“…Maletic et al [18] proposed an immersive software visualization object-oriented system for comprehension using a CAVE setup. Recently, Fittkau et al [12] evaluated the visualization of software cities using the Oculus Rift for software comprehension tasks. However, none of them elaborate on the grounds that supported their selected medium.…”

“…In the experiment we focused on software comprehension. That is, the cognitive process in which developers learn about a software artifact to accomplish a task [10], and the 3D city visualization technique, which i) has proven to be effective to support software comprehension tasks [11], ii) is available for various media [7], [12], and iii) is easily transferable from one medium to another.…”

Many visualizations have proven to be effective in supporting various software related tasks. Although multiple media can be used to display a visualization, the standard computer screen is used the most. We hypothesize that the medium has a role in their effectiveness. We investigate our hypotheses by conducting a controlled user experiment. In the experiment we focus on the 3D city visualization technique used for software comprehension tasks. We deploy 3D city visualizations across a standard computer screen (SCS), an immersive 3D environment (I3D), and a physical 3D printed model (P3D). We asked twenty-seven participants (whom we divided in three groups for each medium) to visualize software systems of various sizes, solve a set of uniform comprehension tasks, and complete a questionnaire. We measured the effectiveness of visualizations in terms of performance, recollection, and user experience. We found that even though developers using P3D required the least time to identify outliers, they perceived the least difficulty when visualizing systems based on SCS. Moreover, developers using I3D obtained the highest recollection.

“…The software engineering group that developed Syn-chroVis also adapted their ExplorViz software to produce an Oculus Rift implementation with which to interact with a city metaphor [Fitt15]. This implementation allows translation, rotation, and scaling of the model using hand gestures input using a Kinect device.…”

The City Metaphor in Software Visualization

A city metaphor has become a popular method of visualizing properties of program code. This paper provides an overview of research projects that employ this metaphor for a wide range of software engineering tasks. Until now, projects employing the city metaphor have primarily focused on visualizing static and semi-static properties of software repositories, such as understanding how a program's source code structure is changing over time, and who is changing what. This paper compares these existing code cities and suggests likely avenues of future research.

“…Monitoring may provide runtime models [23] for system comprehension [9], trace visualization [4], architecture conformance checks [11], and a landscape control center [12] with performance anomaly detection [3,24]. New perspectives on employing virtual reality [8] and physical models [7] are further explored. Regression benchmarking [31] should be integrated into continuous integration setups [30] of mircoservices.…”

Microservice architectures provide small services that may be deployed and scaled independently of each other, and may employ different middleware stacks for their implementation. Microservice architectures emphasize transaction-less coordination between services, with explicit acceptance of eventual consistency. Polyglott persistence in this context means that the individual microservices may employ multiple data storage technologies. Microservice architectures are "cloud native" allowing for automated and rapid elasticity. Fault-tolerance mechanisms achieve that failures of individual mircroservices do not affect other services thanks to container isolation. Since services can fail at any time, it is important to be able to detect the failures quickly and, if possible, automatically restore services. Essential for success in such a setting is advanced monitoring.In this keynote, I discuss how mircoservices support scalability for both, runtime performance and development performance, via polyglott persistence, eventual consistency, loose coupling, open source frameworks, and continuous monitoring for elastic capacity management.
