Belitsoft migrated to Azure the IT infrastructure (around one of their core business applications including this application itself) of the global creative technology company Technicolor (17,000 employees) to provide steady web access to its staff employees in the USA, the UK, Canada, Australia, and other countries.
Initially, the IT infrastructure of Technicolor consisted of a single physical server initially meant for European employees only.
Over the years, Technicolor evolved from a local European company to an international enterprise. The company had been growing and opening offices in different locations, including Asia.
Accordingly, the current requirements of the global enterprise grew beyond the legacy IT infrastructure, which resulted in slowing business operations performance.
The core web app loading became very slow. Periodically, this core business application didn't work at all.
Additionally, the speed also slowed down owing to the VPN usage. Waiving of the VPN, however, contradicted the client's security requirements.
At the end of the day, the employees struggled to access the key web application that they used daily to perform working tasks.
Waiting just for the app loading might result in 500 hours of downtime per month.
