Containers Blog
This article details how webMethods iPaaS transformed its legacy product into a multi-tenant SaaS platform using Amazon EKS, focusing on architectural evolution and key design strategies.
- Initially built on Kubernetes to leverage namespace-based tenant isolation and AWS's global infrastructure
- Used managed node groups to optimize resource allocation and reduce costs by approximately 10%
- Evolved architecture to multiple EKS clusters for better tenant isolation and reduced impact surface
- Implemented a hub and spoke networking model using AWS PrivateLink for secure inter-cluster communication
- Automated infrastructure provisioning using Terraform and CI/CD pipelines
- Enabled customers to integrate SaaS platform into their networks via transit VPCs
The incremental approach improved release velocity, reduced minor outages by 40%, and enhanced overall platform scalability and security.
