Migrating Snowflake from AWS to Azure with Replication and Failover – Systech’s Successful Execution 

Introduction  

Cloud migrations are critical to staying competitive in today’s fast-evolving business landscape. For organizations leveraging powerful platforms like Snowflake, the migration process requires precision, planning, and expertise. Systech successfully managed the migration of a key client’s Snowflake environment from AWS to Azure, leveraging replication and failover strategies to ensure business continuity, security, and scalability throughout the process.  

Business Need  

The organization sought to migrate its Snowflake environment from AWS to Azure to meet the following key objectives:  

• Cost Management: Azure provided a more favourable pricing model aligned with the organization’s specific workloads, enabling efficient cost management. 
• Enhanced Performance: Azure’s infrastructure offered capabilities better suited to the organization’s performance requirements and long-term scalability.  
• Strategic Alignment: Migrating to Azure aligned the organization’s cloud environment with its existing investments and partnerships in the Microsoft ecosystem.  
• Compliance and Governance:  Azure’s advanced security features and compliance certifications addressed the industry’s stringent governance requirements.  

Systech’s Delivery Systech executed a seamless migration of the client’s Snowflake environment from AWS to Azure, focusing on replication and failover to minimize disruption and ensure data integrity. By following a structured approach, the migration was completed with no downtime, maintaining business continuity throughout the process.  

Overview  

To meet the business need, Systech deployed a robust solution that leveraged Snowflake’s replication, and failover features to seamlessly migrate data and workloads from AWS to Azure. This migration was crucial for ensuring the organization could continue its operations without experiencing downtime or data inconsistency.  

Systech’s approach to migrating Snowflake from AWS to Azure was divided into the following phases:  

1.Preparation and Planning  

• Ensured active Snowflake accounts on both AWS and Azure.  
• Verified permissions and set up replication groups for critical databases and schemas.  

2. Replication Configuration  

• Configured secure communication between the AWS and Azure Snowflake instances.  
• Established a robust replication setup to transfer all required data and metadata.  

3. Data Replication and Synchronization  

• Monitored the replication process to ensure data consistency and security.  
• Implemented a data freeze on AWS to prevent changes during the final synchronization.  

4. Failover and Cutover  

• Executed the failover process, making Azure the primary Snowflake instance.  
• Validated the migration’s success, redirecting all applications and services to Azure.  

5. Post-Migration Support  

• Provided ongoing support to ensure optimal performance and seamless integration of the Azure Snowflake instance.  
• Decommissioned the AWS instance after verifying the migration’s success.  

Impact  

The migration from AWS to Azure with Snowflake replication and failover had a significant positive impact on the organization’s business operations:  

• Business Continuity: The migration, executed with minimal downtime and seamless failover, ensured uninterrupted business operations throughout the transition.  
• Cost Efficiency: Post-migration, the organization benefited from Azure’s more cost-effective pricing for their specific workloads, significantly reducing overall cloud infrastructure costs.  
• Improved Performance: The migration resulted in improved data query performance, as Azure’s optimized infrastructure aligned better with the organization’s specific needs.  
• Enhanced Data Security and Compliance: With Azure’s enhanced security features and compliance certifications, the organization was able to maintain a higher level of data security, ensuring their data governance requirements were fully met.
