This document discusses cloud computing and trends in internet infrastructure. It describes three levels of cloud computing: level 1 involves distributing hardware components across multiple servers to increase reliability, level 2 adds a second data center for redundancy, and level 3 provides platform-agnostic application delivery that is independent of hardware or location. The document also notes challenges of cloud computing like the difficulty and costs of replication across data centers and a lack of application vendor support for virtualized environments.

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