. It’s likely that the provisioning aspects will go into vCAC (now vRealize Operations) and some of the network functionality (multi-tenancy in particular) will go into the ‘core’ vSphere product. vCloud Director will continue to exist for service providers but for enterprise customers there is a migration to be done. There was also the following statement;

Yes, VMware will offer a product migration path that enables customers and partners to move from vCD to VCAC…

So far, so good.

So what’s the problem?

The problem is it’s been a year since that announcement and there’s been near radio silence since then. If enterprise customers need to transition off vCloud Director then VMware need to provide information, preferably sooner rather than later, on how that’s likely to work.

Visio diagram of an Autolab environment

A few months ago I found myself wanting to use my home lab, but the whole environment had become very out of date. Rather than build everything from scratch and by hand it was the perfect excuse to try Autolab, a project which I was aware of (I’ve met the creator Alastair Cook a couple of times at VMworld) but had never found the time to deploy. For those not familiar with Autolab it aims to automate the build-out of a portable lab environment consisting of virtual networking,  storage, and compute using vSphere, and includes vCloud Director, View, and Veeam.

My first thought was ‘Does Autolab do what I need?’ and while the documentation was pretty good the overall environment (in particular the networking) which Autolab created wasn’t immediately clear to me. In the end I did use Autolab and while it did some of what I needed I wanted to see if I could integrate or improve the build using my existing setup (I have shared storage and multiple VLANs in my lab already). While sketching out my options I decided to create a proper Visio diagram of a completed Autolab build for future reference and thought it might be useful to others too. I’ve sent it on to Alastair so it may turn up in the next release (assuming there is one).

You can download it in Visio or .JPG format.

UPDATE 4th Jan: Autolab 2.0 has now been released but is largely unchanged. The DC and vCenter servers now support W2k12 and the storage VLANs (16 & 17 in the diagram) are no longer used – their subnets remain the same however.

Autolab v1.5

What Autolab is trying to achieve (freely distributable lab build automation) is highly commendable but given the ease of use and free availability of VMware’s Hands On Labs combined that with the rapid pace of development for many VMware products (vCD isn’t even available anymore unless you’re a service provider) and I wonder if Autolab in it’s current form is sustainable. To encapsulate and therefore make portable an entire working dev/test environment, the aim of the Autolab networking, is a perfect use case for NSX although if you want that for free you’ll have to look to open-source equivalents (OpenFlow et al). Time will tell!
