Repsense's Successful Migration from Azure to AWS: Enhancing Performance, Scalability, and Security
The Client
Repsense is a fast-growing AI-powered data company that analyzes a variety of media and predicts its impact on certain entities. To enhance performance, scalability, and security, Repsense decided to migrate its application infrastructure from Microsoft Azure to AWS. The goal was not just a lift-and-shift migration but a significant improvement in best practices, infrastructure management, and operational efficiency.

Cloudvisor transformed our cloud infrastructure, making our transition from Azure to AWS seamless and efficient. We’ve seen a significant boost in performance, faster deployments, and a more scalable setup that supports our growth. Their expertise allowed us to optimize operations without disruption, giving us the confidence to focus on what matters - building great products for our customers.
Challenges
Repsense encountered several limitations with its existing Microsoft Azure setup:
- Scalability Issues: Performance was impacted due to infrastructure constraints, limiting the company’s ability to scale efficiently.
- Manual Infrastructure Management: Excessive manual effort was required for operations and maintenance, increasing operational overhead.
- Security & Compliance Challenges: Existing measures needed strengthening to meet industry standards and ensure end-to-end security.
These challenges prompted the need for a more flexible, automated, and scalable cloud solution.
Solutions
As an AWS partner, Cloudvisor designed and implemented a secure, scalable, and fully automated cloud environment tailored to Repsense’s needs. The solutions provided included:
Multi-Environment Deployment
Dedicated AWS accounts were created for Development, Staging, and Production to enhance security and streamline operations.
Infrastructure as Code (IaC) Implementation
Terraform was used to establish version-controlled, repeatable deployments, ensuring automation and consistency.
Seamless Kubernetes Migration
The customer’s compute infrastructure, already hosted on Kubernetes, was seamlessly migrated from Azure Kubernetes Service (AKS) to Amazon EKS, ensuring minimal downtime and improved scalability.
Database Modernization
Repsense was using a NoSQL database but planned a gradual migration to SQL. Amazon Aurora Serverless was chosen for its ability to scale dynamically without storage or performance concerns. Minimum and maximum ACUs were set, with periodic reviews planned.
Automated CI/CD Pipeline
Unified and simplified the deployment process with GitHub Actions, replacing a complex multi-tool approach.
Security Enhancements
AWS GuardDuty, AWS CloudTrail, AWS Client VPN, and vulnerability scanning were deployed to strengthen data protection, ensuring compliance and end-to-end security.
Data security during migration
A Site-to-Site VPN was set up between Azure and AWS to securely migrate production data.
