Customer success story: Finnair
“People didn’t think the move could
be executed in such a short
timeframe, especially given
constraints around coronavirus.”
Tiina Flytström
Head of Infrastructure and
Cybersecurity, Finnair
Key project milestones
• Solution: MAP MRA, CloudEndure & Migration Factory, Cloudamize,
AWS RDS, AWS SAP HANNA
• Delivery team: Proserv, NordCloud Lead Partner
• Migration scope: 400 servers, 70 applications which were vital to
Finnair’s daily operations. Mixture of Windows, SAP, VMware, legacy
Windows 2008, Windows 2003, Windows 2000, Oracle, and AIX
• Timeline: Engaged in September. Completed migration in November
(45-day project)
• Key activities: Immersion day, partner training, wave planning, rapid
inventory validation
Migrating with

Finland’s national airline, Finnair, carried
14.7 million passengers in 2019 but just
3.5 million in 2020. A move to AWS
helped it cope with this turmoil while
controlling costs. The migration provides
an agile and future-ready infrastructure to
power Finnair’s digital transformation and
future growth.

Why AWS modernization?
Developers wait
days/weeks for
infrastructure
to be provisioned
Tooling is
inconsistent
across teams
Software is manually
deployed on an
ad-hoc basis
Security is
configured ad-hoc for
each application
Developers lack
visibility into
applications running in
production
Drivers Solution
Developers provision
infrastructure on
demand and deploy
in minutes
Software delivery is
automated via continuous
delivery pipelines
Applications are fully
instrumented for metric
and log collection
Organizations
standardize on tools
and best practices
Security best practices
are baked into every
application and service
