The rapid shift towards cloud adoption within insurance, investment, and capital markets sectors has made AWS a go-to solution for many organizations. But moving to AWS involves more than just a simple “lift and shift.” Selecting the right migration strategy is critical to navigating unique industry challenges such as compliance, data integration, and cost management. This guide explores the key approaches for AWS migration, with a focus on rehosting, refactoring, and rearchitecting, and the important considerations for successful cloud transformation.
Key Challenges to AWS Migration
Migrating legacy systems to AWS requires a thoughtful business case, balancing cost-effectiveness, compliance, and technical feasibility. Below, we delve into the major hurdles organizations face during cloud migration.
Legacy Systems: Many financial institutions rely on legacy applications that are embedded into daily operations. While rehosting these systems on AWS can be relatively straightforward, it often fails to fully unlock the benefits of the cloud. Refactoring or rearchitecting these applications can offer greater scalability and performance, though they require higher upfront investments.
Cost Optimization: While AWS offers a pay-as-you-go model, it’s essential to understand future costs post-migration. Strategies like using AWS Reserved Instances and Savings Plans can reduce expenses, but careful financial planning is necessary to maximize long-term cost savings.
Regulatory Compliance: Strict regulations in financial services, such as GDPR, HIPAA, and the Dodd-Frank Act, demand constant vigilance. AWS provides robust compliance tools, including AWS Identity and Access Management (IAM) and AWS Config, to monitor and enforce compliance measures, ensuring that organizations stay within regulatory boundaries while safeguarding sensitive data.
Business Continuity and Disaster Recovery: Downtime during migration can be costly. AWS solutions like Elastic Disaster Recovery minimize disruptions and data loss in the event of a failure. Regularly testing disaster recovery plans is essential to maintain operational resilience.
Data Security: Financial institutions must prioritize data security, as cyber threats are ever-present. AWS offers several security features such as encryption, firewalls, and real-time monitoring to protect against data breaches.

Selecting the Right AWS Migration Approach
Organizations must choose the migration strategy that best aligns with their current infrastructure, goals, and resources. The three primary approaches are:
- Rehosting (Lift and Shift): Rehosting involves migrating applications to AWS with minimal changes. This approach is faster and less disruptive, ideal for organizations looking to move to the cloud quickly.
Challenges: While rehosting can deliver immediate cost savings, it doesn’t allow organizations to fully utilize cloud-native features like scalability, which could limit long-term benefits.
Best Use Cases: Ideal for businesses needing rapid disaster recovery or those reliant on legacy applications that can’t be easily refactored.
- Refactoring (Reshaping Applications): Refactoring modifies the application code to optimize it for cloud services. This approach unlocks AWS-native features like auto-scaling and serverless computing.
Challenges: Refactoring is resource-intensive and requires more time, but it results in significant performance and cost improvements in the long run.
Best Use Cases: Suitable for financial applications that require high scalability and performance, such as analytics platforms handling large volumes of data.
- Rearchitecting (Rebuilding from Scratch): Rearchitecting involves rebuilding applications to be cloud-native, maximizing the advantages of AWS technologies such as microservices and containerization.
Challenges: The cost and complexity of rearchitecting make it the most resource-heavy approach, best suited for organizations looking to modernize their applications comprehensively.
Best Use Cases: Ideal for companies seeking innovation through AI or machine learning capabilities, such as real-time fraud detection or predictive risk modeling.
Critical Considerations for AWS Migration in Financial Services
In addition to choosing the right migration approach, financial institutions must address unique concerns such as data quality, regulatory compliance, and integration with traditional financial data.
Data Quality: Reliable, high-quality data is vital for financial decision-making. AWS services like Amazon Glue streamline the cleansing and transformation of data, ensuring accuracy for analytics and AI models.
Data Integration: Financial institutions often rely on a combination of traditional and alternative data sources. AWS services like Amazon Redshift enable seamless integration, providing a unified platform for analysis and decision-making.
Compliance and Security: Financial organizations must stay compliant with an evolving regulatory landscape. AWS tools such as IAM and AWS Config help maintain compliance by controlling data access and continuously monitoring configurations against regulatory standards.
Key AWS Services for Financial Institutions
Some of the AWS services that add significant value to financial institutions include:
- Amazon S3: Scalable, secure storage ideal for storing large volumes of financial data.
- Amazon EC2: Provides scalable computing power for running financial simulations and AI models.
- AWS Lambda: Enables event-driven processes and serverless computing, perfect for automated reporting.
- Amazon RDS: A managed database solution for transactional data, simplifying database management with high availability.
- Amazon SageMaker: Facilitates building and deploying machine learning models at scale for predictive analytics and decision-making.
Conclusion: Crafting Your AWS Migration Strategy
Choosing the right AWS migration strategy is essential for insurance, investment, and capital markets sectors to remain competitive and future-ready. Whether through rehosting, refactoring, or rearchitecting, the approach must align with an organization’s specific needs, goals, and regulatory requirements. By addressing challenges like data security, regulatory compliance, and cost efficiency, organizations can leverage AWS to drive innovation and streamline operations in the financial landscape.
Cloud adoption is no longer just an option—it’s a necessity for financial institutions aiming to stay ahead in a fast-evolving market. AWS enables organizations to not only improve their operational efficiency but also transform the way they serve their customers.
