Data center migration B E S T P R A C T I C E J O U R N E Y S Migration journey Finland's national airline Finnair carried 14.7 million passengers in 2019 but just 3.5 million in 2020. © 2022, Amazon Web Services, Inc. or its affiliates. Finnair chose to migrate to the cloud and used the rare opportunity of COVID-19 to drive the migration forward in months rather than years. Finnair's project was complex involving approximately 400 servers and 70 applications which were vital to Finnair's daily operations. The estate was a mixture of Windows, SAP, VMware, legacy Windows 2008, Windows 2003 and even Windows 2000, Oracle, and IBM AIX software. Finnair achieved substantial cost savings by exiting two data centers and migrating 70 applications previously hosted on approximately 400 servers onto AWS. The airline now has a flexible, scalable system ready for post-pandemic travel. Save costs by migrating off-airport data center Off-airport DC migration Secondary DC migration Primary DC migration 8 Most airports have at least three main data centers; two on the airport campus and one off airport (usually in a shared datacenter location). The data centers can be expensive to maintain and often the physical location of the data centers doesn't give the geographical redundancy required for best practice operational resiliency. Moving the off-airport data center to the cloud has the benefit of saving costs, increasing resiliency, and it gives the airport IT staff the experience of cloud migration. Unlike prioritizing by workload type, prioritizing by location means that different workload types are migrated early in the airports migration journey. This gives the airport the ability to identify and resolve any migration issues specific to individual systems. While the next stage is the secondary data center, the airport should use this opportunity to audit all IT systems and migrate anything not already hosted in a data-center. The final stage is to migrate workloads from the primary data center. Some workloads and devices require low latency access to on-premises systems, local data processing, data residency, and local system interdependencies – for these situations we have a range of Edge services such as AWS Outposts, AWS IoT Greengrass, and AWS Panorama which allows airports to extend and run AWS services locally.
