Infrastructure

Parce qu’elle est vitale dans les projets Big Data, nous vous aidons à développer et à mettre en œuvre l’infrastructure de données appropriée et compatible avec votre environnement informatique existant.

Nos compétences couvrent les étapes clés du design et de l’architecture tels que le réseau, la surveillance, le diagnostic et le reporting, en passant par le déploiement automatisé, la configuration et la sécurisation. Notre expertise s’étend sur une multitude de technologies et de distributions Big Data.

Nous avons à de multiples reprises sécurisé avec Kerberos les distributions d’Hortonworks, de Cloudera et de MapR et avons l’expérience de mener des ateliers réunissant plusieurs acteurs de votre organisation en vue d’intégrer les plateformes Big Data avec des technologies comme SSL, l’Active Directory, FreeIPA, MIT Kerberos et OpenLDAP.
