Cloud computing
- 1. DISRUPTIVE INNOVATION & ENABLING TECHNOLOGY Cloud Computing Author: Tushprit Singh 0501323108 IT1 (7 th Semester)
- 2. The “Cloud” = 10X Improvements Ease of Use Scalability Risk Reliability Cost
- 3. Ease of Use Deploy infrastructure with a mouse or API No cabling, screwdrivers, racking, unboxing, buying Middle of the night Do it yourself remotely from anywhere anytime
- 4. Scalability See Ease of Use Control your infrastructure with your app Nothing to purchase and take delivery on Instant
- 5. Risk Nothing to buy Cancel immediately Change instantly, even operating systems Throw it out Rebuild it instantly after testing RISK
- 6. Reliability Based on enterprise grade hardware Design for failures: Automatically spin up replacements Use multiple clouds
- 7. Cost “ Turn off the lights” = turn off servers you aren’t using Ex: Turn off development and test environments Pay for only what you use No need to buy in advance Zero Capital Outlay No contracts
- 8. “ Breaking the Dam(n!)” Colocation – 1 st step to outsourcing Managed Hosting – dedicated servers managed by 3 rd party take some pain away Cloud Hosting – Lower cost, easier, lower risk, more reliable
- 9. Traditional Hosting Costs Continue to Grow High CapEx Low facility asset utilization (55%) High Depreciation (42-50%) Power/Cooling costs > Server Costs Not “Green” 30% hardware obsolescence - Source: Forbes.com, Kenneth Brill, “Servers: Why Thrifty Isn’t Nifty” Source: Forbes.com, “Servers: Why Thrifty Isn’t Nifty”
- 10. UNDERSTANDING HOW EXPERTS VIEW “CLOUD COMPUTING” Multiple Definitions
- 11. Forrester Research “ A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption 1 ” 1- “Is Cloud Computing Ready for The Enterprise?” Forrester Research, Inc.
- 12. Other Definitions “ Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services.” – IBM press release on “Blue Cloud” “… a hosted infrastructure model that delivers abstracted IT resources over the Internet” – Thomas Weisel Partners LLC from “Into the Clouds: Leveraging Data Centers and the Road to Cloud Computing” “ Cloud computing describes a systems architecture. Period. This particular architecture assumes nothing about the physical location, internal composition or ownership of its component parts.” – James Urquhart blog post
- 13. Multiple Graphic Descriptions of the “Cloud”
- 14. PERSPECTIVE VIEW OF “CLOUD COMPUTING” Redefining the definition
- 15. Defining the Segments SaaS Software as a Service Storage as a Service PaaS – Platform as a Service IaaS – Infrastructure as a Service
- 16. Colo vs. Managed vs. Cloud Hosting Colocation Managed Cloud Time Weeks to Months Days to Weeks Minutes Scalability Slowest, Rigid & Costly Slower, somewhat flexible, Costly Instant, Flexible, Pay-per-usage Cost High CapEx Costly, sometimes month/year contracts, no CapEx No contracts, usage based, no upfront costs “ Green” Low Low High - virtualized Pricing model Buy Servers & Colo costs whether used or not Rent Servers & Hosting costs whether used or not Rent based on usage only
- 17. Hosting Industry Ripe for Change Technology has evolved People demand more control Instant gratification In-house too costly from CapEx and Human Capital Colocation for those who want to be physically there Managed is not dynamic enough Cloud Computing -“Enabling Technology” to move from Traditional Hosting to Cloud Hosting
- 18. The Cloud’s “Snowball Effect” Maturation of Virtualization Technology Virtualization enables Compute Clouds Compute Clouds create demand for Storage Clouds Storage + Compute Clouds create Cloud Infrastructure Cloud Infrastructure enables Cloud Platforms & Applications Multiple Cloud types lead to Cloud Aggregators Niche requirements enable Cloud Extenders
- 19. The “Cloud Pyramid” Build upon a foundation Layers equate structure Building blocks: Infrastructure, Platforms, Applications Breadth vs. Niche
- 20. The “Cloud Pyramid” Inversed 1000’s of Cloud Applications currently Handful of Cloud Platforms Elite group of Cloud Infrastructure providers # of Marketplace providers
- 21. Cloud Computing is… … virtualized compute power and storage delivered via platform-agnostic infrastructures of abstracted hardware and software accessed over the Internet. These shared, on-demand IT resources, are created and disposed of efficiently, are dynamically scalable through a variety of programmatic interfaces and are billed variably based on measurable usage.
- 22. Cloud “Applications” SaaS resides here Most common Cloud / Many providers of different services Examples : SalesForce, Gmail, Yahoo! Mail, Quicken Online Advantages : Free, Easy, Consumer Adoption Disadvantages : Limited functionality, no control or access to underlying technology
- 23. Cloud “Platforms” “ Containers” “ Closed” environments Examples : Google App Engine, Heroku, Mosso, Engine Yard, Joyent or Force.com (SalesForce Dev Platform) Advantages : Good for developers, more control than “Application” Clouds, tightly configured Disadvantages : Restricted to what is available, other dependencies
- 24. Cloud “Infrastructure” Provide “Compute” and “Storage” clouds Virtualization layers (hardware/software) Examples : Amazon EC2, GoGrid, Amazon S3, Nirvanix, Linode Advantages : Full control of environments and infrastructure Disadvantages : premium price point, limited competition
- 25. Cloud “Extenders” (Wild Card) Provides extension to Cloud Infrastructure and Platforms with basic functionality Examples : Amazon SimpleDB, Amazon SQS, Google BigTable Advantages : Extends functionality of Compute & Storage Clouds to integrate with legacy system or other clouds Disadvantages : Sometimes requires use of specific Platforms or Infrastructure
- 26. Cloud “Aggregators” (Wild Card) Sits on top of various Cloud Infrastructures for management Examples : RightScale, Appistry Advantages : Provides more options for Cloud environments Disadvantages : Dependent on Cloud Providers
