Cloud Computing

  1. 1. Cloud Computing <ul><li>The Evolution of Internet Infrastructure </li></ul><ul><li>Ed Byrne - 2008 </li></ul><ul><li>[email_address] </li></ul>
  2. 2. Overview <ul><li>Components of Internet Infrastructure </li></ul><ul><li>Trends in Internet Infrastructure </li></ul><ul><li>Introduction to Cloud Computing </li></ul><ul><li>3 Levels of Cloud Computing </li></ul><ul><li>Challenges of Cloud Computing </li></ul><ul><li>Wrap-Up : About Hosting365 </li></ul>
  3. 3. Components of Internet Infrastructure <ul><li>‘ Internet Infrastructure is what makes the Internet go’ </li></ul><ul><li>Data Centres </li></ul><ul><li>Network </li></ul><ul><li>Computer Equipment </li></ul><ul><li>Storage Services </li></ul><ul><li>Application Layer </li></ul>
  4. 4. Trends in Internet Infrastructure <ul><li>Data Centres :- </li></ul><ul><ul><li>Massive Build Cost. </li></ul></ul><ul><ul><li>Increasing Capacity Requirements. </li></ul></ul><ul><ul><li>Environmental Issues. </li></ul></ul><ul><ul><li>Energy Concerns. </li></ul></ul><ul><ul><li>Huge Increase is DC Demand due to Internet Growth and move of Office IT to Hosted Model. </li></ul></ul>
  5. 5. <ul><li>Computer Equipment (Servers) :- </li></ul><ul><ul><li>Smaller and more Powerful. </li></ul></ul><ul><ul><li>Higher Power Density and more Cooling required. </li></ul></ul><ul><ul><li>Low Utilisation of Dedicated Equipment. </li></ul></ul><ul><ul><li>Ability to Remotely Monitor & Manage Equipment. </li></ul></ul>Trends in Internet Infrastructure
  6. 6. Trends in Internet Infrastructure <ul><li>Storage Services :- </li></ul><ul><ul><li>Cost per MB went to cost per GB. Now cost per TB. </li></ul></ul><ul><ul><li>Price of storage dropping continuously. </li></ul></ul><ul><ul><li>Growth is storage requirements outpacing pricing. </li></ul></ul><ul><ul><li>Speed of Storage Connectivity allowing more creative ways to manage and provision GB’s. </li></ul></ul><ul><ul><li>Solid State SANs. Storage Virtualisation. </li></ul></ul>
  7. 7. Trends in Internet Infrastructure <ul><li>Application Layer :- </li></ul><ul><ul><li>Virtualisation </li></ul></ul><ul><ul><ul><li>Maximises Server and Storage Utilisation. </li></ul></ul></ul><ul><ul><ul><li>Lowers Carbon Footprint. </li></ul></ul></ul><ul><ul><ul><li>Improves Manageability of Infrastructure Architecture. </li></ul></ul></ul>
  8. 8. Introduction to Cloud Computing <ul><li>Not to be confused with : Grid Computing or Utility Computing. </li></ul><ul><li>At Hosting365, we define Cloud Computing as: </li></ul><ul><ul><li>Level 1: Not reliant on single hardware components for operation. </li></ul></ul><ul><ul><li>Level 2: Independent of single Data Centre facility. </li></ul></ul><ul><ul><li>Level 3: Platform agnostic application delivery. </li></ul></ul>
  9. 9. Why Cloud Computing? <ul><li>Scalable. </li></ul><ul><li>Flexible. </li></ul><ul><li>Reliable. </li></ul><ul><li>Fast Setup. </li></ul><ul><li>Affordable Enterprise Solution. </li></ul><ul><li>Environmentally More Efficient (Friendly). </li></ul>
  10. 10. Cloud Computing : Level 1 <ul><li>Dumb Server Deployment </li></ul><ul><ul><li>H365: 128 Blade Servers in 6 Enclosures. </li></ul></ul><ul><ul><li>H365: RAM + Processors only. Virtual Connect modules. </li></ul></ul><ul><li>Storage Area Network </li></ul><ul><ul><li>H365: 21 TB SAN, trays populated with 146 GB 15krpm drives. </li></ul></ul><ul><ul><li>H365: Fibre Channel connected controllers to blade enclosures. </li></ul></ul><ul><li>Intelligent Management of Infrastructure </li></ul><ul><ul><li>Blade Management Console. </li></ul></ul><ul><ul><li>Virtualised Platform Management. </li></ul></ul><ul><ul><li>VMware for Servers. IBM SVC for Storage. </li></ul></ul><ul><li>Result: Hardware Independence. </li></ul><ul><ul><li>Single components can fail with minor service interruption. Extremely price attractive for this level of High Availability. </li></ul></ul>
  11. 11. Cloud Computing : Level 2 <ul><li>Independent of the Data Centre </li></ul><ul><li>Level 1 + Second (or more) Data Centre. </li></ul><ul><li>Replication to DC-2 of Storage Services (sync, a-sync, pit) </li></ul><ul><li>Duplication of OS Environment (image based, can be live geo-DNS, near-live replication, or config-snapshot) </li></ul><ul><li>Cost dependent of level of tolerance for fail-over. </li></ul>
  12. 12. Cloud Computing : Level 3 <ul><li>Platform Agnostic Application Delivery </li></ul><ul><li>Forget the DC. Forget the Service Provider. </li></ul><ul><li>Standardise on Server Image and Storage Service. </li></ul><ul><li>Utilise Cross-Platform ‘Cloud APIs’. Utilise Cloud based DNS. </li></ul><ul><li>Manage Environment using Monitoring Tool for Service Providers and live-select provider. </li></ul><ul><ul><li>Manage based on Uptime, Price, Speed, Requirements. </li></ul></ul><ul><li>H365 Solution: NetOS </li></ul>
  13. 13. Cloud Computing Challenges <ul><li>Replication is hard, and expensive. Customers won’t pay for it as standard. It doesn’t really work outside of county / province distances (300km). </li></ul><ul><li>A lot of application vendors don’t yet have licensing policies for running in a virtualised environment. </li></ul><ul><li>It’s a new area - there’s not a lot of consultative expertise to call on. </li></ul><ul><li>Realising that there needs to be an industry standard API set and that means you may not control your customers services forever. </li></ul>
