postheadericon T1R: Peak 10 is banking on hybrid cloud implementation

“The diverse needs of enterprises suggest that there is no single IT approach that could possibly resolve all IT pain points within a company. While IT executives are in the stage of combining their operational practices with innovation, they realize that any new technology deployment involves a change in business process and management. And IT transformation could be a costly endeavor if it isn't done right from day one. As a result, many CIOs are taking a pragmatic approach, embracing new technologies that would enable them to keep ahead of technological obsolescence without disrupting the existing business process and management imperatives. This sort of operational balance is well received by a lot of enterprises that are looking for technology extension, not replacement.

Peak 10's hybrid cloud strategy

In the context of cloud computing, not surprisingly, the notion of deploying a hybrid cloud that connects traditional enterprise IT infrastructure with the next generation cloud computing platform (both public and private) is growing in popularity in the marketplace. Peak 10, a managed services provider that offers managed hosting services in both physical and virtual environments for SMBs and mid-sized enterprises, has made noticeable efforts to bring the hybrid approach into fruition. Aside from adding a multi-tenant enterprise cloud service to complement its existing private cloud offering, Peak 10 has focused on demonstrating the unique capability of its 'Cloud Plus' platform. As its name suggested, the 'plus' component is to emphasize Peak 10's ability to support a hybrid approach that many customers are asking for. Thus, using 'Cloud Plus' offerings (both multi-tenant enterprise cloud and private cloud), customers are able to seamlessly interconnect existing IT infrastructures hosted in Peak 10's datacenter facilities with Peak 10's clouds.

Tier 1 believes this is a sensible approach to increase the stickiness of enterprise customers while driving cloud migration based on individual requirements and timetables. Pure Fishing is a textbook example of how existing managed hosting customers embrace Peak 10's Cloud Plus offering as part of the company's IT transformation initiatives. However, this approach does rely heavily on technology partners and consultants to bridge the gaps in extending business functionalities across multiple operational environments. Not surprisingly, Peak 10's product team is deeply involved in the service provisioning for the initial cloud deployment and manages seamless integration between cloud services and managed services.

What is in Enterprise Cloud Plus?

Enterprise Cloud Plus service is a multi-tenant offering that delivers cloud computing with dynamic load sharing and seamless scaling. It also supports cloud bursting for demand spikes while running specific workloads. The enterprise cloud is being supported by multi-datacenter clusters out of Peak 10's 19 datacenter facilities and it is accessible via the public Internet and private network (both VPN/IP Sec VPN and private line connectivity). In terms of pricing, Peak 10's enterprise cloud is not the typical 'pay as you go' utility-based consumption model, although it is moving customers from a capex to opex model. The contract-based pricing with minimum commitment suggests that Peak 10 is putting its bet on niche enterprise segments where customers are familiar with usage patterns of their existing workloads and are willing to outsource specific workloads (typically non mission-critical workloads) to a cloud partner for operational efficiency. Peak 10's cloud service customers include companies in the health care, gaming and technology verticals. With more managed hosting customers coming to the end of their business lifecycle, Peak 10 expects to see a surge in demand from existing managed hosting clients.

T1R take

Peak 10 fares well in its cloud offerings by being able to demonstrate a high degree of service flexibility and manageability. To try and differ from many of its peers in the managed hosting space, Peak 10 implements a high-touch approach to grow contract value from existing enterprise customers. Although the uptake is picking up, Peak 10 has plenty of room for growth. Going forward, Peak 10 needs to be cognizant when implementing its high-touch service approach as the barriers to entry in this arena are relatively low and an adroit newcomer can offer just the right mix of price, quality and service component to entice business customers. The notion of delivering 'consulting as-a-service' with no strings attached is coming of age in the industry. And the unspoken truth is that service value lies in the eyes of the beholders. For SMBs, the availability of procurement options could be convincing enough to get buy-in.

Boosting IT innovation is more an operational challenge than a technology barrier. Many of the IT projects fail to deliver on their promise because enterprise users are reluctant to make a change based on both rational and irrational factors such as insufficient training and the workplace complacency syndrome. The human factor is hard to ignore. And cloud players must play a proactive role in facilitating innovation efforts that can benefit all parties within the company's IT ecosystem.”

postheadericon How to Negotiate a Better Cloud Computing Contract

“Standard cloud computing contracts are one-sided documents that impose responsibility for security and data protection on the customer, disclaim all liability, offer no warranties, and give the vendor the right to suspend service at will. So why would you bother to sign on the dotted line?”

 

This statement identifies the differentiation metric for Cloud services: Service Level Agreements.  No person, no department, no business functions without them.  We do best when they are explicit and negotiated at the start of service delivery, but rest assured you are responsible for a certain service level whether you’ve been told it explicitly or not.

“An engine nozzle turns a dramatic array of colors during a recent hot-fire test at NASA's White Sands Test Facility near Las Cruces, N.M. A team of engineers from Glenn Research Center in Cleveland, Ohio, Marshall Space Flight Center in Huntsville, Ala., and Johnson Space Center in Houston conducted tests on a cryogenic liquid oxygen and liquid methane engine to measure the engine’s performance for future use with in-space vehicles.

 

Last month, eight altitude chamber tests were performed using an Aerojet workhorse engine to gather design data for future lander and in-space engines. Using the altitude chamber, which simulates the space-type vacuum environment, engineers were able to attach a larger nozzle and vary the propellant mixture ratios to test the engine's overall operating capability. This technology could be selected for future use with vehicles designed for transport, descent, or ascent to another planetary body or asteroid.”

postheadericon VDI versus Server-Based Computing (SBC), Part 2

What technology makes VDI possible?

Now that we’ve looked at what VDI is and where is can be used, let’s roll up our sleeves and look at the underlying technology that makes VDI possible. At the most basic level you need a few things.


<>     a) A mechanism to run many Windows desktops in your datacenter
<>     b) A method for your users to remotely find and connect to those Windows desktops in the datacenter

How to get Desktops in the Datacenter

The first part of a VDI solution involves getting your users’ workstations running in your datacenter. As I briefly mentioned previously in this article, there are several ways to run lots and lots of Windows workstations in your datacenter.

You could:
<>         i.   Buy individual Windows desktop machines and stack them floor-to-ceiling in your datacenter
            Buy server blades and install a copy of Windows  on each blade
           Use VMware or Microsoft Virtual Server and build huge servers that each run many VMs

A full analysis of the pros and cons of each of these three techniques is beyond the scope of this article. Needless to say, the VM-based solution usually “wins” for most people because it’s the most cost-effective.

Key Features and Capabilities

Simplified Desktop Management
Automated Desktop Provisioning
Template/Master Image Deployment
Availability and Scalability

From a central management console you can deliver, manage and update all of your Windows desktops quickly.

Automated Desktop Provisioning. Provision new desktops or groups of desktops, with a simple mechanism for standardizing desktop policies. As with virtual server provisioning, templates can be used for desktop creation.

Template/Master Image Deployment.  VDI platforms enable rapid creation of desktop images from a golden, master image. Whatever updates are implemented on the parent image can be pushed out to any number of virtual desktops quickly, simplifying deployment and patches and reducing costs. These processes do not necessarily affect user settings, data or applications, so the user remains productive on a working desktop, even while the changes are being applied.

Availability and Scalability. The same High-availability technologies and resource provisioning technologies deployed at the server level applies at the desktop level.

Conclusions

VDI and sister, SBC, are certainly not the silver-bullet for desktop provisioning and management, but they are indicative of the pervasiveness which the hypervisor/virtualization concept continues to abstract the OS and applications from the underlying hardware which supports the various workloads organizations – and specifically IT engineers and operators – need to continue to manage.

postheadericon VDI versus Server-Based Computing (SBC), Part 1

With the advent of Cloud Computing, the IT industry began making promises that 2009 would be “the year of VDI”.  So here we are in 2010 and as the major hypervisor makers are working diligently to thrust themselves into the desktop marketplace (significantly larger than the server market; VMware, Citrix), I thought it was a good opportunity to lay out a few concepts to frame the discussion of VDI.

At the most basic level, VDI technology is a new method for delivering desktops to users.  Of course users have been using desktops for years, at first running locally on their own PCs, and more recently by accessing remote server-based computing (SBC) desktops running on Microsoft terminal servers or Citrix Presentation Servers. 

Now that various VDI technologies have hit the market, reactions are all over the place.  Some people are talking about how VDI will replace or compete with SBC and traditional technologies.  It is fair to say that there is some overlap between the technologies and therefore some cannibalization is to be e7ected, but the use-cases for each technology is distinct and proper application can mean the difference between success and failure.

What is VDI?

The idea is simple. Instead of giving a user a local PC running a local copy of Windows 7, you run the Windows 7 (or Vista) desktop software in your datacenter. Then your users remotely connect to and control their own instance of their Windows desktop in a one-to-one manner from their own client device.

In doing so, the user can use any client device they want to access “their desktop.” If you replace a user’s desktop with a thin client that automatically connects to a Windows machine in the datacenter when the client is powered on, there’s a good chance that the user wouldn’t even know they were using a remote desktop.

In reality, no one would implement this by stacking Windows 7 desktop computers floor-to-ceiling in their datacenter. Instead, VDI is typically implemented by building huge VMware servers running many Windows 7 VMs or by using high-density blade servers running Windows 7.

Why use VDI?

So why would anyone do this? To understand it, we first have to look at the alternatives. The role of an IT department is to provide applications for users. In order to use an application, a user needs a desktop. (Be it a Windows desktop, a browser window, or something else, there has to be a backdrop that has some method for users to select and launch applications.)

VDI is about providing desktops to users. Before VDI, there were two other ways to provide desktops to users:
a)      The old way, with each user running a local copy of Windows 7 on their own local desktop or laptop computer. (Hereinafter “local desktop”)
b)      The server-based computing (SBC) way, with each user connecting to a remote desktop session running on a Microsoft terminal server and/or a Citrix Presentation Server. (Hereinafter “SBC desktop”)

The VDI approach adds a third option to this mix. Therefore in order to answer the question of why anyone would want to use the VDI option, we have to look at how the VDI option “competes” against a local desktop or SBC desktop solution.
VDI versus local desktops

When comparing VDI to a local desktop solution, you’ll see that the VDI option lets the users enjoy many of the benefits of traditional local desktops while also adding some new benefits.

VDI advantages over local desktops

         i.            Data containment
       ii.            Desktops are running on server-class hardware
      iii.            Client device independence
     iv.            Ease of management

Data containment. Since a VDI solution means that users’ desktops are running on servers in a datacenter, the C: drive of each desktop is also running in that datacenter. That means that all data is automatically contained within the walls of the datacenter.

Desktops run on server-class hardware. Since desktop computers are distributed throughout an organization, they don’t have the same redundancy as server-class hardware. A single power supply, drive, or memory failure can take down a desktop computer. Of course the same also applies to servers. However, since there are many fewer servers in an organization than desktops, it’s okay from a financial and risk standpoint to spend money on redundant power, RAID, memory, and other technologies to ensure that server hardware doesn’t have the same potential hardware failures.

Client device independence. In a VDI environment, the ultimate “client” device is essentially nothing more than a screen, a mouse, a keyboard, and some mechanism (RDP, ICA, etc.) for connecting to remote Windows 7 desktops. This means that the client device can be just about anything—a thin client, a Mac, a laptop, or a UNIX workstation.

Ease of management. If you have to manage 1000 desktops, which would you rather manage: 1000 physical desktops scattered all over the place, or 1000 desktops contained in a single datacenter? The simple fact that the client “workstations” are all in the datacenter can have a profound effect on management, patching, backups, provisioning, etc.
Local desktop advantages over VDI desktops

Of course VDI is not for everyone, and certainly there are a several advantages that the “traditional” local desktop model has over VDI architectures.
Local desktops can be used offline (i.e. laptops)

No single points of failure

Local desktops can be used offline. This is probably one of the biggest downsides to VDI. In a VDI environment with everything running in the datacenter, if the network link goes down between the client device and the datacenter, or if the user wants to be mobile with a laptop, then the whole VDI concept breaks down.

It's worth noting that there are some novel solutions to this. For example, you could install VMware on a laptop and then copy the user’s VMware disk image from the datacenter to that laptop for them to use on the road, but that introduces its own challenges that are beyond the scope of this article.

Local desktops to not have a single point of failure. Even though server hardware is very redundant, if something happens to your back-end servers in a VDI environment, you’re totally out of luck. Compare that to a traditional desktop environment. If one PC fails, that user is out of luck, but the other users can still work.
VDI versus SBC desktops

The other option for providing desktops to users is via server-based computing. This is kind of interesting now because in many ways this was the first VDI solution, and it’s been in place for over ten years. In fact, Citrix didn’t even introduce seamless application publishing until 1999, so anything “SBC” before that was full remote desktops. Of course we didn’t know to call it “VDI” back then, but that’s what it was.

However, today’s Windows 7-based VDI is very different than today’s terminal server / Citrix-based desktop publishing, even though they both fundamentally solve the same business goal (desktops to users).

Let’s compare these two technologies and look at where each has an edge.

VDI advantages over SBC desktops

Better performance (from the users’ standpoint)
No application compatibility issues
Better / easier security
You can "suspend" individual VMs and then move them from server to server
The clients run the "workstation" version of software
Users have more control over their individual desktop
Users can take their sessions with them when they go offline
Easier backups

Better performance. (In theory, anyway.) Any performance gains might depend on whether your VDI Windows 7 desktop backend is made up of blades or regular servers running VMware. Obviously if you only have one user (or a handful of users) on each blade, then your users can run bigger and more powerful applications without negatively affecting as many users as in a terminal server environment. If you're using VM software to cut a huge server into dozens of Windows 7 VMs, then you will have the ability to partition the resources for each VM in a different way than regular terminal server or Citrix SBC sessions.

No application compatibility issues. With VDI, each backend Windows 7 desktop is a full standalone workstation. This means that you don't have to worry about applications that are not terminal services-compatible.

Better / easier security. Since each user would have his own standalone Windows 7 desktop, you don’t have to worry as much about locking down each user's session. If a user screws something up, he won't affect other users.

You can "suspend" individual VMs and then move them from server to server. If your backend Windows 7 VDI infrastructure was based on VMware, you could have some cool flexibility for doing maintenance. Imagine a scenario where you could hit a button in a management console to "move" a user to another server. Maybe the user would receive a popup box that said "Please wait a moment." Then the server would dump the memory contents of the Windows 7 desktop VM to a disk, a VM would be provisioned on another physical piece of hardware, and the VM would be brought back online. This whole process would probably take less than 30 seconds and the user would pick up right where they left off. Another use of this technology would be that you could have an additional "timeout" setting. For example, maybe after 20 minutes of no activity a user's session would be disconnected (where it is still running on the server, but disconnected from the client). If the user still didn't connect back to it after an hour, the system could "suspend" the session by dumping the memory contents to disk and then free up the hardware for someone else. Whenever the user decided to connect back in, the session would be re-hydrated and the user would pick up right where they left off—regardless of how long it had been.

The clients run the "workstation" version of software. Since these VDI desktops would be based on Windows 7 instead of Windows Server sessions, any software or applications would see the sessions as real workstations. You could use workstation versions of all your software.

Users have more control over their individual desktop. Again, since each user would get a full Windows 7 workstation, they can customize it however they want (or as much as you let them). But as the administrator, you can be more flexible about what you let your users do since you don't have to worry about them screwing up other users.

Users can take their sessions with them when they go offline. If your backend VDI infrastructure is based on VM desktops, you can do cool things since the VM software provides a view of the hardware to users no matter what the physical hardware looks like. So in an environment where all users' desktops are provided to them as VMs, they could use centralized backend servers when they are in the office and then use laptops running VMware when they hit the road and need to run offline. There could be a one-button "take offline" option that suspends the user's session and then copies down the disk image and memory space to the laptop where it could be resumed. You could even have generic laptops that users could "check out" when traveling. Imagine VMware ACE with the flexibility of running remotely or locally, and easily switching back and forth.

Easier backups. For VM-based VDI solutions, all you would have to do is to backup the disk image files for all the user's workstations. Then if a user lost something it would be simple to "roll back" their laptop to whenever they wanted. You could even take this a step further and provide an automatic snap-shotting service that did this once an hour.

After reading through this list, you can see that VDI is cool. It combines the benefits of distributed desktops with the benefits of server-based computing. But there’s a flip side. You also get a lot of disadvantages of distributed desktops.

SBC desktop advantages over VDI desktops

You don’t have to manage a whole bunch of desktops
Less server hardware is required.
The software is more mature

Management. One of the original beauties of SBC is that you can run probably 50 or 75 desktop sessions on a single terminal server or Citrix Presentation Server, and that server has one instance of Windows to manage. When you go VDI, your 50 to 75 users have 50 to 75 copies of Windows 7 that you need to configure, manage, patch, clean, update, and disinfect. Bummer!

Less server hardware is required. Giving each user a full workstation VM or blade will require more computing resources than simply giving them a session on a terminal server. A dual processor server with 4GB of RAM can probably run 50-100 desktop sessions as a terminal server. With VMware, you're probably only looking at 15-20 Windows 7 VMs.

Less software is required. In addition to your OS and application software, with VDI you'll also need the hypervisor software (from VMware or Microsoft) and you'll need some software to manage the provisioning of VMs for users. Of course this will also cost more money.

When does VDI make sense?

Given these comparisons, should you use VDI technology in your environment? Hopefully it’s obvious that any environment can benefit from a blended approach. Just as it makes sense to build a comprehensive application delivery solution that involves server-based computing, traditionally installed applications, and application streaming, you should think about the desktop as “just another application” that can be delivered in many ways depending on the situation.

The over-hyped example that’s always used to answer the question of “why would someone need VDI” is for remote software developers. The idea is that the remote developers can each have their own VM or bladed desktop and do whatever they want to it without affecting other users.

While I definitely think this use case is a good example, the problem is that VDI is also useful in many other ways. My fear is that always using the developer example will lead people to think that they don’t need VDI if they don’t have any remote developers.

The reality is that VDI technology is useful in any scenario where you have power users or users who need strange, non-terminal-server-compatible applications, but where the users still need the flexibility associated with traditional SBC environments. (Connecting to applications from anywhere, over slow connections, etc.)

VDI will be useful just about everywhere, albeit in a limited way. It will just be one of the multiple methods that can be used to provide a desktop to a user.

My view is VDI can play a role in nearly 100% of all companies out there, but only for probably 20-40% of user types at those companies.  So yes, it’s useful, but no, no one is throwing out their SBC environments or desktop computers.

Speaking at a conference held by French telecoms regulator Arcep on Tuesday, Kroes said the internet was "not an inherently neutral platform". This means that European regulators have to make choices about whether to allow ISPs to prioritise certain types of online traffic, she added.”

At this point, it's fair to say that most IT execs are wary of entrusting sensitive data or important applications to the public cloud.”

If you're basing your existing disaster recovery plans around tapes that you're shipping back and forth between your local sites and one or more offsite storage facilities, then you already know that using tapes for recovery leads to days' worth of data loss, recovery times that can take from days to weeks, and recovery reliability issues that (for whatever reason) mean you can't always get back the data you need.”

 

Interesting product.  I wonder if it works.  I’ll do some more investigation..
