Low-Code App Hosting on AWS for Internal Workflow Automation
Customer Overview
C# Corner is a global community platform and software company that also builds and maintains internal tools for content workflows, event registration, partner outreach, and publication approval processes.
With a lean devops team, they adopted low-code platforms like Retool and Mendix to accelerate application delivery. However, their legacy hosting on VPS infrastructure created challenges around scaling, security, and availability. Their goal was to host internal low-code apps in a compliant, automated, and secure cloud environment.
Customer Challenge
- Limited scalability and resource constraints in current VPS hosting
- No fine-grained IAM or security isolation for app components
- Manual deployment and patching processes
- Lack of high availability or automated failover
- Cost inefficiencies due to over-provisioned static resources
- Risk of downtime affecting internal operations during events
Partner Solution
Revolutions.ai designed and deployed a container-based, auto-scalable AWS architecture for low-code app hosting. The solution used Amazon ECS Fargate with Application Load Balancer to host containerized apps built using Retool.
Each app was deployed in its own isolated namespace within ECS with automated CI/CD pipelines using AWS CodePipeline and GitHub integrations. Security was managed via IAM roles and Secrets Manager. All traffic was routed securely via HTTPS with Route 53 and ACM.
Infrastructure as code was used throughout to enable repeatable deployments. The deployment was aligned with the Well-Architected Framework for Operational Excellence, Reliability, and Security pillars.
AWS Architecture
Architecture Highlights:
- ECS Fargate cluster in private subnets
- Application Load Balancer with Route 53 DNS
- RDS Postgres for stateful storage
- S3 for static assets and audit logs
- IAM + Secrets Manager for secure credentials
- CodePipeline + GitHub + CodeBuild for deployments
