Introduction to Services 20-Apr-17 Service Basics [Title of the course] Introduction to Services SOA : Services Oriented Architecture OOP complement Used in processing and communicating with Services. Objectives Productive Reactive Capable of managing responsibility On peut citer la SNCF, qui a mis en place une architecture de type SOA pour son système de réservation (recherche d'horaire, demande de tarif, réservation...) qui prend en charge à la fois les terminaux des guichets des agences et gares, et les sollicitations de son site web de commande en ligne Les architectures SOA reposent principalement sur l’utilisation d’interface d’invocation (SOAP) et de vocabulaire de description de données (WSDL et XML) qui doivent être communs à l’ensemble des agents (fournisseurs de services et utilisateurs de services). la notion de SOA (pour architecture orientée services) définie un modèle d'interaction applicative mettant en oeuvre des connexions en couplage lâche entre divers composants logiciels (ou agents). Ici, on entend par "service" une action exécutée par un composant "fournisseur" à l'attention d'un composant "consommateur", basé éventuellement sur un autre système.

Introduction to Services 20-Apr-17 Service Basics [Title of the course] Introduction to Services SOA : Services Oriented Architecture Based on 4 principals: The borders are explicit. The services are independent of one another. Contracts are shared, but not objects. Semantics are dictated by rules. Les frontières d’un service sont explicites : Le client et le développeur sont conscients que l’appel aux méthodes distantes se fait à travers des messages et passent par le réseau. Cela permet par exemple d’utiliser d’autres méthodes que la classique demande/réponse synchrone qui est utilisée pour simuler l’appel à une méthode locale. Les services sont indépendants : Un service est autonome, et donc ce sont les clients qui doivent s’adapter lors de l’évolution d’un service à une nouvelle version. L’avantage est qu’ainsi l’interaction entre plusieurs services se fait naturellement et les services s’adaptent entre eux aux nouvelles contraintes. Il est donc important pour le service de gérer les erreurs, surtout pour les clients qui ne seraient pas à jour. L’utilisation d’un service est décrite à l’aide d’un contrat : Le contrat est un représenté par un fichier XML. Il contient entre autres la structure des informations contenues dans les messages entrant et sortant. Ce contrat peut contenir de commentaires. Le contrat est souvent utilisé pour définir la construction des classes du client. La sémantique est dictée par des règles : La sémantique, le format des messages et la stratégie d’accès au service peuvent être spécifiés (si nécessaire) dans le contrat par des règles. Ainsi, un service peut définir qu’il n’accepte que les messages entrants encryptés d’une certaine façon, ou encore qu’il n’est accessible que dans une tranche horaire définie, etc. La définition de cette sémantique peut être consommée par un framework, pour que l’encryptage des données se fasse automatiquement sans intervention du développeur du client, par exemple.

Introduction to Services 20-Apr-17 Service Basics [Title of the course] Introduction to Services Advantages and disadvantages of Services Advantages: Interoperability Simplified access Accessible data exchange format Centralized arrangement Disadvantages: Poor performance Ever-changing standards Avantages : Interopérabilité : Un service web développé en .Net pourra être consommé en Perl, en Java, en PHP… Accès simplifié : L’utilisation d’HTTP comme protocole d’accès aux services web évite les problèmes liés à l’utilisation de firewalls Format d’échange accessible : Les échanges entre le client et le service web est au format texte, ce qui facilite la compréhension et l’exploitation Mise à disposition centralisée : Services permettent de mettre à disposition à un seul endroit un composant utilisé en interne ou de le fournir à des prestataires ou des clients Inconvénients : Services ne sont pas performants : L’utilisation de format texte, des standards du web et la compatibilité entre plate formes sont à ce prix Une technologie en perpétuelle évolution : Les normes et les fonctionnalités ne cessent d’évoluer Copyright © 2004-2005 NameOfTheOrganization.

20-Apr-17 Service Basics [Title of the course] SOAP Protocol Allows the transmission of structured and formatted data in messages between 2 distant objects. Standard defined by W3C Based on XML Current version: 1.2 Il permet la transmission de messages entre objets distants, ce qui veut dire qu'il autorise un objet à invoquer des méthodes d'objets physiquement situés sur une autre machine. Le transfert se fait le plus souvent à l'aide du protocole HTTP, mais peut également se faire par un autre protocole, comme SMTP. Copyright © 2004-2005 NameOfTheOrganization. All rights reserved.

UDDI Directory What is it? 20-Apr-17 Service Basics [Title of the course] UDDI Directory What is it? Universal Description, Discovery and Integration It is a directory of Services. which is a Service itself. It contains information on service providers (contracts, activities…) description on services (as part of the WSDL contract) Une fois qu'un Services est développé, il faut publier sa description et faire un lien vers elle dans un catalogue UDDI (Universal Description, Discovery and Integration), de sorte que les utilisateurs potentiels puissent le trouver. Quand un utilisateurs souhaite utiliser le service, il fait une demande de son fichier WSDL afin de connaître son emplacement, les appels de fonctions et comment y accéder. A partir de cela, il peut composer, par exemple, une requête SOAP (Simple Object Access Protocol) vers l'ordinateur du service. Tout ce parcours peut évidemment être automatisé à l'aide d'outils reconnaissant WSDL, et permet ainsi d'intégrer de nouveaux services pratiquement sans devoir entrer de nouveau code.
