Transcript

  • 1. MISA – CLOUD 101Garth Reid©2010 Hewlett-Packard Development Company, L.P.The information contained herein is subject to change without notice
  • 2. Origin of the term “Cloud Computing”• “Comes from the early days of the Internet where we drew the network as a cloud… we didn’t care where the messages went… the cloud hid it from us” – Kevin Marks, Google• First cloud around networking (TCP/IP abstraction)• Second cloud around documents (WWW data abstraction)• The emerging cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms – (“muck” as Amazon’s CEO Jeff Bezos calls it) 2 2
  • 3. A Working Definition of Cloud Computing • Cloud computing is a model for enabling convenient, on- demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. • This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.3 3
  • 4. 5 Essential Cloud Characteristics • On-demand self-service • Broad network access • Resource pooling – Location independence • Rapid elasticity • Measured service 4
  • 5. 3 Cloud Service Models• Cloud Software as a Service (SaaS) –Use provider’s applications over a network• Cloud Platform as a Service (PaaS) –Deploy customer-created applications to a cloud• Cloud Infrastructure as a Service (IaaS) –Rentprocessing, storage, network capacity, and other fundamental computing resources• To be considered “cloud” they must be deployed on top of cloud infrastructure that has the key characteristics 5
  • 6. Service Model Architectures 6
  • 7. IaaS PaaS SaaS
  • 8. 4 Cloud Deployment Models• Private cloud – enterprise owned or leased• Community cloud – shared infrastructure for specific community• Public cloud – Sold to the public, mega-scale infrastructure• Hybrid cloud – composition of two or more clouds 8
  • 9. Common Cloud Characteristics• Cloud computing often leverages: – Massive scale – Homogeneity – Virtualization – Resilient computing – Low cost software – Geographic distribution – Service orientation – Advanced security technologies 9
  • 10. General Security Advantages• Shifting public data to a external cloud reduces the exposure of the internal sensitive data• Cloud homogeneity makes security auditing/testing simpler• Clouds enable automated security management• Redundancy / Disaster Recovery 10
  • 11. Balancing Threat Exposure and Cost Effectiveness• Private clouds may have less threat exposure than community clouds which have less threat exposure than public clouds.• Massive public clouds may be more cost effective than large community clouds which may be more cost effective than small private clouds.• Doesn’t strong security controls mean that I can adopt the most cost effective approach? 11
  • 12. Provisioning Service• Advantages – Rapid reconstitution of services – Enables availability • Provision in multiple data centers / multiple instances – Advanced honey net capabilities• Challenges – Impact of compromising the provisioning service 12
  • 13. Data Storage Services• Advantages –Data fragmentation and dispersal –Automated replication –Provision of data zones (e.g., by region) –Encryption at rest and in transit –Automated data retention• Challenges –Isolation management / data multi-tenancy –Storage controller • Single point of failure / compromise? –No control over DR? 13
  • 14. The ‘Why’ and ‘How’ of Cloud Migration • There are many benefits that explain why to migrate to clouds – Costsavings, power savings, green savings, increased agility in software deployment • Cloud security issues may drive and define how we adopt and deploy cloud computing solutions 14
  • 15. Possible Effects of Cloud Computing• Small enterprises use public SaaS and public clouds and minimize growth of data centers• Large enterprise data centers may evolve to act as private clouds• Large enterprises may use hybrid cloud infrastructure software to leverage both internal and public clouds• Public clouds may adopt standards in order to run workloads from competing hybrid cloud infrastructures 15
  • 16. Data Centre Trends• Fewer, but larger Data Centres• Is investment in DataCentres required?• CPU / Memory – densities / Moores law 16
  • 17. Business and IT are on different trajectories tocloud• Business is adopting cloud 5x faster than IT – Drivers: speed, flexibility, economics• While CIO’s are concerned about cloud risk – 79% concerned about vendor lock-in2 – 75% demand high guarantees for performance & availability2 – 70% have security top of mind1 – 63% prefer integration of cloud & on-premises IT services21.

  • 18. The strategic role of the CIO is changingBecoming a builder and broker of services Transform Manage and secure legacy infrastructure and across legacy applications applications and processes and cloud assets Build Consume on-premises off-premises cloud services services securely Traditional Private Public18 4/17/2012
  • 19. Customers will evolve to the cloud at differentspeeds Business Transformation to ”Instant-On”19
  • 20. What a cloud should deliver Broad ecosystem of OS’s, hypervisors, apps Unified service delivery Automated infrastructure-to-app lifecycle management Public, private, hybrid Scalability Security20
  • 21. Build and manage cloud servicesAutomating the entire lifecycle with Cloud Cloud APIs • Billing/chargeback • Approval flows • Other processes21
