Reuse and Migration of legacy applications to Interoperable Cloud Services

Transcription

1 Reuse and Migration of legacy applications to Interoperable Cloud Services Migration et reutilisation d applications obsolètes sous formes de services interropérables dans le nuage

2 Pourquoi Remics? L informatique en nuage est une véritable tendance de fond. 75% du patrimoine logiciel mondial est en Cobol. Le savoir au sein des applications est dégradé ou perdu. Exécuter du Cobol avec un runtime dans le Cloud n est pas la solution recherché par le marché. Restaurer la logique métier, la préserver puis la faire évoluer à meilleur coût en Java ou.net passe par l automatisation (taille des patrimoines). 2

3 Qu est REMICS? Reuse and Migration of legacy applications to Interoperable Cloud Services Budget: 5,7 Millions 468 homme mois Durée: 09/ /2013 Cloud retenus: Amazon et Azure, cloud d infrastructure et hybride 3

4 Les grands objectifs 1. Découverte et extraction de la logique applicative. 2. Modélisation de service applicatif dans le nuage. 3. Patron de développement SOA pour le déploiement dans le Cloud. 4. Interopérabilité de service géré par les modèles. 5. Test basé sur les modèles pour les services applicatifs dans le nuage et mesure de la qualité par les modèles. 6. pour la gestion des applications en production. 7. REMICS: la méthodologie. 4
