In the run-up to the next Cloud Expo, 7th Cloud Expo (November 1–4, 2010) being held at the Santa Clara Convention Center in Silicon Valley, it's time to give my earlier list a complete overhaul. Here, accordingly, is an expanded list of the most active players in the Cloud Ecosystem. I have increased it from the 'mere' 150 I identified back in January of this year, to 250, testimony – as if any were needed! – to the fierce and continuing growth of the "Elastic IT" paradigm throughout the world of enterprise computing. Editorial note: The words in quotation marks used to describe the various services and solutions in this round-up are in every case taken from the Web sites of the companies themselves. Omissions to this Top 250 list should be sent to me via Twitter (twitter.com/jg21) and I will endeavor to include them in any future revision of this newly expanded rou... (more)

Creation and Consumption of Web Services with PowerBuilder

PowerBuilder 12.5 introduced a number of significant enhancements to web services support, both for creation and consumption. In particular, the following were introduced as new features in PowerBuilder.NET: WCF client proxy WCF service target REST client proxy We're going to look at what those new features provide and how to use them. We're also going to look at how we can package some of that functionality so that it can be used from PowerBuilder Classic applications as well. Windows Communication Foundation (WCF) First though, some background. When support for a web service client was first introduced in PowerBuilder 9, it was done based on an open source library called EasySOAP. There were some limitations with that implementation, primarily because the EasySOAP library only supported SOAP 1.1, was limited to XML over HTTP transport, and provided no support for an... (more)

What is Enterprise Cloud Computing?

Jill Tummler Singer on Ulitzer What is enterprise cloud computing? Simply stated, it’s a behind-the-firewalls use of commercial, Internet-based cloud technologies specifically focused on one company’s or one business environment’s computing needs. Enterprise cloud computing is a controlled, internal place that offers the rapid and flexible provisioning of compute power, storage, software, and security services to meet your mission’s demands. It combines the processes of a best in class ITIL organization with the agility of managed, global infrastructure to make your IT faster, better, cheaper, and safer. Enterprise cloud computing gives your business agility, survivability, sustainability, and security. I believe commercial solutions-whether its Google's cloud or Amazon's web services-may be perfect for many companies. But, some corporations and government agencies... (more)

Perhaps I Haven’t Made Myself Clear...

I've been discussing HTML5 for some time now. In July of 2010, I mentioned that I wasn't particularly concerned about PowerBuilder supporting HTML5 in the initial PowerBuilder.NET release (12.5) because: "HTML5 is largely still in its infancy, and there appears to be too much opportunity for it to fragment as previous HTML standards have done." [1] In December of 2010 I devoted an entire editorial to HTML5 [2], noting that: "I have some basic concerns that make me reluctant to recommend using HTML5 as the basis for any line of business application development in the near future." But also recommending that as far as a future version of PowerBuilder, Sybase should: "Still focus on Silverlight, still work on HTML5 as well, and give us the capability of generating applications that implement both. If the Silverlight player is available, use that, and if not then downgrad... (more)

Hurdles To Cloud Adoption Swirl Around Governance

Welcome to the latest BriefingsDirect Analyst Insights Edition, Vol. 42. Our latest topic centers on governance as a requirement and an enabler for cloud computing. Our panel of IT analysts discusses the emerging requirements for a new and larger definition of governance. It's more than IT governance, or service-oriented architecture (SOA) governance. The goal is really more about extended enterprise processes, resource consumption, and resource-allocation governance. In other words, "total services governance." Any meaningful move to cloud-computing adoption, certainly that which aligns and coexists with existing enterprise IT, will need to have such total governance in place. Already, we see a lot of evidence that the IT vendor community and the cloud providers themselves recognize the need for this pending market need and requirement for additional governance. So...

The PostOpen Event – Why It Is So Important

Normally I try to write applications on the DataWindow or Appeon but every now and then I get a question that makes me sit back and say, "Huh?" In this case the question concerns the PostOpen event. I've seen that event named different things: ue_post_open, postOpen, post_open, ue_postOpen, etc. It has, as far as I can see, always had post and open in the name of the event. Further, just about every framework that I've ever seen has had that event in the base window. The question that I was asked was, "Why is that event there?" The programmer wanted to know why there was code in the post open and why was it not just put at the end of the open event? At first I was really confused by the question. It was like he was asking me why do we have arrays? I just couldn't imagine not knowing the answer. Then it occurred to me that I learned the answer to that question from a ... (more)

Gradients, Not Glitz: Methods to Modernize PowerBuilder User Experiences

Surprisingly few applications have used DataWindow gradients since they were introduced in PowerBuilder 10.5. Modern applications frequently have controls with gradients. They can give a fresh look to an old application. Where developers used solid colors to highlight columns, gradients add nuance, flair and more. This article will show practical methods and guidelines for applying gradients to convey meaning, grouping, and give visual focus. It begins by introducing the basics of gradient properties. The discussion advances to many types of subtle effects for general visual interest. Examples are "soft spots" or "title bar shades," or focus indicators for rows and columns. Gradients can be used in detail and group bands and framing free form objects inside - or instead of - group boxes. Readers will see distinctive DataWindow controls like edits, checkboxes and ra...

Silverlight Is Dead, Long Live Silverlight

There's been a lot of discussion since Microsoft's BUILD conference on the fate of Silverlight. (Something that is an issue for us because Sybase was originally looking at supporting it for web app development in PowerBuilder 15.) Contrary to what a number of the pundits and would-be pundits have said, I don't think it's quite accurate to say that Silverlight is dead in Windows 8. I think it's more accurate to say it's evolved. As background for those who haven't been following this closely, Microsoft announced that the Windows 8 operating system would support two kinds of applications: traditional "desktop apps" and the newer "metro style apps." What would not be available in the Internet Explorer provided with Windows 8 would be support for any plugins, either Silverlight or Flash (see Figure 1). It's that last part (no plugins) that have raised the concern about t... (more)
