How Does It Work?
I was just putting together some information and slides for a presentation to my fellow coworkers on the high-level technical architecture that Appeon Web uses to webify any PowerBuilder Classic based application including ones built using the PowerBuilder Foundation Classes (PFC)!
The main interesting aspects that I am always amazed at with the Appeon Web product are things like: removes the PBVM dependency, builds re-entrant & multi-threaded code, converts your 2 tier application into a 4-tier model, builds full 32 or 64 bit compliant code, includes its own Data Access Layer (DAL), supports all the popular DBMS systems (now including mySQL & HANNA), supports all the popular application servers, can deploy your PB application using either a J2EE or .Net architecture, provides its own security mechanism or allows you to integrate with LDAP, incorporates system monitoring, supports fail-over & load balancing, etc. To me .. that's a "whole lot of bang for the buck" when it comes down to adding up all the features you get right out-of-the-box!

Appeon Web automatically converts your PowerScript code and objects into C# / Java, jScript, XML and HTML. It needs to do this in order to support the web paradigm, as follows:
- Web Browser: The Web browser delivers and runs the presentation layer of the Web application.
- Firewall: Port 80 is supported to comply with corporate security requirements.
- Web Server: The Web server hosts the presentation layer components for the Web application. The presentation layer is comprised of a set of HTML, XML, java script files and an ActiveX run-time library. The Browser and Web Server exchange information using standard web protocols.
- Application Server (Java or .NET): hosts the business and data access logic for the Web application.
- Database: Existing DBMS & application databases used by the Web application.
Appeon DeveloperThe Appeon Web product is actually delivered and utilized in various components. The first key component is the "developer plug-in" which integrates seamlessly into the PowerBuilder Classic integrated development environment.

Appeon ServerAppeon Server provides key services that make the web applications come to life and extend their high performance nature, as follows:
- Database Connectivity
- Data Access Management
- Transaction Management
- Session Management
- Web Applications Management
- Server-side Integration like calling Web Services, .NET components, Java components, etc.
- Security Management
- Load Balancing
The Appeon Web product allows the PowerBuilder developer to continue to use the IDE that they are most productive in and extend that into the web world by incrementally generating the web components that are needed and deploying these seemlessly as the programmer codes and saves their PB objects! Once the application is ready to test in the IDE, Appeon is also ready to test the web version ofr that application using the n-tier architecture of the web.

As you can see in the above diagram, as the PB developer saves objects into any of their PB Libraries - Appeon Web translates that work into the language of the web and deploys the related components to their respective server(s).
You can give the Appeon Web system a try by downloading the trial version from Appeon. For those of you who are ISUG-TECH members at the Core (previously called "green") or Gold level, you can get the Appeon Web "developer" version for free as part of your membership.
Give Appeon Web a try .. you will be amazed at what it can do and why you did not try it sooner - Chris!

The Internet of Things (IoT) is rapidly in the process of breaking from its heretofore relatively obscure enterprise applications (such as plant floor control and supply chain management) and going mainstream into the consumer space. More and more creative folks are interconnecting everyday products such as household items, mobile devices, appliances and cars, and unleashing new and imaginative scenarios. We are seeing a lot of excitement around applications in home automation, personal fitness, and in-car entertainment and this excitement will bleed into other areas. On the commercial side, m...

In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (IIoT) applications and principles. But adding sensors and wireless connectivity won’t work in environments that demand unwavering reliability and performance. In his session at @ThingsExpo, Ron Sege, CEO of Echelon, will discuss how as enterprise IT embraces other IoT-related technology trends, enterprises with i...

The Internet of Things (IoT) is causing data centers to become radically decentralized and atomized within a new paradigm known as “fog computing.” To support IoT applications, such as connected cars and smart grids, data centers' core functions will be decentralized out to the network's edges and endpoints (aka “fogs”). As this trend takes hold, Big Data analytics platforms will focus on high-volume log analysis (aka “logs”) and rely heavily on cognitive-computing algorithms (aka “cogs”) to make sense of it all.

Advanced Persistent Threats (APTs) are increasing at an unprecedented rate. The threat landscape of today is drastically different than just a few years ago. Attacks are much more organized and sophisticated. They are harder to detect and even harder to anticipate. In the foreseeable future it's going to get a whole lot harder. Everything you know today will change. Keeping up with this changing landscape is already a daunting task. Your organization needs to use the latest tools, methods and expertise to guard against those threats. But will that be enough? In the foreseeable future attacks w...

Even as cloud and managed services grow increasingly central to business strategy and performance, challenges remain. The biggest sticking point for companies seeking to capitalize on the cloud is data security. Keeping data safe is an issue in any computing environment, and it has been a focus since the earliest days of the cloud revolution. Understandably so: a lot can go wrong when you allow valuable information to live outside the firewall. Recent revelations about government snooping, along with a steady stream of well-publicized data breaches, only add to the uncertainty
