This article is based on the experience of Jan Swaelens, Software Architect at Sofico. He is responsible for automatic performance testing of the company's new web platform based on GWT and SmartGWT. Sofico is specialized in software solutions for automotive finance, leasing, fleet and mobility management companies.
Choosing GWT and SmartGWT over Other Technologies
About two years ago Sofico started a project to replace its rich desktop application (built with PowerBuilder) with a browseribased rich Internet application. The developers selected GWT and SmartGWT as core technologies to leverage their in-house Java expertise because they believed in the potential of what these (fairly) new technologies had to offer. Their goal was to replace the existing desktop client with a new one that ran in a browser. Their eyes where set on a better user experience and high degree of customization possibilities to give their customers the flexibility and adaptability that they need to run their businesses.
Need End-to-End Visibility into GWT Black Box
GWT was a great choice as they could soon deliver the first basic version. The problems started when trying to figure out what was actually going on in these frameworks in order to analyze performance problems reported by the first testers.
Requirement #1: Browser to Database Visibility to "understand" what's going on
Do you know what really happens when a page of a GWT application is loaded? No?! Neither did the developers from Sofico. Getting insight into the "Black Box" was therefore the first requirement because they wanted to understand: what really happens in the browser, how many resources are downloaded from the web server, which transactions make it to the app server, what requests are cached, where is it cached and how the business logic and data access layer implementation impacts end user experience.
The following screenshots show the current implementation using dynaTrace (sign up for the free trial), which gives the developers full visibility from the browser to the web, app and database server. The Transaction Flow visualizes how individual requests or page loads and services by the different application tiers are processed.
End-to-End Visibility gave the developers more insight into how their GWT Application really works and what happens when pages are loaded or users interact with certain features.
Developers love the timeline view as it is easy to see what work is done by the browser, where performance hotspots are and even provides screenshots at certain events

Requirement #3: Correlated Server-Side Performance Data
Requirement #4: Automation, Automation, Automation
Next Step: Real User Monitoring
After test automation comes production: You want to make sure to also monitor your real users and catch problems not found in testing

Predictive analytics tools monitor, report, and troubleshoot in order to make proactive decisions about the health, performance, and utilization of storage. Most enterprises combine cloud and on-premise storage, resulting in blended environments of physical, virtual, cloud, and other platforms, which justifies more sophisticated storage analytics. In his session at 18th Cloud Expo, Peter McCallum, Vice President of Datacenter Solutions at FalconStor, discussed using predictive analytics to mon...

Today we can collect lots and lots of performance data. We build beautiful dashboards and even have fancy query languages to access and transform the data. Still performance data is a secret language only a couple of people understand. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. Some of these people have never used a monitoring tool before. They have a question on their mind like “How is my application doing” but no id...

In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.

All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of Soli...

We are always online. We access our data, our finances, work, and various services on the Internet. But we live in a congested world of information in which the roads were built two decades ago. The quest for better, faster Internet routing has been around for a decade, but nobody solved this problem. We’ve seen band-aid approaches like CDNs that attack a niche's slice of static content part of the Internet, but that’s it. It does not address the dynamic services-based Internet of today. It does...

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 ...
