Droplet Computing Product Walk Thru: Not just another Droplet in the ocean

NOTE: Okay, I fess up that shameless nod to one of my favourite bands of the 80’s the indomitable “Echo and The Bunnymen” and their ‘hit’ “The Cutter”. What can I say I spent the later part of the 80s dressed in black moaning about how terrible life was… But hey, didn’t we all do that as teenagers?


This blogpost represents a walk thru the Droplet Computing container application and will attempt to describe the technology whilst keeping eyes focused on the practical side of life. I think I have one more Droplet Computing blogpost in me, and that post will be about where I think the next iteration of features should take them, and some of the challenges around achieving that. There are plenty of other things I want to learn about Droplet Computing, not least the process of authoring .droplet image files. So, whilst this blog does cover some very modest “administrator” like functions, it’s still very much focused on the “user experience” rather getting into much of the weeds of management.

Being a Mac user, I was supplied with the OS X version of Droplet – but a Windows and Linux version exists. The main thing to say is the functionality is the same regardless of device type, and the image file that makes up the environment in which applications work is portable between three support device types. Remember, Droplet Computing is container-based technology, it’s not a virtual machine or application virtualization. Apps are installed “as is” without any special packaging or sequencing process. And I think this will appeal to customers who do not have the time or resources for a dedicated team of packaging experts.

In the Apple Mac system images are moved from the location from which they were downloaded to this path:

/Users/<username>/Library/Application Support/Droplet/Images

These .droplet image files basically holds the Container OS files, I’m my case Windows XP together with any applications that have been pre-installed there. Droplet Computing provided me with the .zip file that contain both the core application and the image. When starting Droplet Computing for the first time you’re asked for the .droplet file, and if required it will move it to the images path.  Currently, it’s Droplet Computing that provide the base .droplet file from which you can make multiple copies, and install software using the usual methods.

[Technical Bit: Early versions of Droplet Computing used a web-browser such as Google Chrome to provide the runtime environment. This approach has been dropped for the moment, as Google were pushing too many updates to Chrome to make this a reliable process that didn’t trigger endless regression testing. Droplet Computing has adopted a Chromium web-browser which they control to side step this issue. Needless to say, that the end-user never sees this hidden web-browser.]

Start and Load a Droplet Computing Container/Application

When Droplet Computing is loaded for the first time, the user has access to locate their image file, and there’s an option to control how much memory is assigned to the container, as well as set the location of their “Shared Folder”. This allows for the easy transfer of small files to and from the host and the Droplet Computing Container. Personally, I didn’t use this shared folder feature – opting instead to connect the Container OS to my home NAS server, and find my software there.

I’ve an old 13” MacBook Pro with 8GB of RAM and SSD drive which is circa 2012. So, it’s by no means a powerful machine by modern standards (it suits my needs perfectly fine until it stops working!). Clicking the big orange “Start Container” erm, starts the container…. That process took on my machine about 1min and 30seconds which I don’t think is too shabby considering the hardware involved, and the start-up time compares very favourably to a locally run virtual machine using VMware Fusion or Virtualbox.

Note: Currently this progress bar, really only shows that the container is loading, it doesn’t really show how far complete the process is.

To make my life easier, Droplet Computing has pre-set-up an application as part of my sample image that was notepad. A simple “launch” button option loads the application from within the container.

Note: Ordinary users can remove application tiles from this UI at will.

Shutting down an application is the same in the container as it would be in Windows XP. Clicking the red X in the top right-hand corner will close the app or using File, Exit. It’s the container OS’s job to check that files have been saved, and if the users chose to save some data, then it currently defaults to the user profile settings. In the world of a generic unmodified Windows XP installation, this is the “My Documents” folder. (Gee, remember when every folder in a Windows install had the word My appended to it for no apparent useful reason!). One thing that’s worth noting is that currently it is possible to shut down the container and the OS container, with open and unsaved files in the application using the power button. This does not suspend the Container OS, and when you start the container again, that data will be lost.

Note: The power button shutdown applications and the Container OS.

The Edit options allow you to view/change the applications configuration parameters, and these amount to simple variables such as name, .exe path, and description. Currently, there isn’t a browse option to locate the .exe, you have to type the path manually. Incidentally, this sort of browse functionally looks easier on paper than it is to implement in practice especially if you want to make sure the Container remains a secure environment.

You can upload an icon to act as friendly logo, this currently means browsing for .png, .jpeg, and .jpg files. This browsing is from within the Host OS, not the Container OS. So, I took a screen grab of the TextEdit application from the Apple Mac. I think in future Droplet Computing will inspect the .EXE and present icons from with it.

What can I say I like pretty icons!

Adding a New Application

The Droplet Computing Container is password protected, and adding a new application requires the administrator password. I’m not sure quite where this is set or stored. I’m assuming that when the container is first created a password is set, I assume the password is passthrough some sort of salting process to make impossible to decrypt – I assume it is stored somewhere within the .droplet image file. Droplet Computing set a default password for both access to the Container, and it’s also the same password that is passed through to the Container OS environment for administrator access. I understand that future versions of Droplet Computing will have the capacity to change this password.

Remember, Droplet Computing passed recent PEN Testing with flying colours, and so I don’t imagine this is an issue.

Once validated the container unlocks the options to add more applications for the user, revealing a + application tile from where you can add the parameters.

Note: My sample .droplet image was a bare-bones install of Windows XP, that didn’t even include MSPaint.exe! A situation that might bring a tear to the eye of old-timers out there who are fans of pixelated artwork. This configuration of the tiles view is user specific and is not saved to the .droplet file. It means the .droplet file can be replaced with a new image/build without upsetting the users configuration.
Note: First time I tried this it didn’t work because I’d missed the r in Program! There is no clipboard buffer in the container so you cannot copy and paste from the device to these fields or copy them within the application. I assume the lack of a clipboard is a security decision. Copy and Paste is allowed between applications within the same container.

There’s currently no “browse” option here to navigate into the container, nor does Droplet Computing validate these paths to make sure they are correct. I knew that a legacy version of Microsoft Office 2010 had been pre-installed to the Container OS, so the way I validated the path was by doing the following:

I asked Droplet Computing to “Show Container”

Which reveals the administrator-only “spanner” icon, that allowed me to run Windows Explorer to check the path to winword.exe

Once I’d found the install directory, I was able to make a note of the path (without speech marks incidentally) and the .exe.

As you can see in the screengrab above, this administrator mode exposes aspects of the Container OS shell in the form of the Control Panel, Explorer, Task Manager, Command Prompt, PowerShell (if installed) and sending the Ctrl-Alt-Del keystroke to the Container OS.

When my work was done, I could see both Notepad and Microsoft Word.

There’s currently no method of copying a tile, to be able setup a new application by quickly modifying the path to the .EXE and the icon file. That said, this is a one-off operation that doesn’t take that long to configure. I notice there’s no way to drag tiles around, and they are sorted by application “name” field. So used a naming convention of Microsoft Word 2010, Microsoft Excel 2010 and so on to make sure they were grouped together.

Once multiple applications are available to the user they can switch back to the list of tiles, using the “Show Apps” option. This appears once the 1st application is loaded in my case, Microsoft Excel 2010

They can then load another application such as Microsoft Word 2010. The task bar shows the applications that currently open like so:

Installing new software to the Container OS

Adding new software to the Container OS involves a couple of steps:

  1. From host locate the source software
  2. Place on shared location in such as NAS Server
  3. Download and Run installer within the Container OS

As example of doing this for Windows XP I used PuTTY. By far the easiest thing to do is to put the .exe or .MSI on a NAS server, and then map a network drive from the Container OS to the NAS Device. I did this by entering the administrative mode, and then running a Command Prompt

From there I was able to carry out a net view on the IP address of NAS server to see the shares on it:

And then a net use command to map a network drive:

From there I could use the copy command to copy the PuTTY.exe file to C:\Program Files. Once that was done, I was able to add PuTTY as tile to main view.

This work does beg the question on how networking is arranged inside the Container OS. In my case the Windows XP instance has a DHCP address from an internally supported IP range. So, it did not get an IP address from my home router. DNS and Routing queries get sent to an internal service which then piggy backs off the host networking. This allows for outbound access to my network, and the internet – but with no corresponding inbound access. This was just-enough networking to get me to my NAS server. As an aside, I notice Internet Explorer was not installed in my Windows XP image.

Conclusions:

From what I can see Droplet Computing has put together a robust release 1.0 product with PLENTY of scope for future features and functionality. They have developed their own in-house approach that solves the issue in a unique way. Personally, I think that’s no small achievement. It’s perhaps worth restating what those issue entail. As with server virtualization there’s always been that challenge of extending the lifetime of a legacy application beyond the life of the hardware and operating system for which it was first designed. Other attempts have been made using server-based computing (Citrix/MSFT-TS) and virtual desktop infrastructure (Horizon View and others). But these are have been datacenter focused solutions. I’ve championed both of these approaches in the past, and continued to do so – with the caveat that they place user-workloads in the most expensive computing space known to the Enterprise. So whilst VDI and SBS remain useful tools in a companies armoury, we have to acknowledge that much vaunted “death of the PC” and “Year of VDI” hasn’t happened. The PC remains the resilient and cost effective method of delivering a compute experience that hasn’t been eclipsed by the tablet or the dumb-terminal (I prefer to call them smart terminals, personally)

The bonding of hardware, operating system and an application has been ‘loosened’ in the last couple of decades. But they are still close coupled together. It’s only really containers on the server-side with technologies like Docker and Kubernetes that has really been a significant challenge and change in the way applications are developed. I think the time is right for that “container” approach to applied to desktops as well. Creating a mirror image of what’s happening in the space of server-side application or new paradigm for how companies might deliver applications in the future. The issue of legacy application support isn’t going away, because it has gone away for the last two decades (and a bit more) that I’ve been in the industry. So as companies see operating systems like WindowXP and Windows7 fall off the support cliff, I suspect that the same situation will be faced with Windows8/10. And there’s more. If I thought technologies like Droplet Computing were just about legacy applications, I’d be less excited by this space. The fact is I think many companies once they harness the power of container technology for legacy applications, will be thinking about using at as method of deploying new applications.

Droplet Computing: Drops Some NewsLets

Disclaimer: I’m not paid or engaged by Droplet Computing. And I wasn’t offered any trinkets or inducements for writing this series of posts. I’m just interested in what they are doing. The CTO is a former colleague of mine from VMware, and admire anyone’s hutzpah to walk away from the corporate shekel to do their own thing.

 

This is going to be series of blogposts about Droplet Computing. I’m trying to eschew my usual TL:DR approach to blogging in favour of an approach that more reflects the gold-fish style attention spans that scrolling news has engendered in the population at large.

In case you don’t know, Droplet Computing does “Containers for desktops”. This is the kind of typical “company-as-sound-bite” that is used as shortcut to describe what a company does. If you want to some more technical detail check out the blogpost that will join this series.

The simple idea is delivering end-user applications for Windows, Mac and Linux in a container. This is NOT your 2006 desktop virtualization (so not “Year of VDI” narrative that vendors have being flogging like a horse deader than Mrs May’s Brexit Deal), and nor is it the application virtualization that involves “capturing” and “sequencing” applications into a special runtime (aka AppV, ThinApp and dozen other wannabees).

With Droplet Computing, applications are installed natively to an OS library held within the container, in such a way that anyone who knows how to click “Next” could build the environment.

So, the newslets are this.

A Special Person joins Droplet Computing

No, not me. I’m not that special.

That very special person has joined Droplet Computing as non-executive director.

Who?

Adam Denning.

Who’s he?

None other than Bill Gate’s former technical advisor. That’s who.

This is “big” for a number of reasons. It’s a vote of confidence in Droplet Computing. It’s big because Droplet Computing is tiny (I think there’s less than 15 people currently engaged – I could be wrong about this figure) So the arrival of such an industry heavy weight is relatively and cosmic significant. Adam’s the kind of figure that would convince folks being paid hefty sums working at some oil tanker corporate to do something infinitely more interesting – and riskier… But there’s something more as well. It’s about sending a message that Droplet Computing is in it for the long game. I mean who knows what the future brings, but when heavy weights like Adam join there’s something take note of…

This is what Adam has to say about himself on Linkedin…

“Technical strategist and architect with proven software delivery skills. Over 25 years’ experience with Microsoft in varied technical roles, the last 22 in its corporate headquarters in Redmond, USA, and including a 3-year stint as assistant technical advisor to Bill Gates. Led teams of over 100 people with multi-million-dollar budgets and delivered products used by 100s of millions of people around the world. Deep technical knowledge, thorough strategic thinking capabilities and extremely quick learning. Significant customer-facing work, oriented around developer strategy, working to ensure customer success and gathering feedback to improve Microsoft’s products. Presented and communicated at CxO-level, at 5 to 5000+ attendee conferences, and published books, magazines and blogs. Recently led the evolution of Microsoft’s platform strategy around Windows and its derivatives.”

This is a chap who hasn’t just management stuff. See I told you it was vote of confidence. That’s about as much as I could glean from Google aside from….

The other thing that’s nice about Adam is his natty selection of bowties. Bowties are super cool. And have been ever since Dr Who announced this that it is a truth universally acknowledged, that a man in possession of a good fortune, must be in want of a bowtie.

Droplet Computing Security Testing

The 1,000 foot of this NewsLet is that they passed with flying colours. Okay, case closed… Well, not quite. The whole point of this sort of testing is to shout it out from the roof tops so folks are convinced your product is safe to use. This is especially true of Droplet Computing since their first use case is about allowing legacy applications associated with legacy operating systems to continue to run on OS’s that are still current and patched.

A couple of years ago the UK was hit by WannaCry, by a wave of WindowsXP instances that could not be protected (because Microsoft saw fit to keep the patch to themselves). Our beloved National Health Service was perhaps the most impacted, as they have a LOT of applications still in use that are too expensive to refactor and rebuild for a new OS. Sadly, the whole thing got politicised by the media and others, and the narrative became dominated by wider concerns around underfunding our NHS. The situation is somewhat more nuanced. Even if the government’s cup of money was overflowing, it would probably still be decided that to maintain the older system was the best use of resource.

Incidentally, some might say this use case is dangerous because it means Droplet Computing is chasing a diminishing market of legacy applications that will one day be so redundant they will be switched off. I think this thinking is a bit woolly. Firstly, what is current today will be legacy in 5 years’ time, and IT history has a habit of repeating itself – the first time as tragedy, the second time as farce. But secondly, I could easily see customers loving Droplet Computing so much they choose to make it their de facto method for deploying new and current applications. Okay, so I know that’s a grand claim. And it remains to be seen. We will have to see if customers bite the Droplet Computing cherry.

Anyway, Droplet Computing engaged the services of NCC group to do the tests. The assessment was conducted from February 14 to February 18, 2019 on a Windows 10 laptop with two Droplet Computing containers, one containing Windows XP, with a variety of outdated software, including Office 2010, and the other with Kali Linux containing a large number of malicious tools useful for breaking out of the container. The main outcome of the report was that the container service was not accessible remotely, a huge advantage for organisations in securing enterprise applications. Here’s what NCC Group reported…

“The system being assessed allowed organizations to run existing applications within a secure containerized environment within a browser. The portability of running in a browser would allow these organizations to decommission unsupported and vulnerable operating systems in place of fully updated and supported versions, while still being able to use production software.”

Stop! Read that quote back again. Now read the bit in bold and italics again. Interesting, huh?

Droplet Computing is now using these results and working with NCC and Public Sector clients to achieve Cyber Essentials PLUS accreditation. Cyber Essentials is a UK Government-backed, industry-supported scheme to help organisations protect themselves against common online threats. The idea is make the UK the safest cyber location on the planet. Assuming some civil servant doesn’t download everyone social security details to a USB stick and leave on a commuter train to Northholt.

http://news.bbc.co.uk/1/hi/uk/7449927.stm

Admittedly, a lot of these cases are more than a decade old now. Things have moved on, except for government ministers who persist in carrying important documents of state in full view of the media.

Summary

So, a senior Microsoft guy onboard, and PEN Testing complete. Pretty handy dandy. I think Droplet Computing is finally positioning it to release their first 1.0 product, less than a year after showcasing “minimal viable product” or proof-of-concept at last year’s TechField Day when they came out of “stealth”. The PEN Testing is interesting. I figure it will be constant balancing act between providing the features customers desire, against maintain the security credentials. However, as VMware demonstrated with ESX. It helps if you can set a good baseline of security from the get-go, rather than retro-fitting it once the horse and your credit card details have bolted.

Next up, and practical and technical hands on walk thru of the product today

Cloud Field Day: Droplet Computing – Any App, Any Where, Any Device

Yes, we have heard that message before from many, many companies in the past – but how many companies have REALLY delivered on that promise. And I mean REALLY delivered on that promise…

The trouble has been that in order to achieve the laudable goal in the past you have needed a truckload of infrastructure to deploy either a server-based or virtual-desktop-based environment – and run those Apps from an expensive data center location usually in the context of a Windows Operating System. Once I said at a user group in the US that putting desktops in the data center (the most expensive computing environment known to human or beast) is unlikely to result in massive cost savings. As I recall, one person stood up and clapped me for my honesty. It doesn’t matter how many TCO calculators you throw at the approach, the data center business is an expensive one. And one that according to our public cloud vendors, is one business customers can’t wait to get out of.

The Technology – Droplet Computing

At the Cloud Field Day in Silicon Valley back in April – Droplet Computing came out “stealth” to reveal they have developed a client side container technology, that will allow practically any application to run in the context of web-browser. Here’s a quick overview of that container technology:

So, there’s a couple of components going on here. But in simple terms, the container sits inside a web-browser which essentially offers the runtime environment, surrounded by a series of supporting “libraries”. Possibly the most significant is the use of WebAssembly which handles the job of intercepting the machine code generated by the app sitting in the container. A clunky analogy would have the web-browser like the virtualisation layer, and the container is like a VM, with the user app sitting inside the VM. All this is done however, without the bloatware of either a server-side hypervisor or client-side virtualisation and an “operating system” sitting inside that VM. That was tried in the past with technologies such as VM Player, ACE, Workstation or Fusion – or worse still downloading an entire VM from the corporate data center – just to run a measly little Windows App. Now I’m not saying that VMware Horizon or Citrix XenApp are “wrong”, it’s just for many they were sledgehammer technologies trying to crack a nut. Of course there the physical system that end-user sits on needs operating system – but that could be almost anything you care to think of.

So, this is ultra-compatible. How compatible? You could easily “natively” run a Windows based App inside a Droplet Container under an Intel-based Apple Mac. All without installing Windows or having to power-up or resume a Windows VM. In fact, the processor wouldn’t even have to be Intel-based, it could be an ARM based processor if necessary. This opens the door to being able to those Windows Apps running on chipsets for which they were never designed.

That lack of Windows requirement stems from the use of “wine” from the world of Linux. Wine has had a sketchy history in the world of Linux as a way of natively running Windows Apps under a Linux context – but it has moved on and improved over the years.

In terms of the underlying physical system – all that’s really needed is a relatively modern web-browser  with WebAssembley enabled – which is sufficient to support the Droplet Container. Currently that’s Chrome v6.0, Firefox 5.2, Safari v11, and Internet Explorer v16. Mobile device such as Android-based phones/tablets (Android v6.2) and Apple iPhone/iPAD (iOS v11.1).

So, in a nutshell. Droplet Computing does for desktops what container technology has done for server-side code development and code distribution. Adding a layer without the overhead of a virtualization layer+operating system and other dependencies.

The Use Cases

ANY, ANY, ANY means MANY, MANY MANY.

But let’s start from scratch. The end-user computing world is a very different one from the narrow world of Windows PCs, and the old days of “Virtual Desktop Initiatives”. Whilst it would be foolish to discount server-based computing and VDI, neither succeeded in going mainstream – or become the de-facto way that users got their apps. They remained corralled into a particular niche for Dilbert-style users who sat in their cube all day. That way of working is on the decline with many of us being more mobile or working-from-home (WFM or should that be WTF?) – plus we all now have at least three devices (if not more) in the shape of laptop, tablet, and smartphone.

Whilst attempts have made to duplicate apps across those device types – this has resulted in compromises either in the “app” driven world of the iPAD or in the web-driven world of Office365. It’s always meant some uneasy compromise of the experience – which support folks have to excuse or explain away. So, this new way of working has spawned attempts to bring everything under one house via things like VMware’s WorkspaceONE – a portal to a plethora of different ways off delivering apps (SaaS, Virtual Desktops, Application Packaging – like ThinApp, AppVolumes, Microsoft App-V and so on, and on and on…). For me the difference with Droplet Computing is they are offering a net-new method of delivering the App – in a container, executing on a device of the end-users choosing with their preferred web-browser. Incidentally, I still think these one-stop-shop “App Stores” will still be needed for ID management, entitlement and security reasons – but I can see Droplet Computing being the Apps that are advertised there – to be downloaded and run on the end-users’ device. And of course, if you must have centralised VDI they are possible target too…

Clearly, legacy apps will be an important market – but I personally believe that this approach will pay dividends for new applications as well as older ones. Although to be fair it’s those older applications that often prove to the bane of everyone’s life. Often they’ve been developed in an OS with lower security requirements – and that often means ‘breaking’ the rules and regulations about OS hardening – just to make them work. The older they become the more they are likely to break as their dependencies themselves become incompatible or discontinued. This then has a knock-on effect to other important requirements such as meeting compliance during an external audit, or merely ensuring the apps are as quick and reliable as they once were. The dizzying releases of Windows and their associated Apps means it’s really impossible for an enterprise to freeze its world based on a particular approved “build” and blend of OS/Apps. This just doesn’t sit well in a BOYD era where CorpIT has no clue or control over the end-point the user chooses – never mind that that they may be using a form-factor such as tablet. So, Droplet Computing’s container vision and technology offers a tantalising promise of escaping these limitations and restrictions.

There are some interesting parallels between the early days of virtualisation and what Droplet Computing is doing.

Firstly, there’s a low-hanging fruit market of legacy apps that are still used by business but won’t be supported or won’t work on new operating systems. That includes App’s developed by ISVs who may not actually be trading anymore. The cost of rewriting those legacy apps far outweighs the usefulness to the business, so away of extending their life time beyond meaningful usage is appealing.

Secondly, Although the software running in the container is unmodified and runs natively – customers should be aware that Droplet Computing is not responsible for the licensing policy or support agreement of the ISV. Of course, if they have ceased to operate there’s a great deal of leeway there, but if the ISV is current – they might decide (as they did with 1st Gen virtualisation) simply not to support it or licensing it in a such away as to reduce its competitive value. For instance, a Droplet Computing user license allows the end-user to run 3 copies of the Droplet Computing software – enough to cover the 3 most popular devices a user might use (laptop, smartphone, and tablet).

However, the ISV might choose to charge the business 3 times for an application that has been “installed” on three different devices. Remember many of these legacy applications that represent the low-hanging fruit have quite antiquated licensing policies that are often the bane of many Citrix XenApp or Horizon View admin. That said, the potential cost savings from not having to run the older infrastructure – and having that app execute on expensive compute (the data center) but on cheap compute (the laptop) – could outweigh that restriction. Put simply it might be cheaper to suck up the additional license costs, to save money elsewhere. Personally, my hope (the same hope I had with Gen1 Virtualisation) is that ISVs review their licensing policies with a view that anything that drives consumption also preserves market share – and that it’s not in their interests to corral their horses and carriages in cycle in order to “protect their revenue stream”.

Looking back on this paragraph, I’m perhaps over-egging the impact of these licensing considerations. Perhaps ISVs have woken up the multi-device world we now reside in, and these antiquity licensing policies are a thing of the past?

Early Days…

So, its early days for Droplet Computing. They have secured their first round of VC funding and come out of stealth – and they are on the cusp of releasing their first release candidate 1.0 GA. I hope to get some stick time with the technology, as I believe getting one’s hands dirty is the first step to learning the advantages, disadvantages and limits of technology. I’ve waited a while for a truly new and innovating technology to grab my eye. And not just a rehash of existing bits and bytes. I think what Droplet Computing is doing is very, very interesting – and they are certainly a company to keep on your radar.

California here I Come – Cloud Field Day

Very soon I will be heading of San Jose, CA for the start of the Cloud Field Day. Time has certainly flown not least with my sabbatical from the industry – together with a stint in VendorLand with VMware – precluded my attendance on this frankly rather wonderful event. The Field Day’s are organised by the Industry Legend in his Lunchtime, Stephen Foskett with the unstinting hardwork of a retinue of support staff. As delegate I can tell you they certainly dot the i and cross the t’s. I even have a letter of invite from TechField Day for US Immigration in case just case they get gnarly. Although I must admit my first trip to the US in two years was peachy smooth when I was there for the Ravello Bloggers Day.
