Transforming Enterprises with AWS: Lessons Learned and Proven Strategies
Executive Sponsorship and Business Case
Establishing executive sponsorship and buy-in is crucial for a successful migration and modernization journey
Defining a clear "North Star" or business objective, such as improving delivery speed, is essential for building a compelling business case
Leveraging benchmark insights from other customers who have executed large-scale migrations can help build the business case
Empowered, Single-threaded Leadership
Appointing a single-threaded leader who can remove blockers and bring together all necessary stakeholders is a key lesson learned
This leader ensures the required resources are available and helps navigate organizational changes during the transformation
Cloud Centers of Excellence (CCoE)
CCoEs can be a powerful means of driving change, but they need to be set up and managed carefully to avoid becoming a bottleneck
Centralized CCoE functions like enablement, security, and compliance standards are important, but federated CCoE teams can also provide value by working closely with individual business lines
Migration Readiness Assessment
Conducting a thorough migration readiness assessment, either with AWS ProServe or an APN partner, can help identify focus areas and ensure a successful migration
Leverage AWS Tools and Services
Avoid building custom landing zones or infrastructure as code; use AWS Control Tower to establish the foundational layer
Utilize AWS tools like Application Migration Service (MGN), Database Migration Service (DMS), and DataSync to accelerate the migration process
Consider leveraging AWS-provided observability and monitoring solutions to support the migration and modernization journey
Transformation Experience
Embrace a "build, support, iterate" mindset for application teams, where they own the cost and observability of their workloads
Implement principles like "if you build it, you support it" to drive operational ownership and accountability
Leverage automation and AI/ML-powered tools to streamline and accelerate the migration and modernization processes
Danske Bank's Transformation Journey
Danske Bank has achieved remarkable migration velocity by automating the entire process and reducing the manual effort required

By embracing a principle-driven approach, leveraging AWS resources and expertise, and driving organizational transformation, enterprises can achieve remarkable results in their cloud journeys
