- 3. Cloud Today
- 4. The road to cloud… • “The network is the computer” – Sun (1988) • .dotcom era in 2000 – Outsource IT services and infrastructure • Web email (Yahoo, Hotmail, Gmail) & YouTube • Salesforce.com and Amazon Web Services • Nicholas Carr – The “Big Switch” 2008 and “IT is dead” • Mobile Apps on hundreds of Million app‐capable smart devices
- 5. What are we seeing in Cloud? • Moved from buzzword and hype to real technology • Move from “When” to “How” • Agreements on Various Definitions – Payment Model • Software as a Service (SaaS) • Platform as a Service (PaaS) • Infrastructure as a Service (IaaS) – Delivery Model • Public, Private, Hybrid Clouds
- 6. Comparing the Delivery Vehicles Traditional Delivery Cloud Based Applications Software‐as‐a‐Service (SaaS) Development Tools Development‐as‐a‐Service (Daas) Middleware Platform‐as‐a‐Service (PaaS) Infrastructure and Infrastructure‐as‐a‐Service Hardware (IaaS)
- 7. Cloud trends in 2011 – Private Clouds • The move to a hybrid world – Large enterprises build out private clouds and leverage public clouds for workloads such as • Dev/Test, Archiving, Disaster Recovery, Redundancy, Web‐Serving – Gartner expects large enterprises to have a dynamic sourcing team for cloudsourcing and management – Focus on selecting the right building blocks
- 8. Cloud trends in 2011 – Big Data • Focus on “Big Data” and Databases – The old paradigm of RDBMS is no longer valid – Cloud‐native database • “No SQL” • Graph Databases • Hardoop HBase • Database.com – Transactional data processing and analysis • Cloud is great for “Data‐as‐a‐service” combined with Compute and Storage from Infrastructure as a service
- 9. Cloud trends in 2011 – Truly Global • Cloud allows Emerging markets to levels the playing field – New business models and access to markets – No previous IT investment or Legacy baggage • US based cloud providers are going after Asia and EMEA markets
- 10. Cloud Platform Design Guidelines • Modular architecture – Compute, Storage, Management, Network • Homogeneous pool of compute and storage with uniform connectivity • Compute – – No more than 16 “small” machine instances per server – Managed/VLAN networking mode to ensure mutli‐tenancy network security
- 11. Cloud Platform Design Guidelines ‐ Storage • Single large store for all cloud storage – DAS, SAN, NAS • Block Storage (EBS) vs Application Aware(S3) • Separate persistent vs non‐persistent • Use SSD and Flash to improve performance – Compute DAS for caching VM images – Meta‐data Store • Storage based on “cheap good enough storage” (JBODs)
- 12. Design Guidelines ‐ Redundancy • Redundancy moves from hardware into the software and application • Most public clouds builders lack network, power and disk redundancy • PDU and Rack Switch failure will take down lots of servers • Flatness at Edges – Avoid tiers when possible
- 13. Design Guidelines – Hyperscale • Simple network routing and configuration • Higher Density • Minimize shared physical infrastructure • Modularity, consistency and simplicity is the key • Have the ability to add capacity to the datacenter rapidly
- 14. Cloud Datacenter Key Design Points • High x86 server & storage density – Designed to scale • Build To Order flexibility – Broad range of configurations • Eco‐Logical™ focus on lowering OpEx: – Low power consumption – High efficiency AC and DC power supplies – Innovative, effective cooling techniques
