MD1350 Transition of IT Services to TfL Datacentre

A key priority for the Technology Group (TG) - as articulated in the GLA Business Plan 2014/15 to 2015/16 - is to "Implement measures to strengthen business continuity of services at City Hall " (p86) [1]. The GLA plans to achieve this by implementing a multi-phase programme to build a private cloud infrastructure in partnership with TfL using two offsite datacentres as outlined in the Information Technology Programme 2014/15 and the TG Business Continuity Strategy (Appendix 01).

Phase 1 of this programme is a discrete collection of related works totalling £230,000 capital expenditure from a number of suppliers and following a number of discrete procurement exercises. This total includes the previously approved ‘DD1152 Server Upgrade’ and ‘DD1155 Additional IT Data Replication Appliance’. Approval is now sought for an additional purchase of network switch and network storage equipment not exceeding £75,000 from the existing 2014/15 Technology Group capital budget and £3,300 revenue expenditure to be contained within the existing TG revenue budget. As the total expenditure proposed exceeds £150k (taking account of the previous DD), a Mayoral Decision is being requested.

Phase 1 of this programme is a discrete programme of work which will allow key live services to be moved offsite and thereby provide definable business benefits as outlined in this report. Future phases are referred to in this report but will be subject to separate approvals.
