  Desktop as a Service (DaaS)

  VDA (Virtual Desktop Access)

  Windows Virtual Desktop Access (VDA) is an authorization strategy that requires each device seeking access to a virtual desktop in a Microsoft Virtual Desktop Infrastructure (VDI) to be licensed.   Read Now

1Evaluating virtual desktop delivery methods

The principle of cloud desktops has been around for more than 10 years, but it's only just begun to gain a foothold in terms of adoption. That could be because IT shops are interested in VDI but can't front the money for it, or because the cloud is just a hot-button topic these days. Either way, many people don't know the details of DaaS technology or how it compares to VDI. Start here for the basics on how it works, how it's different from VDI and why the comparisons aren't necessarily fair.

  It's so new, IT can't keep up

  VDI has seen pretty slow adoption -- some experts think it will never crack 20% -- so what does that say about how quickly organizations will adopt cloud desktops? There are tons of options out there now, and they'll just improve over time.  Read Now

  If your VDI pilot failed, look to DaaS

  Many companies try to get VDI off the ground but find that it's too expensive or that users reject it. Especially in small companies where VDI is often cost prohibitive, DaaS can be a great option because you're taking advantage of infrastructure someone else already built and has pledged to maintain. Read Now

  DaaS doesn't fall far from the VDI tree

  It might seem like DaaS and VDI are very different, but the two share a lot of the same benefits, including easier desktop management, more flexibility and mobility, and less hardware. They also both come with licensing complexity. But of the two, only DaaS brings cloud security concerns. Read Now

  Predictable cost, scalability make cloud desktops IT's sweetheart

  For many VDI projects, costs can balloon down the line, and the infrastructure is hard to scale up and down on your own. But with a subscription-based, cloud-centric model, costs are predictable over the long term, and you can scale quickly in either direction if you need to. And with DaaS, it can be easier to set up a pilot program. Read Now

  The DaaS vs. VDI talk isn't fair

  The DaaS cost models that vendors such as Amazon push are flawed. When you compare the highest-priced VDI software with all the bells and whistles to the lowest-priced DaaS setup based on Server images, of course DaaS is going to look cheaper. But you can't compare Windows 7 to Windows Server. They're just not the same thing. Read Now

2Technical details

DaaS can be confusing. For example, did you know that some application delivery techniques are technically DaaS? And there's a big difference between hosting Windows Server images in the cloud and hosting desktops. Don't forget about the potential licensing costs and complexity that can come with DaaS -- they mean that sometimes cloud desktops won't save money over VDI. Sink your teeth into all these topics and more.

  Apps from the cloud are DaaS

  If you host applications in the cloud so you can deliver them to users, that's technically considered DaaS. Why? Because applications need a desktop OS in order to run. Even in the cloud, the apps are running on a desktop, but when it gets to users, the desktop is invisible. Read Now

  DaaS dollars and sense

  When you're looking at deploying cloud desktops, consider how much it's going to cost you and which providers and platforms fit your use case. As more options enter the DaaS fold, it's only natural that competition will affect prices.  Read Now

  Savings are subjective

  Depending on which provider and platform you settle on, deploying cloud desktops may not save money over VDI in the long run. Management costs -- because you still need to maintain and update images, applications, security and the network -- subscription fees and hardware requirements all play into how much cash stays in the company kitty. Read Now

  You're still on the hook for licensing

  With hosted desktops, you have to license the Windows OSes, the desktop virtualization software and the endpoint devices. Additionally, every DaaS vendor and service provider handles licensing in its own way. Some providers need you to bring your own Virtual Desktop Access licenses. Read Now

  Why Microsoft licensing complicates doing "true" DaaS

  Windows desktop OS licensing restrictions make it really hard for companies to do "real" DaaS. Instead, DaaS vendors such as Amazon and VMware skin Windows Server 2008 R2 images to look like Windows. It works and customers want it, but it's not a true desktop. Read Now

  Windows Server images just aren't as good

  Hosted virtual desktops that are based on Windows Server images have more horsepower and resources, and customers can assign multiple CPUs to power the desktops. But there are desktop- and application-compatibility problems that come with using server rather than desktop images Read Now

3Choosing a DaaS provider

Just like some rectangles are squares, some DaaS providers are platforms -- but not all platforms are providers, and not all providers are platforms. If that's got your head spinning, don't fret. There are ways to find the right provider and platform for you, but you'll have to take charge. Make sure you ask the right questions and negotiate a service-level agreement (SLA) that sways in your favor.

  DaaS providers and platforms: When a rectangle is a square

  In the DaaS market, there are many providers, but not as many platforms. The platform is what cloud desktops run on, and providers are the companies you buy that service from. For example, VMware has a platform and is a provider, but if you want to host desktops on tuCloud infrastructure, you'll need to talk to a provider that has a relationship with that platform. Read Now

  Five questions to take on DaaS provider speed dates

  Before you pick a DaaS provider, it's important to ask questions about what would happen in the event of an outage, how the provider splits up resources among virtual desktops and what happens to user profiles. Read Now

  What you can expect from DaaS providers

  Not all DaaS providers are created equal. Some vendors and platforms might not support the clients, OSes or applications you need. Management consoles and capabilities also differ from one product to the next. The provider you choose should have an SLA that outlines how the company will handle security breaches and outages. Read Now

  Why Amazon WorkSpaces is unique

  With Amazon WorkSpaces, customers can pay by the desktop, or by the month. Amazon can afford to offer that because it has such a huge presence in the cloud market. While other DaaS providers might need to add server, storage and network hardware to bring in more customers, Amazon already has all that.  Read Now
