Closing the Gap between Web Applications and Desktop Applications by Designing a Novel Desktop-as-a-Service (DaaS) with Seamless Support for Desktop Applications

An increasing transformation from locally deployed applications to remote web applications has occurred for about two decades. Nevertheless, abandoning established and essential Windows or Linux desktop applications is in many scenarios impossible. This paper describes and evaluates existing Desktop-as-a-Service solutions and the components required for developing a novel DaaS. Based on the conclusions and findings of this analysis, the paper describes a novel approach for a Desktop-as-a-Service solution that enables, as a unique characteristic, the deployment of non-modified Linux and Windows applications. The interaction with these applications is done entirely through a browser which is unusual for remote interaction with Windows or Linux desktop applications but brings many benefits from the user's point of view because installing any additional client software or local virtualization solution becomes unnecessary. A solution, as described in this paper, has many advantages and offers excellent potential for use in academia, research, industry, and administration

Single server-side and multiple virtual server-side architectures: Performance analysis on Proxmox VE for e-learning systems

At this time, almost all educational institutions use the e-learning system to support learning. The factor that plays the most role in the comfortable use of a system is the performance aspect. This type of single-server architecture is very commonly applied in building a system, but this system is actually less efficient because it does not pay attention to the level of availability. In this study, a server architecture was built in the form of multiple virtual servers utilizing virtualization on Proxmox by applying reverse proxy techniques and storage clustering to increase system availability in building an e-learning Moodle system. The design of multiple virtual server architectures uses prepare, plan, design, implementation, test and optimization methodologies. The results of the research on the testbed and test plan show that the multiple virtual server architecture has superior availability compared to the single server architecture. Based on the User Behavior Modeling Performance (UBMP) test results, the multiple virtual server architecture is also superior, with a maximum value of 100 concurrent users on the multiple virtual server-side architecture, where the availability level is 80.25%, while on the single server, it is lower with a value of 80 users and an availability level of 78.4%

TEKNOLOGI MACHINE LEARNING PADA SISTEM PENDUKUNG PENELITIAN RSYS (RESEARCH SUPPORT SYSTEM)

Students who are still unfamiliar with the revising process focus on the local level, such as grammar, spelling, punctuation, and sentence level. Meanwhile, students who are experts focus on the global level, such as focusing on improving writing goals, ideas, and meanings. When making revisions, students become too focused on the local level rather than the global level. Comments for the local level are ineffective as a guide in the revision process. Therefore, this study aims to build machine learning-based software with the ANN method to classify global or local comments. This study uses a design research methodology with the SDLC model of prototyping. The results show that the RSYS software was successfully built with machine learning accuracy in classifying 19 comments, obtained from 2 documents, with a 95: 0.5 ratio, 94.74%. Whereas in alpha testing, it was stated that the functionality of the RSYS system and machine learning was considered to be functioning correctly. For beta testing, the largest percentage was 85% for ease of operation and convenience in using the application, 75% for website display and navigation availability

Testbed para el estudio de la virtualización de las funciones de red NFV

Diseñar y desplegar un testbed donde permita estudiar el comportamiento de NFV, generando una topología que evidencie el desempeño de las funciones de red virtualizadas.El presente trabajo de titulación presenta un Testbed para tecnología NFV con Open Source MANO (OSM), que es una plataforma de gestión y orquestación (MANO) de código abierto para redes virtualizadas. Esta plataforma proporciona los medios para gestionar y controlar funciones de red virtualizadas (VNFs) y servicios de red en un entorno virtual. Es así como, para este proyecto se utiliza OSM en combinación con las plataformas OpenStack y OpenDaylight, que permite crear un entorno de red más centralizado, el cual despliega y gestiona configuraciones de red complejas propias para la virtualización de las funciones de red. Por lo tanto, en este apartado se detalla una descripción general de alto nivel de cómo OSM, OpenStack y OpenDaylight pueden utilizarse para virtualizar funciones de red. Es decir, en primer lugar, se crea una VNF utilizando OSM. La creación de esta VNF es simple a través de plantillas predefinidas o cargando un paquete VNF existente. Seguidamente, la VNF se despliega sobre OpenDaylight, que proporciona la infraestructura y los recursos necesarios para ejecutar la VNF. Con OpenStack se logra gestionar la infraestructura de red y controlar el flujo de tráfico dentro de la red virtualizada, es decir, crear, gestionar y eliminar VNFs. Y por último con OSM se supervisa y gestiona la red virtualizada en su conjunto creada por VNFs. Por lo tanto, el testbed desplegado proporciona herramientas para proveer, supervisar y escalar funciones de red virtualizadas (VNFs) con los recursos de red, según sea necesario.Ingenierí
