Projects

ESBMT - A Multi-Tenant Open-Source Enterprise Service Bus

In the scope of this project we investigate how to make a proven PaaS technology such as an Enterprise Service Bus (ESB) Cloud-aware. As multi-tenancy is one important aspect to ensure Cloud-awareness we extended an open source ESB for multi-tenant aware communication and multi-tenant aware administration and management.
