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!

More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smar...

"We build IoT infrastructure products - when you have to integrate different devices, different systems and cloud you have to build an application to do that but we eliminate the need to build an application. Our products can integrate any device, any system, any cloud regardless of protocol," explained Peter Jung, Chief Product Officer at Pulzze Systems, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

The cloud promises new levels of agility and cost-savings for Big Data, data warehousing and analytics. But it’s challenging to understand all the options – from IaaS and PaaS to newer services like HaaS (Hadoop as a Service) and BDaaS (Big Data as a Service). In her session at @BigDataExpo at @ThingsExpo, Hannah Smalltree, a director at Cazena, provided an educational overview of emerging “as-a-service” options for Big Data in the cloud. This is critical background for IT and data professionals...

Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet. This list can only increase because while IoT services should be intuitive and simple to use, the delivery ecosystem is a myriad of potential problems as IoT explodes complexity. So finding a performance issue is like finding the proverbial needle in the haystack.

The idea of comparing data in motion (at the sensor level) to data at rest (in a Big Data server warehouse) with predictive analytics in the cloud is very appealing to the industrial IoT sector. The problem Big Data vendors have, however, is access to that data in motion at the sensor location. In his session at @ThingsExpo, Scott Allen, CMO of FreeWave, discussed how as IoT is increasingly adopted by industrial markets, there is going to be an increased demand for sensor data from the outermos...

"Once customers get a year into their IoT deployments, they start to realize that they may have been shortsighted in the ways they built out their deployment and the key thing I see a lot of people looking at is - how can I take equipment data, pull it back in an IoT solution and show it in a dashboard," stated Dave McCarthy, Director of Products at Bsquare Corporation, in this SYS-CON.tv interview at @ThingsExpo, held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA.

What happens when the different parts of a vehicle become smarter than the vehicle itself? As we move toward the era of smart everything, hundreds of entities in a vehicle that communicate with each other, the vehicle and external systems create a need for identity orchestration so that all entities work as a conglomerate. Much like an orchestra without a conductor, without the ability to secure, control, and connect the link between a vehicle’s head unit, devices, and systems and to manage the ...
