Non-TCO Drivers Are Over 90% of Business Value
IDC found that AWS customers were able to
achieve much more than costs savings.
They explained that AWS has enabled their customers
to provide IT services more cost effectively, and
changed the role IT plays in supporting the
businesses.
Study participants moved IT from being a static entity
with real resource and performance constraints to an
enabler of business value.
Chief Architect is keen to start migration and
modernization of E-KYC application
