    ÉCOLE DES MINES
    2016 - 2019

    Specialization: System and network infrastructures
    Fields of study : Infrastructure, Cloud computing, Virtualization, TCP networking
    Certifications : CCNA (Cisco), CSNA (Stormshield), TOEIC 950

    Final study project : Information system infrastructure
    In order to optimize their IT resources and storage capacity, the engineering school needed a solid, scalable, VM driven
    information system for their IT teachers and students. Our class set up a VMWare powered infrastructure, in which I
    participated as a backup on many system and networks topics, such as network services (DNS, LDAP, VPN...), cloud
    computing orchestrators(VMWare, Kubernetes) and led the "VM on demand" part of this project :
    Requirements :
    • A strict role system, in order to allow teachers to manage their resources and those of their students
    • Set up a virtual machine or a service container with a template or custom configurations
    • Set up a provisioning system for automated node configurations
    • Implement a solid security system for VM access
    Technologies and features :
    • A PXE system daemon implemented with Python, connected to a Redis message queue
    • A network-managed boot-up system, secured with SSH-key based access
    • A PostgreSQL database, containing LDAP information and security access controls
    • A web interface, allowing users to complete forms for service and configuration data
    • A visualization of services and VM information and status
    Results :
    • A user-friendly web-application
    • Users can deploy a new custom virtual machine within 2 minutes
    • A scalable and evolving stack of services

    Other projects and collaborations
