The solution had to support a “point-of-sale” type transaction with tens of thousands of expected client connections. To support the bid a proto-type was built and deployed demonstrating scale and through-put exceeding requirements and validating the viability of the Windows Azure Cloud based solution. This role included: • Analysis of end-customer use-cases and non-functional requirements from RFP documents. • Design of the platform architecture and interactions to minimise costs while ensuring data integrity and high availability in case of datacentre failure. • Design of a data scheme and horizontal scaling strategy for high concurrency. • Liaison with Microsoft specialists to ensure the latest understanding of the Azure platform and incorporation of support for large scale testing. • With the bid team, implementation of a proto-type, demonstrating the viability (aka. low latency) of a Windows Azure based service using IaaS, PaaS and SQL Database technologies. • Cost modelling for development, operational support and cloud services consumption. This demonstrated significant savings over a hosted solution.
