Introduction

The purpose of this document is to provide an overview of OneStream’s architecture and system requirements while giving guidance in choosing the proper deployment environment for a given user base. The anticipated audience is both those in Finance and Information Technology who make decisions on financial application deployment, desired functionality, security and support.

NOTE: While some concepts in this document apply to any OneStream deployment, this document focuses on customers who choose to implement OneStream on premise. For a list of the hardware and software components for each customer’s OneStream Cloud Service on Microsoft Azure, see the Cloud Architecture and Managed Services document.

OneStream supports a Rich Internet Application (RIA) that utilizes a Service-Oriented Architecture. It is architected in such a way to be highly scalable to support thousands of users. Engineered from the ground up as a native 64-bit application, OneStream allows you to take advantage of true 64-bit technology, including performance benefits, broader scalability, and a lower cost of ownership. At the heart of OneStream is a powerful in-memory, 64-bit financial analytic engine with sophisticated algorithms and caching technology that reduces database traffic and provides for an extremely flexible multi-dimensional model with enhanced calculation capabilities.
