IG1126 Introduction to the Digital Services Reference Architecture R14.5.1

The digital services reference architecture is intended to provide a standardized best practice for the enablement of open, interoperable virtualized digital services focusing on maximizing re-use, agility of operations and scalability to meet future demands. As more services are being developed using a mash-up of existing capabilities as well as products in the industry, a consistent framework for enabling end to end management of these services across the eco-system is required with particular attention paid to the integration of these capabilities to reduce customization tax while ensuring delivery of excellent end customer experience.

This reference architecture is designed to cater for multiple different business models, and leverages work in the Business Partnering Guide which rationalizes the many different types of business models to 3 key concepts, sell to, sell through and sell with.

A Digital Services Reference Architecture must deliver on three key value propositions:

• A High Quality User Experience Users are able to access the business application or see content in the manner they expect.
• A High Quality Developer Experience Developers are able to more quickly create applications in a consistent manner that can be easily incorporated into SOA Service Compositions that are readily manageable from a QoS and SLA viewpoint.
• A High Quality Operations Experience Service providers are able to provide a great user experience because they have the information necessary to measure what is going on, quickly assess root causes and impacts, and react to problems in a proactive manner.
