Estimated at $6.2bn revenue for 2014, hosting 11.6m websites/business globally (end 2013), growth 100% in Market commentators indicate it may well be spun out into a separate entity Proposed use of AWS Dublin, i.e. within the EU / subject to EU laws Governance & quality AWS has ISO 9001 Quality Management Certification AWS is compliant with PCI DSS and ISO Gartner Magic Quadrant for Infrastructure as a Service Data Protection Within Dublin complex there are two availability zones (AZ), Data will be copied (for backup & DR) across AZ AWS storage platforms have % durability and data copied across multiple facilities and multiple devices 10 Public 10

11 Some prompts for discussion Are Legacy environments outdated Never a better time to modernise A sector slow to change Reform (open water) will force the pace Will the dependency on IT increase Will IT spend have to go up The experience and talent needed Is the aas journey the right one? 11 Public 11
