Case Study: Azienda Trasporti Milanesi achieves 24/7 data availability and uninterrupted public transport with Veeam

Veeam brings millions of Azienda Trasporti Milanesi users to their destination every day

Azienda Trasporti Milanesi (ATM) runs Milan’s complex public-transport network—metro, trams, buses, parking and bike sharing—serving millions of passengers every day. With a largely virtualized data center (about 600 VMs and 150 TB across primary and continuity sites) ATM needed uninterrupted data availability to support ticketing, payments, camera‑monitored restricted areas and third‑party integrations; any outage would harm service, revenue and city livability.

ATM deployed Veeam Availability Suite to protect its virtual environment, enabling fast, agentless backups and rapid recovery (for example, restoring an application cluster after a failed security update) to avoid days of downtime and financial loss. As a result, data‑based services remain always‑on, operational efficiency and payment verification are maintained, and cost savings are being reinvested in environmental sustainability projects like fleet electrification.
