Sky - Interactive TV Chat Project

British Sky Broadcasting operates Sky Digital the most popular subscription television service in the UK.

Project Requirements
To deliver a "no-single-point-of-failure" hosted architecture for an Interactive TV chat application to be deployed using the Sky Interactive Micro browser, using an existing hosting company and making as much use as possible of hardware purchased for a previously cancelled project. The project had to be completed within a very short timescale in order to meet the customer's business needs.

The Solution
Layer3 worked closely with Globix to design and deliver a multi-tiered environment: the firewalls and other networking being designed in conjunction with Globix and the server architecture being designed and installed by Layer3 staff.

The server-level solution consisted of 10 Windows 2000 web servers connected to a Windows 2000 Advanced Server database cluster using SQLServer 2000 with a Fiber Channel Storage Area Network, while the infrastructure solution comprised 3 pairs of CheckPoint Firewall1 on RedHat Linux with RainWall clustering

Benefits
• £250,000 license savings.
• £150,000 hardware reuse savings.
• Allowed Sky to deploy the first ever Interactive TV chat service successfully to budget and within the specified timescale.
• Maximum re-use of existing servers
• Architecture designed for a lifespan beyond this one project, allowing additional service deployments without further large infrastructure investments.
