FaaS-Oriented *** Applications in an RPC Approach Using the node2FaaS Framework

IEEE ACCESS 2023年 11卷 112027-112043页

The Function-as-a-Service (FaaS) service model has aroused great interest since its introduction in the context of cloud computing. Although FaaS can be used to perform isolated tasks, it is in the composition of applications that this service model can promote significant performance improvements. This work presents an evolution in the node2FaaS framework, whose objective is to assist in the conversion of originally monolithic *** applications to work with FaaS in the Remote Procedure Call (RPC) communication mechanism. The new implementations in the node2FaaS framework allowed new experiments to be conducted. Those showed significant gains in runtime for applications with CPU-bound, memory-bound, I/O-bound characteristics, especially for a Bioinformatics application that aims to align genetic sequences.

The *** runtime, in combination with node Package Manager (NPM), is a popular ecosystem for building server-side web applications. Both JavaScript's flexible and dynamic character and the vast amount of NPM libraries available can speed up the development of web applications. However, JavaScript and *** lack security mechanisms and abstractions. Despite the numerous language-based approaches proposed to protect JavaScript applications, no work supports applicationlevel and business -level security properties. This means that in order to achieve both application-level and business -level security, developers are forced to rely on multiple different, unintegrated and incompatible tools and mechanisms. In this paper, we present BRIGADIER, an interactive security testing framework for *** applications that enables the specification of both application-level and business -level security policies. BRIGADIER provides developers with a Datalog-based policy specification language that features close interoperability with running JavaScript programs under test. Input JavaScript programs are instrumented to emit relevant application events sent to a Datalog engine resulting from the compilation of the policies. We exhibit BRIGADIER'S expressiveness by implementing three case studies from the literature. We also assess BRIGADIER'S performance overhead on server-side applications. In our benchmarks, we observed a slowdown factor ranging from similar to 1.2x to similar to 3x, which is acceptable for a testing scenario.

We examine the implications of end-to-end web application development, in the social web era. The paper describes a distributed architecture, suitable for modern web application development, as well as the interactivity components associated with it. Furthermore, we conducted a series of stress tests, on popular server side technologies. The PHP/Apache stack was found inefficient to address the increasing demand in network traffic. Nginx was found more than 2.5 times faster in input/output (I/O) operations than Apache, whereas *** outperformed both. ***, although excellent in I/O operations and resource utilization, was found lacking in serving static files using its built in HTTP server, while Nginx performed great at this task. So, in order to address efficiency, an Nginx server could be placed in-front and proxy static file requests, allowing the *** processes to only handle dynamic content. Such a configuration can offer a better infrastructure in terms of efficiency and scalability, replacing the aged PHP/Apache stack. Furthermore we have found that building cross platform applications based on web technologies, is both feasible and highly productive, especially when addressing stationary and mobile devices, as well as the fragmentation among them. Our study concludes that *** offers client-server development integration, aiding code reusability in web applications, and is the perfect tool for developing fast, scalable network applications.

This paper presents a new approach to develop remote practices for Systems Engineering and Automatic Control laboratories based on Easy JavaScript Simulations (EjsS), Raspberry Pi and ***. EjsS is used to create a JavaScript and HTML5 laboratory front-end that lets Leachers and students parametrize and observe the behavior of the controllers/systems under study from the web-browsers of their tablets and smartphones. The Raspberry Pi, a low-cost single-board computer, is in charge of running 1) the C program that closes the control loop over the selected plant and 2) the JavaScript laboratory web server that hosts the laboratory front-end and communicates it with the controller. Finally, the JavaScript development and runtime platform *** is used 1) to develop and run the Javascript laboratory web sever within the Raspberry Pi and 2) to support the communications between the laboratory front-end and server. The new strategy, tested over a Proportional/Integral/Differential (PID)) controller for a vertical mono-rotor plant, provides low-cost real-time support to the controller and friendly remote access from mobile devices to the practices for the students.

Large scale, high concurrency, and vast amount of data are important trends for the new generation of website. *** becomes popular and successful to build data-intensive web applications. To study and compare the performance of ***, Python-Web and PHP, we used benchmark tests and scenario tests. The experimental results yield some valuable performance data, showing that PHP and Python-Web handle much less requests than that of *** in a certain time. In conclusion, our results clearly demonstrate that *** is quite lightweight and efficient, which is an idea fit for I/O intensive websites among the three, while PHP is only suitable for small and middle scale applications, and Python-Web is developer friendly and good for large web architectures. To the best of our knowledge, this is the first paper to evaluate these Web programming technologies with both objective systematic tests (benchmark) and realistic user behavior tests (scenario), especially taking *** as the main topic to discuss.
