Architect Lead Consultant 

Siemens IT Solutions and Services offer an extensive supply of IT services and solutions for business customers and large-scale enterprises.

Account: National Savings and Investments (NS&I)

Sector: Government

Programme: NS&I Infrastructure Refresh Programme

The NS&I strategy is part of a requirement valued at £70 (seventy million) GBP for Siemens to completely refresh all aspects of the NS&I infrastructure across its four key locations and condense the estate's data and network services to two hosted datacentres.

My role as Architect Lead Consultant was to have responsibility for working with the sales team and Solution Architect defining both the high level and detailed solutions (e.g. design and build of the two datacentres). The delivery lifecycle was from solution proposal stage through to implementation and handover of the agreed solutions. I was also to ensure that all related budgets/timescales were realistic, as well as manage the implementation teams (5 engineers) in delivering a high performance solution. I assisted in creating a COM (Current Operating Model) and TOM (Target Operating Model). This approach allowed Siemens to demonstrate the competitive advantage of the solution, and we were subsequently nominated for the Project Team of the Year Award.

Due to the scale of the programme several solution streams were created. I managed the direction of the solutions through to delivery to ensure the project stayed in line with the strategic aims and Siemens standards. I was responsible for and gave solution direction/assurance on the following areas:

• Datacentre and Hosting Strategy
  Deliver a strategic approach for the primary Datacentre and secondary Datacentre and ensure all solutions were flexible to adapt to any requirements. This included specifying data centre environmental specifics (floor space, cooling, power etc) as well as the design and build out of the Core Network Infrastructure (MPLS, core/backbone routing and switching, loadbalancing and firewalls/security) to support other work streams.
  
• Transformed Network Environment
  I designed and managed the conversion of a 4 site Bridged LAN/WAN topology to a fully Routed LAN/WAN topology. I also designed and managed the MPLS migration from an ATM based WAN; establish trusted/untrusted DMZs, and secure remote access to Development Teams in Brussels, as well as designing and transforming NS&I's ageing Firewall Policy.
  
• Wintel Server consolidation/transformation
  VM 3.5 farm implemented to virtualise key Wintel services and scale for future growth, transform from NT4 to Windows AD. My role was to design and manage the implementation of the HP Blade Enclosure switching to ensure optimum performance back to the core backbone network.
  
• Ecommerce
  Redesigned the E-Commerce network infrastructure for NS&I’s front end website.
• Application migration/consolidation
  Assist in managing the application packaging/migration effort along with flagging any problematic legacy applications. This in turn meant affecting a strategic approach for upgrading, consolidating, rewriting or retiring legacy applications.
• Expansion of the UNIX environment
  Assist with the increase of IBM P570 capacity and prepare for virtualisation/migration of disparate services.
• Desktop consolidation/transformation
  Assist with the design of the thin/rich client rollouts, New Citrix infrastructure, App-V infrastructure, and UniPrint infrastructure.
• Transition and Service wrap
  Ensured all transition criteria into BAU and service levels were within Siemens standards.
  

In addition to all of the above I communicate overall progress with key stakeholders (LoS, HoS and Board Members) on a regular basis. This provided ongoing assurance and ensured the customer recognised they have a trusted partner with Siemens. Maintaining the ongoing relationship is vital for the success of the project as it allows for a degree of transparency from Siemens whilst simultaneously establishing a high level of confidence with Siemens.
