6 Infrastructure resiliency and modernization For many airports the decision to move to the cloud is driven by a need to modernize and improve their IT infrastructure. On-premises systems and storage require regular hardware refreshes and often new hardware investment is necessary to cope with growth, new systems, and the increasing volumes of data. Airports face large capital investments compounded by the need to plan ahead, buy, and provision hardware that will meet the projected future peak demands. The cloud offers an attractive alternative where airports can pay only for what they consume and, with the benefit of cloud's massive scale, it costs less. Plus it saves the airport's scarce IT resources the time and effort of building and managing physical infrastructure. While most airports will have some experience with cloud computing from their technology and service providers, for some this is the first time they are migrating workloads to AWS. Airports generally start by auditing all their on-premises workloads and prioritize the sequence of migration, starting with least critical workloads. In some cases the priority is determined by the criticality of the existing infrastructure prioritizing phasing out old hardware (due to costly refresh or license renewals) and addressing security risks. B E S T P R A C T I C E J O U R N E Y S Migration journey In 2018, Bahrain Airport Company (BAC) wanted to modernize their IT infrastructure and began migrating its systems to the cloud, reducing its on-site hardware dependency. deployment. © 2022, Amazon Web Services, Inc. or its affiliates. The decision came on the back of high growth (7% annually) and the need to enhance IT system resilience and availability while accelerating the delivery of new IT services. BAC selected AWS and was one of the first companies in Bahrain to adopt the flexible and scalable approach of building their IT infrastructure in AWS. BAC migrated most of its web applications and re-architected its IT environment. They recently moved other services to AWS, including the Access Pass Management System, IT asset management system, Active Directory integration service, and network policy system.
