Use case

Seamless Migration from AWS ECS to EKS for Enhanced Scalability and Efficiency

About the Customer

CyvexTech provides an API that ensures secure financial transactions within applications. It monitors the entire transaction process from initiation to completion, preventing unauthorized access and detecting irregularities to maintain data confidentiality and security.

Customer Challenge

CyvexTech had been using Amazon ECS for its infrastructure but identified the need for a more flexible, cloud-agnostic solution to improve functionality and scalability. The primary motivation was to plan for potential future cloud migrations and on-premises Kubernetes deployments. Secondary challenges included ensuring dynamic environment isolation, resource optimization, and enhancing security and compliance.

The challenge was to migrate their existing infrastructure from ECS to EKS while maintaining continuous service availability, optimizing resource usage, and implementing robust security measures. Additionally, it was crucial to establish dynamic environment isolation within the same cluster and minimize downtime throughout the process.

Solution

IAMOPS provided a robust migration strategy, moving CyvexTech’s infrastructure from ECS to EKS. This transition enabled greater scalability, flexibility, and security for their platform.

Infrastructure as Code (IaC):

Using Terraform, IAMOPS deployed an AWS EKS cluster within a VPC, ensuring the infrastructure was consistent, traceable, and reproducible across environments. This included configuring networking resources with AWS ALB, Nginx-Ingress, CloudFront, and Route 53.

Microservices Deployment:

The migration of microservices such as Airflow Scheduler and Superset App was facilitated through Kubernetes and Helm charts. This ensured seamless integration of services from ECS to EKS, alongside the deployment of secrets management systems.

CI/CD Pipeline:

A CI/CD pipeline was developed using GitHub Actions for application build and deployment, and Argo CD for monitoring the deployment process. This enabled efficient automation of development workflows and application management.

Monitoring Stack:

IAMOPS implemented a comprehensive monitoring stack using Grafana, Prometheus, Loki, Mimir, and Uptime-Robot to ensure real-time observability of the infrastructure and applications. This allowed CyvexTech to monitor performance and respond to issues proactively.

Security and Compliance:

Security best practices were enforced through the use of AWS Secrets Manager, SSL/TLS encryption, and IAM policies. Data was encrypted at rest and in transit using AWS Key Management Service (KMS), and backups for RDS databases were automated for disaster recovery.

By following AWS best practices, IAMOPS ensured that CyvexTech’s migration to EKS was smooth, secure, and optimized for cost-efficiency.

Results & Benefits

The migration to AWS EKS provided CyvexTech with several key benefits:

Scalability and Flexibility: The ability to scale applications and manage increased workloads was significantly improved.
Cost Optimization: Resource consolidation and more efficient utilization of infrastructure resulted in reduced costs.
Enhanced Security: The built-in security features of EKS, combined with AWS-managed updates, ensured compliance and robust protection for sensitive data.
Operational Efficiency: CI/CD automation streamlined application management, and the comprehensive monitoring stack provided better observability for operational tasks.
