There are essentially three ways I found that differ vastly from on another.
- Jailbreak, then “un-jailbreak” once you install flash (I am not going to go into all of that)
- Provide a browser through a “VM”. That is host an app through some software server in the cloud.
Jailbreaking is out. We are not about to go to war with apple (although someone should). Smokescreen won’t really work out, plus it is not very “corporate ready,” which leaves us with the VM/cloud/SaaS solution. So via iPhone/iTouch I found an app called Cloud Browse. This is pretty nifty it is essentially Firefox hosted up in the cloud. It works, but there are some pitfalls. First of all, its unsupportable. If one of our clients says “ITS NOT WORKING” angrily all we can say is try again later? Also, it could potentially cost a ton, and its not a fixed cost. That is we need to buy subscriptions for each person who wants to use the app so they don’t end up on the generic/anonymous connection pool that may or may not get a connection depending on popularity at that moment in time. Do I need to mention that if you are going through some VPN service you are essentially exposing all your delicious corporate secrets? Lastly, it looks like crap on the iPad.
I mentioned the VM solution to my manager, and he said “OH, that kinda sounds like something Citrix probably does.” I did some research and found 2 must have apps and a pretty rockin video that explains a few things.
Step One (setup a server that doesn’t quite work yet for practice and experimentation):
First thing you should do is follow the steps in the video below to get your Amazon cloud account all setup with XenApp 5.0. The AMI mentioned in the video doesn’t work with the iP[hone|ad]. I believe the AMI mentioned in the last link will work out though.
- http://community.citrix.com/display/xa/Amazon+Web+Services (for a decent guide for how to set things up)
- http://community.citrix.com/display/cdn/Windows+Apps+as+a+Service (for most up to date credentials and AMI for the video, right now ami-71749f18 is what you need)
- http://community.citrix.com/display/cdn/Delivering+Windows+Apps+to+an+iPhone (the port for AWS S3 is currently behind a firewall, and it is needed to setup the AMI, this should apparently work. I would recommend this AMI if it works!)
Next, log in and open up your “desktop” app, which may take up to 10 minutes even if it says “running” in amazon, server error means its still starting up. You will see all sorts of warnings about XenApp not having licenses, logins failing, terminal services needing licenses, but this is all normal and if you can open internet explorer you are doing just fine. At this point you may want to try adding apps into Citrix Access Manager, which is extremely easy (if you have a question about it feel free to ask in the comment section). I installed Firefox, Adobe Reader, Flash and AIR. I then installed an AIR application and was able to create apps in the manager tool. I used Firefox, the air application, and adobe reader.
Step Two (configure apps and reconfigure iP[ad|hone] and try it out):
You may want to add a new user. We will use this user to connect to the server via the iPad. The cool thing about having individual accounts is the same as doing so on a normal machine. Users can save their own settings and preferences. The same is applicable here.
Now go through App Store on the iPad. You can just download the Citrix Receiver for free. Go ahead and use your IP address as both the address and domain. You need have your username in the format: ComputerName\Username. If you are now able to open your web browser and launch it. Everything is working fine. Go to youtube.com and open up a video. There should be some choppiness as is expected, but hell it works. It may not be 24->30fps, but it gets the job done, and its supportable/secure.
At an enterprise level. This is extremely affordable. You only pay for XenApp once. The receiver is free. You may need to purchase Windows Server 2008 if you are doing this internally. Then for about 60 concurrent users we are looking at around 5 grand total. This is much more affordable than redeveloping a ton of software. One thing to note though. You should assess how much interest there actually is around all of this. The last thing you want to do is have a person dedicate about a week of their time trying to set this thing up and have no one ever use it.
Finally, let me put up a little disclaimer. I know nothing of these sorts of things. I just had a business need and tried my best to figure out how to get this to work. Questions shouldn’t necessarily be directed at me. Honestly I am not a subject matter expert for XenApp, Citrix, Windows Servers or iP[ad|hone]. Most of this stuff was pulled from best guesses and gleaned information. I will do my best to answer questions if I do receive them. In any case, I hope this was helpful to someone :)! Now I open the forum… Any other ideas?
