Model-driven development for Microservices : A domain-specific modeling language for KubernetesJohansson, Daniel January 2022 (has links)
In the digital age that we live in today, we are dependent on numerous web applications or services, from dealing with banking, booking air flights, and handling our taxes. We expect these applications and services to support high availability, data loss prevention, and fast response time. Microservices is a design pattern to support faster software change, and it also supports other non-functional attributes such as scalability and high availability. One way to deploy your software as microservices is to use containers and deploy them on a container cluster such as Kubernetes. The public opinion about writing Kubernetes deployment files is that it is complex and repetitive writing. This project aims to see how model-driven development can assist with the creation of the Kubernetes deployment files. To see how model-driven development can assist in the creation of Kubernetes files. The project will implement a domain-specific modeling language for Kubernetes, and the language should be able to model the application's desired states. And by using model transformation, the tool can generate Kubernetes deployable files.

A Domain-Specific Design Tool for Verifying Spacecraft System BehaviorVenigalla, Sravanthi 01 December 2009 (has links)
In this report we present a graphical tool, Behavioral Analysis of Spacecraft Systems (BASS), that can be used by spacecraft designers to perform system-level behavioral analysis of small satellites. The domain-specific spacecraft meta-model is created in the visual modeling tool Generic Modeling Environment (GME) such that spacecraft designs created using the meta-model appear familiar to the spacecraft designers. Users can model scenarios that are to be verified for the design in BASS. The graphical models are assigned formal semantics facilitating the creation of formally verifiable spacecraft models. The C++ application that translates the modeling objects to equivalent mathematical representation of interest is called BASS Interpreter and is bound to the meta-model. BASS Interpreter that generates Communicating Sequential Processes (CSP) semantics for the visual spacecraft models is supported in the current work. The model-checker for CSP called Failures Divergences and Refinement (FDR) is run to explore the state-space of the spacecraft process model to comment on the design. We demonstrate the feasibilty and advantage of incorporating BASS into initial design phases of small satellite development by successfully verifying the design of Tomographic Remote Observer of Ionospheric Disturbances (TOROID).

Previous issue date: 2016-03-04 / Cada vez mais se evidencia uma maior escassez de recursos e uma disputa por
espaços físicos, em decorrência da crescente e demasiada concentração populacional nas
grandes cidades. Nesse âmbito, surge a necessidade de soluções que vão de encontro à
iniciativa de “Cidades Inteligentes" (Smart Cities). Essas soluções buscam centralizar o
monitoramento e controle, para auxiliar no apoio à tomada de decisão. No entanto, essas
fontes de TICs formam estruturas complexas e geram um grande volume de dados, que
apresentam enormes desafios e oportunidades.
Uma das principais ferramentas tecnológicas utilizadas nesse contexto é o Complex
Event Processing (CEP), o qual pode ser considerado uma boa solução, para lidar com o
aumento da disponibilidade de grandes volumes de dados, em tempo real. CEPs realizam
captação de eventos de maneira simplificada, utilizando linguagem de expressão, para
definir e executar regras de processamento. No entanto, apesar da eficiência comprovada
dessas ferramentas, o fato das regras serem expressas em baixo nível, torna o seu uso
exclusivo para usuários especialistas, dificultando a criação de soluções.
Com intuito de diminuir a complexidade das ferramentas de CEP, em algumas
soluções, tem-se utilizado uma abordagem de modelos Model-Driven Development (MDD),
a fim de se produzir uma camada de abstração, que possibilite criar regras, sem que
necessariamente seja um usuário especialista em linguagem de CEP. No entanto, muitas
dessas soluções acabam tornando-se mais complexas no seu manuseio do que o uso
convencional da linguagem de baixo nível.
Este trabalho tem por objetivo a construção de uma Graphic User Interface (GUI)
para criação de regras de CEP, utilizando MDD, a fim de tornar o desenvolvimento mais
intuitivo, através de um modelo adaptado as necessidades do usuário não especialista. / Nowadays is Increasingly evident a greater resources scarcity and competition for
physical space, in result of growing up and large population concentration into large cities.
In this context, comes up the necessity of solutions that are in compliance with initiative of
smart cities. Those solutions seek concentrate monitoring and control, for help to make
decisions. Although, this sources of information technology and communications (ITCs)
forming complex structures and generates a huge quantity of data that represents biggest
challenges and opportunities.
One of the main technological tools used in this context is the Complex Event
Processing (CEP), which may be considered a good solution to deal with increase of the
availability and large volume of data, in real time. The CEPs realizes captation of events in
a simple way, using expressive languages, to define and execute processing rules. Although
the efficient use of this tools, the fact of the rules being expressed in low level, becomes
your use exclusive for specialists, difficulting the creation of solutions.
With the aim of reduce the complexity of the CEPs tools, solutions has used an
approach of models Model-Driven Development (MDD), in order to produce an abstraction
layer, that allows to create rules, without necessarily being a specialist in CEP languages.
however, many this tools become more complex than the conventional low level language
approach.
This work aims to build a Graphic User Interface (GUI) for the creation of CEP rules,
using MDD, in order to a more intuitive development, across of the adapted model how
necessities of the non specialist users.

Transforming Mission Space Models To Executable Simulation ModelsOzhan, Gurkan 01 September 2011 (has links) (PDF)
This thesis presents a two step automatic transformation of Field Artillery Mission Space Conceptual Models (ACMs) into High Level Architecture (HLA) Federation Architecture
Models (FAMs) into executable distributed simulation code. The approach followed in the course of this thesis adheres to the Model-Driven Engineering (MDE) philosophy. Both
ACMs and FAMs are formally defined conforming to their metamodels, ACMM and FAMM, respectively. ACMM is comprised of a behavioral component, based on Live
Sequence Charts (LSCs), and a data component based on UML class diagrams. Using ACMM, the Adjustment Followed by Fire For Effect (AdjFFE) mission, which serves as the source model for the model transformation case study, is constructed. The ACM to FAM transformation, which is defined over metamodel-level graph patterns, is carried out
with the Graph Rewriting and Transformation (GReAT) tool. Code generation from a FAM is accomplished by employing a model interpreter that produces Java/AspectJ code. The
resulting code can then be executed on an HLA Run-Time Infrastructure (RTI). Bringing a fully fledged transformation approach to conceptual modeling is a distinguishing feature of
this thesis. This thesis also aims to bring the chart notations to the attention of the mission space modeling community regarding the description of military tasks, particularly their
communication aspect. With the experience gained, a set of guidelines for a domainindependent transformer from any metamodel-based conceptual model to FAM is offered.

Sričiai orientuotos informacinės sistemos kūrimo metodikos tyrimas ir taikymas / Research of DSL for information system developmentStrakšys, Justinas 04 March 2009 (has links)
Viena iš naujausių sistemų kūrimo metodikų – sričiai orientuotas modeliavimas (angl. domain specific modeling). Ji paremta sričiai orientuotos kalbos kūrimu ir jos panaudojimu sistemos kūrimui. Ši metodika leidžia sistemos kūrimui naudoti sąvokas, artimas probleminei sričiai, kas padidina abstrakcijos lygi projektavimo metu. Srities sąvokos aptariamos ir įvardinamos kartu su ekspertais ar paprastais darbuotojais, dirbančiais analizuojamoje srityje, ir nebūtinai išmanančiais sistemų kūrimo metodus. Ši metodika leidžia sistemos projektuotojui lengviau susikalbėti su užsakovais, nes modeliuose figūruojančios sąvokos yra užsakovui suprantamos ir aiškios. / Domain Specific Modeling is a software engineering methodology for designing and developing information systems. It involves systematic use of a graphical domain specific language (DSL) to represent the various facets of a system. DSM languages tend to support higher-level abstractions than general purpose modeling languages, so they require less effort and fewer low-level details to specify a given system which is very important nowadays, when the functionality of information system must be maximized with minimum development time and cost. This paper compares usage of DSL for information system development with other two, most often used methodologies for this purpose: MDA and usage of UML. It gives basic advantages and disadvantages of DSL and DSM usage, describes differences of DSL (DSM), UML and MDA. This paper also describes usage of DSM methodology (creating DSL and using it for software development) for creating information system. It covers main steps of creation process’s: describing the domain concepts, describing the artifacts that are planning for the DSL, building domain model, building the designer for DSL, building the artifact generator, implementing validations and constraints, testing and deploying the DSL.

Approche Domain-Specific Modeling pour l'opérationnalisation des scénarios pédagogiques sur les plateformes de formation à distanceAbedmouleh, Aymen 11 July 2013 (has links) (PDF)
Ce travail de recherche porte sur la spécification et l'opérationnalisation des scénarios pédagogiques sur les plateformes de formation à distance dans une perspective d'ingénierie et de réingénierie des EIAH (Environnements Informatique pour l'Apprentissage Humain). En se situant dans une approche centrée plateformes, nous supposons que les plateformes disposent de leur propre paradigme de conception. Pour cela, nous proposons aux développeurs et à la communauté de développement des plateformes un processus spécifique d'identification et d'explicitation du langage de conception pédagogique des plateformes de formation par le biais d'un métamodèle. Nous exploitons l'approche outillée Domain-Specific Modeling comme cadre pratique pour le développement de langages et d'outils de conception graphiques basés sur le métamodèle du langage de conception pédagogique. Afin de répondre à des besoins récurrents d'opérationnalisation de scénarios pédagogiques, nous utilisons également ce métamodèle pour la spécification des modules d'import/export intégrés au sein des plateformes. Ces modules permettent d'opérationnaliser les scénarios conformes au langage identifié et également d'exporter les scénarios existants sur les plateformes afin de permettre leur adaptation par les outils développés. Nous avons expérimenté nos propositions théoriques sur deux plateformes de formation Moodle et Ganesha. Enfin, nous avons vérifié la cohérence de notre approche par la mise à l'essai des outils développés. Par le biais de notre approche, nous favorisons une opérationnalisation de ces scénarios sans pertes d'information ni de sémantique.

By positioning in an approach centered LMS instructional design, we suppose that each learning platform has its own instructional design language. So, we propose a specific process for its identification and formalization through a metamodel. Based on this metamodel, we use the Domain-Specific Modeling approach as a practical framework for the development of languages and graphical design tools. This metamodel is also used to specify the import/export modules that are integrated into the platforms in order to meet the recurring needs of the operationalization of learning scenarios. These modules allow also the extraction of the existing scenarios on platforms to enable their adaptation on the developed tools. Our theoretical propositions have been tested on two learning platforms: Moodle and Ganesha. On the other hand, the consistency of our approach was checked and validated by implementing and testing the developed tools. Through our approach, we promote scenarios operationalization without loss of information or semantics.

Collaborative Construction of Telecommunications Services. An Enterprise Architecture and Model Driven Engineering MethodCHIPRIANOV, Vanea 16 January 2012 (has links) (PDF)
In the context of world economies transitioning to services, telecommunications services are the primary means of communication between different economic entities and are therefore essential. The focus on the end consumer, the convergence with the Internet, the separation between the software and the hardware implementing a service, and the telecommunications market deregulation have led to a revolution and a new era in the telecommunications industry. To meet these challenges, former national telecommunications providers have to reduce the construction time, from months to days, while affecting non-negatively other parameters (e.g., cost, quality of service, quality of experience) of new telecommunications services. To tackle this broad theme, we propose a telecommunications service construction process, the software tools that are to be used in this process and a tool building process to build them. The telecommunications service construction process reflects current practices in the telecommunications industry. As such, it should be (easily) accepted by practitioners. The software tools (i.e., Domain Specific Modeling Languages designed as profiles of an Enterprise Architecture Modeling Language, graphical editors, code generators, Off the Shelf network simulators, a collaboration Design Rationale Domain Specific Modeling Language) help telecommunications providers face the challenges. The tool building process relies on models and provides a high automation degree, hence software tools can be build more rapidly. We illustrate the telecommunications service construction process and the tools using a multimedia conferencing service. Our proposals contribute to reducing the construction time of new telecommunications services, while providing the possibility of improved quality of service and increased involvement of the consumer. Faster provisioning of new telecommunications services, that better answer the consumers¿ needs, will increase the rate of development of new economic services in general, and will ultimately have a positive impact on world economic development.

Ingéniérie dirigée par les modèles pour la gestion de la variabilité dans le test d'applications mobiles / Model-Driven Engineering for Variability Management in Mobile Application TestingRidene, Youssef 23 September 2011 (has links)
L'engouement du grand public pour les applications mobiles, dont le nombre ne cessede croître, a rendu les utilisateurs de plus en plus exigeants quant à la qualité de cesapplications. Seule une procédure de test efficace permet de répondre à ces exigences.Dans le contexte des applications embarquées sur téléphones mobiles, le test est unetâche coûteuse et répétitive principalement à cause du nombre important de terminauxmobiles qui sont tous différents les uns des autres.Nous proposons dans cette thèse le langage MATeL, un DSML (Domain-Specific ModelingLanguage) qui permet de d’écrire des scénarios de test spécifiques aux applicationsmobiles. Sa syntaxe abstraite, i.e. un méta modèle et des contraintes OCL, permet auconcepteur de manipuler les concepts métier du test d'applications mobiles (testeur, mobileou encore résultats attendus et résultats obtenus). Par ailleurs, il permet d'enrichirces scénarii avec des points de variabilité qui autorisent de spécifier des variations dansle test en fonction des particularités d'un mobile ou d'un ensemble de mobiles. La syntaxeconcrète de MATeL, qui est inspirée de celle des diagrammes de séquence UML,ainsi que son environnement basé sur Eclipse permettent à l'utilisateur de concevoir desscénarii relativement facilement.Grâce à une plateforme de test en ligne construite pour les besoins de notre projet,il est possible d'exécuter les scénarii sur plusieurs téléphones différents. La démarcheest illustrée dans cette thèse à travers des cas d'utilisation et des expérimentations quiont permis de vérifier et valider notre proposition. / Mobile applications have increased substantially in volume with the emergence ofsmartphones. Ensuring high quality and successful user experience is crucial to the successof such applications. Only an efficient test procedure allows developers to meet these requirements. In the context of embedded mobile applications, the test is costly and repetitive. This is mainly due to the large number of different mobile devices. In this thesis, we describe MATeL, a Domain-Specific Modeling Language (DSML) for designing test scenarios for mobile applications. Its abstract syntax, i.e. a meta model and OCL constraints, enables the test designer to manipulate mobile applications testing concepts such as tester, mobile or outcomes and results. It also enables him/her to enrich these scenarios with variability points in the spirit of Software Product-Line engineering, that can specify variations in the test according to the characteristics of one mobile or a set of mobiles. The concrete syntax of MATeL that is inspired from UML sequence diagrams and its environment based on Eclipse allow the user to easily develop scenarios. MATeL is built upon an industrial platform (a test bed) in order to be able to run scenarios on several different phones. The approach is illustrated in this thesis through use cases and experiments that led to verify and validate our contribution.
