Transport for LondonData Centre Rationalisation Architect
Aug. 2013 - Mar. 2014London, BroadwayThe role at Tfl is to audit existing train stations within London underground and virtualise the hosted service to primary data centre. The servers will host a number of different services from CCTV to ticketing & booking systems. The process to virtualise or decommission a service would be the following: - • Reviewing the current design of the hosted service within the Tfl Infrastructure.
• Finding the correct business and applications owners for these services prior to migration.
• Planning the migration to the virtual platform.
• Checking for any dependencies on the platform before migration.
• Auditing the applications hosted and installed on each node prior to migration.
• Submitting the Change Request for approval for the planned migration.
• Doing the migration and then handed the P2V’ed services back to the customer.
• After 30 days, submitting the change to decommission the physical node. Operating system platforms: - Microsoft NT4 Server, Windows 2000, 2003 (R2), Window 2008,Windows 2012
Re-platform hosted services from: Windows 2000 server to 2008 or 2012 server The virtualisation platform is VMware, ESX hosts 5.02. With SRM and vMotion Also re-designing an upgrade path if the server/service couldn’t be migrated via the P2V process. I would have design an upgrade path for the services hosted. Operating systems migrated or re-plat formed: Microsoft NT4, 2000, 2003-R2, 2008-R2, Suse, Sco-Unix.
Business Applications migrated or re-plat formed: SQL 2005, 2008, MySQL, SharePoint, CRM, Metronet, Surface, FUSE (Fire Alarming Reporting System), AMIS, Source (Tfl Internal and External Intranet), etc. Once the servers and services have been migrated to the preferred Data Centre, the legacy site would be marked as complete. This saves the business infrastructure cost i.e. (Building rent, electricity, and server hardware maintenance).
