ResNet
Infrastructure for the SaaS company
About the Customer
ResNet, a provider of SaaS solutions, required a robust, high-availability infrastructure to manage resources and ensure seamless scalability dynamically. The company turned to Triangu to design and implement an optimized AWS-based solution to meet these needs.
The Challenge
Key challenges included:
- Implementing high availability with Kubernetes to ensure 24/7 operations with zero downtime.
- Dynamically managing resources to optimize cost and performance.
- Re-architecting the infrastructure to follow an IaC-driven deployment model for consistency and scalability.
They aimed to leverage Amazon EKS (Elastic Kubernetes Service) to run containerized workloads efficiently while adopting an Infrastructure as Code (IaC) approach to re-architect the entire system.
Goals and Delivery Description
The primary objectives of the project were:
- Seamless and automated infrastructure management using Infrastructure as Code (IaC).
- Dynamic workload scaling with EKS, ensuring optimal resource allocation.
- High availability and resilience, minimizing downtime and improving service reliability.
- Enhanced security and compliance with AWS-native security tools.
Triangu deployed the solution in an iterative, CI/CD-driven manner, making small but impactful changes to ensure a smooth transition. The IaC-based deployment model ensured that infrastructure changes were automated, version-controlled, and reproducible, eliminating manual interventions.
The team leveraged Werf, GitHub, Atlas MongoDB, and various AWS services to manage and deploy applications efficiently. Our architects built the solution around Amazon EKS, complemented by Amazon EC2 for compute resources and several AWS-native security, networking, and observability tools.
The deployment process followed a structured workflow:
Pre-Deployment:
- All code changes were committed and reviewed.
- Configuration files were updated with the latest environment variables and secrets.
Testing & Validation:
- A dedicated EKS cluster was provisioned for testing.
- Deployments were managed via ArgoCD to ensure configuration consistency.
- Automated tests (unit, integration, and end-to-end) were run in the CI/CD pipeline.
Approval & Deployment:
- Test results were reviewed, and sign-off was obtained.
- The solution was deployed to production EKS clusters using ArgoCD.
Post-Deployment & Monitoring:
- Smoke tests verified system functionality.
- Application logs and metrics were monitored using AWS CloudWatch.
- Post-deployment review meetings ensured continuous improvement.
The Solution
The implemented solution leveraged a suite of AWS services to ensure scalability, security, and performance:
Compute & Orchestration
- Amazon EKS – Kubernetes as a Service to run containerized workloads.
- Amazon EC2 – Elastic compute instances to support dynamic workloads.
Security & Compliance
- AWS IAM – Role-based access control for managing permissions.
- AWS Secrets Manager – Securely storing sensitive credentials.
- AWS GuardDuty – Threat detection and security monitoring.
Networking & Content Delivery
- Amazon VPC – Isolated network environment for secure resource access.
- Amazon Route 53 – Domain name resolution and traffic routing.
- AWS CloudFront – CDN for content delivery and performance optimization.
Messaging & Event-Driven Architecture
- Amazon SQS (Simple Queue Service) – Message queuing for decoupled microservices.
- Amazon SNS (Simple Notification Service) – Event-driven notifications and alerts.
- Amazon SES (Simple Email Service) – Email notifications for system events.
Storage & Container Registry
- Amazon S3 – Scalable object storage for application data.
- Amazon ECR (Elastic Container Registry) – Secure storage and deployment of Docker images.
Monitoring & Observability
- AWS CloudWatch – Real-time monitoring and alerting.
- AWS Chatbot – Integration with Slack for real-time deployment updates.
The Result
The AWS-based solution provided ResNet with a highly available, resilient, and scalable infrastructure, meeting their business objectives and technical requirements.
Key Outcomes:
- 24/7 Availability – Continuous operation without downtime.
- Automated Scaling – Dynamic resource allocation based on demand.
- Security & Compliance – Enhanced data protection with AWS-native security services.
- Efficient CI/CD Workflow – Streamlined deployment process via ArgoCD and GitHub.
- Cost Optimization – Improved resource efficiency, reducing unnecessary overhead.
By leveraging AWS-native services and best practices, Triangu successfully transformed Resnet’s infrastructure into a modern, Kubernetes-powered, cloud-native environment. This approach ensures sustained scalability, flexibility, and operational efficiency for ResNet’s SaaS platform.
