Enterprise architecture plays a crucial role in cloud migration, ensuring a holistic approach that considers all aspects of an organization's IT landscape.
The 6R methodology (Rehost, Replatform, Refactor, Retain, Retire, Repurchase) is a common framework used in cloud migration to categorize applications and decide on the best migration strategy.
Business capability mapping is a critical step in understanding the impact of migration on business functions and should be done at an appropriate level of detail to avoid getting bogged down.
The AWS migration framework includes tools and services like MGN (Application Migration Service) and modernization pathways to assist in the migration and modernization process.
Adidas's experience shows that enterprise architecture is heavily involved in the initial assessment phase of migration, helping to make fact-based decisions and identify necessary skills and budgets.
Petronas's cloud-first strategy highlights the importance of aligning digital initiatives with business goals, such as cost reduction and sustainability.
The human aspect of migration, including change management and employee engagement, is critical for success. Creating a culture that fosters innovation and aligns with technology shifts is essential.
Executive sponsorship is vital for successful cloud migration, as it helps in aligning the organization's leadership and teams towards common goals and outcomes.
