What is the Cloud Desktop Fabric Architecture for Cloud VDI?

A Rough Road for Legacy VDI

In the early days of VDI, the promise of its simplicity, security, and reliability benefits was alluring.   Virtualize and centralize the Windows desktop in the data center. Any user can use any device to securely access their business applications from anywhere in the world. Of course, the reality was quite different. Year after year we heard the question asked: “Is this the year of VDI?” Despite the hype, it just never became mainstream, and the reasons are pretty clear. The legacy VDI stack is enormously challenging for IT teams. A cross-functional team of server, storage, desktop, networking and security engineers could spend months designing and implementing a complex solution stack. Yet, despite all these valuable resources weighing in, inevitably there are issues with availability. When something breaks and users cannot reach their desktops, it becomes a multi-dimensional problem to try to determine the root cause of the outage. If complex implementation and troubleshooting aren’t enough, to top it off, end-users typically experience poor performance. Business leaders end up unhappy because it takes so long (if ever) to realize any value, and it turns out that despite claims to the contrary, these legacy solutions are too rigid to scale and keep up with the dynamics of the business.

It has been a rough road for VDI and especially for the organizations that have struggled with their implementations. The complex, do-it-yourself (DIY) model, using a solution stack built for a single customer in a single data center, is no longer relevant in the cloud era. What’s readily doable today goes leaps and bounds beyond the promises of legacy VDI to deliver real business value – fast. Here’s how.

Cloud VDI in the Fast Lane

So, if you take a look at the VDI stack in terms of capabilities, there are three broad areas to examine – infrastructure (servers, storage, and virtualization), legacy VDI software and finally, the integration & operations needed to run the solution. Even though a lot of attention is often focused on the legacy VDI software stack, the overall solution cost & complexity stems primarily from the integration and ongoing operation of the VDI stack.

Workspot Cloud VDI is the first VDI solution built for the public cloud era. It’s turnkey SaaS for VDI. Because we deliver most of the VDI solution stack as a turnkey service, you don’t have to deal with any of the complexity anymore. We do it for you. Plus, it’s important to note that we invented cloud-native VDI; we are not just running someone else’s technology. The close partnerships we have with our customers are enabled by a very short feedback loop. Your pilot can be up and running in days, and your production rollout live in 30-90 days, depending on the complexity of your enterprise requirements. Our Go-Live Deployment Services cover helping you roll out your first production use case to the first set of users. As a company, we are focused on your business success, because that’s the only way we can all be successful. So we include the services needed to take you live into the cost of your subscription fee. Our solution is priced at a flat rate per user – the rate depends on the configurations you choose for your cloud desktops and workstations. Finally, we take full responsibility for the SLA of your virtual desktops – all the elements in the blue box in the picture below, including the availability of the public cloud. Imagine what you can do with all those IT resources you can free up!

Now, inventing cloud-native VDI is a tough problem, because a true SaaS service has to be multi-tenant and turnkey, and this necessitates building the solution from scratch. Legacy, single-tenant, DIY, on-premises architectures cannot be evolved into a cloud-native SaaS service. Multiple legacy software vendors have tried and failed with this approach – witness Siebel, BMC, Peoplesoft and others.

You can build a great cloud-native service in one data center. But the public cloud adds another strategically important dimension which is at the crux of realizing business value: the ability to take advantage of the edge of the cloud.

A New Architecture is Required for Edge of the Cloud Benefits

If you look at all legacy software stacks – databases, app servers, and VDI – they were built for a single data center, and with great difficulty and a ton of IT resources, customers operated them in 2-3 data centers. Often this was done with replicated instances and management. The public cloud offers each customer the ability to run software in tens of cloud regions worldwide – essentially you have tens of data centers available to you. These cloud regions are also connected using the best, fastest, most reliable networks. A completely new, built-from-the-ground-up architecture was needed to take advantage of the power of the edge of the cloud because you simply cannot install and operate 50 copies of everything and hope to succeed. So, that’s what we built; a cloud-native, globally distributed architecture that allows you to scale horizontally across cloud regions – in minutes. That is a massive innovation in the VDI space that is fundamentally transforming how companies do business and how they grow.

The Power of the Cloud Edge

 

The Cloud Desktop Fabric – Only from Workspot

The diagram below illustrates what’s possible as enterprise organizations take advantage of cloud-scale VDI. The first layer at the bottom of the fabric is the public cloud. Super powerful, but also super complex. To implement DIY cloud desktops, you’d have to deal with compute, storage, networking, and images in each region. Your costs will vary in each region, and they will add up to what could be an unpleasant surprise.

First and foremost, Workspot’s mission is to alleviate VDI complexity and reduce the costs of operating virtual desktops, so we built an elastic, Global Desktop Fabric(TM) that abstracts and simplifies the public cloud for virtual desktop use cases. This is the second layer, just above the public cloud. Among the 54 Azure cloud regions (a.k.a. your new data centers!) you have available worldwide, you simply select the regions closest to your users, then select your turnkey desktop configurations – how many CPUs, how much memory, and how much storage for each. Then, you leave the rest to us! It’s our job to deliver on the SLA of the cloud desktops globally and make sure we manage the costs so we can provide to you a single, flat rate per desktop.

The third layer is all about your use cases, and mapping the unique requirements of each to the type of cloud desktop best suited for each use case.  You might want persistent Windows 10 desktops for your developers and CAD designers. You might want non-persistent Windows 10 desktops or Windows application access for your call center agents; some users need GPUs, some don’t. And so on…

Finally, the top layer represents the users. Even though they are distributed across the globe, they experience great performance because their desktops and data are located in the nearest cloud region. When was the last time you heard that VDI performance is better than a local desktop or workstation? Never? We hear this every day!

Workspot Built a Cloud Desktop Fabric

It’s really important to note that Workspot helps IT manage all the layers – cloud, fabric, use cases, and users –  through a single pane of glass. No one else can do this.

The fabric has obvious benefits for creating a global, virtual desktop footprint, including fast time to value and great performance for your users, but those benefits are just the beginning.  For example, the elastic nature of the fabric reduces end-user desktop provisioning time dramatically, especially when integrated with your favorite IT service catalog. Also, deep instrumentation embedded in every layer of the stack allows for intelligent, real-time root cause and blast radius analysis – on a global scale – to meet the most demanding SLAs.
