Experience before the interview
The Missing Piece Is Experience.
Certifications, college courses, and online videos can provide knowledge. Employers, however, frequently want candidates who can actually perform the work — configure the service, read the logs, find the failure, and restore operation.
“Every job wants experience. But how do you get experience if nobody gives you the opportunity?”
Mobile ITT Solutions is built to help bridge that gap through extensive hands-on labs, infrastructure builds, troubleshooting scenarios, and simulated enterprise environments. Mobile ITT Solutions is designed around doing — not simply watching.

Hands-on work
What Students Will Actually Do
Every skill below is practiced on systems students configure themselves — not described in a slide deck.
Build Linux servers
Install, configure, and maintain RHEL systems from bare install forward.
Administer Red Hat Enterprise Linux
Users, permissions, systemd, packages, storage, and performance.
Build a Windows Domain Controller
Roles, features, remote administration, and server hardening.
Configure Active Directory
Domains, OUs, users, groups, and group policy fundamentals.
Join Linux systems to Windows domains
SSSD, Kerberos, and cross-platform authentication.
Configure DNS and networking
Forward and reverse zones, DHCP, routing, and name resolution.
Build centralized logging
Forward system logs from many hosts into one log server.
Configure NFS and network storage
Exports, mounts, permissions, LVM, and capacity planning.
Deploy databases
PostgreSQL installation, roles, connectivity, and backups.
Configure web and application servers
Apache virtual hosts, TLS, and containerized services with Podman.
Automate administration with Ansible
Inventories, playbooks, roles, and repeatable configuration.
Write Bash, Powershell, and Python scripts
Automate routine administration on both platforms.
Configure backup and recovery
Backup schedules, restores, and recovery validation.
Harden Linux systems
SELinux, firewalld, auditing, OpenSCAP, and AIDE.
Troubleshoot broken services
Diagnose failures using logs, status, and systematic method.
Diagnose networking problems
Connectivity, DNS, routing, and firewall analysis.
Work through simulated support tickets
Realistic queues with priorities and documented resolutions.
Build multi-server enterprise environments
Linux and Windows systems operating together as one estate.
Flagship project
Build an Enterprise Environment From the Ground Up
Isolated exercises teach commands. Environments teach engineering. Students work toward building realistic multi-server infrastructure where services depend on each other — so a DNS mistake breaks authentication, and a full filesystem takes an application offline.
Linux and Windows operate together inside a single enterprise environment: Active Directory provides identity, RHEL hosts the applications and databases, logging and monitoring provide visibility, and Ansible keeps configuration consistent.

Troubleshooting
Engineers Aren't Paid Just to Build Systems. They're Paid to Fix Them.
Students intentionally encounter failed systems. Services stop. Authentication breaks. Storage fills. Configuration changes take an application down. The work is to diagnose the cause methodically, restore service, and document the resolution.
Tickets arrive with symptoms, not answers — the same way they do on the job.
