Cloud Migration & IT Renewal for a Global Financial Services Provider

A global financial services organisation faced a mandatory datacentre exit due to provider shutdown. With legacy systems, high operational risk, and 24×7 service requirements, the organisation needed a rapid yet controlled migration to a modern cloud platform.
