Many organizations have embraced, or are considering, the benefits of cloud computing – speed, flexibility, increased expertise, shared workload, reduced costs, etc. The benefits are many – but so are the risks. What are the threats to cloud security? Which parties assume responsibility for securing the environment? What about the data? Which type of cloud deployment offers superior security benefits?

Oui, je sais, encore un acronyme en aaS !
Par curiosité j’ai fait une recherche "Praas" sur Bing et Google, actualité oblige !
Le moins que l’on puisse dire, et que les résultats obtenus sont ... très différents !
Pour ceux que cela intéresse, je vous conseille d’utiliser l’outil “blackdog” qui exécute votre recherche sur Google et Bing et vous propose les deux sur la même page de votre navigateur.
J’ai ainsi appris que Praas est un produit “magique” de médecine naturelle, qui s’appuie sur une démarche très ancienne de la médecine indienne, nommée Ayurveda. (l’article de Wikipédia sur Ayurveda est passionnant.)
Revenons à notre monde de la technologie, du Cloud Computing.
Pourquoi parler de PRaaS ? Quelles différences avec les solutions SaaS ? C’est ce que je vous propose de découvrir.
PRaaS, PRocessus as a Service : un essai de définition La lecture d’un texte récent, sur l’excellent blog de mon ami Phil Wainewright, a été le déclic qui m’a aidé à formaliser une idée sur laquelle je travaille depuis quelques années.
Dans son texte “Thinking Beyond SaaS As We Know It” (en réfléchissant au-delà du SaaS tel qu’on le connait”), Phil présente une entreprise, “Service Channel”, qui propose, comme un service sur le Cloud, la gestion complète de la sous-traitance de l’entretien d’établissements géographiquement répartis.
C’est un processus complexe, très spécialisé, et qui consomme beaucoup de ressources dans les grandes entreprises.
Quelles sont les compétences nécessaires pour créer “Service Channel” ?
- Une équipe d’informaticiens pour construire ce service sur le Cloud, oui, bien sûr, mais... ce n’est pas l’essentiel !
- En priorité une équipe de professionnels de ces métiers, qui connaissent sur le bout des doigts toutes ses spécificités et ses complexités, pour le modéliser et être capables d’en faire un “service” utilisable par des milliers d’entreprises.
C’est d’ailleurs l’un des points clefs de leur compétitivité ; on peut lire sur leur site : “Every member of our team has a deep understanding of the challenges that facility managers and contractors face every day...” (Chaque membre de notre équipe a une connaissance approfondie des difficultés rencontrées tous les jours par les gestionnaires et les sous-traitants...)
Et si “Service Channel” était un exemple de .... PRaaS, PRocessus as a Service ?
Je vous propose donc une première définition d’un PRaaS :
Un PRaaS possède quatre caractéristiques de base :
- Un service disponible sur le Cloud.
- Propose une réponse complète pour gérer l’intégralité d’un processus.
- Concerne non seulement l’entreprise, mais aussi des acteurs externes, clients, fournisseurs ou prestataires.
- Est utilisable directement par des personnes des métiers concernés, sans nécessiter l’intervention d’informaticiens de l’entreprise.
PRaaS, processiels et BPO (Business Process Outsourcing)
Pourquoi promouvoir PRaaS, un concept de plus, dans notre monde informatique qui est très friand de néologismes et de sigles ?
Il y a une excellente raison pour le faire ; je suis persuadé que c’est une innovation forte, qui va jouer un rôle clef au cours des cinq prochaines années.
PRaaS se situe au confluent de trois mouvements majeurs : - BPO, Business Process Outsourcing. Depuis des dizaines d’années, les entreprises ont externalisé des activités “Back-office” à des sociétés spécialisées, souvent situées en Inde, en Afrique du Nord ou dans des pays de l’Est de l’Europe.
- L’émergence de processiels, progiciels construits autour d’un processus, thème que j’ai traité ily a peu.
- L’arrivée du Cloud Computing, qui met à disposition des entreprises et des éditeurs de solutions informatiques de la puissance informatique infinie, fiable et sécurisée, à des coûts très compétitifs. Il devient maintenant possible de cumuler les avantages des trois démarches ... dans un PRaaS :
- L’entreprise cliente peut accélérer sa démarche BPO en s’appuyant sur une offre PRaaS qui va exploser, plus modulaire, capable de prendre en charge des processus plus spécialisés et très orientés “Front-office”.
- Une entreprise qui possède une forte expertise métier dans un processus spécialisé peut construire un PRaaS performant, rapidement, et qui sera potentiellement disponible pour des clients dans le monde entier.
Amiando en est un bon exemple : ce PRaaS prend en charge toute la réalisation d’un événement ou d’une conférence. Il a été utilisé pour plus de 50 000 événements, et le service est déjà disponible en Français, Anglais, Allemand et Espagnol.
- Le Cloud fournit l’infrastructure informatique qui permet d’héberger cette famille de services, en libérant les développeurs de PRaaS de contraintes de performances et d’investissements lourds dans des infrastructures informatiques spécifiques.
Une autre définition du PRaaS devient possible :
Un PRaaS, ou quand un BPO rencontre un Processiel sur le Cloud.
PRaaS, un composant de plus dans la “nébuleuse” Cloud Computing
L’arrivée rapide de solutions PRaaS accroît encore plus l’intérêt du Cloud Computing pour les entreprises de toutes tailles, de tous les secteurs d’activités. Aujourd’hui, une DSI est l’interlocutrice principale des acteurs du Cloud ; elle met en œuvre les trois composants principaux actuels du Cloud Computing :
- IaaS, Infrastructures as a Service = mise à disposition de ressources telles que serveurs ou capacité de stockage. AWS, Amazon Web Services, est aujourd’hui le leader incontesté de l’IaaS.
- PaaS, Platform as a Service = outils à la disposition des équipes de développement, pour écrire des programmes en Java, Phyton ou autres langages. Google App Engine ou Force.com en sont deux bons exemples.
- SaaS, Software as a Service. C’est la brique la plus connue du Cloud. Jeff Kaplan publie depuis 2 ans SaaS Showplace, un catalogue qui contient aujourd’hui plus d’un millier de solutions SaaS. Ce quatrième composant du Cloud que je propose aujourd’hui, PRaaS, est le premier qui s’adresse directement aux responsables métiers d’une entreprise.
Ceci ne veut pas dire, au contraire, que la DSI ne peut jouer un rôle utile, en accompagnant les métiers et en aidant la nouvelle solution PRaaS à dialoguer avec les applications existantes.
C’est par contre l’amorce d’un tournant majeur dans la jeune histoire de l’informatique : pour la première fois, les solutions deviennent suffisamment “industrielles” pour que les responsables métiers soient capables de les choisir, déployer et utiliser directement, seuls.
Outils de construction de processus spécifiques
Pour compléter ce panorama, je souhaite présenter une famille d’outils qui vont compléter les solutions SaaS et PRaaS : ce sont des logiciels qui permettent de ... construire des processus spécifiques sur le Cloud.
Quelles que soient la qualité et la variété des solutions SaaS/PRaaS disponibles, les entreprises auront toujours besoin d’un peu de flexibilité pour gérer des processus qui leur sont spécifiques.
Lotus Notes/Domino a été, pendant 15 années, l’excellent outil qui répondait à ces attentes.
Les offres modernes, pour le Cloud Computing, sont encore très jeunes, mais pleines de promesses.
J’en citerai deux, françaises, qui proposent des approches différentes, et très complémentaires, pour construire ces processus “sur mesure” : - RunMyProcess (RMP). RMP permet de développer des processus qui s’appuient sur les solutions SaaS existantes dans l’entreprise. A titre d’exemple, Revevol a utilisé RMP pour automatiser la prise de commandes de Google Apps. (Remarque : Revevol est partenaire de RunMyProcess).
- Vdoc Software, de la société Visiativ. Je les ai rencontrés récemment, et je trouve leur démarche intelligente. Leur outil permet de développer rapidement des processus spécialisés autonomes, qui pourront s’exécuter sur le Cloud. Je pense que ce sera un outil utilisé en priorité par des consultants ou sociétés ayant une forte compétence dans un métier spécifique.
Cet outil leur permettra de construire des ... PRaaS !
L’arrivée de PRaaS est une excellente nouvelle pour les entreprises utilisatrices de solutions informatiques.
Dans les cinq années qui viennent, l’offre de PRaaS couvrira, très bien, l’essentiel des processus de soutien dont ont besoin les entreprises.
Ceci leur permettra de concentrer toute l’énergie de leurs équipes informatiques sur les seuls processus métiers, porteurs de compétitivité et de différentiation.
PRaaS, on en reparlera dans le prochain chapitre de la saga Tsunami Cloud/SaaS consacrée aux éditeurs de logiciels !
