Not a particularly challenging book on this subject. It starts with the basics and never really gets to the guts of developing SOA applications. However it does a good job of explaining the basics of the standards and key concepts, although it does over use very simple diagrams. I know a picture tells a thousand words, but in this case some of the pictures could be explained in 10 words without too much difficulty.
That said I found it very useful and particularly liked the concept maps, that showed how all of the various standards/services related to each other.
If you want a more ambitious book then Enterprise Service Bus by David Chappel, looks promising:

Jon shows off the amazing possibilities enabled by google maps, combined with GPS and provides a great example of multi-format screencasting as well. Screencasting is going to be big news! This link shows how he made it work.

Tarantella has always lagged behind Citrix, but with the advent of “Secure Global Desktop”, reviewed here, and at $60/concurrent user it offers incredible value for money and near key feature parity, especially for enterprises with a very low concurrent to potential user ratio.

I have mentioned before how much I like VMWare and how I have been using it not only to support my Labs requirements for years, but also as a secure client to my company network, ala VMWare ACE. I have also been looking at other application Virtualiszation technologies and Server Based Computing approaches, so it was nice to see a couple of the ideas nicely presented in this article on using VMware ACE combinted with SoftGrid, here is an extract:
What is perhaps less well known is that VMware can also provide an important service for desktop hardware. This is partly because its desktop capability is still evolving. The VMware desktop capability, VMware ACE, is currently in beta release. It provides a standard virtual hardware configuration for the desktop, including the OS, web browser and all the applications – all of which are distributed from a central point. VMware ACE solves a major desktop support problem by enforcing standardization and thus making local software installation of any kind unnecessary. It is not the resource utilization that is the issue here, but manageability.
However, on its own VMware ACE does not solve all the support issues. This is where Softricity’s SoftGrid …

Yet again Jonathan Scwartz continues his policy of openly and very clearly describing Sun’s strategy for all to see. I have never seen the like of it before, although I can only commend him for it. As always I strongly recommend that you read his blog regularly, but here are a few snipits from his latest post which I liked:
On his positioning of the role of Linux today:
But let’s be clear. Do I expect an investment banker at Goldman, Sachs to pick up the Java Desktop System? No. No way. He’s not our target demographic, not a route to make 120 million into 1.2 billion. A call center in Bangalore, a factory in Tennessee, a generation of kids that care more about ringtones than Win32 legacy? Dedicated internet terminals in shopping malls, touch screens in phone booths, the world’s academic environments? There’s a market calling.
Which I found interesting because many of these applications are best served by embedded or thin client approaches rather than a full Linux distro.
Why is music download on phones measured in the billions of dollars (vs. the paltry music download business on PCs, even with iTunes)? Because phones are authenticated (with a …
Microsoft watch reported today that Microsoft are dropping the “anywhere access” functionality scheduled to ship in Windows 2003 Server R2. Which is a real disappointment, tempered slightly by the fact that Citrix continue to innovate around their platform.
In May, Microsoft officials said to expect R2 to include bug fixes for Windows Server 2003, as well as some of the 12 to 15 Windows Server “feature packs” that the company has rolled out since Windows Server 2003 shipped in April 2003. These feature packs include Active Directory Application Mode, SharePoint Services, Windows Update Services. Officials also said at that time that R2 would include full Network Access Protection and “Anywhere Access” capabilities, the latter of which was expected to draw on Microsoft’s next-generation Terminal Server features.
But now Microsoft has decided to push the Network Access Protection security capabilities it into Windows Server “Longhorn,” the Windows Server release due in 2007.
“Delivering Network Access Protection in R2 would have forced too many changes at a low level,” said Samm DiStasio, a group product manager with Microsoft’s Windows Server division, in explaining the company’s decision to postpone the feature until Longhorn Server.
At the same time, the Redmond software vendor has …

VMware have just announced ACE, this is how they describe it:
VMware ACE is an enterprise solution for IT desktop managers who want to rapidly provision standardized and secure PC environments throughout the extended enterprise. VMware ACE installs easily, improving the manageability, security and cost-effectiveness of any industry standard PC. VMware ACE enables IT desktop managers to apply enterprise IT policies to a virtual machine containing an operating system, enterprise applications, and data to create an isolated PC environment known as an “assured computing environment”. VMware assured computing environments are self-policing, protect enterprise data, and enable safe access to enterprise resources.
I like the idea, I have been using VMWare myself for exactly this requirement. On one of my home servers that sits on my home network I have a Windows XP VM, configured with corporate firewall, AV products, locked down configuration and VPN client. I use this VM to connect to the company network.
This has two advantages, The company network is pretty well isolated from my home network and I am well isolated from it, (since its pretty big and represents a fairly large threat). I would prefer to be able to just fire up a Windows Terminal …

For years, Citrix has been the only choice for software to power server-based computing environments. Sure, Microsoft’s Terminal Server products were out there, but their features paled in comparison to those of Citrix MetaFrame Presentation Server. However, as Terminal Server continues to gain ground as a standalone solution, many people wonder whether they need to […]
