This government agency has a large complex core system with several hundred front-line employees accessing it across the country. It is critical that this core business system is available 24 hours a day, 7 days a week.
The government agency’s existing core business system is built on 1990s infrastructure using proprietary software and technology, making it difficult and costly to support and innovate. To provide a modern platform for ongoing support, maintenance and upgrade of the application they are now making the move to a containerised cloud solution which provides them with an open platform and greatly increases their future technical options and ability to innovate.
The agency needed a sophisticated cost model to understand how different component and deployment architecture combinations impacted their total cost of ownership to host, upgrade, and maintain the solution over the next 10 years.
Working closely with the project managers, architects, steering committee, vendors, and the client finance team, our Principal Consultant developed architectural models for the solution options and identified the key decisions that would drive procurement and operational costs.
Component dependencies were also analysed to ensure the sequencing of the solution build and timing of component procurement occurred in a logical and cost-effective sequence and aligned with budget timeframes.
The cost model was updated and refined continuously as new information became available following the analysis and testing of components. Sparx EA was used to build a visual representation of the core system options to inform the cost modelling and to allow for the ongoing refinements.
