Paper Presents a Cost Evaluation Tool and Examines the Architecture Components Required to Deliver Multi-Tenant, Shared Application Platform Services Palo Alto, CA – June 18, 2012 – More and more enterprise IT teams are considering how to deploy middleware as a service instead of running multiple, traditional middleware platform silos. Clearly there are cost advantages to running middleware in the cloud, for example an ESB-as-a-service, rather than maintaining on-premise servers and storage. However, not all platform-as-a-service (PaaS) models yield the same total cost of ownership (TCO). To help IT professionals evaluate their TCO, WSO2 has published a new white paper. The paper, “Cloud Native Advantage: Multi-Tenant, Shared Container PaaS,” describes the architecture components required to deliver multi-tenant, shared application platform services. It also proposes a cost evaluation tool that compares the deployment footprint associated with a multi-tenant, shared application container PaaS versus a single-tenant, dedicated container PaaS (i.e. traditional application server deployment in cloud). The analysis reviews multiple tenant count and application platform service scenarios. An associated TCO worksheet incorporates the application platform license (or subscription) cost, PaaS management service cost, infrastructure expense, and IT management overhead. Additionally, the paper examines how multi-tenant application platform service instances can host multiple tenants with appropriate resource isolation and deliver a significant cost advantage. It also explores how cloud-native containers are purpose-built to overcome context isolation challenges, deployment tooling issues, and resource sharing impediments. Finally, it explores how cloud application architecture components (e.g. a cloud-aware code deployer, tenant-aware administration screens, and tenant-aware load balancing) create a safe, multi-tenant environment while maximizing resource sharing and lowering cost.
