Chapter 2: Introduction What is Medulla? Medulla is a comprehensive IT management platform designed to simplify, automate and secure all the operations related to a computer park, whether in business, telework or distributed on several sites.   It is based on a real-time XMPP inventory base, allowing an accurate and up-to-date view of each station at any time, whether connected locally or remotely. This ensures constant machine connection, essential to any efficient management. What's Medulla for? Medulla centralizes and facilitates the following tasks: IT management Automatic and real-time inventory Detailed view of machines and users Connecting to existing ITSM solutions Remote deployment of software and scripts Deployment of applications, uninstallation or script execution Advanced planning via a Conditional staple Intelligent assistant for silent installations Imagining and System Installation Creating generic system images, compatible with all types of hardware Dynamic driver management Deployment Unicast/multicast Multi-site synchronization for remote deployments Application management and updates Application kiosk for users without admin rights Installation on request, by category Transparent and bandwidth-efficient updates Remote control ( LDCD ) Opening of session or console on posts Secure connection even without VPN thanks to an SSH tunnel Real-time support, everywhere Native telework support Secure access to remote stations No VPN addiction Performing all remote operations To discover all the features and deepen your knowledge, download our additional documentation by clicking here.

Cluster Server group that works together to distribute load, high availability and resilience. Imagine Here we talk about a system image or snapshot (disk image) of a workstation or server containing OS and software. It's used for quick deployments or restorations. Logs It's also called Journalization, it's a mechanism that records system events, errors, access, user actions. Very useful for audits and security. OR Organizational unit is a hierarchical structure in a directory (e.g. LDAP) that is used to organize machines and users. Package It is a set of files and resources that contain an app ready to be installed and configured on a computer or server. Packages are in deposits and are managed by package managers. P.M.A.D. Remote control Relay The relay is a component that allows messages to be passed between different points of the network. Rules A rule is a set of criteria to determine which relays or server should be used. XMPP XMPP means Extensible Messaging and Presence Protocol and is used for instant messaging, presence and real-time communication. Conditional Grafcet Planning method based on GRAFCET (Prophet Functional Control Step/Transition), used to automate action sequences (such as software deployment or script execution) according to specific conditions. Each step only executes if defined conditions are met, allowing dynamic and intelligent process management. Unicast Network communication mode where only one source sends data to a single destination. Used for point-to-point transmissions. Multicast Network communication mode where only one source sends data simultaneously to several specific destinations, without sending separate copies to each receiver. VPN (Virtual Private Network) Virtual private network to create a secure and encrypted connection between a user and a network, often via the Internet. It protects the data, hides the IP address and guarantees confidentiality. SSH (Security Shell) Secure communication protocol to establish a remote encrypted and authenticated connection to access a system and execute commands. Used mainly for server administration and secure file transfer. Wake-on-LAN, WOL network alarm Functionality allowing to start a remote computer via a network, sending a special package called Magic Packet containing the MAC address of the target machine. Used for remote administration and machine management without having to turn them on manually.
