Payments Solution Architect Global Retailer

The client, a major UK retailer with significant overseas operations, was part way through a major programme of PCI Compliance and Architectural Change which had unmovable and fast approaching deadlines.  A turnaround plan was required in order to meet the deadlines. The consultant proposed the following plan of action:

• Separate the programme of work into three streams - Compliance, Microsoft Support Upgrades (Windows Operating System and .Net) and Architectural improvements
• Identify the parts of the programme of work that could not be moved (Compliance and Microsoft Support Upgrades)
• Identify the parts of the programme which could be implemented after the deadline (Architectural Improvements)

Following acceptance of the plan, a programme of the following work was successfully overseen:

• A complex rollout of Operating System upgrades to 30 production servers
• Testing of server upgrades and application installations
• Architecture of 14 new applications for two new Payment Service Providers to replace legacy applications
• Architecture of major upgrades to 30 existing Payments applications with replacement of core functionality
• Architecture of .Net Core version upgrades to around 30 applications

The following outcomes were achieved:

• 30 production servers were upgraded to Windows 2019
• 70 UAT servers were upgraded to Windows 2019
• 30 applications were re-architected and upgraded to .Net Core 6
• 14 new applications were implemented
• All goals for PCI Compliance were achieved
• All requirements for continuing Microsoft Support were achieved.
