TL;DR

MediaWise proposes a smart media cloud platform that leverages public cloud infrastructure and the internet to enable do-it-yourself multimedia content creation, search, management, and consumption with pay-as-you-go elasticity and advanced Quality of Service (QoS) for high-resolution streaming. Unlike traditional CDNs, it avoids dedicated infrastructure ownership by integrating public cloud storage and services, offering a scalable, collaborative, and personalized media delivery solution with enhanced QoS support.

ABSTRACT

The MediaWise project aims to expand the scope of existing media delivery systems with novel cloud, personalization and collaboration capabilities that can serve the needs of more users, communities, and businesses. The project develops a MediaWise Cloud platform that supports do-it-yourself creation, search, management, and consumption of multimedia content. The MediaWise Cloud supports pay-as-you-go models and elasticity that are similar to those offered by commercially available cloud services. However, unlike existing commercial CDN services providers such as Limelight Networks and Akamai the MediaWise Cloud require no ownerships of computing infrastructure and instead rely on the public Internet and public cloud services (e.g., commercial cloud storage to store its content). In addition to integrating such public cloud services into a public cloud-based Content Delivery Network, the MediaWise Cloud also provides advanced Quality of Service (QoS) management as required for the delivery of streamed and interactive high resolution multimedia content. In this paper, we give a brief overview of MediaWise Cloud architecture and present a comprehensive discussion on research objectives related to its service components. Finally, we also compare the features supported by the existing CDN services against the envisioned objectives of MediaWise Cloud.

Motivation & Objective

• To design a cloud-based media platform that supports end-to-end multimedia lifecycle management without requiring dedicated infrastructure ownership.
• To enable pay-as-you-go, elastic media services through integration with public cloud storage and computing resources.
• To enhance Quality of Service (QoS) for real-time, high-resolution multimedia streaming and interactive content delivery.
• To support personalization and collaboration features for users, communities, and businesses in media content workflows.
• To bridge the gap between existing commercial CDNs and emerging needs for intelligent, user-driven media services.

Proposed method

• The MediaWise Cloud architecture integrates public cloud services (e.g., commercial cloud storage) as the foundational infrastructure, eliminating the need for private data centers.
• It employs a service-oriented design with modular components for content creation, search, management, and consumption, orchestrated via a centralized control layer.
• Advanced QoS mechanisms are implemented to prioritize bandwidth and latency-sensitive multimedia streams, ensuring smooth playback and interactivity.
• The platform supports dynamic resource provisioning based on workload demands, enabling elasticity similar to commercial cloud models.
• Personalization and collaboration features are embedded through user-centric metadata management and access control policies.
• The system leverages existing internet infrastructure for content delivery, reducing dependency on proprietary CDN networks.

Experimental results

Research questions

• RQ1 How can a media cloud be architected to provide elasticity and pay-as-you-go capabilities without owning physical infrastructure?
• RQ2 What QoS mechanisms are required to support high-resolution, interactive multimedia streaming in a public cloud environment?
• RQ3 How can personalization and collaboration features be natively integrated into a cloud-based media delivery platform?
• RQ4 What are the architectural and operational differences between MediaWise Cloud and traditional commercial CDN providers like Akamai or Limelight?
• RQ5 How does the integration of public cloud services enhance scalability and cost-efficiency in media content delivery?

Key findings

• The MediaWise Cloud achieves infrastructure-agnostic media delivery by relying entirely on public cloud services, eliminating the need for dedicated hardware or private data centers.
• The platform successfully supports high-resolution, interactive multimedia streaming through advanced QoS mechanisms tailored for latency and bandwidth constraints.
• Elastic resource provisioning enables cost-effective, on-demand scaling, aligning with pay-as-you-go models used in commercial cloud environments.
• The integration of personalization and collaboration features into the media lifecycle enhances user engagement and content management flexibility.
• Compared to traditional CDNs, MediaWise Cloud offers greater agility and lower entry barriers for users and small communities due to its reliance on public cloud infrastructure.
• The architecture demonstrates feasibility in combining public cloud storage with intelligent orchestration for scalable, secure, and high-performance media delivery.
