Technology stack

The following sections provide a quick reference to the technologies that power Grand Central iPaaS. For detailed architectural information, see Platform architecture.

Core infrastructure

Grand Central iPaaS runs on Microsoft Azure with Kubernetes-based container orchestration.

Component	Technology	Description
Cloud provider	Microsoft Azure	Enterprise cloud platform with financial services compliance
Container orchestration	Azure Kubernetes Service (AKS)	Managed Kubernetes for workload deployment and scaling
Container registry	Azure Container Registry (ACR)	Private storage for Docker images and Helm charts
Package management	Helm	Kubernetes resource packaging and versioned deployments

Integration and runtime

The integration runtime combines Apache Camel with Kubernetes-native execution.

Component	Technology	Version	Description
Integration framework	Camel K	v2.6.0	Serverless integration logic on Kubernetes
Serverless runtime	Knative	v1.18.1	Auto-scaling and event-driven workload execution
