  3. UK G-Cloud & App Store • In order to reduce cost & carbon without compromising service quality, UK public sector wants: • Like-for-like service comparability • Resources pooling from multiple providers • Workload pooling for peak load curtailment • Pay-as-you-use billing • Access to cost benefits of massively automated ICT services • Interoperability to avoid vendor lock-in • Likely answer: A government ICT services marketplaceinto a hybrid of several private community clouds.

  6. Possible G-Cloud architecture

  7. G-Cloud maturity model

  8. Cloud Computing and Information Assurance (Security) • “Cloud” often considered insecure, but why? • In 8 years Memset have had zero VM break-outs. • Can be more secure, eg. security through obscurity. • Bigger concern is perhaps organisational threat. • Though network virtualisation is okay, GCHQ has not certified the hypervisor layer as a suitable barrier. • Physical segregation still required for some services.

  10. A cloud for each Impact Level (IL)

  11. Security summary • Some public cloud suitable for IL0, perhaps IL1 & 2 • Secure G-Cloud: Probably 1 private cloud per IL > 1 • Additional complicating factors: • 3 IL aspects: Confidentiality / Integrity / Assurance • IL-threat combinations • Risk aggregation • All tractable problems, though!
