Utility Computing – from Dream to Reality

I have been absorbing, analysing and sharing ideas with lots of people during VMworld Europe 2014 in Barcelona. From executive round-tables, roadmap sessions, panel discussions to one-on-one brainstorms or sharing a dream how the IT landscape would look like in 2020+. Utility Computing is forming from dream to reality in my opinion.

Flashback

If you take a look at the transformation IT has made since the millennium and the speed it is moving at now, is just surreal! In the past 10 years, virtualization has spread like a wildfire across the IT industry. In the beginning it was mostly explaining and convincing a lot of different people from different departments that virtualization is not a hype but a road ahead. Innovating, breaking barriers and tearing down the so called silo’s. Now virtualization discussions aren’t around if it is proven technology or not, now it is more about what’s next? At the first customer I applied virtualization, with a dream team, in 2005 we went from “nothing” to VMware in a production environment on ESX 2.5. Primary applications which have been successfully virtualized are Oracle, SQL and Exchange.
VMworld Europe 2009 Banner
The first time the phrase Utility Computing triggered me was at VMworld Europe 2009 in Cannes. What would happen with IT if you could buy and sell IT infrastructure-power with a standard unit of consumption measurement? What would be needed to handle IT infrastructure power like utilities as gas, water and electricity? How to break the bond between the hardware layer and the functionality on top of it?
How the world is transforming and reshaping the IT landscape
Without change there is no growth and thanks to technology the world around us moves and changes faster than ever. Organisations which do not organize their business processes to absorb and adopt change will remain behind. The revolution of Internet, Social Media, smartphones and tablets determines how people live, learn, play and work together. The way of communication between people and people and organizations change. Access to communication, information and applications have become indispensable and nourish the speed of economic and technical developments. Remain or become competitive and attractive in the market is the primary challenge for organisations.
If you want to manage change you will need to handle tree major components: People, Processes and Technology. If you forget to pay attention to one of those three, then it will go wrong fast these days.
However, the fact that change has become more frequent does not make such changes any easier.
The whole IT industry is currently being reshaped because of one tiny thing what triggered it: Virtualization! Virtualization makes it possible to break the bond between the physical hardware layer and the functionality on top of it. Now virtualization discussions aren’t around if it is proven technology or not, now it is more about what’s next?
In the past 10 years, the Fear for virtualization turned into a conscious choice of architecture in which many companies have a ‘Virtual unless’ handling policy now.

So What’s next?

So with this year’s theme at VMworld being No Limits matches 100% of breaking the barriers without limits. VMworld 2014 No LimitsIf we look at the whole data center you can define three major physical components that make up the IT infrastructure. These are Compute, Network and Storage. If controlled right they are managed by one platform, but most management I see in the field is a lot of element managers and some umbrella manager which tries to tie the things together in one platform. To make Utility Computing happen we will have to break the bond between physical and the functionality on top of it completely. In other words virtualise the whole data center.
The Software-Defined Data Center (SDDC)
Virtualization enabled the way for more automation by breaking the bonds with the physical under layer. VMs are standardized software containers. Software files that can easily be moved, copied and managed. A software-defined data center is where all infrastructure is virtualized and delivered as a service, and the control of this data center is entirely automated by software.
Enterprise IT will have to become more and more business-focused, automatically placing application workloads where they can be best processed. The Compute component is already mainstream and mature, this year during VMworld it was great to see how fast the network virtualization component (NSX) and the Storage component (vSAN) is being developed and moving to a maturity level and ready for becoming mainstream.It is a journey which is on a roll and moving faster and faster.
Each step of the journey will lead to efficiency gains and make the IT organization more and more service oriented.

The physical hardware below a SDDC becomes disposable pieces of technology, which in turn could be priced as a utility easier. If you can move VMs (functionality) in and out quickly this will lower the barriers to change. With a SDDC you can move a whole data center very easy to another location. This is also a high risk security wise because an administrator which controls the SDDC can move, copy or delete it in a push of a mouse click. But with these new challenges their are people who see opportunities and solutions to handle such risk like HyTrust with a Secondary Approval which makes sure that critical processes are handled accordingly.
Hybrid Cloud
The underlying infrastructure is more and more delivered as a Infrastrure-as-a-Service (IaaS) and on top of that a SDDC or components of the SDDC. With this combination you see more and more Private clouds being build and the next step will be combining them with Public clouds into a Hybrid cloud solution. Most companies choose a hybrid combination of on-promises and IaaS platforms. Where most of these options are build on the same VMware SDDC technology, so you easily migrate workloads among clouds and control and govern your hybrid environment from a single management interface. Their are also changes in the physical landscape, where the data center Compute, Networking and Storage resources are combined into a hyper-converged infrastructure.With hyper-convergence you integrate compute, network and storage where you eliminate the complexity and performance drag of (storage) networks and allows infrastructure to be scaled one node at a time. Alex wrote a good article about it here. VMware released EVO Rail and EVO Rack at VMworld. Combining all three hardware components into a single box! Another trend and vision what surprised me is from Diablo Technologies where they put Storage into a Memory slot. They are bringing the storage as close as possible to the execution processing unit (CPU). A simple, but brilliant move in my opinion.
If you already have a Private Cloud running built on VMware technology, you can easily expand your data center by connecting it to VMware vCloud Air. This is a SDDC with IaaS operated by VMware. It lets you quickly, seamlessly and securely extend your data center into the cloud using the tools and processes you already have. You can run your hybrid environment with a common, unified model for management, orchestration, networking and security. You can also connect your private cloud to Clouds operated by VMware partners. With all these connected clouds coming up, the underlying infrastructure for Utility Computing is being built as we speak. Maybe you can get paid for resources you expose to the utility cloud and which is being used by someone else. Making the use of resources more and more efficient world wide.
2020+ Fast forward
How will IT look like in 2020+? Who knows. I think from now till than a lot of organisations will be struggling with their identity and the value they offer to their customers. Workloads will move between hypervisors in and out of different sort of clouds where the world of applications, data and communication is integrated and running on an Utility Cloud with a standardized payment metric for Compute power. Will we see IT Power brokers perhaps? IT Service organisations using the world wide Utility Computing network?  It is good to see there is lots of competition, because competition drives innovation! Emerging technologies are likely to revolutionize the IT industry but also every organization as a whole, as well as our business processes and last but certainly not least your and my job! I see a world of possibilities for every person and organisation who is willing to absorb and adopt change without limits.


You feel something is trembling below the surface.

Hands-on labs: Horizon 6 with View


Hands-on labs 2014 monitoring wallEarlier this year Alex wrote an article about the release of VMware horizon 6. Today I had the opportunity to sit down at the hands-on labs and take a look at Horizon View 6. Two things, I was particularly interested in where the Published application features and the ability to use a virtual desktop trough HTML5.
During the lab I wasn’t able to load the Windows 7 virtual desktop. The desktop was presented to me but Windows seemed to be hanging on something. That is why in the screenshots below there is a screenshot of a Windows 2008 server desktop instead of a Windows 7 desktop.
VMware Horizon Application pools
VMware Horizon View Client
VMware Horizon View Portal
Entitling users for published applications is nothing different compared to entitling access to a desktop pool. Once entitled the user will get the application published in their Horizon View portal.
Opening a desktop from within your browser over HTML5 worked very well (apart from Windows having a problem). There was no installation required, nor did I had to use a plug-in to get the Desktop visible within my browser.
One thing that catched my eye while reading through some of the documentation was the statement that VMware had removed the option to run desktops in “View local mode”:
“In this View release, the View Local Mode capability has been removed from the Windows client. The feedback that VMware has received is that the Local Mode capability is incredibly valuable for customers who cannot always access an online desktop, but that our implementation needed improvement.
This experience has led VMware to invest in providing a better offline virtual desktop solution leveraging our award-winning desktop products, VMware Fusion Professional, VMware Player Plus, and VMware Mirage. We believe that this new containerized desktop strategy will give our customers the best local virtual machine experience in the industry.
Over the past several years, VMware has added Virtual Machine Restrictions to our desktop products, which allow an administrator to encrypt the virtual machine and prevent a user from modifying virtual machine settings that affect the integrity of the secure container. We have also added features such as expiration, so that the policies available in VMware Fusion Professional and VMware Player Plus are comparable to the existing Local Mode feature set. Including Mirage in this picture eliminates the need for users to check in or check out their desktops to receive updates and enables administrators to utilize the Mirage layering capability, backup features, and file portal.
Overall, we believe that this change will deliver a great end user experience and make the management of offline virtual machines much easier. It also extends the offline capability to run on Windows, Linux, and Mac OSX!
New customers interested in offline virtual desktops should purchase Horizon Mirage (which includes VMware Fusion Professional and VMware Player Plus) or one of the suites that includes both the Mirage product and Fusion Professional.
Existing customers should be confident that VMware will continue to provide support for the Local Mode feature in VMware Horizon View 5.x until at least 2017, which will provide plenty of opportunity to evaluate the new offering and plan their migration.”
Now I haven’t had any customers yet that where using offline virtual desktops so I am not sure if this will prevent companies to migrate to Horizon View 6. Hopefully customers can cope with this decision.

VMware Announces General Availability of VMware Virtual SAN

VMware, Inc., the global leader in virtualization and cloud infrastructure, today announced the general availability of VMware Virtual SAN, VMware's first Software-Defined Storage product. 
Built directly into the VMware vSphere kernel, VMware Virtual SAN provides a new tier of hypervisor-converged storage. The software abstracts and pools internal magnetic disks and flash devices from industry-standard x86 servers to produce a high-performance and resilient shared datastore for virtual machines (VMs). According to internal benchmarks, VMware Virtual SAN performs:
  • 2 million input/output operations per second (IOPS) on a read-only workload on a 32 node cluster; and, 
  • 640,000 IOPS on a mixed workload on a 32 node cluster.
"Today VMware changes the way that storage has been operated to date," said John Gilmartin, vice president and general manager, SDDC Suite Business Unit, VMware. "VMware Virtual SAN is a radically simple storage solution optimized for virtual environments that brings an application-centric approach to storage management. Customers that know VMware vSphere know VMware Virtual SAN, and can rely on that familiarity to hit the ground running with VMware Virtual SAN."

"VMware Virtual SAN enables us to scale our storage infrastructure and gives us the redundancy we require to help bring our solutions to market faster to our Line of Business customers," said Frans Van Rooyen, Cloud Architect, Adobe Systems Incorporated. "With VMware Virtual SAN, we use policy based management to automate storage aggregation across a large distributed environment while maintaining the same hardware platforms we know and use today."

"With VMware Virtual SAN, Itrica now has the capability to right-size storage solutions for our customers," said David Sampson, CTO, Itrica. "We can custom engineer IO, and scale on demand as customer capacity needs grow. Having a hypervisor-converged storage solution that's spread across our host machines, replicating data all the time, and operating in a similar model to how compute virtualization works, makes perfect sense for what we're trying to accomplish."

Simple, High-Performance Storage for Virtual MachinesVMware Virtual SAN simplifies storage provisioning and management while reducing total cost of ownership (TCO) enabling a fundamentally more agile operational model. VMware Virtual SAN provides the reliability and robustness of an enterprise storage system, and is highly resilient protecting against data loss in the event of any hardware failures. It is ideally suited for several use cases in virtual environments such as Virtual Desktop Infrastructure (VDI), test/development, and disaster recovery. Features include:
  • Hypervisor-converged architecture: Embedded within the VMware vSphere kernel, VMware Virtual SAN delivers the most efficient data path for superior performance while minimizing resource utilization resulting in the consumption of less than 10 percent of CPU resources. 
  • High performance with elastic and linear scalability: VMware Virtual SAN uses flash to deliver performance acceleration through read/write caching. The software provides a granular and elastic approach to provision performance and capacity enabling customers to linearly scale their clusters on demand by adding nodes to a cluster or disks to individual nodes 
  • Storage Policy Based Management: With storage policy based management, VMware Virtual SAN shifts the management model for storage from the device to the application. A single VMware Virtual SAN datastore can provide differentiated service levels based on individual VM policies. For administrators, there are no complex configurations through LUNs or volumes, they avoid over provisioning, and can change policies easily. With automated provisioning and management, administrators improve the ability to meet Service Level Agreements (SLAs). 
  • Integration with the VMware stack: VMware Virtual SAN is easy to configure and deploy requiring two clicks using VMware vSphere Web Client. Its integration with VMware vSphere enables customers to use data services such as backup, cloning, replication and snapshots as well as features such as Distributed Resource Scheduler, High Availability, vMotion and Storage vMotion. Additionally, VMware Virtual SAN is interoperable with VMware Horizon View 5.3.1, VMware vCenter Site Recovery Manager, VMware vCenter Operations Management Suite and VMware vCloud Automation Center.
A hardware independent solution, VMware Virtual SAN can be deployed on a wide range of servers. Customers have two options for deploying VMware Virtual SAN - VMware Virtual SAN Ready Nodes (pre-validated configurations of servers), and a component-based hardware compatibility list that enables customers to pick and choose the components they prefer. More than 150 components and 13 Ready Nodes are certified with VMware Virtual SAN today. The VMware Compatibility Guide for VMware Virtual SAN is accessible at: http://www.vmware.com/resources/compatibility/search.php?deviceCategory=vsan

Helping Customers to Reduce TCOVMware Virtual SAN helps customers to reduce Total Cost of Ownership (TCO) through Capital Expenditures (Capex) and Operating Expenditures (Opex) savings. The software takes advantage of server side hardware economics by pooling internal magnetic disks and flash devices from industry-standard x86 servers. Customers avoid large upfront costs by starting small and adding disks or nodes to their VMware Virtual SAN cluster as capacity or performance needs arise without disruption. VMware Virtual SAN also helps customers to achieve Opex savings through automation that eliminates time-consuming manual processes as well as easing traditionally complex change management, storage configuration and capacity planning tasks.

Pricing and Availability VMware Virtual SAN is now generally available. VMware Virtual SAN is priced at $2,495 per processor. VMware Virtual SAN for Desktop is priced at $50 per user.
  • For a limited time, customers can purchase a bundle of VMware Virtual SAN with VMware vSphere Data Protection Advanced for $2,875 per processor. 
  • For a limited time, VMware vSphere Storage Appliance customers will be able to upgrade to VMware Virtual SAN at 20 percent off the list price.

The state of the VDI industry in 2014

After consulting and writing about desktop virtualisation for 17 years, since Citrix WinFrame, for the past eight of those years, I’ve been repeatedly answering the question, “Is this the year of VDI?”
The answer this time, surprisingly, is quite possibly “yes!” But first a little background.
virtual-desktop-290px.jpg
FLYDRAGON - FOTOLIA
In 2012 I co-authored a book called The VDI Delusion. As you can guess from the title, I wasn’t exactly hot on VDI (virtual desktop infrastructure) at the time. The main problem back then was that VDI was being sold as a cheaper, more secure, and more manageable version of traditional Windows desktops. Unfortunately the lengths that customers had to go to in order to realise those benefits were extreme.
For example, people selling VDI claimed it was more manageable because multiple users could share a single desktop, via something called “desktop pooling” or “non-persistent images”.
The problem is that traditional Windows desktop and laptop environments don’t work this way, so if you want to convert from persistent traditional desktops to non-persistent VDI desktops, you have a lot of pain ahead of you. You have to try things like application virtualisation and user profile management and pool management and layering and all sorts of other things, all of which don’t work 100% and lead you to a failed environment that isn’t as flexible as what you had before VDI.

Security

The same could be said about security. Sure, VDI desktops can theoretically be more secure than traditional desktops, but let’s face it - VDI is still about human users running Windows applications.
Today’s security nightmares are not about stolen laptops - enterprise disk encryption software is a lot cheaper and easier to implement than VDI - rather, security folks worry about zero-day attacks and viruses and malware. Well guess what? That all exists in VDI too! Again, I’m not saying that you can’t make a VDI environment that’s more secure than a traditional environment - rather, I’m just saying that if you choose VDI, you don’t get a free pass at security.
These reasons, combined with the fact that designing VDI systems is enormously complex, are why VDI has only enjoyed a 1%-3% adoption rate so far.
But now that it’s 2014, what does the VDI market look like?

Technology advancements

First of all, there were two major technological advancements, which came out in 2013, that are making VDI much more attractive in many scenarios.
The first is an advancement in storage technologies.
When VDI first came out, the reason everyone tried to use the non-persistent pooled desktop approach is because the performance needed to give every user his or her own unique desktop disk image was flat-out too expensive.
You would have had to spend £500 or more per user just on the storage, and that would have broken any cost model you had to justify VDI. But today’s storage vendors have technologies like in-line block-level single-instance storage - or “block-level deduplication” - that enable you to offer high-performance fully persistent disk images for somewhere in the neighborhood of £50 per user.
VDI is not a silver bullet, but you could be pleasantly surprised at what you find
This means you can design and manage your VDI desktops in the same way you’ve been designing your traditional desktops for the past two decades. In other words, you can design VDI in a way that actually works in your environment.
The other major improvement to VDI in 2013 was around graphics. Desktop computers and laptops have had graphical processor units (GPUs) for years. Everything a user does - from Alt-Tab’ing through applications to surfing the web to video chatting - requires a GPU. Unfortunately hypervisors such as VMware vSphere and Microsoft Hyper-V have not traditionally virtualised GPUs, so even if you had them installed in your VDI servers, your VDI desktops did not know they were there.
That changed in 2013. Led by Nvidia with its Grid technology, we now have full GPU support in VDI desktops with products like Citrix XenDesktop and VMware Horizon View when running on the latest hypervisors. This means VDI users can now do everything in their remote VDI desktops that they could do in their traditional desktops and laptops.
These two technological advances, combined with Moore’s Law continuously driving down the cost of server hardware, mean that VDI is an option for millions more users than it previously had been.

Larger deployments

You can see proof of this every day. From 2006-2013, I could count the number of large (more than 10,000 seat) VDI deployments on one hand. But thanks to these improvements, I’ve seen more large VDI deployments in the past three months than in the past eight years combined.
To be clear, this does not mean that VDI is right for everyone or that VDI is the sole future of the enterprise Windows desktop. It simply means that VDI is a viable option for more users than ever before.
So is VDI right for you? That depends. The most important thing to understand is that VDI is not an “all-or-nothing” play. VDI is nothing more than a form factor option. Some of your Windows desktops will run on desktop computers, some on laptops, and some on VDI. Each has its advantages and disadvantages.
VDI is not a silver bullet. No matter how good VDI gets, using a Microsoft Windows desktop interface that was designed for a large screen, a keyboard, and a mouse, will always be clunky from an iPad. But if you haven’t looked at VDI in a while, take a look again with the latest technologies—you could be pleasantly surprised at what you find.
Brian Madden is editor of BrianMadden.com and an internationally recognised expert on desktop virtualisation.
If you’re interesting in digging deeper into VDI, Brian is hosting a forthcoming conference called “BriForum” in London from 20-21 May, 2014. BriForum is a vendor-neutral, highly technical conference dedicated to end-user computing technologies like VDI. This is the event’s fourth year in London, and will be attended by hundreds of geeks who will share their stories and lessons learned with VDI projects.
